anyone?
Bank 2 is the passenger side on your truck. What's your code? it may not need a sensor.

air fuel Mixture
P0171? P0174? If it's a mixture code a sensor will not fix it.

O2 sensors usually read po420 sensor 1 p0430 sensor 2
bigblock72 I like your avatar.
My Yukon pops up p0404, oxygen sensor voltage out of range. Does nothing to effect economy or power, so ignore it and the light goes out. I comes on and off occasionally.

does it say rich or lean? that code usually doesnt set for just an o2 sensor.
lean, could be clogged filter, weak pump, bad pressure regulator, clogged injectors/fuel rail
rich, could be bad regulator, stuck open injector, even worn out plugs not burning all the fuel
dont just throw an o2 sensor at it, it wont fix it

Well since it was tuned up recently, and the fact that it affects the performance and economy not one bit, I don't bother with it. Prolly just a loose wire somewheres that causes the situation. O2 sensors? 
I'll deal with the hit in fuel economy.
