What Does a Knock Sensor Do?

The knock sensor monitors engine vibrations and detects abnormal combustion events such as engine knock or detonation. 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 engine to run at optimal timing under normal conditions while protecting against harmful detonation. A properly functioning knock sensor is essential for maximum performance, fuel efficiency, and engine longevity.
