OBD2 problem, 2000 F250
Hey all,
I have a 2000 F250 with the 5.4l. I'm due for an inspection, but my oxegen sensors aren't ready, even after hundreds of miles of driving. Even after changing what I though was a bad sensor, my scanner is still reading no signal from that bank. Any ideas?
Thanks,
Matt

Take a look at the wire harness and the connections to the sensors.

Yea, everything's fine. I checked all the fuses in the truck and all that jazz.
I'm gonna toss the scanner on it right now and get exactly what it says; it's been a while since I messed with it.

I would be in favor of a bad wire if your getting the same fault even after changing the O2 sensor. A multimeter would be able to check that for ya.

Turns out, your 2000 Superduty is NOT "OBD-II compliant" but it has an OBD-II connector to talk to the computer.
What state are you in?
In New York, I had the exact same problem. One year, it was just a matter of putting in "F250 Superduty" instead of "F250". Next few years, not so simple.
They had to change the "weight code" to be "greater than 8500lbs".
If you have passenger plates, they will look at the registration which shows the unladen weight, which is below 8500lbs and they will want OBD-II compliance.
If you have commercial plates, with the GVWR on the registration, it shows 8800lbs, which is over the 8500 lbs and they won't do the OBD-II check. They might do an idle sniffer test instead.
To reiterate: Your truck will NEVER show O2 sensor readiness because it's not OBD-II compliant. Your inspection station has to have some way to get around this, but they may not know about it. They might have to call the state's DMV/whatever to get around it.

Wow, that's wild.
It makes me feel better to see that, because my scanner read "OBD1" support from the truck, so that always worried me.
I live in NYC, so I'll have to speak to my inspection guy and see what he can figure out.
Thanks alot for the help though, at least I know there's nothing wrong with the truck.

Matt, do you have passenger plates?
If so, they are probably going to give you a problem, and it shouldn't even be hooked up to the OBD-II scanner in the first place.
If you have commercial plates, they won't hook it up because it will be over the 8500lbs cutoff, because your registration will say "8800 GVWR"
Passenger plates, again, it will read the unladen weight, which for my SD is 5700 lbs or so. They have to manually key-in that the "weight code" or "weight class" is over 8500lbs. Then, the machine tells them to do a sniffer test.
(which, as a side note, the limit on the sniffer test for HC's is so darn high, that my '74 highboy with hi-po 390, lopey cam, and 11:1 compression would pass it WITHOUT a catalytic converter. I suspect that a V10 would also pass without the converter)

The 2002, which I used for a while as a DD, did have pass plates on it. I got that one inspected, but next time around I'll try it your way and hopefully it wont be a problem.
