The Knock Sensor in Toyota Sequoia automobiles is an essential part that has the function of detecting knocking in the engine and transmitting signals to the PCM so that proper timing can be made. Usually piezoelectric the sensor is trying to measure vibrations and convert them into electrical signals or pressures that show knock occurs. This facilitates timing control in order to achieve the prime results and to avoid detriment on the engine particularly when operating with low octane gasoline. Sophisticated ones can even control the times for each cylinder and also control boost pressure to maintain maximum efficiency and durability in different environments. The Knock Sensor helps in preserving engine efficiency and preventing hazardous detonation and therefore is an essential component of the car.
