Here's a little different wrinkle on this thread: Driving along the other day in my '06 Limited coupe, minding my own business and the TPMS light comes on...I continue on home and let the car sit overnight, next morning I check the pressures and all are right on. Using a borrowed Autel TS408, I check the sensors and three are putting out no signal.

Hmmm. I think I'll just ignore the light and keep an extra eye on the pressures. Light says on for several days and today it goes out while driving. Get home and check the sensors with the Autel TS408 and all four are putting out a correct signal. I don't drive the car every day so this story spans a couple of weeks.

Any thoughts?
