Chevrolet Cobalt Knock Sensor

The Knock Sensor installed in Chevrolet Cobalt cars is responsible for the detection of the knock which is a phenomenon that arises out of wrong ignition timing. This unit communicates with the powertrain control module (PCM) which then alters the ignition timing in order to reduce detonation. Usually, knock sensor is piezoelectric; it translates mechanical pulsations into electrical impulses which are analyzed for pressure spikes corresponding to knocking. It is noteworthy that for quite some time, various Chevrolet Cobalt models are equipped with such systems as knock sensor control, which makes it possible to regulate the moment of ignition with unprecedented accuracy and, for example, for each of the cylinders. This capability is useful in attaining the premier performance of the engine while at the same time protecting the engine from damage more so when it is operated using low octane fuel. The system works in such a way that conditions change in a way that will permit the engine to work efficiently and last long.
