Stryfox,
Get yourself a good analog tire gauge, if you don't have one already. The TPMS will register when there is a 25% (8 lbs.) loss of air pressure, this is also cumulative (ex. all 4 tires down 2 lbs. each). The TPMS will not reset until all tires are brought up to the proper pressure. I have found that if you leave your car running (or the key in the ON position) while inflating the tire(s) and turning the car off after inflation and waiting approx. 2 minutes and restart your car the TPMS will rest easier. I have had many problems with the TPMS...cold weather/sudden drop in temp...aftermarket wheels.
