Knock Sensor is an essential element in GMC Terrain, which is used for the recognition of the knock that happens inside the engine and conveys signals to the powertrain control module to alter the timing of ignition. This reduces detonation in the ignition cycle hence improving the engine efficiency and the durability. Usually piezoelectric in nature, the knock sensor measures fluctuations, that constant check on the pressure spikes which is knock. In this fashion, the system continuously maintains the external ignition timing a degree or parts of a degree on the 'knock limit' side, even with lower octane fuel. Sophisticated mechanisms are able to control quantity of time for each cylinder and also the level of boost pressure and as such demonstrates the development and further improvement of various technologies in the role of eradicating engine knock.
