BMW 525i Replacement Knock Sensor Information
Many drivers don't know exactly what the knock sensor does in a car. Like other sensors, it monitors engine operation to increase performance. The main function of this device is to detect vibrations caused by engine knock. This data is sent to the powertrain control module, which alters ignition timing and prevents detonation. Knock sensors ensure that you are getting as much power and fuel economy as possible from your engine.
This sensor is usually located in the lower engine block. If it fails, you may experience poor acceleration and reduced fuel economy. The symptoms of a damaged knock sensor show up at highway speeds. The knocking action can destroy the valves, plugs, rods, pistons, and gaskets. Your car's computer will detect a bad sensor and enter fail safe mode. Failure to replace this device can lead to extensive damage to the engine.
