Here is the error from INPA and its calling out bank 1 valve being stuck. I replaced both valves and hose, so Im tripping out here. I scoped the ports when I replaced and both were clear. Can I turn on the secondary air pump with INPA? I would like to do this to check the air flow if possible. Here are the translated errors...lf I was to remove the outgoing Y-hose from the pump and start the car wouldn't I get back flow from the engine exhaust if the valve was stuck open?

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.

Yes, that’s the one. I got the hand gun bore cleaner at Turners. It’s segmented so you can put one in, then the next……
