Knock Sensor: Description and Operation
Knock Sensor
This sensor is mounted on the engine block and monitors ignition knock (Detonation). This signal is sent to the ECU which in turn, retards the ignition
timing until detonation ceases. This control prevents internal damage to engine valves and pistons. The Knock Sensor inputs the ECU through terminal
KNK.
