Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

1. Disconnect the negative battery cable.
2. Raise the vehicle.
3. Remove the knock sensor wiring harness connector from knock sensor.
4. Remove the knock sensor from engine block.

Important: Do Not apply thread sealant to sensor threads. The sensor is coated at factory and applying additional sealant will affect the sensor's ability to detect detonation.

1. Install the knock sensor into engine block.
2. Install the knock sensor wiring harness connector to the knock sensor.
3. Lower the vehicle.
4. Connect the negative battery cable.
