A vehicle knock sensor is a sensor screwed into the engine's block or cylinder head. It is used to measure engine jitter and to adjust ignition advance Angle when the engine produces knock.
The sensor creates a voltage signal based on the vibrations caused by erratic air/fuel mixture combustion; the engine control module uses this signal to adjust the ignition timing and air/fuel mixture.
