On my sister's 08, it came on when a tire was down to 27lbs and that
way 2 weeks after she bought the car. If I recall the pressure should
be at 32. So if it is going off it is because it is low about 5 lbs of
air. Check it and add to it accordingly. It hasn't come on her car
since the issue was first encountered 3 months ago.

Hello folks,

I have a relative who also has a 2008 Accord sedan, auto, except hers is a
LX-P with the 16" wheels instead of the 17" on mine. The same thing happened
with her TPMS light going on and off due to cold. It must be a cold issue
for that model. When the outside temp drops to 25F or lower the TPMS will
stay on and remain on even on the highway until the outside temp goes to at
least 30F and after at least a few hours.

Apparently its not a sensor problem or a tire problem its just a Honda fluke
with that model and with a certain degree of coldness...weird!
