So I swapped my primary O2 sensors and my code remained the same. Also swapped out brand new donut gaskets as well while I was under there. Curious, since we're both from CA, are your monitors all not showing ready? I can't get my O2 and Secondary air monitors to show ready and assuming it's because of my pending code 27B1. |

27b0...Oh how I know this code well. Chased it for so many years. Finally had it coded out.
I believe this is a result of carbon build up in the ports that you really can't fix without removing lots of stuff.

Yeah I scoped them when I did the valves but honestly I'm not a mechanic so I'm leaning towards this or my cat.

Yes, I have another detailed thread on what it was and how I fixed it.
