Can't be certain, but my guess would be that "sensor stuck rich" code is the more causal one. If the computer is trying to trim out a nonexistent rich condition caused by a bad sensor, the (still good) post-cat sensors screaming about an actual lean condition make sense.
Both post-cat sensors reading a lean condition is bad, regardless. Don't drive the car like this. |

I got 2 of your 3 codes after I put on my section 1 pipes. Since they are post I wasn’t to concerned. I did eventually replace the post o2 sensor and reset the codes, they haven’t returned.

That's quite an assumption. Feel free to make it, of course, but if the ECU is actually trimming fuel based on the "stuck rich" input due to a bad sensor, your car might actually be running lean on that bank.

Do you have a tuner in your area? If it were me, I would have it diagnosed. Maybe a custom tune will rid you of the problem. |
