P0020

2017-10-10

Description:

  • The fault code P0020 indicates that there is an issue with the circuit that controls the camshaft position actuator for bank 2. This may cause the engine to run poorly, idle roughly, or not start at all.

Possible Symptoms:

  • Check Engine Light (CEL) illuminated

  • Rough idling or stalling

  • Decreased engine performance or power

  • Engine misfires

  • Poor fuel efficiency

Possible Causes:

  • Faulty camshaft position actuator solenoid

  • issues in the camshaft position actuator circuit, such as open or short circuits

  • Faulty camshaft position sensor

  • Engine oil contamination or low oil level

  • Timing chain or belt issues

  • Failed 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 actuator solenoid, if necessary

  • Check and repair any wiring issues in the camshaft position actuator circuit, such as open or short circuits

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

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

  • Inspect and repair any timing chain or belt issues

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