Check engine light came on at 400 miles - I have an ARH LT setup with stock mufflers. Any Ideas? Spoke with the dealer today and there getting the new software for the computers next week - so ther not able to check codes till then. Its a 2SS M6

Did they do any tuning when they put on the headers? And are they catted? I bet it's the rear O2 sensors.

I know this sounds dumb but my 05 Goat would throw a sensor light when the gas cap wasnt screwed tight enough

Not dumb at all. Very plausible.

issman · 08-27-2009, 06:15 PM

No tuning done yet, Checked the gas cap, that wasn't it.

third1 · 08-27-2009, 06:15 PM

Yes a loose gas cap will do that, but more than likley an O2 code

issman · 08-27-2009, 06:16 PM

I't has the high flow cats & X pipe.

issman · 08-27-2009, 06:17 PM

What exactly is an O2 code? & is this a major problem

If you are running high flow cats you will set a P0420 & P0430 Catalyst Inefficiency Code. This is normal. You will need the ECM re-calibrated to get rid of it. The dealer can not make this re-calibration. They can erase the codes, but they will come back.

Contact me if you have any questions.

You might of melted an oxygen sensor wire. My car has high flo cats with long tubes and hasnt set a code. Just a thought.

GMRULZ · 08-27-2009, 09:49 PM

Mine has as well, stock mufflers, no tune, no cai, just ARH`s w/ catted x pipe. Definetly normal.

Jekyll-N-Hyde · 08-27-2009, 10:24 PM

After install headers dont you need to tune the car ?

Camarofan69 · 08-28-2009, 05:19 PM

i bet it is the knock sensor. my lt did the check engine light thing, and i had to wait 2 weeks before my dealer got the software. I hit the onstar button they did a scan, and it came back as a knock sensor. Dealer got the software for there computers ran the scan and it read knock sensor. knock sensor has been ordered it has been 3 weeks, and still waiting.
