Tire Pressure Monitoring System
Most newer model vehicles come standard with Tire Pressure Monitoring Systems, commonly known as TPMS. This with a few exceptions depending on make of vehicle consists of sensors that are attached to the valve stem of the wheel. The purpose of this sensor is to inform the driver when the air pressure is below the recommended setting. The indicator light pictured above should go off once the accurate pressure is reached. If the light continues to illuminate or begins to blink it is a good indication that there is a fault within the TPMS, that is normally a sensor that has gone bad. Most common reason for sensors going bad is simply a dead battery.
*Replacement consists of Diagnosis, Installation of new sensor and reprograming of vehicle TPMS system.
