Circuit/System Verification

WARNING: This page is about a different variant/trim than selected.
    NOTE:
    • The engine oil level and the oil pressure are critical to the correct operation of the camshaft position actuator system. Verify that the engine has the correct oil level and the correct oil pressure before continuing with this diagnostic.
    • The engine oil condition has a major impact on the camshaft actuator system. Debris in the oil can interfere with the camshaft position actuator solenoid and the mechanical camshaft actuator operation. Inspect for dirty or degraded crankcase oil. The engine may require an oil change. Inquire with the customer when the last oil change was performed. You may also monitor the scan tool Engine Oil Life Remaining parameter. Advise the customer an oil change may be required.
  1. Verify the correct engine oil pressure. Refer to Oil Pressure Diagnosis and Testing
    2. NOTE:

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

  2. Ignition ON.
  3. Verify that DTC P0010, P0013, P0016, P0017, P0335, P0336, P0340, P0341, P0365, P0366, P2088, P2089, P2090 or P2091 is not set.
    • If none of the DTCs are set 
    4. NOTE:

    If there is no condition with the camshaft position actuator, the engine may stall when commanding the actuator to 20 degrees.

  4. Engine idling, command the appropriate Camshaft Position Actuator from 0 degrees to 20 degrees and back to zero while observing the appropriate scan tool Intake/Exhaust Camshaft Position Variance parameters. Once stabilized, the Intake/Exhaust Camshaft Position Variance should be less than 2 degrees in each of the commanded states.
    • If not within the specified range 

      Refer to Circuit/System Testing below.

    • If within the specified range 
  5. 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.
  6. Verify a DTC does not set.
    • If any DTC sets 

      Refer to Circuit/System Testing below.

    • If a DTCs does not set 
  7. All OK.
