FYI, after a quick look at Tasca parts it shows both 315 Mhz and 433 Mhz for a 2017 Ford Raptor. Seems strange they would use two different sensors types, but there it is. I really wonder if @Firedaniel is on to something with the Forscan setting.
I can’t prove it as the tires I had didn’t have the sensor. But they wouldn’t pair until I changed the settings in forscan back. Good luck.

Well, decided to order some TPMS sensors at the 315 Mhz. Went with a supplier on Ebay that has OEM takeoffs ($55 for Q=4) rather then get generic new ones. They should show up next week and hopefully I can get them on sooner after. Also, my tire light is still on, so either I don't have sensors or I have the wrong frequency of sensor.

@buzzin 1/2 dozen Thanks for the comment. It appears on the website that either could come on the rims from the Raptor. The standard F150 only has the lower Htz offering shown.

@buzzin 1/2 dozen Ah i see now. Hmm, well that makes it all even more interesting. Guess I'll find out more once I get the new sensors put in to see if indeed the Raptor rims/tires do have sensors or not that I got.

@OEWheels-Tech I have Ford Raptor takeoff's, so while they are OEM, they are different from my stock 20" wheels. And yes they are taller/wider than my factory 20's.
Having different size tires and/or tire pressures than specified on the OE placard in the door jam. Your TPMs light will come on if the tire pressures are low, as well as, when over-inflated. In other words, your TPMs sensors may actually be working and your tires may be over-inflated (according to your TPMs sensor). The light may come on because of the parameters the tpms sensors were program to the OEM tire. For example, the tpms sensor was programmed to turn on the light if the tire are below 25 psi or if the tire is above 45psi.
I would check you placard to see what your tires psi should be. Also a side note, your tire pressure can go up when you drive, that is probably why your light did not come on right away, until your tire heated up and rose the psi to over the parameters.
