because i am going to have multiple wheel/tire combos, and i dont feel like having it reset each time i switch them. i check my tire pressure weekly, so i dont really feel like the tpms is doing me any good anyways

why not just buy the sensors and bands, then all you have to do is drive around at 15 mph for a minute or 2 and it resets itself, not that difficult and i imagine ford probably runs the tpms fuse through something a bit more important to prevent people from doing such an activity.

You can not disable the tpms system. Mandated by federal law, huge fines if someone tries to disable it. They will take away your firstborn child and send you to labor camps for 3000 years. I am sure there is a way to keep the light from comming on by cutting the signal wire or something to that effect but there is no way to "turn it off".

yeah...i looked and couldnt find an actual fuse just for that...hmm. oh well. just more money to spend i guess
From the 08' Ford Fous Workshop Manual:
The tire pressure monitoring system (TPMS) monitors the air pressure of all 4 road tires. The wheel-mounted tire pressure sensors transmit via radio frequency signals, to the smart junction box (SJB). TPMS functionality is integral to the SJB. These transmissions are sent approximately every 60 seconds when the vehicle speed exceeds 32 km/h (20 mph). The TPMS function compares each tire pressure sensor transmission against a low-pressure limit. If it has been determined that the tire pressure has fallen below this limit, the SJB communicates this on the vehicle communication bus to the instrument cluster. The instrument cluster then illuminates the TPMS indicator and displays the appropriate message(s) in the message center (if equipped).

And yet another asinine, inane government intrusion into our already overly complicated lives just to allow people too damn dumb to operate a vehicle to live long enough to breed even more idiots. Hate this shit.

TPMS is such a retarded thing.
"why would you want to disable it, it tells you if your tires are low"
Seriously? OH MY GOD how on earth did we survive in this world before TPMS was a thing?!?!!?!
Such an annoying light, up here in winter it's such a pain, Start the vehicle, says their low. Nope, they aint. few miles of highway driving, tires heat up, light goes out. Freaking annoying. I look at my tires, I check it's pressure. I don't need no stupid light to tell me anything

As I said, an asinine system forced on us by government wonks who's sole purpose is to allow idiots too stupid to operate a motor vehicle to live long enough to breed more idiots so we need even more regulations.[rant][rant][rant][rant]

I can buy an after-party TPMS system that has valve cap sensors and a cigarette lighter plugin receiver/display for $75, which is cheaper than just one Ford wheel sensor and the cost of having it replaced. So why pay all the extra money for inside the tire sensors when there is a more user friendly product available, and you don't have the chime going off or that warning light always on????
Because that aftermarket system doesn't disable the Ford system, so you still will have the warning lights. I wouldn't trust the caps not to leak either, that's now how valve stems were designed to be used. Okay for cars that don't have TPMS at all and you want real-time readouts, but a poor option for cars that have integrated TPMS.
You can get a set of 4 takeoff new Ford TPMS sensors on eBay for $50. Don't buy them new from the dealer.

The Ford TPMS frequency is 315 MHZ and the aftermarket ones are at 433, which is used by some other TPMS units. I would like the see an aftermarket that would be a cap style that could be used instead of the inside-the-tire. It's -20something right now and changing the TPMS sensor right now is a big headache, were just screwing on a new valve cap is simple, and I could have them on both my summer and winter tires
