OBD II Fault Code

  • OBD II P003D

    Fault Code Definition

    • "A" Camshaft Profile Control Stuck On

    What does this mean? Newer engines have valves that are electro-hydraulically controlled instead of being driven by a timing belt or chain. This improves fuel efficiency and engine performance. When the engine control module (PCM) detects that the valves are not being operated as desired, it will set code P003D.

    Symptoms

    • Decreased engine performance
    • Increased fuel consumption

    Common Problems That Trigger the P003D Code

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