OPEL Knock Sensor - Part Code 9158720

The OPEL Knock Sensor (Part Code 9158720) is a critical component designed to monitor and protect your engine from harmful detonation or 'knocking'. This sensor listens for the characteristic vibrations produced by abnormal combustion within the engine cylinders. When the knock sensor detects these vibrations, it sends a signal to the engine control unit (ECU). The ECU then adjusts ignition timing to retard the spark, thereby preventing further knocking and potential engine damage. This precise control is vital for maintaining engine health and efficiency. By ensuring that your engine operates within its optimal combustion parameters, this knock sensor contributes to smoother running, improved fuel economy, and extended engine life. It is a direct replacement part designed to meet the original equipment specifications for your OPEL vehicle.
