So I'm pulling a P0156 which is Bank 2 sensor 2. Where is that in relation to the car? I think one of my MILs shorted out. I bought them from a place here in town, but it was really rainy outside today and I think water may have fux0red it. I'm just trying to find out which one to replace.

Well its the lower O2 sensor on the front header and that is a monitor O2. I would re-set the CEL and see if it comes back. If it does, u know you have a problem.

I get a catalyst efficiency below threshold back 2 code about once a month. It usually happens when it’s below 45 degrees. The light goes off in a day or two and comes back in a month.

If water got in the wiring harness maybe. I would take a look at the MILs and sensor wires to make sure everything is good than re-plug in the MILs and see what happens.

i get code p0136 i believe. Bank 1 sensor 2. I also have gutted precats and MIL's. Its basically a worthless code, and i dont konw why its popping up on mine either, because i have MIL's.
