Oxygen sensor replace
My '03 triton is showing code PO171, and the diagnostic reads no voltage from 02 sensor 1, bank 1. I don't know exactly where this sensor is located (I haven't looked yet). I think I would like to swap sensors between bank 1 and bank 2, then run diagnostic again. Is that a reasonable plan?

The o2 sensors are just after the factory manifolds on the y pipe.
Have you thought about using a meter to check voltage from the harness or to test the sensors resistance?
Either way if you do swap and the sensor is fouled your plan should work.

Passenger side is a reach, you can see it in this photo only because my pipes are cut off during the header/exhaust project I was doing. You need octopus long arms and an O2 socket, or offset socket.
