Tpms

[HUMMERADDICT]

Been really fricken cold in my parts this week. Yesterday it was 7 below zero. Today it was 16 below zero. My TPMS has been acting up. Yesterday it was "service TPMS" and today it was "low tire." It shuts off after driving for a minute or two and then will turn on again later. Could the cold weather just be messing with it? p.s. Tires have correct presssure.

If your message is low tire, and the message clears after a few minutes of driving, it a low pressure problem in one or all the tires. Air pressure drops 1 lb for each 10 degree drop in air temp. So if on the border of the low end of the setting, and the temps drop a 20 degrees overnight, the light might come on. As you drive, internal friction warms up the air inside the tire, which increases pressure and shut the light off.

If the message is service TPMS than you could have a problem with one or more of the sensors, or the even a possible fault with the BCM which is the TPMS controller.
