CAMSHAFT POSITION SENSOR

Removal (3.1L &  3.4L)

1. The Camshaft Position (CMP) sensor is located at top rear of cylinder block. See Fig. 28. Turn ignition off. Remove the accessory drive belt from the power steering pump.
2. Remove the power steering pump. See appropriate POWER RACK &  PINION article in STEERING. Disconnect the CMP sensor electrical connector. Remove the attaching bolt. Remove the CMP sensor.
Inspect the sensor "O" ring for wear,  cracks,  or leakage if the sensor is not being replaced.

Installation

NOTE: Inspect the CMP sensor "O" ring for wear or damage. If a problem is found,  replace the "O"ring.

Be carefulon removal and try to twist it out as this can be brittle and break
