My next step is to follow the procedure for Detonation Sensor diagnostic. It tells me to check the ECU harness connector and detonation sensor continuity. And then check the continuity between the detonation sensor sub-harness connector and ground. That's it, other than check the pins on the ECU harness connector. : Off hand I don't thing 1/8" would be enough to throw the code but.. : 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.
Yes, I just turned the screw CW... waited for 2 seconds and turned it CCW and started flashing the code.
