Theory Of Operation

The Tire Pressure Monitoring (TPM) Sensor actively monitors the air pressure, air temperature inside the tire, and the internal battery status. Each sensor has a unique ID code. The TPM Sensor transmits the data at regular intervals via an encoded signal to a receiver circuit located in the Radio Frequency Hub Module (RF-Hub).

For vehicles equipped with a Remote Start system, the TPM signal is received by the Remote Start Antenna (RSA), then the RSA sends the signal to the RF-Hub.
