Tire Pressure Monitoring (TPM) Module - Operation






OPERATION

The TPM receives information from each of the sensors in the form of RF signals. The information contained in each of the transmissions provides all the information necessary for the TPM to determine the pressure in each tire as well as the position of the sensor. This autolocating process only happens in the first 10 minutes of any drive cycle while traveling at speeds above 15mph (24 km/h) (The autolocating process will start again only if the vehicle has been shut off for approximately 20 minutes or longer).
