I purchased one of the last 09 Mustang GTs and recently bought a set of AR/Shelby Razor 20x9 and will be swapping them on before I retire my factory 18" polished 5-spokes.
A friend at Ford ran my VIN and suspects mid-year 2009 Ford switched from the TPMS sensor and bands to a valve-stem TPMS sensor that is being used in 2010+.
Has anyone encountered this? Regardless of bands or the valve type, any experience in knowing if they are compatible?
I've also heard conflicts on if a "programmer" is needed or if the sensors automatically sync after driving with them.
I just want to get the right parts and would prefer a valve stem mounted sensor then dealing with bands. I don't want to have to dismount/rebalance my existing wheels or the new wheels with the new tires.
As far as a programmer, it appears Ford has a couple of part numbers for the fob style ones that run around $35-$65. Do all the p/n work with the cars or I need to watch out? Dealer said since it's electrical, it's non-returnable.
In the shops, they use a much larger and expensive system or wand by Rotunda as I recall.
I bought a set of factory rims that the previous owner left the TPMS on. When I mounted them they tripped the monitor light and I had Tire Discounter program them for $20. It'll cost you more if they have to break down your old tires to get the sensors. It might be cheaper to buy a set off Ebay. The band type are much cheaper than the stem type. I rode around for a few months with the light on, just hit the reset button and it goes off, but I like not having to do that. It was worth $20 to get rid of it.

Just look at your valve stem... Probably a band though. And no, they aren't compatible.
Do you think from the valve stem visible with the tire mounted you can determine if they are the sensor type or not? The problem I have is knowing what my factory type is (ie. band or stem type sensor).
From what it sounds, the two different types aren't compatible. I'm hoping to clarify if there is a way to confirm my system without dismounting a tire from it's wheel.
I'm not confident Ford is telling me the right info based on my VIN alone, since I find no confirmed source of a valve sensor on any 09 Stangs.
You can tell by looking at the valve stem. It's tricky though.
This is what a valve sensor looks like on a newer mustang
this is what a regular valve looks like.
if u have the second one you have band sensors. Study the pic and it will be easy to tell the differance. A sensor valve will be really stiff vs a regular valve which will move pretty easy. Hope this helps.
