Cadillac Escalade Knock Sensor

The Knock Sensor in Cadillac Escalade vehicles is very useful when it comes to rendering performance to the engines since it is responsible for recognizing Engine knock which is normally caused by an incorrect ignition time. This device communicates with the PCM to allow it to vary ignition timing and minimize detonation that is too strong. In most Cadillac Escalade models piezoelectric knock sensors are commonly used in the engines to monitor pressure peaks and knock continuously through detection of shock vibrations. Cadillac Escalade in recent pasts has integrated knock sensor that allows the vehicle to change ignition timing for particular cylinder and control boost pressure depending on the design of the engine. This makes it to deliver its expected power and to last longer on the engine, regardless of the fuel grade used. The Cadillac Escalade's knock sensor system is one of the greatest representations of modern engine management systems because of its efficiency and accuracy.

Each OEM Cadillac Escalade Knock Sensor we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
