Important: This engine is equipped with 2 knock sensors. This service procedure applies to both the right and left knock sensors

1. Raise the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.



2. Disconnect the knock sensor (KS) electrical connector.
3. Remove the KS bolt.
4. Remove the KS.

Important:  DO NOT apply thread locker to the sensor threads. The sensor threads are coated at the factory and applying additional thread locker affects the sensor's ability to detect detonation.

1. Install the KS to engine block.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

2. Install the KS bolt.
