If your OBD-II scanner displays P0082, your vehicle’s Engine Control Module (ECM) or Powertrain Control Module (PCM) has detected a lower-than-expected electrical signal in the Bank 2 intake valve control solenoid circuit.
The generic OBD-II definition for P0082 is:
Intake Valve Control Solenoid Circuit Low Bank 2
Depending on the vehicle manufacturer or scan tool, the description may appear as:
- Intake Valve Control Solenoid Circuit Low Bank 2
- Intake Valve Timing Control Solenoid Circuit Low Bank 2
- Intake Camshaft Control Solenoid Circuit Low Bank 2
- Intake Oil Control Valve Circuit Low Bank 2
- Bank 2 Intake VVT Solenoid Circuit Low
- Intake Valve Control Solenoid Short to Ground Bank 2
P0082 belongs to the Bank 2 intake valve control solenoid code family:
- P0081: General circuit malfunction
- P0082: Circuit low
- P0083: Circuit high
The intake valve control solenoid is part of the engine’s variable valve timing system. It regulates pressurized engine oil flowing to the Bank 2 intake camshaft actuator or cam phaser.
The PCM may store P0082 when it detects:
- A control circuit shorted to ground
- An internally shorted VVT solenoid
- Excessive solenoid current
- Missing or reduced supply voltage
- Damaged wiring
- Corroded connector terminals
- A failed PCM output driver
P0082 is primarily an electrical circuit code. Low or contaminated engine oil can cause additional VVT performance problems, but it does not automatically explain a circuit signal that remains electrically low.
Possible symptoms include:
- Check Engine Light
- Rough or unstable idle
- Poor acceleration
- Reduced engine power
- Increased fuel consumption
- Hesitation
- Hard starting
- Engine stalling
- Bank 2 misfires
- Failed emissions inspection
- No obvious drivability symptoms

What Does P0082 Mean?
P0082 means the PCM has detected an electrical value below its calibrated operating range in the Bank 2 intake valve control solenoid circuit.
The affected circuit may include:
- Bank 2 intake valve control solenoid
- Solenoid power-supply wire
- PCM control or ground wire
- Electrical connector
- Shared actuator fuse
- Engine-control relay
- Engine wiring harness
- PCM output driver
The PCM normally controls the intake VVT solenoid using an electrical on/off or pulse-width-modulated command.
When commanded, the solenoid changes oil flow to the intake camshaft actuator. The camshaft actuator then advances or retards intake valve timing.
If the monitored voltage remains too low, the PCM may determine that the circuit is:
- Shorted to ground
- Drawing excessive current
- Missing supply voltage
- Electrically shorted inside the solenoid
- Permanently held low by a damaged driver
The PCM may disable Bank 2 variable valve timing and place the engine into a failsafe strategy until the circuit is repaired.
What Is Bank 2?
Bank 2 is the side of the engine that does not contain cylinder number 1.
Bank 2 is found on engines with two cylinder banks, including many:
- V6 engines
- V8 engines
- V10 engines
- V12 engines
- Horizontally opposed engines
Inline engines usually have only one cylinder bank and therefore do not normally have a Bank 2.
Bank 2 is not automatically:
- Driver side
- Passenger side
- Left side
- Right side
- Front side
Its physical location depends on the manufacturer’s cylinder-numbering arrangement.
Use:
- Factory service information
- Cylinder-numbering diagram
- Repair database
- Underhood emissions label
to identify Bank 2 correctly.
Replacing the solenoid on the wrong bank is a traditional method of proving that the new part was not the problem.
What Is an Intake Valve Control Solenoid?
The intake valve control solenoid is an electrically operated oil-control valve used by the variable valve timing system.
It may also be called:
- Intake VVT solenoid
- Intake oil control valve
- Intake valve timing control solenoid
- Intake camshaft actuator solenoid
- VCT solenoid
- CVVT oil control valve
- Camshaft position actuator solenoid
- Variable cam timing solenoid
The solenoid controls oil flowing toward the intake camshaft actuator.
The PCM may change intake camshaft timing based on:
- Engine speed
- Engine load
- Throttle position
- Coolant temperature
- Oil temperature
- Vehicle speed
- Requested torque
- Emissions requirements
Variable intake camshaft timing can improve:
- Low-RPM torque
- Midrange response
- High-RPM power
- Fuel economy
- Idle quality
- Cold-start performance
- Turbocharger response
- Exhaust emissions
P0082 does not necessarily mean the camshaft actuator or timing chain has failed.
It means the PCM has detected a low electrical condition in the circuit controlling the Bank 2 intake solenoid.
How Variable Valve Timing Works
A typical intake variable valve timing system includes:
- Engine oil supply
- Oil galleries in the cylinder head
- Intake valve control solenoid
- Intake camshaft actuator or phaser
- Camshaft position sensor
- Crankshaft position sensor
- PCM control logic
When the PCM requests an intake camshaft adjustment:
- The PCM changes the VVT solenoid duty cycle.
- The solenoid redirects engine oil.
- Oil pressure enters the camshaft actuator.
- The actuator rotates the camshaft relative to the timing sprocket.
- The camshaft sensor reports the new position.
- The PCM compares desired timing with actual timing.
If P0082 is present, the PCM may be unable to control the solenoid properly and may disable VVT on Bank 2.
Loss of variable valve timing can reduce acceleration and fuel economy because the engine can no longer optimize valve timing for changing speed and load conditions.
How the Intake Valve Control Solenoid Circuit Works
Many intake VVT solenoids use two electrical terminals.
