Knock Sensor (KS)

KS measures vibrations (pre-ignition) and converts them into an electrical signal. The signal is sent to the Knock Control Unit (KCU) where it is filtered and sent to the ECA. The ECA monitors signal from KCU and adjusts ignition timing if pre-ignition occurs. The KS is threaded into the engine block, near the oil pressure switch.
