Local company sells new takeoff OEM wheel/tire sets with TPMS sensors that were by removed from '22 F150s. Can I just install them on my truck (2019) and go, or will they require relearning/remapping with a tool? TIA
As long as the frequency (and for correct year F-150) is correct, it should learn the new sensors once the old ones are removed from the proximity of the truck. Mine picked up the new sensors automatically.
On my 20 I made sure and did the relearn which is stupid simple. Consisted of putting the vehicle in learn mode and letting air out of the tire till it sensed it then moving clockwise around the truck till done.
I bought these wheels/tires as new takeoffs for $1,000 tps sensors included with free shipping. They bolted right up to my `15 KR & the sensors worked from the get go. I did have one go bad about 6 months later, but my mechanic replaced it for me for a fee.
When it comes to TPMS, my understanding is that they are very vehicle specific and frequency may varies from models (trims) and model year.
TPMS frequency hasn't varied on F-150 trucks in North America, ever. They are all 315 MHz.
Every TPMS OEM (Ford is not a TPMS OEM, be sure you understand the meaning of OEM as it is not that which is used in the popular vernacular) speaks a unique protocol. If your sensor does not speak the protocol your vehicle understands then you are S.O.L.
What does happen among F-150 wheels is that each sensor has an ESN (Electronic Serial Number). This number needs to be registered (paired) with the vehicle so when it hears a TPMS broadcast the vehicle knows it belongs to one of it's tires.
Sometimes the vehicle is able to guess that it's old TPMS sensors are missing and new are present. There are switch dances one can perform from the driver's seat to aid this learning. Is far more reliable and quicker to plug a TPMS scan tool into the OBD port and write the ESNs directly into the vehicle.
On my 20 I made sure and did the relearn which is stupid simple. Consisted of putting the vehicle in learn mode and letting air out of the tire till it sensed it then moving clockwise around the truck till done.
TPMS Question: Mount and Go?
