If you wish to acquire more electrical power from the engine, advance the timing of the valves to as much as the system permits. And to guide you on getting the task right is the Pontiac Grand Prix knock sensor. This component is an electronic control unit that takes action to your fuel-air pre-detonation by creating voltage once it is afflicted. The particular voltage it makes is followed by the engine computer. The engine computer works to retard the timing of the engine valves in response to the knock sensor alert, as well as in older models of automobiles, the Diagnostic Trouble Code (DTC) is definitely triggered.

The Pontiac Grand Prix knock sensor senses pinging or knocking, which indicates you have reached the limitation in advancing your engine's valves. Pinging is just the sound which pressure waves in your engine creates when it bumps onto the cylinder walls or the piston of your own engine. This typically develops when your valve timing is advanced past the boundary. Your sensor effortlessly registers this occurrence because it is made from Piezoelectric materials or crystals which reacts to most influences through generating voltage.

When the Pontiac Grand Prix knock sensor is bad, your own engine computer is supplied with inaccurate details. Never let this take place; look for a efficient alternative made by best makes like Beck Arnley, Replacement, and Delphi at Parts Train!
