P0018

2017-10-10

Description:

  • The fault code P0018 indicates that there is a timing correlation issue between the crankshaft and camshaft sensors in bank 2, sensor A. This may cause the engine to run poorly or not start at all.

Possible Symptoms:

  • Check Engine Light (CEL) illuminated

  • Engine misfires

  • Rough running engine

  • Decreased engine performance or power

  • Poor fuel efficiency

Possible Causes:

  • Incorrect camshaft timing

  • Faulty camshaft position sensor

  • Faulty crankshaft position sensor

  • Timing chain or belt issues

  • Engine oil contamination or low oil level

  • Faulty engine control module (ECM)

Related Parts:

  • Crankshaft Position Sensor: The crankshaft position sensor monitors the position of the crankshaft to regulate fuel injection. Problems lead to engine misfire and engine stalling

  • 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:

  • Verify and correct the camshaft timing if it is off

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

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

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

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

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