The BOSCH 0 261 231 226 Detonation Sensor is a critical component designed to monitor and identify abnormal combustion events within your engine, commonly known as knocking or detonation. When detonation occurs, this sensor detects the resulting vibrations and sends a signal to the engine control unit (ECU). The ECU then adjusts ignition timing and fuel mixture to prevent further knocking, thereby protecting the engine from potential damage and ensuring optimal performance. This sensor plays a vital role in maintaining engine longevity and fuel efficiency. By ensuring proper combustion, it helps the engine run smoothly and prevents the costly repairs associated with detonation. Ensure your engine's safety and performance with this high-quality detonation sensor from BOSCH.
