GMC Sierra 1500 Replacement Knock Sensor Information


The GMC Sierra 1500's knock sensor is used to detect any pinging or knocking in the engine. It can be found attached to the engine cylinder head or block near the rear of the vehicle. The sensor sends a signal to the PCM/ECM that controls the timing of the engine. Your vehicle will commonly have a knock sensor for every engine bank. Knocks and pings can happen frequently when the vehicle is operating at higher temperature and/or using low grade fuel. Any vibrations caused by knocks in the vehicle are recognized by the sensor, which then emits a milli-voltage that is received by the car's computer, causing it to slow the timing of the engine.

Failing to replace a faulty knock sensor in your GMC Sierra 1500 can result in damage to the engine. PartsGeek.com has knock sensors for the GMC Sierra 1500 so that you can restore your car to working condition.
