Dry the components with compressed air.
Inspect the CMP actuator for a broken spring (1).
Inspect the CMP actuator for the following conditions:

1. Improper positioning of the CMP reluctor wheel (2). The CMP actuator return spring should reposition the CMP reluctor wheel to the PARK position. Inspect for proper alignment of the mark on the face of the CMP sprocket (1) with the flat edge of the reluctor wheel. If the CMP reluctor wheel is not properly positioned, the internal components of the actuator are sticking or the return spring is broken and the CMP actuator should be replaced as an assembly.
2. Nicked or damaged edges on the CMP reluctor wheel (2)
3. Damaged timing CMP sprocket teeth
Inspect the camshaft position actuator for dirt, debris, or restrictions within the oil passages (1, 2).

NOTE:
- The inspection procedure is provided for diagnostic purposes only.
- Do not use the camshaft position actuator solenoid valve again. Install a NEW valve during assembly.
Inspect the camshaft position actuator solenoid valve for the following conditions:

1. Dirt, debris, or restrictions within the oil passages (1)
2. Damaged threads (2)
  If the threads of the valve are damaged, also inspect the threads in the front of the camshaft for damage.
3. Dirt, debris, or restrictions within the oil inlet (3)
  If debris is detected, the engine assembly should be inspected to determine the source of contamination.
Inspect for a sticking valve spool or broken valve spool spring.

Depress the valve spool into the housing. The valve should move freely with no binding or sticking and minimal resistance inward. When released, the valve spring should return the spool to the proper extended position (1) of 6.52 - 6.92 mm (0.257 - 0.272 in).
