TPMS Sensor
A device that monitors tire pressure and sends real-time data to the vehicle system.

TPMS (Tire Pressure Monitoring System) sensors are small electronic devices fitted inside tire valves or attached to the rim. They continuously measure air pressure and temperature, sending data wirelessly to the vehicle's ECU. If a tire loses pressure, the dashboard warning light alerts the driver. Proper TPMS function improves safety, reduces tire wear, and enhances fuel economy. Sensors require periodic recalibration or replacement due to battery depletion. Technicians use TPMS tools to program and diagnose sensor communication issues.
