Can someone please help me with this. I understand that P1646 is an O2 sensor bank 1 upstream, but where is bank1 upstream. Is it in the front or in the back of the motor and is it the top or the bottom I can see four sensors. All look to have four wires, but are they the some sensor(part number) or is each one adifferent number. Thanks for ant help you can give.

You need to make sure that the wires have not been crossed somewhere. The P1646 is def bank 1 sensor 1 code. So you either have a wiring problem to that sensor or bad ECM. I would look at ECM last.
Fuse 21 (30amp) in the engine bay fuse box controls the heater circuit for that sensor. Check that fuse. Then you need to check fuse 19 (10amp) and fuse 36 (5 amp) all in the front fuse box. Engine bay.
Let us know.
