    NOTE:

    If a crankshaft or camshaft position sensor DTC is set, the Camshaft Position Actuator output control will not function.

    • The CMP Acutator Solenoid Ckt Open Test Status
    • The CMP Actuator Solenoid Ckt Short To Volts Test Status

      Each parameter should display OK or Not Run

  3. Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.
