    First, P20051 isn't a valid code. you have too many numbers in there.

    P2195 B1S1 stuck lean would also give you a P2270 B1S2, so fix the B1S1 first and the B1S2 should correct itself.

    I have 3 02 sensor codes on my 2009 Kia Sedona they are P20051,P2195 and P2270

    Can all three sensors be bad or just one.How can tell which sensor is on bank 1 or bank 2?

    I would not think that three sensors would go bad at the same time. Why not believe what the code is saying and fix the bad injector or what ever is causing a lean reading.
