Autel TPMS Sensor | Tire Pressure Sensors in Vehicle Diagnostics and Test
The TPMS indicator will illuminate on your vehicle's dashboard when the tire air pressure falls below the recommended level by 25% or more. Indirect TPMS (iTPMS) systems do not use physical pressure sensors; they measure air pressures using software-based systems; Direct TPMS (dTPMS) directly measures tire pressure using hardware sensors. Don not rely solely on TPMS to monitor your tire pressure. Always use a reliable gauge to manually check it each month.
