Question:
Garage now says it is the knock sensor (not so sure). What is that and what does it do? Car is running fine with plenty of pick up and no pinking that we can tell. If that is replaced and light still comes on, any ideas about what else could be the problem.

The knock sensor retards the spark if preignition takes place. Preignition, or spark knock, is when the fuel air mix ignites too soon, before the piston has come to the proper place at top of the cylinder. Preignition is often incorrectly called "valve noise" because it sounds like tapping valves, except it doesn't happen all the time.Hyundai QarmaQ ... How much is it? Id like one.?
The knock sensor is like a small microphone (usually a pietzo-electric pickup) that "listens" for spark knock. If it detects it, the computer will retard the spark a bit to prevent it.
