Tire pressure monitor problems for 2007 Mustang GT

Does anyone know how to go about programming the computer so the tire pressure monitor light goes off on the dash? After changing the wheels and tires the light came on. The place that changed them didn't realize that the wheels had monitors in them neither did I.I was just about to get all the wheels dismounted and put the monitors in the new wheels and tires.The problem I have is that I read in a magazine that even when you rotate your tires the light will be a problem because of a preset distance from monitor to computer.So I was trying to wait and see if there is anything that can be done about this by some sort of programming.I believe it's a new feature for 2007 mustangs.I may be wrong but at any rate hopefully someone knows of a permenant fix to this problem.Any help greatly appreciated.

I don't think you have to order new sensors. I recently ordered new straps (it's like oversized hose clamps that hold the sensors in place). Sensors aren't the problem. Discount Tires told me to remount them with the new straps. I read online or magazine that you will have a constant problem with the monitors because of preset distance between monitors and the computer. So even rotating the tires when supposed to will set off the dash light. One guy in Texas at a Ford house told me that they could rewire the relays on the computer so the computer would relay to itself not to the monitors. But I am not sure what that would do to factory warranty. I am weary of doing this because the computer is so touchy and not sure what it would do to the car overall.

The 07's are required to have them. I have them in my 07 pony and 07 Chevy. The manual (on my Chevy) instructs you on the reset, but not to disconnect them. Also from what I read, that the tire dealers are suppose to install the sensors on new wheels, (of course at a cost) like 100.00 per tire.

it seems pretty difficult to change tires on the 07 gts, its gonna be tough trying to get rid of this light

Yes in my magazines it says that all passenger car will have to have the monitors in the future like by 2008 or 2009.It just sucks to have a new car with a dash light on already.

I'm worried that even if I change the bands in the tires being the original tires are one pressure and the after market tire are set at another will the light still go off regardless?

The sensors don't read pressure, just wheel rpm.

this is not very well thought-out. i mean its a mustang, not many people are going to be keeping the stock wheels and tires!

anyways, if anyone figures out a good solution, please post

I am also thinking, that a lot of 4x4 off road warriors lower tire pressure for better tire flex and traction, and so does plp during heavly snow covered roads. This will be a pain for them.

ok well after about 4 hours of driving back and forth from dealerships to tire shops i am thoroughly frustrated.

i went to a nice, well known tire shop and they said they could fix the problem and order a new sensor set for around 150. then they told me the sensors actually wouldn't fit the wheels that i have so they would have to band it(?). this "banding" somehow brought the price up from 150-400 and he said around 400-600 for labor!
thats ridiculous

so finally i took it to a dealership, they turned off the light and i don't have sensors or a light, i can live with that. cost me $0.00

there's one solution...

Too bad it had to come to that... But at least the light is off.

tire pressure monitors

I have a 2007 Mustang CT/CS and the only time I had the low pressure tire moniitor come on was when the outside temp. lowered in the winter time I checked the tire pressure in tires was around 28 psi. Once filled and rechecked all ok again. Since then I have rotated the tires with no problems at all with the tire monitor system.

When I got my 07 GT, the light came on every time I started it. Took it to the dealer. Turned out 3 of 4 wheels had no sensors. They installed them under warranty and haven't had a problem since.

I'll look tomorrow when I'm at work and find out more details on the reprogramming of them.
But when rotating they should not need to be reprogrammed. The system in the Mustang does not decipher wheel positions.

Unless they broke a sensor, its not going to help. Did they reinstall them with new straps?

Actually they're not that primitive. The other ones you've dealt with are the most primitive. Those are called indirect TPMS and work off the abs system.

Most likely your new tires will require a higher pressure, assuming they are lower profile. The factory setting will trigger the light on at a 25% loss of air from 32 psi. This can be reprogrammed at the dealer.

100% incorrect.

They should have used the old sensors and purchased the aftermarket bands for them. Much cheaper and easier.

I highly doubt they turned off the light, thats against federal regulations. Maybe they actually corrected the problem?

Its ok to remove the sensors, but to disable the light is where it breaks the law, and I cant see a dealer doing something like that. Pretty much the same thing as them removing your converters.
