O2 Sensor Check Engine

O2 Sensor Check Engine
I used to have an 01 GT and when i installed the new exhaust i got the check engine light . I was able to clear the fault with the diablosport and it never came back . I now own an 09 gt/cs and i did the same thing but the check engine fault for the o2 sensors keeps on coming back on a daily basis after being cleared. ANy ideas?

If it's code 2195 or related you may have an issue with the tune and your longtubes. It's federal law that rear O2's can't be turned off so the extra flow from the long tubes sets off a code.

A user can't turn the O2 sensors off with a Diablo OR an SCT. You need a revised tune. Contact your tuner or call AM or Brenspeed if you didn't get custom tunes from them.
