This stands for tire pressure monitor sensor. This is a great system to let you know if you’re getting a low tire. Each wheel has a sensor in side, it sends a signal to a module inside your car if a tire gets low it will let you know by turning on a warning light. These sensors have a battery molded inside if the battery goes bad the sensor has to be replaced. If your car is six or seven years old the battery’s may be getting weak. They can be tested with a scanner at your certified service center.
