2024 Power Wagon, TPMS light care on yesterday. Stopped checked all tires and are all right on. Came out this morning and that message is still up there. Any ideas?
 
Good luck. I have had this happen 4 or 5 times even had a message from Ram pop up on the 12" radio screen. Have been to the dealer 3 times and they find nothing wrong. Asked if they could lower the air PSI level so this would stop. They say they cannot do that. I found if you go to some one or buy the software with j scan you can then change the PSI setting. I am afraid that some time it may be real and I ignore it and wreck the tire or pull over to check the tire and somebody rear ends me. I feel for you. There are other places on this forums that talk about this problem.

check,

Thank you for your reply. I have made an appointment for the morning with the dealership. I drove for a long time before TPMS was invented. I am annoyed, but I am traveling all over the country. I will do what I have to do.

Thank you again for your story, it may help in my dealings with RAM.
 
My 2019 never did it until a few months ago. It would read pressures, but would randomly give that message with the tpms light on and it would randomly go back out. Sometimes it would last a day, and sometimes almost a week. I swapped out all four sensors, but it still does it. If i clear the codes with AlfaOBD, it only stays out for a few days.
 
Mine just did this for the first time at about 7,000 miles. Lost 5 tires, with only the front passenger reporting in. Eventually that left the chat as well. I'm giving it a little time to think about what it did and will see how it acts this weekend.
 
So I need to resurrect this thread. My truck is a 2023 2500 Laramie. I use it regularly for towing, as I am on a 2 month trip right now. We have been out for about 2 weeks, and I regularly check the tire pressure readout especially before a drive day. If I am in a place for more than a few days and will be using the truck to travel often I will deflate the rears to 55 psi. When I am going to hook the fiver back up I will air up to 65-70 psi. Yesterday about an hour into a 2 hour drive my TPMS light lit up and glowed yellow. I tried to check the pressures but the readout just displayed "Tire Pressure Temporarily Unavailable". Pulled over checked all four tires, perfect. TPMS light stays on yellow.

No trouble code messages. Hooked up a OBDII scanner that lets me read and clear DTC. It also reported no DTC, Today I started the truck and went to the tire pressure screen, same message displayed. Let it run while I went out and deflated the tire down to about 45 psi. The only change at the dash readout was that the background color behind the message had a red tint. Reinflated the tire, the red tint went away, the message remains.

I am out of warranty by mileage, so any trip to the dealer will be on me. This is frustrating. My fiver has a external TPMS that Bluetooths to a spare cell phone in the cab. It works great. I thought about disconnecting the negative battery cable, but without any DTC in memory, there may not be a point to it.

Mine did it so often that I gave up, no sensors in my tires. Still under warranty here.
 
Has anyone used one of the "code readers" that can detect the sensor signal from the sender in the tire? I thought about buying one, but it may be a waste of money (hundreds) if it is just a glitch in the truck ECM
 
Yes, I picked up an Autel as my TPMS sensors on my chassis cab have become unreliable all of the sudden. I did some basic testing and it scans them and does all it seems to say - but I haven't had time to actually dig into why the sensors are losing contact.
 
This just happened on my 2024 while towing during a 1000 mile trip. I pulled over and checked all four tires and the pressures were fine. When I restarted the truck it stilled showed "TPMS temporarily unavailable". I continued my trip with the TPMS still illuminated and once we got home, unhitched, restarted the truck and the warning was gone. That was two weeks ago and it hasn't come back, fingers crossed.
 
Mine went out yesterday finally. We started up and drove to a store about 15 minutes away and it was on solid we first left. Just before shutting down at the store I noted that the light went off. I checked the readout and the tire pressures were once again displayed. Obviously a glitch deep within the software, one that Ram does not want to address. It would just cost them money.
 
It's ridiculous. Like, "When is a safety feature not a safety feature?" Answer, when you can't trust the display/icon warning message.
 
When I bought my truck the dealer pictures showed that TPS was unavailable. I told them it had to be working for the sale. I don’t know what they did, but it hasn’t happened again since 2022 when I bought it.
