Interesting... when I read the manual, it mentioned that it would only flash the TPM light if tire pressure dropped 25% below the recommended value. I assumed this threshold would be the same for the upper range (above the recommended value) as well, but maybe not.

 

Have you folks checked the batteries on your sensors?

Also, if you can get a free OBD-II/CAN BUS scanner, you should be able to figure out which sensor is giving you problems. Unfortunately, our cars simply have a single display for all four tires (unlike the Dodge info system, which shows all four simultaneously on a display.)

 

Just from my own personal experience, my Tire pressure kept coming on and it ending up being a slight crack in the rim. I constantly had to put in the tire and the dealership couldn't figure it out. It took two dealerships and tire shop to finally nail down the problem.
