could see the fpr failing and possibly a O2 failing as a result or vice versa. replace the fpr and clear the codes, if the other two come back, start checking upstream O2's (driver side is bank 1)
Everything about this post is wrong. FRP sensor failing will not cause the o2 to fail or vice versa. The o2 code is popped after an extremly lean or rich condition.
Bank 1 is the side with cylinder #1 which is passenger side.
OP i am guessing you are draw thru so check your piping for leaks and then check the intake manifold for leaks. FRP sensors suck and pop all the time which is why returnless systems suck on blown cars.
