It is used to detect a knoch and change the timing to try to reduce the knock. It's primary fi=unction is to keep down detonation. So if you have a loud knocking on acceleration, it could br crank bearings or possibly the thrust bearing allowing the crank to move too fat and causing the flywheel to hit rear of engine.
