    My bank 2 sensor 2 O2 gave me a check engine light so I had it replaced. One mile down the road it comes back on, same code. My shop guy says next step is to look for a problem in the wiring harness. That will be Monday, but I thought I'd check with you guys to see if there is a known issue with wiring to point me in the right direction.
    TIA

    Ha I just cleared the code today and it hasn’t come back, it comes and goes, who knows if it’s the cat, sensor or a actual exhaust leak.

    My inspection is still good till next year so I’m not to worried about it right now haha
