Advancing the valve timing of an engine improves its power stroke and thereby, the generated power. Your current Mercury Villager knock sensor ensures you don't exceed the limitation that the engine can allow. This component is a kind of electronic control unit that responds to your fuel-air pre-detonation by producing current when it's afflicted. The actual electrical current it makes is regulated 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 vehicles, the Diagnostic Trouble Code (DTC) is definitely activated.
Your Mercury Villager knock sensor senses pinging or knocking, which signals that you've reached the limitation in advancing your engine's valves. It'll determine pinging in your engine right at the first symptom, which means that pressure waves are getting off its specific ignition point too soon that it crashes to your cylinder walls or on the piston. This is a happening that's incomparable to overly advanced VVT. But what make your sensor effective for this function is the Piezoelectric materials employed to construct it.
If the Mercury Villager knock sensor is actually poorly made or maybe already defective, the engine is at stake. Never permit this to happen; get a reliable replacement made by best makes just like Beck Arnley, Replacement, and Delphi at Parts Train!
