Since the temps have dropped here in Mich, I have been having my TPS flashing telling me my front tires are low, Don't understand why since the pressure still showing 32psi while cold. Computer says I should inflate to 38psi? Seems awful high seeing the rear tires only show 30 @ cold and they don't seem to mind that. Could it be both sensors are bad or over sensitve to the cold? Any one else having these issues?