A common circuit design includes:
- Battery or ignition voltage supplied to one terminal
- PCM-controlled ground on the other terminal
The PCM often controls the ground circuit using pulse-width modulation.
Pulse-width modulation allows the PCM to regulate:
- Solenoid current
- Internal spool-valve position
- Oil flow
- Camshaft actuator movement
The PCM may monitor:
- Control-circuit voltage
- Solenoid current
- Coil resistance
- Driver feedback
- Commanded duty cycle
- Actual camshaft response
Depending on the circuit design, a low condition may be detected when:
- Voltage remains near ground
- Current draw is excessive
- The solenoid coil resistance is too low
- The PCM driver cannot release the circuit
- Supply voltage is missing
- The control wire is grounded
What Does “Circuit Low” Mean?
“Circuit low” refers to the electrical signal, not the engine-oil level or camshaft position.
It does not necessarily mean:
- Engine oil is low
- Oil pressure is low
- Intake valve lift is low
- Camshaft timing is retarded
- Battery charge is low
It means the PCM sees circuit voltage or electrical feedback below its expected range.
Common circuit-low causes include:
- Control wire shorted to ground
- Solenoid coil shorted internally
- Excessive current draw
- Missing power supply
- Connector terminals shorted together
- PCM driver permanently grounded
- Severe voltage loss in the supply circuit
The correct interpretation depends on whether the PCM controls the power side or ground side of the solenoid circuit.
Always consult the vehicle-specific wiring diagram before testing or applying voltage.
P0081 vs P0082 vs P0083
| Code | Description | Typical Meaning |
| P0081 | Intake Valve Control Solenoid Circuit Bank 2 | General circuit malfunction |
| P0082 | Intake Valve Control Solenoid Circuit Low Bank 2 | Circuit voltage below specification |
| P0083 | Intake Valve Control Solenoid Circuit High Bank 2 | Circuit voltage above specification |
Generally:
- P0081 may indicate an unspecified open, short, or circuit failure.
- P0082 commonly leads toward a grounded control wire, shorted coil, or missing supply.
- P0083 commonly leads toward an open circuit, disconnected solenoid, or short to voltage.
P0082 vs P0076
P0076 is defined as:
Intake Valve Control Solenoid Circuit Low Bank 1
P0082 is defined as:
Intake Valve Control Solenoid Circuit Low Bank 2
The difference is the affected cylinder bank:
- P0076 affects Bank 1.
- P0082 affects Bank 2.
If the engine uses identical intake VVT solenoids on both banks, Bank 1 can provide a useful comparison for:
- Coil resistance
- Supply voltage
- Current draw
- Control waveform
- Commanded and actual timing
Confirm that both parts and circuit designs are identical before comparing or swapping components.
P0082 vs P0020
P0020 is generally defined as:
“A” Camshaft Position Actuator Circuit Bank 2
P0082 is defined as:
Intake Valve Control Solenoid Circuit Low Bank 2
Depending on the manufacturer, both codes may involve the same Bank 2 intake camshaft oil-control solenoid.
The difference is that:
- P0020 is a broader actuator circuit code.
- P0082 specifically identifies a low circuit condition.
Vehicle-specific service information should determine the correct diagnostic path.
How the PCM Detects P0082
The PCM may store P0082 when:
- Control-circuit voltage remains below its limit
- Solenoid current is higher than expected
- The control wire is shorted to ground
- The solenoid coil has unusually low resistance
- Solenoid supply voltage is missing or severely reduced
- Driver feedback does not match the commanded state
- The fault remains present for a calibrated period
The test may run:
- With the ignition on
- While the engine is running
- When the PCM commands VVT operation
- During a defined RPM range
- After oil temperature reaches a threshold
- Continuously on some systems
When P0082 is detected, the PCM may:
- Illuminate the Check Engine Light
- Disable Bank 2 intake camshaft adjustment
- Store freeze-frame data
- Enter failsafe mode
- Reduce engine performance
Symptoms of P0082
Possible symptoms include:
- Check Engine Light
- Rough idle
- Unstable idle speed
- Engine hesitation
- Poor throttle response
- Reduced acceleration
- Loss of low-speed torque
- Reduced high-RPM power
- Increased fuel consumption
- Hard starting
- Extended cranking
- Engine stalling
- Bank 2 misfires
- Increased emissions
- Failed emissions inspection
- Reduced-power mode
- No noticeable symptoms
The symptoms depend on:
- Engine design
- Default Bank 2 camshaft position
- Whether the solenoid remains energized
- Whether Bank 1 VVT remains functional
- Oil condition
- Camshaft actuator condition
- Presence of additional timing codes
Some vehicles may continue to run fairly normally while VVT is disabled.
Others may make Bank 2 feel as though it missed the meeting where both sides of the engine agreed to operate the same way.
Can P0082 Cause a Rough Idle?
Yes.
Incorrect intake camshaft timing can affect:
- Cylinder filling
- Manifold vacuum
- Combustion stability
- Residual exhaust dilution
- Idle airflow requirements
Possible results include:
- Rough idle
- Surging
- Bank 2 misfires
- Stalling
- Poor cold-start operation
However, rough idle may also result from:
- Vacuum leaks
- Ignition faults
- Fuel-injector problems
- Low compression
- Mechanical timing errors
- Camshaft sensor faults
Compare Bank 1 and Bank 2 camshaft data before concluding that P0082 explains every engine symptom.
Can P0082 Cause Poor Acceleration?
Yes.
The variable intake timing system helps optimize airflow and torque across different engine speeds.
