Knock Sensor: Installation

WARNING: This page is about a different car, the 2002 Pontiac Grand Prix, 2002 Chevrolet Monte Carlo, 2002 Chevrolet Impala, 2002 Buick Regal, and 2002 Buick Century. However, it is still accessible from the selected car via links, so may be relevant.
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.
