Well today I got in my car to go to work. As soon as I left my driveway the tire pressure sensor goes off telling me to check the front right. I drive to service station and add some air, but on visual inspection the tire looks fine and not low at all. I drive a little further and it goes off again telling me to check the front left. Once again the tire is not low and everything looks fine. How sensitive is the tire pressure sensor on this car? I have only had it go off one other time and that was while exiting one of those brushless car washes. I'm starting to think the outside air temperature is playing a large role in the problem. This morning it was a little cool (50 degrees F) compared to most mornings of around 60-65 here in Atlanta.
