Circuit/System Verification
- Ignition ON, clear the DTC information with a scan tool.
- Start the engine. Verify there is no abnormal engine noise during start up. Observe the DTC information with a scan tool. DTC P1011, P1012, P1013, or P1014 should not set.
- If there is an abnormal engine noise, or a DTC set, replace the appropriate CMP actuator.
- 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.
NOTE:
The engine oil level and the oil pressure are critical to the correct operation of the camshaft position (CMP) actuator system. Verify that the engine has the correct oil level and the correct oil pressure before continuing with this diagnostic. Refer to Fluid and Lubricant Recommendations
and OIL PRESSURE DIAGNOSIS AND TESTING
for more information.
