What is a knock sensor?


A knock sensor is a device for detecting knock or detonation.

Knock sensors come in various styles. The simplest is just a microphone element that picks up engine vibrations and noise and sends the signals to the onboard ECU. This is the type of sensor used on the DSM cars. Other sensors might do some signal processing or filtering inside the sensor before generating the output signal.
