P0335: Crankshaft Position Sensor A Circuit Issues Decoded

An integral part of every vehicle’s electrical system, the crankshaft position sensor tracks the exact location of the crankshaft and the engine’s rotational speed (RPM). This sensor is essential for your vehicle’s starting system.

What does error code P0335 mean?

A generic diagnostic trouble code c) indicates a problem with the crankshaft position sensor. When the engine control module is unable to identify the crankshaft position sensor, it will throw this error code.

The sensors that measure the position of the crankshaft send information about the engine’s rotational speed to the vehicle’s computer. In order to ensure a smooth combustion process, the ECM utilizes this data to decide when to dispatch the air-fuel mixture and when to ignite the spark plugs.

At the first sign of trouble, the PCM will alert the driver by illuminating the dashboard with an engine warning light. Typically, the vehicle’s computer will enter limp mode, which disables certain functions and reduces engine speed.

What Causes error code P0335?

A P0335 code could be thrown by the engine control unit due to a few different issues. Be on the lookout for the following signs.

  • Broken or lousy reluctor ring
  • Bad wiring harness or loose connections
  • A malfunctioning crankshaft position sensor
  • Misfiring engine
  • Lousy PCM
  • Lousy or broken timing chain or belt

How serious error code P0335 is?

Serious electrical or mechanical issues with the engine are indicated by the P0335 code on Toyota and other vehicle types. Stop driving the vehicle until you find out what’s causing the drivability problems and fix it.

It is possible for the engine to die in certain vehicles if it loses power while driving. This is the moment where the car might just stop starting. It is important to conduct a thorough diagnosis in order to identify and resolve the underlying reason.

  • Repairing or replacing the wiring harness
  • Fixing connector issues
  • Replacing malfunctioning crankshaft position sensor
  • Replacing lousy Engine control unit
  • Replacing signal plate
  • Replacing broken timing belt and fixing any mechanical damage caused

Conclusion

A diagnostic error code of P0335 indicates a serious problem, thus you should not ignore it. Problems with the timing belt or chain, as well as more minor ones like weak connections, can lead to this.

When the timing belt or chain is at fault, continuing to drive with a P0335 code will lead to disastrous consequences. The timing is irrelevant.
