TPMS Explained
What Is a TPMS Sensor?
A TPMS sensor, or Tyre Pressure Monitoring System sensor, is fitted inside the wheel to monitor tyre pressure in real time. When tyre pressure drops below the recommended level, the system alerts the driver through the dashboard warning light or vehicle information display.
TPMS sensors help improve road safety, reduce uneven tyre wear, and support better fuel efficiency. They are now common across a wide range of modern vehicles and often need to be replaced when the internal battery reaches the end of its service life.
When replacing sensors, it is important to choose the correct type for the vehicle and understand whether the system requires automatic relearn, OBD programming, or cloning.
