CELs After Tune - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Ironfall96 · 11-10-2010, 05:57 PM

Here's the story. After I installed my headers/exhaust my CEL came on. Since I have no cats, and I took out the rear o2 sensors, I just figured that was the CEL. I got a SCT tuner from Jannetty and uploaded his custom tune and wah-la, CELs are gone. But after a day my check engine light came on again so I went to AutoZone to get it checked out. Here are the codes.

P0036
P0056
P0140
P0141
P0160
P0161

The guy said they were all exhaust related, but if Jannetty got rid of the O2 senors where are these coming from?

If someone could show me where I could find out what these codes are it would be much appreciated. Would it be fine to just make the codes go away with the SCT tuner or should i worry about these codes?

Go to google and enter the pxxxx trouble code and it should give you the cause and pernaps the cure on OBD II ECM's. You do have numerous exhaust codes. You might want to check again with Ted to see if he was aware of all exhaust parts you eliminated and wanted him to correct with regard to the tune and headers and new exhaust.

Yeah that. Seems like a logical first start seeing how he's been selling these to very happy customers for a while now with good rep for helping resolve issues.

He hasn't got my money yet, but it's coming based on that alone. Now if only he sold Kooks.

All of those are rear o2 sensor codes.

Hey guys I googled the problem and found a post on C5 with the same codes I had. Ted commented saying when he turns off the rear senors, he expects the owner to keep the senor plugged in and zip tied somewhere I'm guessing. I on the other hand took both sensors off and stored them in the garage. I'll have to contact Ted so he can turn these off.
