How difficult to change sensor 2 bank 1 o2 sensor? I do not have a lift.

Seems pretty easy.

Shouldn't be too hard...it's the sensor downstream of the catalytic converter...just lay under the truck and remove the old and replace with the new

Not hard at all. May be a little tight from corrosion/heating and cooling of exhaust, but it should still come out fairly easy.

For what it's worth, when I got my 02 light I replaced all 4, mostly because I'm OCD but anyway my point is, I cut the wires to the old sensors and removed them with an impact wrench, unplugged the cut pigtail, then reinstalled the new ones with lots and lots of high temp never seize, and plug the new ones in. I had all 4 replaced in under an hour, did I say use lots of high temp never seize? It will happen again.
