REMOVAL

The Crankshaft Position (CKP) sensor is located at the right-rear side of the engine cylinder block (Fig.

28). It is positioned and bolted into a machined hole in the engine block.

(1) Disconnect CKP electrical connector at sensor.

(2) Remove CKP mounting bolt (Fig. 28).

(3) Carefully pry sensor from cylinder block in a rocking action with two small screwdrivers.

(4) Remove sensor from vehicle.

(5) Check condition of sensor o-ring.

INSTALLATION

(1) Clean out machined hole in engine block.

(2) Apply a small amount of engine oil to sensor o-ring.
