The FEBI BILSTEIN 105755 Detonation Sensor is a critical component for modern engine management systems. It plays a vital role in preventing engine damage caused by detonation, also known as knocking or pinging. When the sensor detects abnormal combustion vibrations, it sends a signal to the engine control unit (ECU). The ECU then adjusts ignition timing to retard the spark, thereby preventing the harmful detonation event. This precise control ensures the engine operates within its optimal parameters, maximizing power output and efficiency while minimizing stress on internal components. Engineered to meet stringent quality standards, this sensor provides reliable and accurate readings. Its robust construction ensures durability and long-term performance even under demanding operating conditions. Replacing a faulty detonation sensor is essential for maintaining engine health and preventing potential costly repairs.
