TPMS question for winter wheels
Reading further into the thread, it looks like the more advanced TPMS in our F150s can self train. In my transit it is basically an idiot light to let you know when a tire is low, no way to check the pressures from the dashboard. OTOH, I run higher pressures in the back than the front on the van, I think it would be happy if all the pressures were consistent?
Just swapped my winter wheels on. Purposely put in low air pressure to start. Tires read correctly within 3 miles with no training procedure necessary and no tool was needed.
I bought sensors off of Amazon using the part number for my truck. Arrived in two days and work fine.
I do have to use a tool on an 07 Explorer. This is so much easier!

After further research, there are two different sensors used on 15-18 F150's. 315mhz and 433mhz. According to my build sheet, I have the much less common 433mhz, which would probably explain why the dealer said the TPMS19 tool would not work for me. I also wonder if the truck can be programmed to accept either. Maybe this is why most people report the ability to self learn, where it hasn't worked for a few of us. So, with that being said, it appears there may be slight chance that a used set of wheels with TPMS may not necessarily be compatible with your particular truck or may not self learn. I was trying to figure out what determines which sensor you get, but I haven't been able to find enough people with the 433 to make any sense of it.

Everything I can find indicates that you are correct, so I am curious why I have 433's. I just tried with my TPMS tool and I have to select the 433 option. It will not communicate on 315.
When I mounted snow tires on the stock wheels on my 2015 I had to use this to get the truck to relearn the new positions on the truck. I also had to use the brake, key cycle 3 times brake method to get it into program mode as the hazard light press method didn't work.

My tag says 39psi front and rear, so my TPMS is set at 30psi OR HIGHER (Ford can set psi above recommended-25%, but not below). As long as I stay above the psi set by Ford, TPMS doesn't care what the actual pressure is. I can run P tires in the front at 39psi and LT tires in the rear at 85psi if I like.

I tried looking up by VIN and other methods in various systems, and couldn't find anything that would list only a single frequency. I happen to know someone with access to a $2K+ TPMS tool, and confirmed that for my September 2018 KC build it used the 315 MHz sensors.
FYI: I ordered a set of those for my winter setup and they auto learned fairly quickly. Not sure of exactly when, but it was under 20 miles on the way into the office.
