What Does the P0014 Code Mean?
If your Check Engine Light is on and your OBD-II scanner displays P0014, your vehicle’s Engine Control Module (ECM) has detected that the Bank 1 exhaust camshaft (“B” camshaft) is more advanced than the ECM commanded.
Modern engines use Variable Valve Timing (VVT) or Variable Camshaft Timing (VCT) systems to adjust camshaft timing based on engine speed, throttle position, and load. This improves:
- Horsepower
- Torque
- Fuel economy
- Emissions
When the ECM commands the exhaust camshaft to return to a specific position and it remains too far advanced, it stores Diagnostic Trouble Code (DTC) P0014.
P0014 is extremely common on vehicles from Chevrolet, GMC, Buick, Cadillac, Ford, Hyundai, Kia, BMW, Nissan, Subaru, Volkswagen, Audi, and many others equipped with variable valve timing.
Quick Answer
| Item | Information |
|---|---|
| Code | P0014 |
| Description | “B” Camshaft Position Timing Over-Advanced (Bank 1) |
| Severity | ⭐⭐⭐⭐☆ High |
| Safe to Drive? | Short distances only |
| Common Causes | Dirty oil, VVT solenoid, timing chain wear |
| Estimated Repair Cost | $60–$3,500+ |
What Does “B Camshaft” Mean?
Manufacturers identify camshafts as:
- A Camshaft = Intake Camshaft
- B Camshaft = Exhaust Camshaft
Bank 1 is the side of the engine containing Cylinder #1.
P0014 means:
Bank 1 Exhaust Camshaft Timing is More Advanced Than Expected
The ECM attempted to retard the camshaft, but the timing remained too far advanced.
How Does Variable Valve Timing (VVT) Work?
Your engine uses:
- Camshaft actuator (phaser)
- Oil control valve (VVT solenoid)
- Engine oil pressure
- Camshaft position sensors
- Crankshaft position sensor
The ECM directs oil pressure into the cam phaser to rotate the camshaft slightly.
When oil flow, sensors, or mechanical components fail, incorrect cam timing results.
Symptoms of a P0014 Code
Common symptoms include:
- Check Engine Light
- Rough idle
- Engine hesitation
- Loss of power
- Poor acceleration
- Reduced fuel economy
- Hard starting
- Engine rattling
- Stalling
- Increased emissions
Some vehicles may also enter limp mode to protect the engine.
How Serious Is P0014?
Severity: ⭐⭐⭐⭐☆ (High)
P0014 should not be ignored.
Continued driving may lead to:
- Timing chain damage
- Cam phaser failure
- Valve timing problems
- Poor engine performance
- Internal engine damage (rare but possible)
If accompanied by loud timing chain noise, repairs should be made immediately.
Can You Drive With P0014?
Only Temporarily
If:
- Engine runs normally
- No loud timing chain noise
- No severe power loss
You may drive a short distance for repairs.
Stop Driving Immediately If
- Engine rattles loudly
- Vehicle enters limp mode
- Severe power loss develops
- Engine stalls repeatedly
- Oil pressure warning appears

Step-by-Step Diagnosis
Step 1: Check Engine Oil
Before replacing any parts:
Verify:
- Oil level
- Oil condition
- Correct viscosity
- Oil change interval
Dirty or incorrect oil is one of the leading causes of P0014.
Step 2: Scan for Additional Codes
Look for:
- P0010
- P0011
- P0013
- P0016
- P0017
- P0021
- P0340
Multiple timing-related codes often indicate a larger problem.
Step 3: Inspect the VVT Solenoid
Remove the oil control valve.
Inspect for:
- Sludge buildup
- Metal debris
- Clogged screens
Test resistance using a multimeter according to factory specifications.
Step 4: Monitor Camshaft Data
Using live scan data, compare:
- Commanded cam angle
- Actual cam angle
Large differences indicate:
- Cam phaser problems
- Timing chain wear
- Oil pressure issues
Step 5: Verify Oil Pressure
Low oil pressure can prevent the VVT system from operating correctly.
Check oil pressure at:
- Idle
- 2,500 RPM
Compare readings with factory specifications.
Step 6: Inspect the Timing Chain
Listen for:
- Startup rattle
- Chain slap
- Timing cover noise
Excessive timing chain stretch commonly triggers P0014 on high-mileage engines.
Step 7: Inspect the Cam Phaser
If everything else checks out, inspect the cam phaser.
A sticking actuator may fail to return to its commanded position.
Common Diagnostic Mistakes
Avoid these costly errors:
- Replacing camshaft sensors first
- Ignoring dirty engine oil
- Skipping oil pressure testing
- Replacing the timing chain without diagnosis
- Ignoring startup rattles
- Overlooking clogged VVT solenoids
Many P0014 repairs are solved with proper oil maintenance and VVT servicing.

Frequently Asked Questions
Can dirty oil cause P0014?
Yes.
Dirty, degraded, or incorrect engine oil is one of the leading causes because the VVT system relies on clean oil pressure to operate.
Can I drive with P0014?
You can usually drive a short distance if the engine is running normally, but prolonged driving may lead to timing chain or cam phaser damage.
Does P0014 mean my timing chain is bad?
Not always.
While timing chain stretch is a common cause, many vehicles only require an oil change or VVT solenoid replacement.
Can a bad VVT solenoid trigger P0014?
Absolutely.
A sticking or clogged oil control valve is one of the most common causes of this code.
Will changing the oil fix P0014?
In many cases—especially if the oil is overdue or the wrong viscosity was used—an oil and filter change can resolve the problem.
Final Thoughts
The P0014 “B” Camshaft Position Timing Over-Advanced (Bank 1) code often sounds intimidating, but many repairs are simpler than expected. Because modern variable valve timing systems depend heavily on clean engine oil and proper oil pressure, neglected maintenance is one of the biggest contributors to this code.
Before replacing expensive components like timing chains or cam phasers, inspect the oil condition, verify oil pressure, and test the VVT solenoid. A methodical diagnosis can save hundreds—or even thousands—of dollars while restoring proper engine performance and preventing more serious timing-related failures.
