Let's say I don't have the TPMS re-learn tool. If I go into "learn mode" and then don't do anything, what will happen?

My guess is that nothing will happen until you turn the car off. The odometer message center will display that you need to use the tool on the driver's side front wheel, but I don't think it will do anything else.

Not 100% sure, though...

I heard somewhere that a strong magnet works if you don't have the tool. I have never tried it out though.

Yeah, back when I was doing the research for all of this I talked to a few Ford techs and a few from NTB. Only certain types of sensors which use a switch-type reset will be able to use an industrial strength magnet. You can try it, but I have no idea if it will work.

And I took the day off today, so I may try going into relearn mode and not doing anything just to see what happens. I might bring my other wheels nearby to see if it confuses the computer at all. Or if I just annoys the hell out of my neighbors because the horn keeps honking.

Whew. Long time no post on this thread. I never ended up going into relearn mode again because get this...I never needed to. For some reason I expected that my car could only be synced to a single set of TPMS sensors, but that's not the case.

When I put my stock wheels back on with the stock sensors, I never got a TPMS fault. In fact, the idiots that mounted the tires before the alignment never filled the tires with air like I asked, so they were all running at about 26 PSI, thus about 10 miles down the road the "LOW TIRE PRESSURE" warning came on. Pretty nifty.

So the lesson learned is that apparently you can have MORE than one set of TPMS sensors synced to your car, and even if it's 6 months later, your car will recognize them without needing to re-sync! Pretty sweet.

I was at a dealership the other day and they stated that its a Bluetooth connection!
So much like a cell phone it can be synced to multiple TMPS sensors.
Take it with a grain of salt, but that's what they state.

It can't be a bluetooth connection, it doesn't fit within the operating frequency to fit the specification. They are UHF based, as in Ultra High Frequency - the same band as your key-less entry fobs. US TPMS (mostly) uses 315MHz for data transfer.

The simple fact is your car can learn multiple key fobs, just like the TPMS computer - someone put two and two together and assumed it was bluetooth because it acts similar, but is completely different.

Bluetooth uses a radio technology called frequency-hopping spread spectrum, which chops up the data being sent and transmits chunks of it on up to 79 bands (1 MHz each; centered from 2402 to 2480 MHz) in the range 2,400–2,483.5 MHz (allowing for guard bands). This range is in the globally unlicensed Industrial, Scientific and Medical (ISM) 2.4 GHz short-range radio frequency band. It usually performs 800 hops per second, with AFH enabled. [7]

We recently purchased a used 2008 Focus. While driving down the expressway, the tire pressure monitor fault light came on. We checked the tires. All were ok. After restarting the car, the light wasn't on. Came on again about 200 miles later, (on the expressway) stayed on for about 8 minutes and went off. Now the light comes on more frequently when driving around locally. The dealership put 4 new tires on it before we purchased it. We purchased car from a non ford dealership and have called them regarding this warning light, but are reluctant too look at it. Car has been driven less than one month and we have put on less 600 miles. Any suggestions? I have printed out steps about resetting the warning light. After reading several forums, it appears that when the tires were changed the TPM wasn't reset. Is that correct? Therefore falling under the dealerships responsiblity of the tire warranty we have. Before purchase, the car was inspected and drove but the light didn't come on during that time frame (of course!) Any suggestions would be greatly appreciated.
