Knock Sensor: Installation

NOTE: Do not apply thread sealant to the sensor threads. The sensor threads are coated at the factory and applying additional sealant affects the sensor's ability to detect detonation.

Install the knock sensor into the engine block. Tighten the knock sensor to specification. See TORQUE SPECIFICATIONS  . Connect the knock sensor wiring harness connector to the knock sensor. Lower the vehicle.
