Hello everyone. I have done extensive research but can't find a definitive answer to my particular situation. I have a 2017 F250 XLT (gas) that has stock 18" wheels. I recently purchased a set of 20" take-offs from a 2021 F250. The person I purchased from said they have the TPMS sensors in the wheels. I personally put the new tires on.

I have driven approximately 30 highway miles with the new tires and my TPMS readout seems to be showing my stock PSI. I am not receiving any error code. The PSI readout simply stays the same and adjusts slightly when I return home (the stock tires are stored in my shop which is adjacent to where I park the truck).

I have visited a tire shop to attempt to program new sensors to truck. I explained in detail the facts. They seem to trying to do a relearn and not a re-program. Once put in the relearn mode, their tool does not "see" the new sensors and we get the double honk to indicate the relearn process failed. I also visited a Ford dealership and again explained to them in detail the facts. They used a small grey clicker tool while in the relearn mode and again got a double honk to indicate the relearn process failed. The Ford dealer said the only recourse I have is to take the old sensors out of stock tires and install them in the new tires. This sounds ridiculous to me!

So is there a way to get the id's of the new sensors (without demounting the tires) and program/clone them to my truck? I would like to use the new sensors as they are newer. Thanks in advance for the help!

 

Is the sensor frequency the same between the 21 sensors and the original 17's???

 

I thunk both years used 315 Mhz sensors.

 

2017 F250 6.2L here.............

I have 2 sets of Ford rims. One is stock and I purchased a second set of rims w/ Ford/factory TPMS sensors. (I'm using 2 different sets of tires).

-- The first time I changed rims/tires, after about 2-3 miles driving the new set of TPMS sensors was automatically picked up and the new psi's displayed as expected.

-- Each time after this I have either had to use the tool (bought for about $10 on amazon). Or, if for some reason I couldn't get a tire/sensor to work........ I had to take it to a tire shop and have a TPMS sensor replaced..

The first 2 times the TPMS sensors did not automatically relearn, I had one bad sensor. The next time (about 2 weeks ago)............ i took it to a tire shop and they found 2 bad sensors.

Each TPMS sensor has a battery. When the battery runs down the sensor does not work and needs to be replaced. What a joy to be able to read the tire pressure.

I drove 100,000's of miles over 40+ years with no TPMS sensors. Not really much of a problem. I just had to help my wife, son, or others figure out what their problem was all the time and adjust their tire pressure to help get rid of their idiot lights. In fact, this F250 is the first vehicle I have had with TPMS sensors. (Although my wife has had a few). Every time one goes out it cost me about $100 or more if I choose to fix it. My son recently put 4 TPMS sensors inside a PVC pipe container he built and pressured up to about 40psi and threw under the back seat so he wouldn't have to deal with all the warnings and idiot lights. This way he could access them and replace a sensor easily if need without going to the tire shop.

Yes, I get the benefit when they work (especially for all the guys using those wagon wheel rims....... the ones with almost all rim and almost no rubber).

Anyway ......... good luck and hope your issue gets worked out......!!!!!!!!!!!!

 

I think I will try moving my stock tires to my RV storage shed which is several miles away. I believe having them close is affecting things. I still wish there was an easy way to get the id's of the new sensors without demounting the new tires.

 

I have had 4 different ford trucks since 2012 and i used a set of summer wheels and a set of winter wheels on each one and all i have ever done is swap the wheels and drive, usually takes 10-15 miles of continuous driving before the truck picks up the new sensors. You need two things for this to happen, TPMS sensors that match the proper MHZ of the OEM sensors that came on the truck, and sensors that require "no programming required before installation".

You may have a MHZ difference due to the two different year trucks that the wheels came from? Go to rockauto.com and look up sensors for each truck, there website shows the MHZ for that particular model that may be your issue?
