Okay, I know it wasnt really a mystery, but I took my 2008 Accord to the dealer today and found out that apparently it is a common and known issue for the TPMS light to come on during cold weather on the Accords. Theres nothing wrong with it, its just more sensitive than maybe some other cars TPMS systems according to the Service Manager at Honda. He said that if the system was really malfunctioning there would be another light for that, but the one I saw was just for the pressure drop. I had a few pounds of air put in the tires, had the car washed and vacuumed and off I went. He also checked everything including nails in the tires etc and everything was okay. I'm surprised no one else in here had that happen yet. But maybe you all live in warmer climates I don't know.
