A knock sensor is located on the intake manifold, cylinder, or engine block. The purpose of the knock sensor is to sense unusual pulsations caused by the engine knock or detonation.
When you replace the knock sensor please be careful the grime will fall into the cylinders when you pull the intake manifold off.
