The knock sensor's work is to detect vibrations caused by your engine. A bad knock sensor results in stalling of the engine and you will experience a lot of vibrations. The torque is also lower than normal and your vehicle won't accelerate properly. The given slideshow shares the symptoms of a bad knock sensor in a BMW X3.
