So I've recently bought a set of wheels+tires (with TPMS) for my wife's Ford Mustang Mach-E. It was the winter setup. They arrived, I've mounted them, and everything worked just fine, TPMS and all.
A month ago, I've purchased a set of wheels/tires with TPMS for my 2018 Expedition MAX. This was going to be my new summer setup as the old wheels were curbed to death (wife parallel parking). I put on the wheels, and after driving for 10 minutes get a TPMS fault. Something about Tire Pressure Monitoring Error on the dash.
Tire rack says they're the correct type, but might need to be programmed.
Local tire shop tried using their Ford tool to program them - no luck.
I tried following the backdoor approach (from the manual), where you turn ignition into full accessory mode, then turn the hazards on/off 3 times, and that enters the "TPMS learning mode". Once you're in that mode, releasing air from each tire should cause the TPMS to transmit a low pressure signal, which (in theory, I'm guessing), the vehicle picks up and learns.
That approach didn't work either. I just keep getting two honks that the learning was unsuccessful.
So Tire Rack decides to send me another set of TPMS sensors, saying the old ones might have had old batteries (great).
I pay - out of pocket - to have the tires dismounted, TPMS sensors swapped with the "new" ones from Tire Rack, and then have the tires re-mounted and wheels balanced.
No luck. Same TPMS problem. Tire Shop can't program them, and backdoor method still doesn't work.
If anyone has any ideas about where to go from here, I'd certainly appreciate it.
I know if I take this to the dealer, they'll insist on dismounting the tires, and installing OEM TPMS sensors. That approach is already looking like a $500 bill.
Tire Rack isn't really stepping up to the plate here at this point.
We have a 2,000 mile road trip coming up next month and I'd love to get this sorted out. Thanks a million for anyone that can offer any insight into this!