If Bank 2 VVT is disabled, the engine may lose:
- Low-RPM torque
- Midrange response
- High-RPM breathing
- Turbocharger response
- Overall efficiency
Reduced acceleration and poorer fuel economy are common when a PCM disables variable valve timing because of a solenoid circuit fault.
Common Causes of P0082
1. Internally Shorted Bank 2 Intake VVT Solenoid
The solenoid’s internal coil may short between windings.
This can cause:
- Resistance below specification
- Excessive current draw
- Low circuit voltage
- Blown fuse
- PCM driver shutdown
- P0082
An internally shorted solenoid is one of the most likely direct causes of a circuit-low fault.
2. PCM Control Wire Shorted to Ground
The PCM control wire may rub through its insulation and contact:
- Cylinder head
- Valve cover
- Engine bracket
- Intake manifold support
- Heat shield
- Metal harness clip
- Ground wire
A short to ground may hold the circuit permanently low.
The result may be:
- Solenoid constantly energized
- Solenoid disabled by driver protection
- Blown fuse
- Damaged PCM driver
- Bank 2 timing control disabled
3. Melted Engine Wiring
The Bank 2 intake solenoid wiring may run near:
- Exhaust manifold
- Turbocharger
- EGR pipe
- Cylinder head
- Hot coolant pipe
- Catalytic converter on compact engine layouts
Heat can:
- Melt insulation
- Expose conductors
- Short wires to ground
- Short adjacent circuits together
- Make wiring brittle
Inspect for missing heat shields and incorrect harness routing.
4. Chafed Wiring Harness
The harness may rub against:
- Valve-cover edge
- Cylinder-head casting
- Engine lifting bracket
- Intake manifold
- Wiring tray
- Metal retaining clip
Engine movement may eventually wear through the insulation.
The harness does not need to look dramatically destroyed. One tiny exposed section touching the cylinder head is enough to convince electricity that it has found a shorter route.
5. Failed Intake Valve Control Solenoid
The solenoid may fail because of:
- Electrical coil damage
- Internal short
- Heat
- Age
- Vibration
- Oil intrusion
- Manufacturing defect
Electrical testing may reveal:
- Resistance below specification
- Excessive current draw
- Short to the solenoid body
- Unstable operation when hot
6. Corroded Connector Terminals
Corrosion can cause:
- Voltage loss
- Terminal bridging
- Unstable current
- Poor PCM feedback
- Intermittent circuit-low behavior
Inspect for:
- Green corrosion
- White oxidation
- Darkened terminals
- Water
- Oil
- Bent pins
- Damaged seals
- Loose terminal fit
7. Oil-Contaminated Connector
Oil may enter the connector because of:
- VVT solenoid seal failure
- Valve-cover leak
- Oil migration through the component
- Harness contamination
Oil may:
- Trap dirt
- Damage connector seals
- Reduce terminal contact
- Wick into the wiring harness
- Contribute to intermittent faults
Clean the connector and repair the oil leak.
Otherwise, the connector will simply return to its role as a tiny electrical oil bath.
8. Water Intrusion
Water may enter through:
- Damaged connector seal
- Cracked connector housing
- Improper pressure washing
- Unsealed wiring repair
- Coolant leak near the harness
Moisture may bridge the control and ground terminals, pulling the circuit low.
9. Connector Terminals Shorted Together
Bent terminals, moisture, damaged insulation, or metal debris may connect:
- Control to ground
- Supply to control
- Adjacent VVT circuits
Inspect the connector carefully before replacing the solenoid or PCM.
10. Incorrectly Wired Replacement Connector
A replacement pigtail may have:
- Reversed wires
- Incorrect terminal cavities
- Poor crimps
- Wrong terminal size
- Missing weather seals
Verify the connector pinout using the wiring diagram.
Matching wire colors is helpful only when the replacement supplier and every previous repairer shared the same interpretation of those colors.
11. Missing Solenoid Power Supply
Depending on circuit design, a missing power supply can produce a low monitored value.
Possible causes include:
- Blown fuse
- Failed relay
- Open supply wire
- Corroded splice
- Loose fuse-box terminal
- Engine power-distribution problem
If several actuators have circuit codes, inspect the shared power source before replacing multiple solenoids.
12. Blown Fuse
A fuse may blow because of:
- Internally shorted VVT solenoid
- Supply wire shorted to ground
- Melted engine harness
- Another shorted actuator on the shared circuit
- Incorrect electrical repair
Do not repeatedly replace the fuse without locating the short.
A fuse is a warning that excessive current exists. It is not a recurring maintenance item.
13. Failed Engine-Control Relay
A damaged relay may cause:
- Missing voltage
- Intermittent power
- Excessive voltage drop
- Multiple actuator codes
Inspect the relay when several engine-control components lose voltage together.
14. High Resistance in the Supply Circuit
Although P0082 is a circuit-low code, excessive resistance on the supply side may reduce voltage enough to trigger the fault.
Possible causes include:
- Corroded splice
- Weak relay contact
- Partially broken wire
- Heat-damaged terminal
- Loose fuse connection
- Poor previous repair
A continuity test may pass while the circuit still fails under load.
Use voltage-drop testing.
15. Poor PCM or Engine Ground
A poor ground can interfere with:
- PCM driver operation
- Circuit monitoring
- Solenoid current
- Sensor feedback
Inspect:
- Battery negative cable
- Engine ground strap
- Body ground
- PCM grounds
- Ground eyelets
- Corroded mounting surfaces
Multiple unrelated circuit-low codes make a shared ground problem more likely.
16. Low Battery or Charging Voltage
A weak battery or charging problem may contribute to actuator circuit faults.
