TPMS system not working????

[13RamExpress]

I found a nail in my tire this evening and will fix in the morning.

But my TPMS light came on and now the center display doesn't read any of the 4 tire pressures???

When I start the truck, the TPMS light flashes for about 10 seconds and than stays on.

Any ideas guys? Truck only has 14k miles on it.

How long has the light been on? Did it just start acting up? What does it display instead of the pressure? Just little lines? I would fix the bad tire and make sure they are all at spec before you try and diagnose another problem.

Just came on when I left work, was fine when I parked it, than 5 hrs later when I left it came on. Yeah just displays little lines

If it just has the little lines and doesn't read any pressures, it is typically a problem with the module that received the signals from the sensors. Tpm module, wcm or whatever you have on yours. It might just be a coincidence that you found a nail.

I put on new wheels and tires. They already had TPMS sensors in them, so I left them together and was going to get them flashed to read on the truck. Only thing is, 3,000 miles later, and still no warning lights, so I am going to just leave it old school (where I would rather have it anyway!).

Mine has done the same thing as the OP a couple times. First time it went off before I was able to take it into the dealer and everything went back to normal. Second time I cleared it by unhooking the battery for a little bit.
Everything is normal since.
I'm going to try to get it into the dealer for some small warranty stuff when it's on next time.

Gunner, there's no warning light because Chrysler vehicles self learn their sensors. You don't have to scan them into the TPMS system like others.
