Re: Knock Sensor; What happens if its disconnected
Lee,
The DRM cal I looked at does not negate knock retard. Its just as I described from the FSM. I would expect a Code 43 to be set in your case but I can't explain why it hasn't. Without that, I would say the ECM is not modifying timing. Hook it back up, put in a fresh clutch and let's see what happens. Who knows, maybe the clutch was slipping. |

Re: Knock Sensor; What happens if its disconnected
The ECM does check this circuit periodically by advancing timing to trigger spark knock and checks to see if the sensor detects it. I had a bad pigtail connector and was getting a code 43 about every other drive. Replaced pigtail with OE AC Delco part from Advance Auto Parts and no more codes.
