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.\u003c\/p\u003e\n\u003ch3\u003eWhy Choose Genuine GM Knock Sensors?\u003c\/h3\u003e\n\u003cp\u003eGenuine GM knock sensors are designed to meet or exceed original equipment specifications, ensuring accurate knock detection, long-lasting reliability, and optimal engine protection.
