TPMS quit in one tire

[Louiscypher]

I have 2020 Mojave with aftermarket rims and tires. (I did not put them on, they were there when I bought the Gladiator) I have owned the Jeep for seven months, and not had any problems with the tire pressure monitoring system until today. For some reason the passenger front tire pressure monitor quit working. It’s flashing a warning light on the dash, and shows a dashed line where the tire pressure would be for the passenger front tire. All three of the other tires show the correct tire pressure.
This morning when I started the jeep, the monitoring system was working fine. Drove about 3 miles got out to run an errand and when I got back in and started the jeep that’s when I saw that the passenger front tire pressure monitoring system failed for that tire. The jeep was only turned off for maybe 10 minutes before I got back in. From there, I drove about 8 miles to work and turned it off a second time. It was off approximately eight hours before I started the jeep back up to drive home from work. The drivers front pressure monitoring system was still in a failure mode. Drove it home and turned it off for the night.
Nothing abnormal about the weather or street situations today when I was driving. It was raining this morning, but nothing more than just a normal rain. No downpours or floods or big puddles that I drove through. But on the other hand, I’ve been through snow and rain since I bought it in January and have had no problems up until today.
Any ideas of what might be going on?

A cheap test is swap 2 tires with each other and see if the problem moves with the tire. If the problem moves it's going to be the sensor that's the issue. If the problem stays at the same original location you got a bigger issue related to computers.

If it's a bad sensor it's not a bad idea to swap all at the same time but that's just how I would do things

My first thought would be the battery in the sensor. They could easily be five years, if not older. You can move the tires around and see if the problem follows with the sensor.

I would suggest stopping by a tire shop, or maybe a Sam's Club or a Costco. Get someone to use a scan tool on the sensors and check the battery condition in each one.

He's got a 2020 so it's nearing time to replace em anyways. But if it's an intermittent issue it could be an issue either sending or receiving the signal. Best case is just an issue with the sensor whatever it is.

My TPS monitors on my old Jeep liberty lasted 11 years before replaing them. They were the factory one's. Plus they went with inflated , deflated hundreds of times for beach driving for surf fishing. Replaced them with factory one's and then traded it for my Glad.

Seems like a battery issue. Those batteries either last forever or give up the ghost randomly, had one do just as you described it before. It was like the cold morning gave it enough juice then it would stop reading later in the day. Or let's hope that is all it is and not the reading sensor or computer issue, most likely not but it is a possibility.

Ok. Thanks for the help.
I will rotate the front two. See what that does and then go from there.

Probably one of two things happened.

Either the battery croaked, or the screw/bolt attaching it to the valve stem came out and it bounced around long enough to break it.

If you do have to replace it, save the headache and replace them all.

My Mojave with less than 3000 miles on it had one bad sensor. It would come and go by sometimes providing proper pressure and then throw the check tire pressure error. With aftermarket tires and wheels, I was certain the dealership would laugh if I wanted it replaced under warranty. But I went in today for the first free oil change and they replaced the sensor. It was a good day!

Sounds like a low battery in the sensor, any tire shop should be able to set you up with a replacement. They will be able to scan the sensor and check the signal, you might try re-pairing it with the truck and see if that works; every time I've had an intermittent TPMS failure it's been a low battery.
Discount Tire will usually check it for you for free.
