CEL 2 months after tune

6MT · 09-11-2011, 07:21 PM

Well, not very many. But there is no input from those two sensors... so I'll never see that code again (and I did before the tune). And no, I haven't had any trouble. (only 1K miles since tune)

I got the a tune thinking it would fix it but it came back after a 100 miles. Thought it could have been my stillen G3 so I took it off. After another 100 miles the same codes came back. So I definitely know it's the Art pipes that's causing it. Funny how the Art pipes V1 I had prior didn't cause CEL codes.

you think there is a solution for the issue? i just used my hypertech to clear the code.

Yes, your tuner can eliminate those two inputs with Osirus when he does your tune. I'm very surprised that those that are doing these UpRev tunes don't realize that and remove them. Especially with the high flow exhaust systems that most people change to. Those two rear sensors just don't have a wide enough voltage spread (bandwidth) to operate without throwing codes. Solution = remove their inputs.... and NEVER throw another code from them.

^ you just clear it each time it pops up?

Well I found the reason for my cel issue. Turned out that one of the cai pipes heading into the right throttle body worked loose from the hose clamp and the motor was sucking unmetered air. I put things back the way they should be and I haven't seen that code in over a month.( my bad).

I'm currently trying to get rid of a "permanent" code P2A03 right now. I had an exhaust leak at the header/test pipes on the driver side for about 200 miles. The code confirms 02 bank 2 sensor 1, which is the driver side sensor. The car immediately threw a CEL. I fixed the leak two weeks ago and shortly after cleared the CEL with an OBDII scanner. The code is still showing after two resets. Any idea how to eliminate the code? Will the pedal ECU reset do the trick?
