Hi,
As far as I know, there's no temperature problems. The dealer seems to think that the newly installed sensor might be bad. I don't know how likely this is, but I guess it's possible. He disconnected the sensor from the computer and it started up perfectly. Strange...
They're keeping it overnight to try some more things out.

Ugh! So Ford is now telling me it's the PCM. They want $1100 (canadian) for the diagnostic (3.5hrs) and then the install and parts ($500 for the part and $280'ish for the labour).
I am interested in wether a used PCM is an option, or if it's better to get the new unit. Any thoughts?
Thanks!

Used PCM's are OK - I still question if that's really the problem.
Make them a deal - if it doesn't fix it, you ain't payin' for it.
Tell them you want the old one too...
The reason I question if it's really the PCM is: Usually, when a sensor input burns out, it doesn't read ANYTHING from the sensor anymore, or reads way out and stays that way with or without the sensor connected. In your case, the computer still sees the sensor, otherwise it wouldn't start without the sensor connected.
But I could be wrong.
How many miles on the truck, what year is it, etc?
Here's a good one: Is it emissions related? As in, hey, the thing won't pass an emissions test, right? Check engine light's on? Maybe they can cover it under the emissions warranty (if you have that sort of thing in Canada).

Hmm, well they said that they disconnected the sensor and then it started up perfectly. That's weird...
When my regular mechanic replaced the sensor, it was reading -10f when it was 80+f in the shop. So, with the sensor reading, but so far out of range, what might cause that?
I'll definitely try to make the deal with them though, since it's a big *ss bill I'll be stuck with.
FYI it's a 2001 with just under 112k miles on it. It had a tune up etc. at 100k and from all other accounts seems to be in great shape for the miles on it. The VIN search said it was a Ford fleet vehicle. I don't know whether that means that Ford upkept it well, or beat the tar out of it while it was in their posession.
Thanks again for all your input!

When ever you ger weird and un expected test results always always suspect voltage and grounds. Start at the battery. Lots of posibilities for grounds to get corroded and there are dozens of them. Happy hunting!
