P0422 and P0432 on a T6

So lately the Volvo's been kind of a money pit, but I'm not ready to give up yet!

A couple months back I had a failed turbo that caused a TON of thick smoke, took it to a repair guy who swapped one of the turbos and everything went back to normal. Now I'm trying to get it through DEQ (Oregon Resident) and as soon as Catalyst goes to a ready state (about 3 driving sessions), I get these two codes, P0422 and P0432.

I'm wondering if the thick smoke wreaked the cats or o2 sensors....

Any thoughts?

O2 Sensore do go bad too. Replaced both with Bosch.

Any way to test the current o2 sensors? I have a scanner, a multimeter, and some electronics knowledge

Also, are both of the front banks the same part number?

I think I found the right two
Bosch 17135
Bosch 17136

Thanks for the help ThommyKent!
