Circuit/System Verification

NOTE: The engine oil level and the oil pressure are critical to the correct operation of the 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.

Start the engine. Verify there is no abnormal engine noise during start up.
