Could be battery depending on how old, temp plays with it also. Once in learn mode use a tool like this.

I'm a former Memphian myself, hence my username!

I am having the exact same issue. From my research the battery life on average is 5-7 years. I assume some TPMS sat on the shelf longer prior to install than others, hence the wide time range. The dealer put brand new tires on my truck before I purchased it, but I am sure left the TPMS sensors alone. I am taking the truck by Monday for them to look it over and will let you know what they determine.

Just to add to this thread, I recently purchased a 2010 F150 Lariat with Triton V8 with 35,000 miles. Tires new with 2000 miles on them. I was driving the truck on the Interstate at 80 mph in a severe thunderstorm when the Tire Pressure Sensor fault came on the message center. I pulled off at the rest area and checked the tires. Tires all good. Once I parked, the warning went away. Got back on there road, drove 15 miles and warning came on again. I was almost home so I drove home and checked tires. Still fine. As I was getting my 6 year old out of the backseat, I noticed my car charger plugged into the rear power outlet. I unplugged it and went in the house. It's been 2 weeks now and no warning light. I asked the previous owner and she never had that issue and she had never used the rear power outlet. The first time I had used that rear power outlet was that night before I headed onto the Interstate. I'm putting two and two together and I'm thinking that that power outlet has something to do with it. The warning went away after I unplugged the charger at the rest area. When I plugged it back in, the warning cane back after a few miles. Anyone else have this issue? Sure saved me from taking it to the tire shop to replace the sensors.
