Camshaft Position Sensor: Testing and Inspection

2011 Chevrolet Silverado 1500 4WD V8-6.2LSECTION Testing and Inspection



Camshaft Position Actuator Solenoid Valve Inspection (On-Vehicle)





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 on-vehicle diagnostic purposes only.


1. With the CMP magnet removed, inspect for a sticking valve spool or broken valve spool spring.
2. 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 6.08-6.12 mm (0.239-0.241 in).
