Camshaft Position Actuator Solenoid Valve Inspection
Important: Do not use the camshaft position (CMP) actuator solenoid valve again. Install a NEW valve during assembly. The inspection
procedure below is provided for off-vehicle diagnostic purposes only.
1. Inspect the CMP valve for the following conditions:
*
Dirt, debris, or restrictions within the oil passages (1)
*
Damaged threads (2)
If the threads of the valve are damaged, also inspect the threads in the front of the camshaft for damage.
*
Dirt, debris, or restrictions within the oil inlet check valve (3)
If debris is detected, the engine assembly should be inspected to determine the source of contamination.
