Advancing the valve timing of an engine improves the combustion stroke and thereby, its generated power. To guide you with getting the task right is the Bmw Z3 knock sensor. It will produce electrical current once the valves are so advanced, which often emits discernible pinging or knocking disturbances. The current it makes is monitored by your engine computer. At the first indication of problem, this particular computer triggers a Diagnostic Trouble Code (DTC) or perhaps instantly corrects the Variable Valve Timing (VVT) of the vehicle.

Your Bmw Z3 knock sensor detects pinging or knocking, which means that you have attained the limit in advancing your valves. Pinging is the sound that pressure waves in your engine creates in the event it bumps onto the cylinder walls or even the piston of your engine. It is a phenomenon that is specific to super-advanced VVT. What actually get the sensor capable for this purpose is definitely the Piezoelectric materials used to construct it.

If the Bmw Z3 knock sensor is actually badly built or perhaps presently defective, your engine is at risk. Look for Beck Arnley, Replacement, and Delphi direct-replacement products in exchange to your sensor at Parts Train!
