The first step for repairing or servicing the Camshaft Position Sensor starts with disconnecting the negative
Battery Cable then removing the engine cover. During service begin by disconnecting
Spark Plug Wires along with the ignition coil wire from
Distributor and then disconnect the cmp sensor harness connector. First disconnect the Distributor cap screws along with the Distributor cap before proceeding to separate the rotor screws and the rotor. The alignment of the square slot on the reluctor wheel with the cmp sensor allows the removal of cmp sensor fasteners and sensor retrieval. During the replacement operation utilize fresh screws modified with a thread locking compound which can be obtained through gm p/n 10475922 for Distributor cap screws and gm p/n 10475924 for rotor screws packed in sets of ten screws each. Transport the cmp sensor through the reluctor wheel slot by aligning its square slot with the sensor then bolt the new mounting screws and tighten them to 1.6-2.8 n.m (14-25 lb in). The proper rotor alignment depends on maintaining the rotor locating tabs in position before screwing the rotor onto the reluctor wheel with new screws while tightening them to 1.5-2.4 n.m (13-22 lb in). Position the Distributor cap and secure it by using new Distributor cap screws which must be tightened between 1.8-3.0 n.m (16-26 lb in). To complete the process install the engine cover along with reconnecting the negative Battery Cable after connecting the cmp sensor harness connector and reconnecting the Spark Plug Wires and ignition coil wire.
