Knock sensors detect abnormal vibrations in the engine. The system is designed to reduce spark knock during periods of heavy detonation. Knock sensors produce AC output voltage which increases with the severity of the knock. The signal is fed into the PCM and the timing is retarded to compensate for the severe detonation.

knock sensors operate the same in every vehicle. when the engine "pings" or called spark knock( due to bad gas or low octane fuel, carbon build up on top of pistons or valves) the knock sensor sees this and retards the timing. vehicles now days, timing is not adjustable by u or me, only through the computer using the knock sensor and other sensors. master tech 26 yrs.
