The knock sensor detects spark "knock" also called "detonation". on a vehicle where ignition timing is controlled by computer, the knock sensor tells the computer whether to advance or retard the timing to make it stop detonating.

a better explanation is here:

hey PAUL -- I thought you had wished us good riddance!??

Anyway, welcome back.

Indeed there is a knock sensor, and it's function is as Pain indicated - our S cars do in fact have a knock sensor.

And please do not type everything in bold -- it's annoying on the eyes

Thanks
