Oxygen Sensors
I have a 2000 F-250 with the V-10. I am trying to find out FOR SURE how many oxygen sensors it has. I looked myself yesterday and found 2, both on the upstream end, 1 on each side of the Y-pipe and thats it. I call the parts store to get them and they say its supposed to have 4 total, 2 upstream and 2 downstream. After i called them i called the ford garage and they tell me its supposed to have 3 total, 2 upstream and 1 downstream. After that i went back out and looked again, still cant find any downstream, i looked up by the manifolds as well and there are none up around that area either. I find it off that the v-10 only has two sensors. Im almost positive that the 5.4 and the 4.6 both have 4 total. Am i missing something here? Everytime I get in a bind with something I come here and always seem to get the best answer here. Any help would be appreciated. Thanks.

OBD1 calibration vehicles have two sensors, OBDII calibration vehicles have four. Consult the emissions label under the hood to see what you have.
It all depends on what state the truck originally shipped to - whether it was to one of the "Green states" or any of the others.

I was not able to find mine (01 5.4 F250) last time I looked. Anyone able to say exactly where it should be located and/or embed a pic?
TIA

It should be right up front, on the radiator core support.
