Chevrolet Tahoe Knock Sensor

The Knock Sensor in Chevrolet Tahoe cars work to identify engine knock; this is an occurrence that is derivate from an improper ignition time. This device is used to communicate with PCM so that the ignition timing can be adjusted to reduce excess detonation. Commonly, the Tahoe comes with knock sensors that employ piezoelectricity, meaning that they promptly and constantly capture pressure spikes associated with knocking. Knock sensors have developed through the years and the newer designs are capable of diagnosing knock per cylinder, allowing for retarding or advancing the ignition timing per cylinder and as well as controlling boost pressure for some engine designs. This means they are able to set the engines to run at the maximum or nearly the maximum ' knock limit ' and get good performance without risking the engines even with low octane ratings fuel. Incorporation of such systems in the Tahoe represents optimization of engine management systems and their development for durability to maintain performance.

Each OEM Chevrolet Tahoe 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.
