Tpms Light Blinking
 

The tire pressure monitoring indicator blinks when I have traveled for 50-60 miles at highway speeds. It blinks, may go steady, and goes our after a few minutes. I run 35 psi cold and that usually goes to about 37psi hot. I have checked the tires cold and when the light has been blinking and find no problems. Any ideas?

Did you ever hit or scrape a curb with a rim ??
If so you might have hit the valve stem and the TPMS for that tire is messed up.

There is a gauge that tells you if the sensor is bad..
Most good tire shops have them...
