OBD II Fault Code

  • OBD II P0024

    Fault Code Definition

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

    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. Newer vehicles use a variable timing system to adjust the timing of the camshaft in relation to the crankshaft to increase fuel efficiency and performance. If the Camshaft is not in the proper position relative to the crankshaft, the PCM will set code P0024.


    • Decreased engine performance
    • Increased fuel consumption

    Common Problems That Trigger the P0024 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
