TPMS, which stands for Tire Pressure Monitoring System, is a module in vehicles that monitors the tire pressure. The purpose of the tire pressure monitoring system is to warn you that at least one or more tires are significantly under-inflated, possibly creating unsafe driving conditions. The TPMS low tire pressure indicator is a yellow symbol that illuminates on the dashboard instrument panel in the shape of a tire cross-section with an exclamation point.


Sometimes, the TPMS system may need to be relearned.  A relearn refers to the process of electronically pairing new TPMS sensor(s) to the vehicle’s Tire Pressure Monitoring System. A TPMS relearn is always required when a new TPMS sensor(s) are installed. Without relearning, the sensor will not communicate with the Tire Pressure Monitoring System.
