This is such a PITA code. Last year after doing CBE and LTH's it was fine. Then a few hundred miles later it started coming on. I'd reset it but it would always come back within 20-30 miles. Finally got Uprev and just turned the code off till I could get it tuned thinking that the car was just running a little too lean with the plan to re-enable it after the tune. Long story short after it was tuned and the code re-enabled the damn thing came back after a few hundred miles. I watched the dyno runs myself along with the AFR's so I know everything looks good. I'm turning this code back off this weekend when I get a chance.

That's what I was trying to find out exactly was if you could turn this code off.

It's in the same list as all the other DTC's that can be enabled or disabled. Just need the Uprev tuner cable or have your tuner do it for you.

It makes sense in your situation, but my exhaust is all still stock for now so I don't understand why it came on. The only other thing I could think of is a conspiracy against my nissan dealer. After I installed my stereo I went in for the steering lock recall. Since then the CEL has shown up. So far after I cleaned the MAF's it hasn't shown up, but if it shows up again I'm blaming nissan lol

Update:

The CEL came on once again. I jacked up the car and noticed the metal mesh in the Y pipe was missing a chunk. Would that have anything to do with it?

Yes. That is creating an exhaust leak which is affecting your O2 sensors.
