Advancing the valve timing of an engine improves the firing stroke and thereby, its created power. Your current Buick Rainier knock sensor will make sure you do not go over the limitation that the engine allows. It's going to produce electrical current in the event the valves are over-advanced, which often emits audible pinging or knocking sounds. The electrical current it generates is followed by your engine computer. In this case, an engine computer functions to retard the timing of the engine valves in reply to the knock sensor alert, or, in older models of automobiles, a Diagnostic Trouble Code (DTC) is definitely initiated.
The Buick Rainier knock sensor will detect pinging or knocking, which means that you have achieved the limitation in advancing your engine's valves. Pinging is just the sound which pressure waves in your cylinder creates if this collides onto the cylinder walls or perhaps the piston of the engine. This typically develops when your valve timing is advanced beyond the limit. Your sensor readily picks up the occurrence of pinging because it is made from Piezoelectric components or crystals which responds to the impact effects by simply creating voltage.
If the Buick Rainier knock sensor is undoubtedly inadequately made or perhaps currently damaged, the engine is at risk. Don't ever let this take place; get a dependable replacement coming from best brands just like Beck Arnley, Replacement, and Delphi at Parts Train!
