TPMS fail...
This morning the light was on, When I was on lunch break it was still on so I reset it...it came back on, then went off a minute or two later and never came back on...what would cause that?

So did mine, when I was in the airport 2 hours away from home. I'm glad I actually checked the pressure though. It was 20 psi and looked just like the other tires.
Seriously though...if your any warning light comes on, maybe it's doing its job.

TPMS should flag a 5 psi difference. Example.... if the lowest tire is at 28 and the highest is at 32, there is a 5 psi difference and it sets the light.
As a service shop, we provide Nitrogen for tires. The XB comes with nitrogen fill from Scion for better sensor life. (Lots of good reasons for nitrogen, read up on it) We have found that on the first cold days of the season, the system will be low on pressure and flag the TPMS. A quick top off and the tires are good till they have a leak, no matter the temsp outside. We called a top chemical company and they said there is a formula out there to set the pressure per ambient temp so that will not happen when the weather turns cold, but the easy thing is to just set the pressure on the coldest day and it's good from then on.
I agree that checking the tire pressure is a good thing to do, but checking it too often or not checking it correctly will let air/nitrogen out and eventually force you to add to the tire. Just a thought.
