Well now I feel a little bad! Haha.
I just want to be sure your up stream sensors aren't in the downstream position, and downstream in the up. If that were the case likely you'd have other codes too, but it doesn't cost anything to check, right? Where as if we have to get you new sensors, there's some bucks spent.
Both codes you linked suggest however that your bank 1 sensor 2 is no longer functional. Someone with data logging capabilities or a live data scanner near you should be able to read the voltages from the O2 sensor and see if they are normal.
