TPMS 315 mhz
Good Evening All. I decided to take the factor Hankook 275 55 R20's off and go with 18" fuel rims with some BFG KO2 285 65 R18 Rubber. Drove it home from the tire shop and the TPMS system started to flash and displayed "--" for all tire pressures.
Took it back today and was told that the sensors were the wrong frequency (315MHz that came with the rims) and was told I need 415MHz sensors. Changed out the one sensor on the drivers side front (as per the 'sensor training procedure' ), drained the air for 15 seconds, and no horn chirp.
Took the truck for a drive around the block and suddenly the driver side front tire and passenger rear tire is recording correct tire pressures while the passenger front tire and driver side rear tire still read "--"
So a few questions for members here that have done the swap to aftermarket rims:
1. What is the CORRECT frequency of tire pressure sensors for 2017 F-150 models
2. Do ALL sensors need to be changed entirely before performing the 'training procedure'?
3. Is the entire training procedure for these sensors best left to the dealer, because I don't think the tire shop knows what they are doing...???

The new NA standard is 315 MHz for primary vehicle and 433 MHz for trailer. Some EU vehicles still come with 433 MHz which is the EU standard.

But…contrary to logic, not all genuine FoMoCo 315MHz sensors are the same. I’m fighting with this compatibility conundrum as well. The “full-length” p/n for TPMS35 sensors is F2GT-1A180-A? (Where the last character evolves over time) These are stamped 315MHz. And online, if you look up TPMS35, you will discover that the TPMS35 p/n supersedes (or is the same as) the F2GT-1A180-A? p/n. But wait - here comes HC3T-1A180-AB. These are also stamped 315MHz! But I’ll bet the truck doesn’t like them!
It’s annoying.

Ford part numbers use a 4 character prefix:
F = Design Year Code - 2015 (often first year of actual use)
2G = Product Line Code - U263 Lincoln (first product line part used on)
T = Design Responsibility Code - Electric Research & Vehicle Tech Operations
Z = Ford Customer Service Department
You really need access to the Ford parts computer system to keep up with all the part numbers.

Well…many, MANY dollars (and hours) later, I finally solved my problem. I had been misled by the tire shop for a period of months paying to have sensors changed, but I was still getting at least two & sometimes three incorrect or missing p.s.i. numbers. And the tech was using a fancy/expensive programmer to “stimulate” the sensors to pair (or ping or whatever) with no success. It was expensive and infuriating.
But I learned that there are two different ways to place the BCM into TRAINING MODE, and he had been using the wrong one the whole time...or--sometimes--not using TRAINING MODE at all.
I re-ordered the little $20 grey fob and did the job in my driveway in less than 2 minutes. With the same sensors in the same tires in the same positions at the same pressures that had been acting up the whole time. How?
Instead of the six presses of the hazard switch, I used the key in conjunction with the accel pedal to enter TRAINING MODE and then jumped out with my little gizmo and pinged each sensor in turn. Done.

Hi Ronemca, can you tell me more about the $20 grey fob you reference?
I've had my truck back to Mavis tire 6 times and they gave up and told me to take it to Ford. TPMS worked fine before I regrettably had the tires replaced at Mavis. The sensors will program and TPMS system works for about a day then it drops right front no matter which wheel is installed there. The truck has a wireless air-lift but it had that system without interference prior to the new tires.
I'm having a difficult time understanding this. 3 sensors are factory, one they have replaced twice now. It's always RF that fails, no matter where the new sensor is located.
