Code 43 ???
Ok here's the problem. I have a code 43 coming up and I went through all the procedure to test it out and I was getting 9.4 volts which would make the problem in the connection at the ECM or the ECM is bad. I have checked the connection and just to make sure it was good I scraped the terminal and put some electrical grease on it with a tooth pick. That didn't seem to help, it still comes up. Now here's the question. Do I need to reset the check engine light everytime I try something?Or will it go away on it's on if I fix the problem. And if it's the ECM is there somewhere I can get it tested? And can the ECM be bad only in that respect? Everything else seems to be doing just great. And will it hurt anything if I drive it with this code on?

1. yes you need to reset by disconnecting neg cable for 10+ seconds, it will not reset itself. and it will not go away even if you fix the problem.
2. Don't know if anywhere you can get it tested...
3. Code 43 - can be caused by a faulty connection at the knock sensor at the ESC module or at the ECM. you could also check CKT 485 (black wire) at position B7 at the ECM.

Re: Code 43 ??? (vinnies87)
I'll reset it , I hope thats what it is. I have checked connections at the knock sensor and the ecs and at the CKT 485 black w/yellow strip B7 connection at the ECM. Also the whole motor has been overhauled and all the sensors on the motor and on the car have been replaced so I know they are at least all new.
