"SERVICE TIRE MONITOR SYSTEM" Dash Warning Light-What to do about it

This warning is telling you that at least one of your Tire Pressure Monitoring System (TPMS) sensors are faulty. These sensors are located inside the tires and cannot be replaced without removing the tire from the rim. If one of them are bad, then the others are sure to follow. The batteries go bad on them and need to be replaced. Best time to do it is when you get new tires.


One thing you can do if you don't want to pay extra mark up fees is to find out what kind of TPMS sensors your vehicle takes and then order them. You should then communicate with the tire dealer/installer that you wish to install those specific sensors in your vehicle at the time of tire change out.




It's also best that you don't try to save money in just changing one of them out. You may as well get them all changed since it's likely the others will go bad before too long as they are probably all around the same age. During the last decade or so it has become law that all vehicles be equipped with TPMS sensors. These sensors are battery run so they go bad often times around the 7 to 10 year mark.
