When the light comes on in cold weather it means the tire pressure was low before the cold temp, the cold did not drop it by 25% as some people think, just enough to reach the 25% less condition.
I'm sure that the 25% is an approximate number, but 25% of 32 psi is 24 psi.
Make sure your tire pressure gauge is accurate as many are not too great at all.
If that is the case, then yeah... My sensors are bad lol.
