CEL, 2 codes - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

For some odd reason today the camaro decided to throw 2 codes, P1153 and P1133. I do have LT's and the car is TUNED. I understand this is o2 sensor related but Im curios as to why the code would be thrown with a tune? I sent an email to my tuner but its after hours..so do you all have any suggestions?

Pretty sure those are switching codes(don't have my laptop with me) Pretty common for those to come in on the cold days.Takes longer for the 02's to heat up. I ussually delete them.

Thanks Slowhawk, I cleared the codes and they have yet to come back, the LTFT's are in check which is what I was worried about.

Those codes are lean condition on the rear cat. Is this nothing to worry about?

That's not it. Those are the front two sensors and like others have said, related to the cold weather. The tuner should have taken care of those.

I have P0174 on mine. CEL came on when the weather was cold. Today it was 75 degrees. CEL went off. Go figure.

Hmmm that's a lean fuel trim code. Maybe your tune is on the edge of lean and the colder dense air is causing it to go even more lean. Or you have a small exhaust leak upstream of the cat on bank 2.

Well my car just threw the same 2 codes and I am not tuned but do have long tubes.
