What Is a TPMS Sensor?
A TPMS sensor (tire pressure monitoring system sensor) measures real-time tire pressure and alerts the driver when air drops.
It maintains vehicle safety, stability, and accurate system performance across all wheels.
When Should You Replace a TPMS Sensor?
A sensor needs replacement when the internal battery expires, the valve stem corrodes, or the system shows persistent TPMS errors.
Replacing worn sensors ensures reliable pressure data and prevents failures during tire rotation or road use.
Direct vs. Indirect TPMS
Direct TPMS uses a valve-stem sensor for precise air-pressure readings, while indirect TPMS detects pressure changes through wheel speed.
Confirm system compatibility with your vehicle’s brand and model before purchasing a replacement sensor.