Check:
- Battery state of charge
- Cranking voltage
- Alternator output
- Battery-terminal condition
- Engine grounds
- Body grounds
Low system voltage is less likely if P0082 is the only stored code.
17. Low Engine Oil Level
Low oil usually does not create the electrical circuit-low signal directly.
However, the VVT system depends on proper oil level and pressure.
Low oil can cause:
- Slow camshaft response
- Solenoid sticking
- Cam phaser noise
- Additional timing codes
- Low oil pressure
Always check oil level before actively commanding the VVT system.
18. Dirty or Sludged Engine Oil
Contaminated oil may restrict:
- Solenoid spool movement
- Solenoid filter screen
- Cylinder-head oil passages
- Camshaft actuator movement
Dirty oil is more likely to cause timing-performance codes than P0082 alone.
It may still create poor VVT operation after the electrical problem is repaired.
19. Incorrect Oil Viscosity
Oil that is too thick or too thin may cause:
- Slow VVT response
- Poor cold-start operation
- Low hot-idle pressure
- Cam phaser noise
- Related timing codes
Use the manufacturer-specified:
- Oil viscosity
- Oil standard
- Filter type
20. Clogged Solenoid Screen
Some intake VVT solenoids contain a fine oil filter screen.
It may become restricted by:
- Sludge
- Varnish
- Metal particles
- Gasket material
- Excessive silicone sealant
A clogged screen is primarily a hydraulic fault, but contamination may coexist with an electrically shorted solenoid.
21. Incorrect Replacement Solenoid
A replacement solenoid may have:
- Coil resistance below specification
- Incorrect connector pinout
- Different oil passages
- Incompatible electrical characteristics
- Poor internal construction
A new component may still be:
- Incorrect
- Defective
- Counterfeit
- Cataloged for a different engine
New packaging does not make the resistance specification optional.
22. PCM Software Issue
PCM software may incorrectly:
- Evaluate the control circuit
- Command the solenoid
- Interpret driver feedback
- Set P0082 prematurely
Check for:
- Technical service bulletins
- Calibration updates
- Reprogramming procedures
- Revised diagnostic information
Software faults are less common than solenoid, wiring, and connector failures.
23. Failed PCM Driver
The PCM output driver may fail because of:
- Shorted solenoid coil
- Excessive current
- Control circuit shorted to voltage
- Water intrusion
- Internal module damage
Only suspect the PCM after confirming:
- Solenoid resistance
- Supply voltage
- Control-circuit isolation
- Wiring continuity
- Connector condition
- PCM power and ground
- Correct software level
Replacing the PCM before testing the two-wire solenoid circuit is a four-figure method of discovering that one wire is touching the cylinder head.
Is P0082 Serious?
P0082 is generally considered a moderate-severity code.
The engine may continue running, but the Bank 2 intake camshaft system may become:
- Disabled
- Fixed in a default position
- Incorrectly energized
- Unable to follow PCM commands
Possible consequences include:
- Reduced power
- Rough idle
- Poor fuel economy
- Increased emissions
- Hard starting
- Engine stalling
- Failed emissions inspection
The code becomes more serious if:
- Oil-pressure warning light is illuminated
- Engine oil is extremely low
- Engine rattles or knocks
- Vehicle stalls
- Misfires are severe
- Wiring becomes hot
- The fuse repeatedly blows
- Timing correlation codes are present
Can You Drive With P0082?
You may be able to drive a short distance if:
- Engine oil level is correct
- Oil-pressure warning light is off
- Engine runs reasonably smoothly
- Acceleration remains safe
- No severe timing noise is present
- Wiring is not overheating
Avoid continued driving if:
- Oil-pressure warning is illuminated
- Engine rattles
- Vehicle stalls repeatedly
- The Check Engine Light flashes
- Power is severely reduced
- Wiring smells burned
- A fuse repeatedly blows
- Engine will not start reliably
P0082 usually does not cause immediate internal engine damage by itself.
Continuing to drive with low oil pressure, severe timing noise, or overheated wiring is a separate and considerably more expensive decision.
How to Diagnose P0082
Step 1: Scan All Stored Codes
Check for:
- P0075
- P0076
- P0077
- P0081
- P0082
- P0083
- P0020
- P0021
- P0022
- Camshaft position codes
- Crankshaft position codes
- Oil-pressure codes
- Misfire codes
- System-voltage codes
Record:
- Freeze-frame data
- Pending codes
- Confirmed codes
- Permanent codes
- Engine RPM
- Battery voltage
- Oil temperature
- Solenoid command
- Desired camshaft angle
- Actual camshaft angle
Multiple circuit-low codes may indicate a shared power or ground problem.
Step 2: Confirm the Correct Definition
Verify that the scanner identifies P0082 as:
Intake Valve Control Solenoid Circuit Low Bank 2
The code should not be confused with:
- P0081 general circuit malfunction
- P0083 circuit high
- P0020 Bank 2 intake camshaft actuator circuit
- P0021 timing over-advanced
- P0022 timing over-retarded
Step 3: Confirm the Engine Has a Bank 2
An inline engine normally does not have Bank 2.
If P0082 appears on an inline engine, verify:
- Vehicle identification
- Scanner interpretation
- Manufacturer-specific code definition
- PCM calibration
- Installed engine configuration
Step 4: Identify Bank 2
Locate:
- Cylinder number 1
- Bank 1 cylinder head
- Opposite Bank 2 cylinder head
- Bank 2 intake camshaft
- Correct intake VVT solenoid
Do not confuse:
- Bank 2 and Bank 1
- Intake and exhaust solenoids
- VVT solenoid and camshaft position sensor
Step 5: Check Engine Oil Level
Park on level ground and verify:
- Oil level
- Oil condition
- Correct viscosity
- Signs of leakage
- Oil-pressure warning behavior
Correct low oil before performing active VVT tests.
