NOTE:

If reinstalling the sensor (1), check the sensor O-ring (2) for damage and replace if necessary. Lubricate the O-ring with clean engine oil before installing the sensor. Clean off the old spacer (3) on the sensor face. A NEW SPACER (3) must be attached to the face before installation.

CAUTION:

A NEW SPACER must be attached to the face of the sensor before installation. The spacer sets the correct clearance between the sensor and the camshaft gear. An improperly positioned sensor can result in sensor damage, a faulty signal or no signal at all.

Install the camshaft position (CMP) sensor in the chain case cover and rotate into position.
