OBD II Fault Code

    Fault Code Definition

    • "A" Camshaft Position - Timing Over-Advanced or System

    What does this mean? Newer vehicles use a variable timing system to adjust the timing of the intake and exhaust valves in an effort to increase fuel efficiency and performance. The engine control module (PCM) uses a Camshaft Position Actuator to adjust the camshaft accordingly. If the Camshaft does not respond as the PCM requests, the PCM will set code P0011.


    • Decreased engine performance
    • Increased fuel consumption

    Common Problems That Trigger the P0011 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
