So a few weeks ago I got caught in a flash flood and although the deepest I sat in was ~6-10inches, I did drive through probably deeper as I went down and up some hills trying to get away from the flooding. Since then I have had two problems, rattling in my exhaust from a cat breaking and maybe 80% of the time I check my passenger side O2 sensor isnt working. Today I caved and gutted my cats to be done with the rattle and I swapped the O2 sensor while I was at it. After starting my car the O2 sensor is still not working properly which is quite a bummer as I had to pull my header to get the old one out. I assumed the wiring was ok as when the sensor is not working its reporting ~3V but now I am not sure what to think or do with this.
Any help would be greatly appreciated.

Faults are p0031 and p2237. Sometimes it's just one of them, sometimes it's both. I disabled my downstream sensors a while back as I couldn't get them to fit with the last set of cats I installed. Car is now catless and is still on the same tune as before and the traction control is off.
