How do I access rear A/F Sensor on Sienna ?

I have a 2001 sienna, odb code 1135 = rear air fuel sensor. I can get
the part for $238. what I can't figure out is how to get to the rear
a/f sensor on the exaust manifold. Do I take off the wipers and
plates and all that to access the part from the top of the car, or
should I shimmy underneath and reach up? Anyone done this yet? The
dealer wants $450 installed.

I would try to reach up from underneath before taking a lot of stuff apart.
