Yesterday, I was heading to work up the freeway (bout a half hour drive) and while cruising my TPMS light went off. I hadn't ran over anything, and when I checked the pressure was fine in all my tires. The light stayed on the rest of the day. This morning before work I checked and it was magically off! Drove picked up my buddy then headed to work. About half way there it came on again, but everything seems A ok pressure wise. Has this happened to anyone? Is it somehow heating up and causing a bad reading? This hasnt happened at all until 2 days ago. Any help would be great.

The TPMS could potentially be faulty and not sending the proper signal. It generally is reset after the car is off for so long, and will come up after a certain duration when the car is on if it never gets a signal from the sensor

What were your pressures exactly?

it usually comes on once you hit about 25psi and will reset after 20 minutes or 20 miles (whichever).

My pressure was within 29-32 when I checked. I just find it weird that it's coming on as it gets warmer ( pressure rises ) It would make more sense if it was on then turned off
