The DELPHI AS10243 Detonation Sensor is engineered to monitor your engine's combustion process. It accurately identifies abnormal combustion events, commonly known as knocking or pinging. By detecting these potentially harmful vibrations, the sensor sends a signal to the engine control unit (ECU). The ECU then adjusts ignition timing to prevent further knocking, safeguarding your engine from internal damage and ensuring it operates at peak efficiency. This sensor is a crucial component for maintaining engine health and performance. Its reliable operation contributes to smoother running and can help improve fuel economy by ensuring the engine is always running under optimal conditions.
