Toyota Highlander Knock Sensor

Knock Sensor is used commonly in Toyota Highlander to check for engine knock which occurs when ignition timing is off. This appliance works hand in hand with the PCM to allow the PCM to alter ignition timing in such a case as optimum detonation. Commonly, knock sensor is piezoelectric and transforms the vibration signals into electrical signals which are then regularly checked for pressure surges associated with knocking. For quite some time, several Highlander versions incorporate developed knock sensor technologies for fine tuning of ignition and for cylinder basis. This capability enhance the performance of the engine in its prime optimum and minimizes the possibility of damaging the engine when using low octane fuel. With the help of the system, it can under any circumstances provide the efficient work of the engine and provide its long service life.
