I assume the batteries went dead or something, but wanted to check here first. I swap winter/summer tires every year. I have a 2017 purchased in October of '17. Each set has their own rims. I just put my summer tires back on, which are on the original rims with original TPMS sensors that were changed 2 summers ago. About 20 miles into a trip, my TPMS sensor went off so I pulled over and checked tires and they were all holding 35 PSI like they were when I put them on the night before. the digital gauge on the cluster just shows -- for each tire so wasn't sure if it was a problem with my truck or the sensors.

anyway, felt comfortable just continuing on our 6+ hour trip and had no issues. When we got home I was parked close to winter tires I had taken off and it must recognize those when parked next to them overnight, because the past 2 days when I start it, there is no TPMS warning and it trips about 15 minutes into our trip to take the kids to school.

So I'm pretty confident it's a sensor in the tire issue. My questions are, #1 if one sensor goes bad, do they all read -- on the cluster gauge? Or is there something else I need to check? Seems like a pretty short time for them to go bad with this only being heading into the 3rd summer with them.

Thanks

 

If one sensor is bad, the others will still read. If you go to the screen that has the tire pressures, you should see all 4. If one of them is not showing up, that is the bad one.

 

hmm, none of them show up on that screen just -- where the pressure should be shown.

I just went and checked with it parked in the garage with the snow tires I just removed sitting next to the truck and it is reading those and showing 35 in 2 tires and 36 in the other 2. so it is reading one set, but not the other. If I go for a 15-20 min drive the sensor will go off again and read -- They were all fine when I took them off in December and swapped them and the sensors are like I said only going into season 3 so i can't believe they all just took a crap, did they?

 

You may need to move the snow tires away from your parking spot. I used to swap tires/wheel like you, and it would usually "find" the new tires after 20 miles or so. Perhaps it's still trying to read the snow tires because they are near the truck when it's started? You may have to train the tpms sensors manually, but that requires a tool.

 

I guess I'll have to take it somewhere and have it done. We were gone from our house from Wed till Sunday last week and the TPMS just stayed on the entire time after about 20 min of driving after the switch. So it's been parked and away from the snow's for a few days.

I just noticed that when we got back and took to the kids to school yesterday and today that the TPMS was off when leaving, but after 15 min or so of driving, would go off again. So when I got home today I checked dash gauge after it was in the garage for a while and it was reading the snows.

Thank you for your help

 

Please post the outcome, very odd situation. Any other odd electrical issues? Are you still on the original truck battery?

 

I’ve had 4 13th gens and about 16+ wheel/tires with only one tpms issue.

When I went to sell my 2020, I took the venomrex off and got some stock take offs. I thought the truck learned the new wheels/tires as everything was fine for a few days on short trips. One day, I went on a longer trip and 15 min in, all 4 sensors went blank.

did a lot of reading on forums and Facebook and someone asked if my old wheels/tires were near the truck…which they were. They suggested move them away so I put them on the backside of my property. Sure enough, the next day, started the truck and it read all blanks. Went for a long drive (20 min) and the truck finally picked up the new sensors…so all good.

ive always been told that the wheels/tires need to be in motion for the truck to link to them so not sure why my truck was “reading” the old wheels/tires but it fixed it when I moved them away.

never had an issue with the truck learning any new sensors, normally just takes 15-20 min driving for it to swap over. Just recently swapped raptor take offs, to methods, and back to raptors without any issue and they were different pressures so it picked up the new set every time.

so I would make sure the old set is far away….and as already mentioned, if one sensor goes bad, the other three would read. Never seen 4 sensors randomly go bad…normally it’s something else .

 

I'm on my third or fourth vehicle with TPMS, and I've never seen the display go blank on any of them that could display it. Even if the truck's been parked a week, when I get in and start it up, I can go to the TPMS screen and all the tires will display their current (or at least recent) pressure. FordPass is the same - check it while the truck is parked and it will display pressures. I don't know the specifics, but this leads me to believe that the wheels need to be rotating to give you a "real time" pressure reading, but when they're not rotating, the sensors go into a "parking mode" that sends a periodic pressure reading at much greater intervals to save the battery.

I've had a couple sensors fail, but never earlier than 5 or 6 years of service life. I'd think they would last longer on wheels that aren't used all year.

 

id tend to agree…I guess I could just go let 5-10psi out and check my FordPass in the morning, lol.

ive even let 5psi out and rotated my tires to see if it moves so I guess I’ve got nothing better to do

 

No other issues other than the frozen locks, IWE early on and the cam phasers of course LOL. But nothing else electrical.

It is odd, I was away from the old tires for 6 days, a state away, but same issue. after parking in the garage again at home if I only go for a 15 minute or so drive and shut if off, it still reads the winter tires from garage. and back home, stays good still. 20-25 minute drive, TPMS goes off again.

I do still have original battery in the truck. But the fact it reads the winters just fine, but not my summers that were fine when I took them off is strange they'd all go out.
