The knock sensor detects abnormal engine knocking. The sensor is mounted on the engine block near the cylinders. The sensor produces an AC output voltage that increases as knocking increases. This signal is sent to the engine control module (ECM). The ECM adjusts the ignition timing to reduce knocking.
