Ok so while I was doing some stuff I broke the wire on the knock sensor connector too close to put it back together, so I cut the other half of the connector off and hooked the loose wires together. Now my check engine light comes on once in a while, usually after driving a bit, throwing the knock sensor code. It goes away if I stop the car and start it, but the code is still in the ecu. So I've cleared the code and it comes back. I just can't seem to get it to go away, no matter how many different ways I reconnect the wire. Is there any other possibiliy that would cause the check light to come on other than a bad connection?

Also, the ECU fail safe method for knock sensor is retarding the timing 2 degrees. Does it run this way until I clear the code, or is it only doing it while the check engine light is on?

it would always be that way if the code is there weither the light is on or not.

I would try to fix the wire better?

 

I have reattached the wire 100 times. I've used various crimps and connectors. Nothing seems to do the trick. So I want to believe it is something other than the lack of connection that is causing it.

 

maybe it is just a coincidince, but check out whateer the engine teh ecu is telling you is wrong. Perhaps you knocked the wire out, and now thing the is frigged.

 

The ECU doesn't say what is wrong with it. It just throws code #5 which is the knock sensor. It tells you what part is giving an error, not whats wrong with it.

 

maybe its actually knocking....

 

Maybe, but I set the timing almost perfectly. And it runs perfectly fine w/o any hiccups or anything.

Oh, and it never did it before I broke the wire...

 

Just tested it and I have continuity between the knock sensor and the 2M pin on the ECU, and I'm still getting the code. Does this mean I need to replace the knock sensor?

Would the ECU throw a code even if it were knocking?

 

Did you try soldering it? From my experience, crimps don't work very well for long, so you might want to try it.
