What Does a Knock Sensor Do?

The Knock Sensor detects abnormal combustion (engine knock or detonation) by monitoring vibrations in the engine block. When knock is detected, it sends a signal to the engine control unit (ECU), which retards ignition timing to prevent engine damage. This allows the ECU to run the engine at optimal timing for maximum performance while protecting against destructive detonation. A properly functioning knock sensor is essential for engine longevity, performance, and fuel efficiency.
