I also got an SES light 480 miles after installing ART pipes and it was on my way to get tuned. They tuned it, runs terrific. Even went back and forth to NY the week after the tune.

Well, 4k miles (NY trip + 1 month) after the tune I got the SES light so I did a manual reset using the gas pedal and stop/start button sequence. It lasted 430 miles and came back. I went to Autozone yesterday and used their reader to show the code, P2A03, and I reset it again. 42 miles later it came back on. Now tonight I'm seeing P2A03 and P2A00 on the reader. I emailed my tuner a few minutes ago and hopefully I'll get a quick response.

I know I have not bottomed out in the car, I'm very careful. The car doesn't sound any different, my ears don't detect a leak. This is annoying. The car doesn't appear to be running any differently either. Seems like I have full power.

I have had the issues since installing my MXP test pipes. And had my car tuned. I believe its the 02 sensors need to be replaced.

Huh, subd for solution. I'm planning to have tune done this fall; hopefully you get to the bottom of your issue.

Thanks.

There goes your tune....

Shouldn't be the case. I'm still able to scroll thru the maps after resetting my ecu. The UpRev is still there.

If you had an UpRev tune, did your tuner eliminate the inputs fro the 2 rear o2 sensors? He should have. And you'd never throw that code again.

Footloose301 · 09-11-2011, 07:08 PM

Doesn't look like it....

If he eliminated them then the SES wouldn't be coming on

Yes, that's right. He should have eliminated the inputs from the 2 rear sensors, left the heaters on (for cold start idle issues), and you would never see that CEL again no matter what you do to the exhaust.

Footloose301 · 09-11-2011, 07:18 PM

So you haven't had an SES light since your tune? How many miles on your tune so far? I made it a little over 4000 miles and then it came on.

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)

By eliminating inputs from 2 rear o2 sensors, do you mean permanently disabling them or temporarily disable them while tune is being done?

Permanently remove their inputs to the ECU.

I have the same 2 codes after I installed my art pipes..

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.
