In case you need to create more energy from the engine, advance the timing of its valves as far as your system permits. And to guide you with this is the Buick Lucerne knock sensor. It will create current when the valves are over-advanced, which often produces discernible pinging or knocking noises. Your sensor utilizes its generated voltage as signal to your engine computer. Your engine computer works to retard the timing of the valves in response to the knock sensor warning, or, in older models of automobiles, a Diagnostic Trouble Code (DTC) is definitely activated.
When you advance your current VVT, make sure that your Buick Lucerne knock sensor is functioning perfectly and thus, will help you find the safer timing of your valves. It'll sense pinging in the engine at the very first indication, which means that pressure waves are getting off specific ignition point too soon that it crashes to your cylinder walls or on the piston. This specific occurrence generally happens when the actual valve timing is advanced too far. Your sensor readily picks up this because it's made from Piezoelectric materials or crystals that acts to the impacts through producing voltage.
When the Buick Lucerne knock sensor is actually poorly made or already damaged, the engine is at risk. Look for Beck Arnley, Replacement, and Delphi direct-replacement products for this sensor at Parts Train!
