Mercury AA5Z-6C315-A Sensor - Crankshaft Position

You can Select Your Vehicle to check if AA5Z-6C315-A fits your vehicle.

Disconnect the electrical connector from the air conditioning compressor clutch and unbolt the air conditioning compressor, setting it aside to provide access to the CKP sensor.

Firstly, disconnect the cable from the negative battery terminal. Then, loosen the right front wheel lug nuts, raise the front of the vehicle, and place it securely on jackstands.

Installation is the reverse of removal. Tighten the mounting bolt to the torque specification.

During installation, install the CKP sensor without tightening the mounting bolts. If using a new CKP sensor, align it with the special alignment jig provided and tighten the bolts securely before removing the jig. If using the old CKP sensor, align it with the timing plate by counting 20 teeth counterclockwise from the blank spot and drawing a straight line from the center of the 20th tooth through the center of the crankshaft pulley. Position the centerline of the CKP sensor with the line and tighten the bolts securely.

If replacing the CKP sensor triggers a DTC, and you have a generic scan tool that can clear codes, erase the code and check if it reappears. If the code returns, take the vehicle to a dealer service department to perform a Misfire Monitor Neutral Profile Correction procedure with a factory scan tool.

Disconnect the cable from the negative battery terminal.
