TPMS problem

[gdm32570]

I have a 2024 Maverick. With the colder weather we have had the tpms light came on. I inflated all tires to recommended pressure and drove it down the road, but light is still on. Is there a way to reset the system?

Greg,
Is there a way for you to reset it?
I don't think so. Not without a special tool.
Good news is.
Your sensor did NOT fail. That statement I'm pretty confident in.
It's the computer in the truck.
Here are my examples from last year from yesterday and today.

Yes but today it's the driver side rear and the passenger side is okay. See my post #6
Today's went away while I was driving.
Here's the picture.

A couple of weeks ago it was the other side.

Pictures from yesterday show both rear sensors out.
Please note the mileage.

One sensor comes back.

Today, cold tires pulled the truck out of the garage and drove it to take the picture. Everything is fine.
Folks it's not the sensor it's the computer.

You would need a TPMS tool to try to retrain the sensors
Most likely one of them has failed if the pressures are correct
Cab you see the pressures on the dash?

I've been playing with this since the truck has had 18,000 miles on it.

I can see the presures, they are with 1 lb of each other

Cold tire pressures are exactly the same.
The tire pressures change as the truck is driven or the tire sits in the Sun. Which is perfectly normal and can be expected.

I drove it down the road for about 20 minutes at 45 mph. The pressure in each tire is where it's supposed to be, but light is still on

Can you take a picture of your dash? Such as I did.
So we can take a look at what's going on.

Thank you very much.
That one picture, tells the story. 30 & 31 psi warm tires
I can tell you right now. The reason tire pressure light is on is because all your tires are low.
You need to add air to all your tires while they are cold. Tire pressures for my truck are 35 psi. I purposely set them to 34 psi cold.
I know for a fact that once my truck is moving the tire pressure will increase.

I have found tire pressure gauges to be wildly off on indicated pressures. I now use.

Here is my collection of gauges what I've started to use on a regular basis is the Stanley jump pack/ compressor it works the best for me. It gives me accurate tire pressures in each of my tires and shuts off automatically when it reaches that pressure.

Been posted before. Must drive truck (some were saying maybe about 20 minutes for verifying which tire is on which position. After twenty minutes drive around block so it can figure out by counting number of revolutions (the outside tire turns at faster rpm). It figures out the front tires first first. True or not I haven't confirmed. The tpms batteries are supposed to last 10 years or 125k miles whichever I occurs first also!
ETA: If the wheels are not rotated for 15-20 minutes the Tpms turn off to save their batteries!!!

So you are getting a reading from each tire.
And there is NOT a low one in the group.

You have a stuck error, perhaps when it thought there was an issue.

How to get unstuck when it already sees all the tires and good pressures?
Still under warranty?

Have a scan OBD tool?
Have a wrench?

Forscan Lite has a TPMS module reset - probably would get rid of error.
If not - disconnecting the negative battery terminal for a few minutes might be similar.
Either is quicker than dealer, if possible to do first.

Going to try the battery disconnect tomorrow, thanks

Mike,
Wouldn't a warm tire pressures of 30 and 31 be considered low?
Wouldn't that put his cold tire pressure around 26-28 psi ?
