What is activation? How to activate a TPMS sensor?

Activating a sensor forces it to transmit tire pressure and temperature and sensor ID and battery status to the vehicle. Autel’s TPMS tools can activate sensors and display tire and sensor information.

OEM sensors can be activated by

1. An Autel TPMS tool; or often with

2. Rapid inflation/deflation of the tire (5 PSI or 20 kPa in 10 seconds)

3. OEM sensors on 2003 and older vehicles, may be activated when a magnet is placed over the sensor valve stem.

All Autel MX-Sensors support these methods of activation.
