Advancing the valve timing of your engine will surely improve its own firing operation and thereby, its generated power. And to guide you with your task is the Toyota Cressida knock sensor. The part is an electronic control unit that takes action to your fuel-air pre-detonation by creating voltage the moment it's afflicted. The particular voltage it generates is regulated by your engine computer. From the very first manifestation of problem, this computer triggers a Diagnostic Trouble Code (DTC) or in VVT vehicles, quickly retards the pre-set Variable Valve Timing (VVT) of your automobile.

If you will advance your current VVT, make certain that the Toyota Cressida knock sensor is functioning just fine so that it can help you find the secure timing of your own valves. Pinging is just the audible sound which pressure waves in your engine creates if this collides on the cylinder walls or perhaps the piston of your engine. It's a phenomenon that is unique to overly advanced VVT. But what get the sensor effective for its purpose is definitely the Piezoelectric materials employed to construct it.
