In discussions with the SA, though, I think the next step is to replace the sensors in each tire. He was pretty sure that the failure of a single sensor would cause the TPMS malfunction where none of the pressures are displayed. I think the sensors are battery powered, and they're normally switched out when you get new tires. You may have a sensor with a low battery.

I'm still on my original tires.
Thanks for the reply. Mine are flaking on and off. They work for a day or two then the system fails. I made an appointment at the dealer for Thursday and they will run it down. I am going to guess one of the units has failed or is defective.