Step 6: Inspect Oil Condition
Look for:
- Sludge
- Varnish
- Fuel dilution
- Coolant contamination
- Metal debris
- Incorrect viscosity
- Excessive service interval
Perform an oil and filter change if necessary, but continue electrical testing because P0082 is a circuit-low code.
Step 7: Locate the Bank 2 Intake Solenoid
The solenoid may be mounted:
- In the Bank 2 cylinder head
- Near the valve cover
- Near the timing cover
- At the front or rear of the cylinder head
- Beneath the intake manifold
- Beneath an engine cover
Use service information to identify the exact component.
Step 8: Inspect the Solenoid Connector
Check for:
- Connector not fully seated
- Broken locking tab
- Missing secondary lock
- Oil contamination
- Water intrusion
- Bent pins
- Corrosion
- Backed-out terminals
- Spread terminals
- Heat damage
Repair connector problems before replacing the solenoid.
Step 9: Inspect the Wiring Harness
Follow the wiring toward:
- Main engine harness
- Fuse box
- PCM
Look for:
- Melted insulation
- Chafing
- Pinched sections
- Contact with exhaust heat
- Contact with engine brackets
- Rodent damage
- Poor previous repairs
- Missing harness retainers
Focus on areas where the wiring crosses metal or hot components.
Step 10: Check Shared Fuses and Relays
Identify any fuse or relay supplying:
- Bank 1 intake solenoid
- Bank 2 intake solenoid
- Exhaust VVT solenoids
- Fuel injectors
- Other engine actuators
If the fuse is blown:
- Disconnect the Bank 2 solenoid.
- Measure solenoid resistance.
- Test the power wire for a short to ground.
- Inspect other components sharing the fuse.
- Repair the short.
- Install the correct fuse rating.
- Retest the system.
Never install a higher-amperage fuse.
That does not fix the short. It simply promotes the wiring harness to the role previously held by the fuse.
Step 11: Measure Solenoid Resistance
Disconnect the Bank 2 intake VVT solenoid and measure resistance across its terminals.
Compare the measurement with factory specifications.
Possible results include:
- Resistance below specification: shorted coil
- Near-zero resistance: severe internal short
- Infinite resistance: open coil
- Correct resistance: continue circuit testing
Do not use a generic resistance value from an unrelated engine.
Step 12: Compare Bank 1 and Bank 2 Solenoids
If the intake solenoids are identical, compare:
- Coil resistance
- Connector pinout
- Current draw
- Temperature
- Physical condition
A Bank 2 resistance reading substantially lower than Bank 1 may indicate an internally shorted solenoid.
Step 13: Test the Solenoid Against Its Housing
When permitted by manufacturer procedures, measure resistance between each terminal and the solenoid body.
Unexpected continuity may indicate:
- Internal short
- Insulation failure
- Contamination
- Coil contact with the housing
Step 14: Disconnect the Solenoid and Observe the Circuit
With the solenoid disconnected, monitor the circuit using the scan tool and electrical test equipment.
If the low condition changes to an open or high condition:
- The solenoid may be internally shorted
If the circuit remains low with the solenoid disconnected:
- The control wire may be shorted to ground
- Supply voltage may be missing
- Connector terminals may be bridged
- PCM driver may be faulty
Interpret the result using the vehicle’s wiring diagram.
Step 15: Verify Supply Voltage
With the ignition on, identify and test the power-supply terminal.
Expected voltage may be:
- Battery voltage
- Ignition voltage
- Relay-controlled voltage
- PCM-controlled voltage
If voltage is missing, inspect:
- Fuse
- Relay
- Supply wire
- Shared splice
- Fuse-box terminal
- Intermediate connector
Step 16: Load-Test the Supply Circuit
An unloaded digital multimeter can display normal voltage through a corroded or nearly broken connection.
Perform an approved loaded test across:
- Fuse
- Relay contacts
- Supply wire
- Shared splice
- Connector terminal
If voltage collapses under load, the circuit contains excessive resistance.
Step 17: Determine How the PCM Controls the Circuit
Use the wiring diagram to determine whether the PCM controls:
- Ground
- Power
- Pulse-width-modulated duty cycle
Use appropriate equipment such as:
- Digital multimeter
- Graphing meter
- Low-current test light
- Oscilloscope
Do not use a high-current incandescent test light on a PCM driver unless factory procedures specifically allow it.
Step 18: Test the Control Wire for a Short to Ground
Disconnect the solenoid and PCM as instructed.
Measure resistance between:
- Control wire
- Chassis ground
- Engine ground
Unexpected continuity may indicate a short.
Move the harness while testing because the wire may only touch ground in a particular position.
Step 19: Test for a Short Between Circuits
Check whether the control wire is contacting:
- Another VVT circuit
- Injector wiring
- Ignition wiring
- Sensor ground
- Heated oxygen sensor wiring
- Solenoid power feed
Melted wiring may fuse several circuits together inside an otherwise ordinary-looking harness.
Step 20: Check Circuit Continuity
Test both wires from the solenoid connector to their destinations.
Look for:
- Open circuit
- Excessive resistance
- Incorrect terminal location
- Corroded splice
- Weak repair
- Intermittent connection
Move the harness during testing.
Step 21: Check Connector Terminal Tension
Use a manufacturer-approved terminal test tool.
