Check engine light will not go off it is own because of knock sensor. I have had it scanned and reset and it comes back on. So I fixed knock sensor and harness and still comes back on. Now I worked on it again to check everything and I tried to reset the service engine soon light by disconnecting the negative battery post and turning headlights on to drain stored power and it still will not go out.
