What Does a Knock Sensor Do?

The Knock Sensor (also known as a detonation sensor) monitors engine vibrations to detect abnormal combustion events such as knock or pre-ignition. When knock is detected, the sensor sends a signal to the engine control unit (ECU), which retards the ignition timing to prevent engine damage. This allows the ECU to run the engine at optimal timing for maximum performance while protecting against detonation damage. Without a properly functioning knock sensor, your engine is at risk of serious damage from uncontrolled detonation.
