Flashing TPMS light

[Dennis Martinson]

I have a towing package in my 2009 Ram 1500 (70k actual miles). I run the tire pressure at 65 psi when towing my travel trailer, 55 psi when I'm not. Recently my TPMS light came on, flashed perhaps a half-dozen times and then stayed on. I checked the tire pressure, all at 55 psi. I'm thinking a wheel sensor has puked, any easy way to check this? My EVIC system shows no faults or messages.

Welcome to the forum.

So does your EVIC have a display page that shows PSI at each corner?

I didnt know the 2009 could show individual tire pressures. Regardless if its flashing its a fault, one or more of your sensors have decided to die.

No, it can't report tire pressure. I scrolled through the EVIC to see if it'd generated a fault message pertaining to the TPMS. Looks like a trip to my friendly repair shop for some diagnostic time.

Should be quick to find which wheel isnt responding. From there its a new sensor.

I might be mistaken, but I think some automotive stores that have scanners can hook up and see which tire it is (same ones that give you your trouble codes for free usually). Then, as William said, its a matter of replacing it. If you don't feel like doing it yourself, and have a little bit of money, you can pay a reputable shop to do it for you. Any place that sells tires should be able to replace one of those for you.
