The last couple of weeks I keep receiving a P0431 CEL. I only get the light on warmer Southern California days. It only appears after driving the car for a few minutes and then coming to a stop (Stoplight, parking lot, etc...). I inspected and can not find any exhaust leaks. I had a friends shop run it on their smog machine and it passed with flying colors so I believe the catalytic converter is working properly (When I researched P0431 here everyone said it was a bad cat but the smog results seem to say otherwise).
Next up I was going to try replacing the bank 2 downstream and maybe the upstream O2 sensor unless anyone else has a suggestion?
