Knock Sensor (KS)

On V8 engines, knock sensors are located at the center of the cylinder block on the inboard side of each cylinder bank. On V6 engines, right bank knock sensor is located on the side of engine block, near starter. The left bank knock sensor is located on the inboard side of cylinder bank. On all engines, sensors are piezo-electric devices that provide inputs to the ECM or PCM to detect and locate detonation during combustion.
