TPMS.
Depending on the type of sensor, the quality of the sensor and its purpose, multiple signals are sent from the TPMS sensor to the receiver in the car.
The following information signals are almost always sent:
- The air pressure in the tire
- The temperature
- Whether the wheel is moving
- The battery status
- The ID number of the sensor
The OE sensors such as Huf send out 74 signals, and here the TPMS sensor is part of the total information provision of the system.