Inspect for:
- Spread terminal
- Weak grip
- Backed-out pin
- Broken retaining tang
- Incorrect replacement terminal
Avoid forcing oversized meter probes into the connector.
That can create a loose connection and turn a diagnostic session into an accidental connector repair.
Step 22: Perform Voltage-Drop Testing
With the circuit commanded on, measure voltage drop across:
- Power-supply wire
- Fuse
- Relay contacts
- Connector terminals
- PCM control wire
- PCM grounds
Excessive voltage drop indicates unwanted resistance.
Step 23: Command the Solenoid With a Scan Tool
Use a bidirectional scan tool when supported.
Monitor:
- Bank 2 intake-solenoid command
- Duty cycle
- Control-circuit voltage
- Current draw
- Desired Bank 2 intake camshaft angle
- Actual Bank 2 intake camshaft angle
- Engine idle quality
Possible results include:
- Excessive current: shorted solenoid or wiring
- Circuit voltage stuck low: grounded control wire or driver fault
- No supply voltage: fuse, relay, or supply-wire fault
- Electrical response without camshaft movement: hydraulic or mechanical problem
- Bank 1 responds while Bank 2 does not: Bank 2-specific fault
Step 24: Measure Solenoid Current
A low-current clamp may reveal:
- Excessive current: shorted coil
- Zero current: missing power or open circuit
- Unstable current: loose connection
- Current present when command is off: grounded control wire
Compare the result with:
- Manufacturer specifications
- Bank 1 intake solenoid
- Known-good waveform
Step 25: Examine the PWM Waveform
An oscilloscope can display:
- Duty cycle
- Voltage amplitude
- Driver switching
- Current ramp
- Circuit pull-down
- Driver shutdown
- Electrical noise
A waveform stuck near ground may indicate:
- Control wire shorted to ground
- Internally shorted solenoid
- Failed PCM driver
Step 26: Perform a Wiggle Test
Monitor circuit voltage and current while moving:
- Bank 2 solenoid connector
- Harness near the valve cover
- Wiring beneath the intake manifold
- Harness near exhaust components
- Fuse-box connectors
- PCM connector
- Previous repair areas
Watch for:
- Voltage changes
- Current spikes
- Code status changes
- Idle changes
- Camshaft response returning
Step 27: Inspect the Solenoid Mechanically
If electrical testing passes, remove the solenoid according to the repair procedure.
Inspect for:
- Sludge
- Varnish
- Metal debris
- Damaged filter screen
- Stuck spool valve
- Broken O-ring
- Silicone contamination
Mechanical restrictions generally produce timing-performance codes, but they may coexist with P0082.
Step 28: Compare Bank 1 and Bank 2 Camshaft Data
Monitor:
- Desired intake camshaft angle
- Actual intake camshaft angle
- VVT duty cycle
- Engine RPM
- Oil temperature
If Bank 1 responds correctly and Bank 2 remains fixed, suspect:
- Bank 2 solenoid
- Bank 2 wiring
- Bank 2 oil passage
- Bank 2 camshaft actuator
- PCM Bank 2 driver
Step 29: Swap Solenoids Only When Approved
If the Bank 1 and Bank 2 intake solenoids are confirmed identical, a controlled swap may help isolate the fault.
After swapping:
- Fault moves to Bank 1: solenoid likely faulty
- P0082 remains on Bank 2: wiring, connector, supply, or PCM circuit likely faulty
Do not swap intake and exhaust solenoids unless the manufacturer confirms they are interchangeable.
Step 30: Check PCM Power and Grounds
Before condemning the PCM, verify:
- Constant battery supply
- Ignition supply
- PCM grounds
- Connector condition
- Terminal tension
- Water intrusion
- Charging-system voltage
Poor PCM power or ground may create misleading driver-circuit faults.
Step 31: Check Technical Service Bulletins
Search factory information using:
- VIN
- Model year
- Engine code
- P0082
- Solenoid part number
- PCM calibration number
- Related trouble codes
Possible factory corrections may include:
- Updated solenoid
- Revised wiring harness
- Connector repair
- Harness relocation
- PCM software update
- Revised diagnostic procedure
Step 32: Evaluate the PCM Driver
Only consider PCM failure after confirming:
- Correct solenoid resistance
- Correct power supply
- No control-wire short to ground
- No short to voltage
- Correct wiring continuity
- Secure connector terminals
- Correct PCM powers and grounds
- Current software
If the PCM driver continues holding the circuit low after all external circuits test correctly, the PCM may require:
- Software update
- Module repair
- Replacement and programming
Step 33: Verify the Repair
After completing repairs:
- Clear all diagnostic trouble codes.
- Start the engine.
- Confirm the oil-pressure warning light turns off normally.
- Monitor the Bank 2 intake-solenoid command.
- Check circuit voltage and current.
- Compare desired and actual Bank 2 camshaft timing.
- Compare Bank 1 and Bank 2 operation.
- Verify normal idle quality.
- Road-test under varied engine speeds and loads.
- Complete the required drive cycle.
- Rescan for pending and confirmed codes.
- Confirm P0082 does not return.

Actual costs depend on:
- Vehicle design
- Solenoid accessibility
- Wiring location
- Labor rate
- Oil condition
- Additional timing faults
- Module-programming requirements
A shorted solenoid mounted at the front of the cylinder head may be straightforward.
A grounded Bank 2 control wire hidden beneath the intake manifold may require removing enough parts to make the electrical fault feel personally invested in remaining undiscovered.
