I'm not sure if it does or not. If it does, it is probably located under the intake manifold, but I am not 100% sure of that either.One thing I do knopw about, is that the knock sensor retards your timing in order to prevent detonation. When it detects a spark knock, it will do it's job. Un-necessary retardation of timing will give you a loss of power, and a loss in gas mileage.
