I believe bank one sensor two is the passenger post catalytic converter (it's actually mounted on the side of the catalytic converter if i remember correctly.) i don't have the shop manual with me at the moment but i'm pretty sure that's how it is.

You are correct It is located on the rear pipe of the right catalytic converter on the passenger side.
