My 2004 came with a full-size spare, but it had no TPMS sensor. I wanted to use 5-tire rotation, so bought a sensor, mounted it in the wheel having none, programmed the new sensor using a magnet resembling that of a microwave oven magnetron. All 5 wheels now reflect whether air pressure is acceptable of not. Rotating tires has NO EFFECT on the TPMS; no "relearning" is needed. Only a new, replacement sensor requires programming, one time.
The positions do need to be relearned. Press the start button to activate accessory power, then turn the 4 way flashers on and off 3 times. This will enable relearning. You need a trigger tool to activate the sensors or you can raise or lower air pressure in each tire until the horn beeps. You start with LF tire then move to RF, RR, and finally LR. It should then say training complete on the instrument cluster.
This is correct, they do NOT need to relearned.
I would consider having to drive a few miles for the new locations to be picked up, a "relearn process".
Yes it does relearn very quickly…
We have a 16 sport, 18 platinum and nex-gen 2020 platinum in our family. All reset themselves!!! I know this because we do our own maintenance. I pull 5psi out of the left front and when criss-crossed back to right rear, I can follow the psi pointing to that tire in the rear for verification. I’ve always used this procedure before calibrating all four tires with perfect psi. I’ve never had to move the vehicle(s) to reset. Just the time it takes to run the engine after an oil change and check the dipstick, the TPMS resets! (I rotate and oil change simultaneously…every 5,000 miles).
Do you use the TPMS from your vehicle computer to set your tire pressure? Your owners manual SPECIFICALLY says NOT to. Your owners manual will tell you to check your tire pressure with a gauge.
I set tire pressure religiously with my regularly calibrated snap-on digital guage! I’m a motorcyclist; iron butt super bike distance rider so tire pressure is one of those many pre-flight checks set in my noggin’. I’m impressed at just how accurate the ford TPMS readings mimic my snap-on from my shop!
Interesting, my 2016 Sport and 2018 Edge automatically reset without using a tool. Guess my cars are magical....
Manufacturers such as M-B and Chrysler use transponders mounted in the wheel wells to automatically pick up tire position. Ford and GM do not use such a system. Only other way a vehicle could determine position without relearn is if they used indirect TPMS (wheel speed sensor input) measuring tire runout.Interesting, my 2016 Sport and 2018 Edge automatically reset without using a tool.

buy good air gauge don't depend on government designed safety gear
This thread doesn't have anything to do with tire pressures but everything to do about knowing where each specific sensor is located to get the proper readings in the onboard display.
