The CKP sensor is located at the front lower left corner of the engine. Begin by disconnecting the cable from the negative battery terminal. Next, raise the vehicle and place it securely on jackstands. Remove the engine under-cover. For V6 models, take out the alternator and remove the bolt that secures the air conditioning suction line at the front of the engine, then disconnect the electrical connector from the air conditioning compressor and unbolt the compressor. Disconnect the CKP sensor electrical connector by sliding the white plastic lock to the rear and pulling off the connector. To detach the CKP sensor from the engine, remove the sensor mounting bolt. For V8 models, the CKP sensor is located on the left underside of the oil pump at the front of the engine; to remove it, disconnect the electrical connector and remove the sensor retaining bolt. Finally, remove the CKP sensor retaining bolt and ensure that installation is the reverse of removal, tightening the CKP sensor retaining bolt securely.
