Emmisions light is on?

07blackgt · 02-13-2009

I Just got done installing my JLT CAI, 93 Octane Tune, and my SSS Muffler Delete axlebacks on my 07 GT. I was driving up my street and my emissions light came on. when i got home i used my tuner to check my engine, and it read 02 Heater. I returned my ECU back to stock, and then reuploaded the 93 octane tune, and the emmisions light went away.

Any clue on what that could have been? and is it ok now?

Does your tune turn off the oxygen sensors?

Im not sure. Its a custom 93 Oct. Performance Tune from American Muscle. Its a SCT SF3 if that helps. Ill take a look at the tuner tommorow... The light is off now though since i re-uploaded the tune, but can i still drive it?

It's just an emissions code, it's not going to hurt anything. If you no longer have oxygen sensors, that would be the reason for the cel. The cel probably will return even with the stock tune.

Whew... Not the thing I wanted to hear from you, 07blackgt...

Eeep!

Glad to hear it won't be a problem (or lets at least hope so!

)

I'd suspect something is wrong with the tune. There is no reason for that to trigger a DTC unless there's a tune problem or a failing HO22S.
