TPMS issues

[Candoman]

Anybody experience this, almost daily notification from Ford Pass that I have tire pressure problem but no indication on dash that there’s an issue?
Tire pressures always check out good at 35psi.
Is there an easy check to see if each individual tpms sensor is good or am I stuck with the dealer, just thought I’d ask before I go to the dealer. Thanks Ken

Go to the Tire Pressure display in the instrument cluster's INFORMATION screens. There are multiple screens in that INFORMATION section - one is Tire Pressure and another one is remaining Oil Life.

The tire pressure screen should look similar to this one:

Thanks for the info, I checked it out there were 3 at 35 and 1 at 34?
I didn’t think they would be that sensative?
Still don't understand why it doesn’t show up on the dash just on my phone, unless there’s a set limit under/over that triggers the dash warning? Thanks for sharing, ken

In my 2022 hybrid XLT I do not have Ford pass on phone but when my tpms dash light lit up it was at 26 lbs! I was expecting about 30, don't know why.
ETA: I checked manual. The dash light comes on when "Tire Pressure is significantly low" without stating the trigger point. Most likely setting accessable with forscan? I do notice that tire pressure can vary 3 or more pounds just by ambient temp changes as well as highway driving.

They aren't that sensitive (when deciding to show a TPMS error). I think the threshold for them are in the 20's for a tire it thinks should be in the mid 30's. I know I have had mine closer to 29/30'ish (middle of winter, in the morning before driving) and did not get a warning.

What does it show in the app?

I had 1 sensor recently that would randomly show offline. Dealer ended up replacing 2 of them under warranty. No issues since.

ForScan can change the set point for the TPMS system.

If you have the small little clicker tool, you can go through the steps to force relearn each sensor to see if one is bad.

The system is not that sensitive. I have had pressures from 30 to 45 with no warnings.

If you are within 1 psi of the recommended pressure, something else is definitely going on.

As several have stated not that sensitive nor accurate actually. May luck out, but may not.

And it doesn't alert when so far away from recommended 35, but when a sensor isn't reading or 1 far enough off from the others.

So slightly before you get your alert, either of those must have happened and truck reported it up.
But by the time you look at dash it's gone.

So next time while in app go to screen to show individual tires and see which one it is.
Then to dealer with screen shot.

Do you have another wheel set in your garage (winter/summer tires)? If your installer copied the TPMS sensors from your factory sensors vs. just programming them, your truck could be picking up from the other wheel set.

I do and they will be going on the truck probably in a few weeks as the white stuff is coming soon but this problem only just started about 2 weeks ago so?
Thanks everyone for your input I’ll post when I find the solution.

Just for kicks - check/set the air pressure on your other wheel set, or just separate them from the truck by more distance, and see what happens. In my case, I hadn't even installed the TPMS sensors in my other wheel set I had just copied the programming. But having them in their boxes in the garage was enough to cause interference. I went back and "programmed" them instead of "copying" and no more issues.

I have my own TPMS programmer, but if you don't, your installer should be able to fix that in about 5 minutes -- if this ends up being the issue.

which tool is this?

On mine the trigger seemed to be 30 psi. Under that it alerts
