The MEAT & DORIA 87767 Detonation Sensor is designed to monitor your engine's combustion process. It identifies abnormal combustion events, commonly known as knocking or detonation, which can cause significant engine damage if left unaddressed. By accurately detecting these vibrations, the sensor sends a signal to the engine control unit (ECU). The ECU then adjusts ignition timing to prevent further knocking, thereby protecting the engine and maintaining its optimal performance. This component is crucial for the longevity and efficiency of your vehicle's powertrain. This sensor is manufactured to meet stringent quality standards, ensuring reliable and consistent performance. Its robust construction is built to withstand the demanding conditions found within the engine bay, providing a durable and effective solution for your vehicle's detonation detection needs.
