The Knock Sensor is a BOSCH Porsche 928 engine management component designed to detect abnormal combustion events, commonly known as engine knock or detonation. Mounted directly to the engine block, the sensor monitors engine vibrations and sends signals to the engine control unit (ECU), allowing ignition timing to be adjusted instantly to protect the engine from damage while maintaining optimum performance.
