Knock Sensor - Sierra Marine Engine Parts - 18-7677 (118-7677)

A knock sensor is a crucial part of the engine block, intake manifold, or cylinder head that senses vibrations in the event of a knocked engine. The knock sensor delays the timing when it detects detonation and preignition. It causes the trigger to the engine control correcting the knock hence preventing potential harm to the engine and abnormal combustion.