Common Diagnostic Mistakes
Avoid these common P0082 diagnostic mistakes:
- Assuming an inline engine has Bank 2
- Misidentifying Bank 2
- Replacing the Bank 1 solenoid
- Confusing intake and exhaust solenoids
- Assuming “circuit low” means low engine oil
- Replacing the solenoid without measuring resistance
- Ignoring a blown fuse
- Replacing a fuse without finding the short
- Ignoring melted wiring near exhaust components
- Testing voltage without loading the circuit
- Checking only continuity
- Using generic solenoid resistance specifications
- Replacing the camshaft phaser before testing the circuit
- Replacing the PCM before isolating the wiring
- Assuming a new aftermarket solenoid must be good
- Failing to compare Bank 1 and Bank 2 data
- Failing to verify repairs with active scan-tool testing
P0082 is an electrical circuit-low code.
Replacing the timing chain because the engine has variable valve timing skips several cheaper diagnostic steps and may leave the original grounded wire completely unimpressed.

P0082 is a generic OBD-II code that may appear on vehicles with a Bank 2 intake variable valve timing system, including certain:
- Nissan vehicles
- Infiniti vehicles
- Hyundai vehicles
- Kia vehicles
- Toyota vehicles
- Lexus vehicles
- Ford vehicles
- Lincoln vehicles
- Chevrolet vehicles
- GMC vehicles
- Cadillac models
- Dodge vehicles

- Intake VVT solenoid
The exact wiring, resistance specifications, fault thresholds, and component locations vary by vehicle.
P0082 on Nissan and Infiniti Vehicles
Nissan and Infiniti may call the component the:
Intake Valve Timing Control Solenoid Valve
Possible causes include:
- Shorted Bank 2 intake timing solenoid
- Harness short to ground
- Damaged connector
- Missing solenoid voltage
- ECM driver failure
- Incorrect replacement solenoid
Possible inspection areas include:
- Bank 2 solenoid resistance
- Connector condition
- Harness near the cylinder head
- Shared actuator power supply
- Engine-oil level and condition
- ECM control circuit
If additional Bank 2 timing codes are present, inspect:
- Oil passage restrictions
- Camshaft actuator
- Timing chain
- Camshaft position sensor
- Oil pressure
P0082 on Hyundai and Kia Vehicles
Hyundai and Kia may refer to the component as:
- Intake oil control valve
- CVVT oil control valve
- Intake valve control solenoid
Common diagnostic checks include:
- Solenoid coil resistance
- Connector condition
- Control wire short to ground
- Supply voltage
- Shared actuator fuse
- PCM driver operation
- Engine-oil level
Circuit-low VVT codes on electronically controlled oil-control valves typically require checking for grounded wiring, shorted solenoid coils, power-supply faults, and PCM driver problems.
P0082 After Engine Repairs
If P0082 appears after:
- Valve-cover replacement
- Cylinder-head repair
- Timing-chain service
- Engine replacement
- Intake manifold removal
- Solenoid replacement
inspect for:
- Bank 2 connector attached incorrectly
- Harness pinched beneath a bracket
- Wiring trapped under the valve cover
- Ground strap omitted
- Replacement pigtail wired backward
- Incorrect solenoid installed
- PCM connector not fully seated
A code that appears immediately after repair work should first be investigated in the area that was disturbed.
The PCM can calculate camshaft position in fractions of a second. It remains unable to rescue a wire that was crushed beneath yesterday’s intake-manifold installation.
P0082 After a Blown Fuse
If a VVT or engine-actuator fuse is blown:
- Disconnect the Bank 2 intake solenoid.
- Measure solenoid resistance.
- Test the supply wire for a short to ground.
- Inspect other actuators sharing the fuse.
- Check wiring near hot components.
- Repair the fault.
- Install the correct fuse.
- Command the system while monitoring current.
Never substitute a larger fuse.
The original fuse was attempting to save the harness. Overruling it rarely improves the ending.
Can Dirty Oil Cause P0082?
Dirty oil can contribute to mechanical VVT problems, but P0082 specifically describes a low electrical circuit condition.
Dirty oil may cause:
- Solenoid spool sticking
- Restricted oil screen
- Slow camshaft response
- Cam phaser noise
- P0021 or P0022
It generally does not directly cause:
- Control wire short to ground
- Shorted electrical coil
- Blown fuse
- Missing solenoid voltage
Check the oil, but do not stop the electrical diagnosis because the oil looks overdue.
Can a Bad VVT Solenoid Cause P0082?
Yes.
A Bank 2 intake VVT solenoid can cause P0082 if its internal coil:
- Shorts between windings
- Draws excessive current
- Has resistance below specification
- Shorts to its housing
- Fails electrically when hot
Measure resistance and current rather than replacing the solenoid based solely on the code description.
Can a Bad Camshaft Position Sensor Cause P0082?
A camshaft position sensor is not a common direct cause of P0082.
The camshaft sensor reports position, while P0082 monitors the intake valve control solenoid circuit.
A failed camshaft sensor is more likely to set:
- Camshaft position sensor code
- Camshaft correlation code
- VVT performance code
- Starting or stalling complaint
Diagnose all stored codes together.
How to Prevent P0082
Reduce the likelihood of P0082 by:
- Maintaining the correct engine-oil level
- Using the correct oil viscosity
- Following recommended oil-change intervals
- Repairing oil leaks promptly
- Keeping solenoid connectors clean and dry
- Replacing damaged connector seals
- Reinstalling engine-harness clips
- Keeping wiring away from exhaust heat
- Inspecting wiring after engine repairs
- Using OEM-quality VVT solenoids
- Avoiding oversized electrical probes
- Repairing blown-fuse causes immediately
Frequently Asked Questions
What does P0082 mean?
