Hi so my issue i am having i hope someone can shed some light on why the light comes on. in the early mroning or really late evneing when i go to leave work i work up at 10,000 feet up the canyon and my TPMS light will be on i check the tire presure and all the tires read 31psi wich is more than good enough to keep the light off from what i understand.
then about 20 or 30 miles latter on my drive home the light goes out and its all fine.
anything you can think of thats causing this to happen ?
thanks guys.

What kind of car? Does the spare have a sensor?

bagwell

is this every day all the time or occasionally?

maybe the battery in one of your sensors is going bad?

this happens occasionally-like once every 6 months in my '10 A5 (at sea level tho) for no apparent reason - all psi's fine - I can manually reset the TPMS inside the car but it's a little scary when I get a warning while going 70mph on a freeway...crappy system too...doesn't state which tire (LF/RF, etc).
