Ever since we bought the car the tires continuosly loose air pressure. I have had to replace two tire pressure sensors at approximately $200 a piece do to the valve stem cracking and snapping off. I recently replaced a third sensor with a $25 valve stem and the tire has held pressure for the last month. Thesystem continuosly flashes an annoying text message to service the tire system. How do I stop the text without replacing a valve stem with a part that will leek air.

Unfortunately the TPMS is a mandatory equipment since 2005. I have seen people remove all the sensors, remove the tire from the spare and just insert them into the spare tire, than set the pressure to the correct level. Now all the sensors are located in 1 pressurized chamber and will never set the warning light. Here is the problem though: - By a legal stand point of view you are driving a non-DOT approved vehicle, since DOT requires a working TPMS. - In case of an accident you could be reliable. What I'd do to my car (when it's possible): Modify the sensors by removing the valve part and attached it into the middle of the rim by belts at 180 degree from the valve location. Most tire shop has these belts since early systems were design like this, so it will be perfectly legal and the sensors will be protected even more. You can get a regular valve seated into the rim and hopefully no more problems. Zee
