Knock Sensor is an important element of GMC Yukon car as it is responsible for detecting an engine knock, wrong ignition timing. It transmits signals to the powertrain control module (PCM) so that it can vary the ignition timing in a bid to reduce excess detonation. In most remodels, GMC Yukon has piezoelectric knock sensors that help in real-time monitoring of pressure spikes, which suggest knocking through converted mechanical oscillation to electrical signals. The knoack sensor has developed through the years and present systems are capable of changing ignition timing per cylinder and modifying the boost pressure for improved performance and durability. These modern means make it possible to hold combustion parameters optimum, and therefore the engine will work fine even with a low octane gasoline. The application of such technology show the advancement of Knock Sensor in the shape and performance of GMC Yukon automobiles.
