Description:

  • The fault code indicates that there is an issue with the timing of the camshaft position sensor for bank 2, specifically that it is over-retarded. This can negatively affect the engine's performance, including poor acceleration and a reduction in power.

Possible Symptoms:

  • Check Engine Light illuminated

  • Rough idling or stalling

  • Decreased engine performance or power

  • Engine misfires

  • Poor fuel efficiency

Possible Causes:

  • Faulty camshaft position sensor

  • Engine oil contamination (Thick oil)

  • low oil level

  • Oil control solenoid to the bank2 camshaft is clogged

  • Faulty camshaft timing actuator (Phaser) solenoid

  • Incorrect camshaft timing due to timing chain or belt issues

  • Faulty engine control module (ECM)

Related Parts:

  • Camshaft Position Sensor: The camshaft position sensor monitors the position of the camshaft to regulate fuel injection. Problems lead to stalling or car failing to start.

Possible Solutions:

  • Test and replace the faulty camshaft position sensor, if necessary

  • Ensure the engine oil is at the correct level and free from contamination

  • Test and replace the faulty camshaft timing actuator solenoid (Phaser), if necessary

  • Inspect and repair any timing chain or belt issues that may be causing incorrect camshaft timing

  • Test and replace the engine control module (ECM) if it is determined to be faulty
