VAG Knock Sensor 021905377E

The knock sensor is a critical component in modern engine management systems. It listens for the characteristic vibrations of abnormal combustion, commonly known as engine knock or pinging. When detected, it sends a signal to the engine control unit (ECU). The ECU then adjusts ignition timing and other parameters to eliminate the knock. This process is vital for maintaining optimal engine performance, fuel efficiency, and preventing potentially serious internal engine damage caused by detonation. This specific sensor, part number 021905377E from VAG, is engineered to meet the stringent quality and performance standards of VAG vehicles. Its precise calibration ensures accurate detection of knock events, contributing to the longevity and smooth operation of your engine.
