Ok, so I've never really had to deal with TPMS before, but after the last few days of reading up on how to get my truck to detect the correct tires, and getting the TPMS19 tool, I still can't get my 2015 XLT 300A truck with brand new Raptor take-off wheels and tires to learn which tires go where. After driving my truck for a bit, I see that it detected the tires for the tire pressure monitoring, but it hasn't paired the correct tire position. I've started the program/relearn procedures, and when it tells me to go to the left front tire, using the air-release method and using the TPMS19 tool, the truck doesn't recognize it, doesn't honk the horn, and I can't proceed to the next tire.

Has anyone had this problem? What am I doing wrong here? I believe I have followed all of the methods to a T without success.

EDIT: I tried starting with each of the other wheels, thinking that maybe the TPMS sensor in the left front tire is bad, but none of the wheels triggered the computer. ALSO, I noticed that my truck is NOT reckognizing my TPMS sensors like I though.. In fact, the TPMS display on the dash is showing the values of my old tires still, and I thought they were the new ones. My old tires were filled to 42 PSI, and these 315's are filled to 35, but the computer still shows 42-43, and the values didn't deviate any after a 20 minute drive.

 

I had that issue when I bought 4 new OEM sensors and one was a dud.

 

Interesting. I thought it may be bad, but the truck detects 4 tires, it just doesn't know which tire is in the appropriate physical location on the truck. I'll try the process again, triggering the right-front when it asks for left-front to see if it'll detect that TPMS sensor. Also, the wheels are only a few months old. I know it's possible for one to be bad, but unlikely I'd think.

 

I replaced my OEM 2015 wheels with a set of 2017 limited wheels that came with TPMS.

Had to drive about 30 minutes or so, but they were finally just automatically recognized and replaced my original TPMS readings.

Pretty sure they’re in the correct location as well.

I think the truck just has magic to do it, but definitely go out for a good drive, perhaps makings errands and such (so truck turns on/off), to see if it corrects itself.

 

No tool is needed. Assuming the new wheels actually have sensors in them, driving is all that is needed.

If all 4 sensors are good they should learn on their own just by driving the truck.

Once when I got some tires mounted the shop messed up one of my sensors and they didn't have another. They mounted my tires and left the driver side rear sensor out and had me drive to the local Ford dealer to get another sensor. It was strange how my dash showed readings for 3 tires but it showed a reading for the driver side rear tire that didn't have a sensor and didn't show any psi for the passenger side rear tire.

 

First we'll assume your new Raptor wheels have good working sensors installed. If the pressures are all good, I would keep driving and hopefully it will reset. It's a computer and they seem to have minds of their own.

I swap my winter/summer wheels in my garage. All have Ford OEM sensors. I've done this several times and usually no problem. However the last time, the TPMS light came on and the computer wouldn't link up the new set, even after driving for several hours. The following day, I was going to check it out further, but magically everything was OK. It just needed a little extra time.

Edit...........the set not in use are stored in a different shed 50-60' away

 

Are your old tires/TPMS sensors still within range of the truck?

 

Yeah, they're in the garage about 15 feet from the truck. and I don't have any other place to put them at the moment. I took the truck for a long drive, and the truck never detected the tire pressure of the Raptors. What's odd, is that when I put the new wheels on, the pressures in the truck read "---", but then magically went back to 42-43 PSI after a drive with the new wheels. I thought it started detecting the Raptors, but the PSI was just too far off (35 in the Raptors, versus 42-43 in the old). I've since lowered the pressure some in the tires, and the readings still don't budge.

I'm really curious why the hell the Ford methods for relearn/reprogram just aren't working. I tried doing them both while I went to the store in the next town over (being really far from the original wheels and TPMS sensors), and the tool wouldn't work there either.

 

I think there are 2 different frequencies. What year are the Raptor wheels? You might need to get new sensors and/or swap your old sensors into the new wheels.
