The Knock Sensor in Cadillac DTS vehicles involves itself significantly in the overall performance of the automobile since ignition timing is erroneous in the event of engine knock. This device can communicate with the powertrain control module (PCM) so that the ignition timing can be knocked down for a reduction on excessive detonations. In most Cadillac DTS, knock sensors implement piezoelectricity to transform vibrations into electrical signals so as to capture the pressure spikes that denotes knicks. Whenever knock is sensed, the PCM reduces the ignition timing gradually until the normal combustion is regained, and the timing is gradually increasing. This process assists in preserving the expected performance of an engine besides minimizing on the risks of damages despite the lower octane fuels. Sophistication of the system is further underlined by the fact that the ignition timing for each cylinder can be varied in order to optimize operation of the engine in different conditions.
