Started my truck yesterday and a low tire warning came up. Outside rear wheel on right side of my dually said 41 lbs. Pressure. Sure enough when I checked it that's what it measured. Thought I ran over something. Went to get it fixed and tire guy came back and said the sensor was leaking where the rubber meet the metal. He showed me the part. He's seen several. He put an all rubber replacement on. Cost of $26 total.
I called the dealer she I bought the truck. She checked with service and said it hardly ever happens. She said in the future to come to Ford as it is under warranty. The tire guy did all six sensors will eventually fail. A pain in the butt to go 1 by 1 to Ford dealer.
Haven't I seen a similar report here somewhere? The tire sensor going out?
Yes. The aluminum rims corrode because of the steel stem. Be sure and spray your rubber valves to make sure they are not leaking. Sometimes the rim is so corroded the rubber can’t seal. Then you need new rims like me. Unfortunately they are on backorder because this is a widespread problem.
Took my 17 F350 in dealer replaced all sensors with rubber ones. Two were leaking down Rims were fine Said he might as well replace them all rather than have me keep coming back Smart dealer

I'll wait till next one goes out then cross that bridge. Truck has 8500 miles on it
One of mine was starting to leak real bad. Dealer giving me the run around. Parts on back order.
Went to Discount Tire today, they replaced the stem with an aluminum one. TPMS working fine, no more leak.
NO CHARGE!
Will get the others done when I get new tires in the fall.
I wonder what has changed.
Ford has used the same size dually wheels for years.
Different manufacture of wheels?
But the wheels are made to the same print I would think.
Was it the addition of the TPMS sensors?
Aluminum change?
If the inner and outer wheels are doing the same thing, then it has to be the TPMS sensors since the inner is steel and the outer is Aluminum.
I just had all 6 stems replaced. The parts they used were FR3Z-1700-C. The original ones leaked constantly, about 5lbs per week. These are holding better, but we'll see.
The ones they replaced them with are the same as the ones you had. They are the OEM valve stem and will continue to corrode and leak in the future. Ford needs to find a replacement stem to correct the problem.
