The Knock Sensor is important in the performance of GMC Canyon engines because it identifies engine knock, a condition caused by wrong ignition timing. This device is connected to the PCM to relay information to it in order that the ignition time is varied in a bid to reduce excessive detonation. Usually, GMC Canyon employs piezoelectric knock sensors that capture oscillations directly and enable intensive pressure sharing with regard to knocking. Improved knock sensor has opened up the celebrations to the extent that one is able to fine tune the ignition timing for each cylinder, or even control boost pressure in some engine layouts. It achieves the optimal possible knock operation near the limits, thus delivering higher performance with lower octane fuels without compromising on the engine. The implementation of such systems is an example how progressed is the concept of engine management in GMC Canyon vehicles in order to serve a long time and to perform stable under different conditions of driving.
