Crankshaft Position Sensors play a huge part in your vehicle’s operation. This is usually a hall effect or magnetic sensor that informs engine position and speed to the ECU or Powertrain Control Unit. Based on this information, your onboard computer dictates combustion events. Should this sensor fail or encounter issues, is when your P0335 trouble code is triggered.
If your check engine light is turned on, and you pull a P0335 trouble code using a scan tool, this guide can help. With the right amount of research and testing, you can fix P0335 issues with just a bit of patience.
What Does P0335 Code Mean?
Within the OBDII error code vernacular, the P0335 check engine light translates to Crankshaft Position Sensor “A” Circuit Malfunction. Although some vehicles have multiple crankshaft sensors, chances are you have just one. In order to clear this check engine light, you will need to perform a variety of tests to see where the problem lies.
What does the crankshaft position sensor do?
This sensor reads the position of your crankshaft, and sends this data to your ECU. By measuring the exact rotational speed as well as the position of your crank, your vehicle can function. The Powertrain Control Unit or ECU will then use this data to control spark and fuel delivery.
If this signal is interrupted or the ECU sees a value that’s incorrect, a misfire can occur. When there is no signal from this sensor that’s when the P0335 check engine light is illuminated

Symptoms of a failed crankshaft position sensor
How can you tell if your crankshaft position sensor is bad? There are quite a few symptoms of this failure, a few of which you can find below.
Car won’t start – Hard to start car – Without the right signal, your ECU will refuse to deliver fuel or spark. When this happens, you need to fix P0335 issues before you can get your car back on the road.
Engine stalls – This can be a serious condition and one you shouldn’t drive your vehicle under. If your vehicle stalls, this can create dangerous problems, especially if you own an automatic or CVT transmission.
Engine misfires – Because your ECU doesn’t know exactly what your crank is up to, misfires can occur. These can cause damage to your engine, and can even lead to popping from your tailpipe or black soot and even smoke.
Check Engine Light – When your crankshaft sensor fails, the stored MIL status will trigger your check engine light. If this happens, don’t be discouraged but look for the right P0335 guide to clear check engine light problems.
Common Causes
Bad Camshaft Position Sensor – In some rare cases, bad camshaft sensors can contribute to the P0335 trouble code. This usually causes other MIL codes as well, so be mindful of that before checking your CAS.
Defective Crankshaft Position Sensor – One of the obvious culprits to this check engine light, replacing your CKP will fix this issue.
Bad wiring – Corroded wiring or a break in the vehicle wiring can cause problems with your crankshaft sensor signal.
