Ok guys lots of info I'm checking all that you guys have given me now I need some more help my O2 sensor bank 2 sensor 2 says low voltage but I have replaced 3 times so I doubt its the sensor I want to know where the wiring goes to so I can change the wiring out and see if that works!

My friend, I think it might be time to pay someone some diagnostic time. If for no other reason but to put you on a more narrow path. But I will throw in my 2 cents before you go there.


Might want to check ground G107. It is a common ground for the field coil circuit (alternator) and ground for the O2 sensor heaters. It will probably have multiple wires going to it. Note that just because the main connection to body may look ok, a single wire can be oxidized/corroded so that there is resistance between the loop connector and the wire.
