Same thing for me. It was in the single digits here and it turned on. All tires were 32-35psi. Bumped them all to 35 and it still stayed on for a few days. Then one morning it was gone. Kinda like magic, but not!boogyman wrote:It does seem to be sensitive. The wifes came on during a cold spell and it was only down to 32. That is if my memory serves me right. I let it stay on for a week or two. Then I finally got around to checking and upping the pressure. It went away on the way to work the next day. So it does it's job if a little too well at times.