P0082 means the PCM has detected an electrical signal below specification in the Bank 2 intake valve control solenoid circuit.
What is the full definition of P0082?
The generic definition is:
Intake Valve Control Solenoid Circuit Low Bank 2
Where is Bank 2?
Bank 2 is the side of the engine that does not contain cylinder number 1.
Its exact physical location depends on the engine design.
Does an inline engine have Bank 2?
Normally, no.
Inline engines have one cylinder bank. P0082 generally applies to engines with two banks.
What does circuit low mean?
Circuit low means the PCM sees voltage or electrical feedback below its expected range.
Common causes include:
- Short to ground
- Shorted solenoid coil
- Missing supply voltage
- Excessive current
- Failed PCM driver
Does circuit low mean the engine oil is low?
No.
The word “low” refers to the electrical circuit.
Low engine oil can cause additional VVT problems, but it is not the same condition.
What causes P0082 most often?
Common causes include:
- Internally shorted Bank 2 intake VVT solenoid
- Control wire shorted to ground
- Melted or chafed wiring
- Corroded connector
- Missing power supply
- Blown fuse
- PCM driver fault
Is P0082 serious?
P0082 is moderately serious.
The engine may continue running, but performance, fuel economy, idle quality, and emissions may be affected.
Can I drive with P0082?
Possibly for a short distance if:
- Oil pressure is normal
- The engine runs reasonably well
- No severe timing noise is present
- Wiring is not overheating
- Power loss is mild
Stop driving if the oil-pressure warning appears, the engine rattles, the Check Engine Light flashes, or the vehicle stalls.
Can P0082 cause rough idle?
Yes.
Incorrect Bank 2 intake camshaft timing may cause rough idle, surging, misfires, or stalling.
Can P0082 cause poor acceleration?
Yes.
The engine may lose torque and throttle response if the Bank 2 intake camshaft cannot be adjusted.
Can P0082 cause Bank 2 misfires?
Yes.
Incorrect intake camshaft timing can contribute to misfires on the affected bank.
Ignition, fuel, vacuum, and compression problems should also be tested.
Can P0082 blow a fuse?
Yes.
An internally shorted VVT solenoid or grounded power wire may blow a shared engine-actuator fuse.
Can dirty oil cause P0082?
Dirty oil can cause hydraulic VVT performance problems, but P0082 requires electrical testing because it identifies a circuit-low condition.
What is the difference between P0081 and P0082?
P0081 indicates a general Bank 2 intake valve control solenoid circuit malfunction.
P0082 specifically indicates a low circuit condition.
What is the difference between P0082 and P0083?
P0082 indicates voltage or circuit feedback below specification.
P0083 indicates a circuit signal above specification.
What is the difference between P0076 and P0082?
P0076 affects the Bank 1 intake valve control solenoid circuit.
P0082 affects the Bank 2 intake valve control solenoid circuit.
Can I test the VVT solenoid with a multimeter?
Yes.
Common tests include:
- Coil resistance
- Short to housing
- Supply voltage
- Control-wire short to ground
- Circuit continuity
- Voltage drop
Use vehicle-specific specifications.
Can I apply battery voltage directly to the solenoid?
Only when the manufacturer’s test procedure permits it.
Incorrect polarity, continuous voltage, or excessive current can damage the solenoid or control circuit.
Can I swap Bank 1 and Bank 2 solenoids?
Only when:
- Part numbers are identical
- The manufacturer permits it
- Intake and exhaust positions are correctly identified
- Components are clean and undamaged
A controlled swap may help determine whether the fault follows the solenoid.
Does a replacement VVT solenoid require programming?
Usually not.
The vehicle may require:
- Code clearing
- Drive cycle
- Camshaft relearn
- Oil service reset
- PCM adaptation
A replacement PCM requires programming.
How much does P0082 cost to repair?
A Bank 2 intake VVT solenoid replacement commonly costs approximately $150–$500.
Wiring, power-distribution, camshaft actuator, timing-chain, or PCM repairs may cost substantially more.
Final Thoughts
The P0082 code means the PCM has detected a low electrical condition in the Bank 2 intake valve control solenoid circuit.
The most common causes include:
- Internally shorted Bank 2 intake VVT solenoid
- PCM control wire shorted to ground
- Melted or chafed engine wiring
- Corroded connector terminals
- Missing supply voltage
- Blown fuse
- Failed relay
- PCM driver fault
Start diagnosis by:
- Confirming the engine has a Bank 2.
- Identifying Bank 2 correctly.
- Scanning for related trouble codes.
- Checking engine-oil level and condition.
- Inspecting the Bank 2 intake-solenoid connector.
- Examining the wiring for a short to ground.
- Measuring solenoid resistance.
- Checking shared fuses and relays.
- Verifying power-supply voltage.
- Testing the PCM control circuit.
- Comparing Bank 1 and Bank 2 data.
- Commanding the solenoid with a bidirectional scan tool.
- Evaluating the PCM only after the external circuit passes.
Do not interpret “circuit low” as proof that the engine simply needs additional oil.
The engine does need the correct oil, but P0082 is warning that the electrical side of the Bank 2 intake VVT system has fallen below specification.
The eventual repair may be a shorted solenoid, grounded wire, corroded connector, blown fuse, failed relay, or PCM driver problem.
Variable valve timing may involve computer-controlled duty cycles, hydraulic oil passages, camshaft phasers, and enough engineering terminology to make the repair sound expensive before the hood is opened.
Sometimes the entire system is defeated by one wire rubbing against a bracket until it discovers ground.
