In Reply to: I just did a self diagnostic. I pulled the "Detonation Sensor" code. --> posted by Aaron on July 15, 2002 at 18:57:49:
did you have the check engine light on? And you just did the turn the screw on the ecu and read the blinks diagnostic? Knock sensor is a pain to get at. Upper and lower intake manifold have to come off(lower manifold gaskets are expensive). Try cleaning the harness that the knock sensor attaches too. : Remember when i posted up here saying that my car is 8 tenths slower in the 1/4 mile when it warms up to operating temperature? Well, I think I found the problem. : I have a FSM and I followed the diagnostic procedure and got a detonation sensor code. I advanced my timing not too long ago. I turned the crank angle sensor no more than an 1/8". I still haven't actually checked my timing with a light. : My questions are: : Who has replaced a knock sensor in the VE? How hard is it? How long does it take? : Do you think that since I advanced my timing, this is the reason why it's throwing this code at me? : Or do you think the knock sensor is actually messed up? : Thanks.
Off hand I don't thing 1/8" would be enough to throw the code but..
