2009 Chevrolet Tahoe Camshaft Position Sensor

You need to inspect the CMP O-ring seal for cuts or damage. If the seal is not damaged, it may be reused. You need to lubricate the O-ring seal with clean engine oil, install the O-ring seal onto the sensor, the CMP sensor to the front cover and the CMP sensor wire harness, connect the CMP sensor wire harness electrical connector, ensure that the retainer fully engages the CMP sensor, install the 2 rear CMP sensor wire harness bolts, tighten the CMP sensor wire harness bolt using a box wrench, connect the CMP sensor wire harness electrical connector to the CMP actuator magnet and the engine wiring harness electrical connector to the CMP sensor wire harness and install the engine shield.

You need to remove the engine shield, disconnect the engine wiring harness electrical connector from the CMP sensor wire harness and the CMP sensor wire harness electrical connector from the CMP actuator magnet, loosen the CMP sensor wire harness bolt 2 turns using a box wrench, remove the 2 remaining CMP sensor wire harness bolts, use a small flat-bladed tool to disengage the CMP sensor wire harness electrical connector retainer from the CMP sensor and remove the CMP sensor wire harness and the CMP sensor and O-ring seal.
