OBD II Fault Code

  • OBD II P0022

Fault Code Definition

  • "A" Camshaft Position - Timing Over-Retarded

What does this mean? The engine control module (PCM) uses a signal from the camshaft position sensor to determine the the proper time to fire the fuel injectors and ignite the spark plugs. The PCM compares this signal to the signal from the crankshaft to determine if the engine is timed properly. Newer vehicles use a variable timing system to adjust when intake and exhaust valves open and close to increase fuel efficiency and performance. If the Camshaft is not in the proper position relative to the crankshaft, the PCM will set code P0022.

Symptoms

  • Decreased engine performance
  • Increased fuel consumption

Common Problems That Trigger the P0022 Code

  • Camshaft variable timing solenoid failure
  • Engine oil level is too low
  • The engine is not timing correctly
  • The engine oil does not meet the manufacturer's requirements
  • Variable valve timing actuator failure
  • Worn timing chain
