Jeep Grand Cherokee Knock Sensor

Jeep Grand Cherokee's Knock Sensor has the responsibility of monitoring knock and ignition timing that is off in an engine. It transmits signals to the powertrain control module (PCM) so as to adapt the ignition period to control severe detonation. Usually, Jeep Grand Cherokee models incorporate piezoelectric knock sensors that make it possible to monitor pressure spikes that signify knocking on-going for a while continuously. Modern knock sensors have been used to fine-tune control strategies and that have included the flexibility of being able to program ignition timing per cylinder and control turbo boost pressure. This enables the engines to perform as expected even when using lower octane fuels and at the same time, reduce the chances of damage to the engines. The incorporation of these systems is a policy of keeping the efficiency and durability of the engines in different models of the Grand Cherokee.

Looking for affordable and high-quality auto parts? Then you have already arrived at the proper online shop. We offer all Jeep Grand Cherokee Knock Sensor at great affordable prices. Moreover, all genuine Jeep Grand Cherokee Knock Sensor come with a manufacturer's warranty. In the long run, you would realize you have saved a lot of trouble and money with OEM parts from here.
