Module, Tire Pressure Monitoring (TPM): Operation
WARNING: This page is about a different car, the 2020 Chrysler 300 and 2019 Chrysler 300. However, it is still accessible from the selected car via links, so may be relevant.
The Tire Pressure Monitoring (TPM) module receives information from each of the TPM sensors in the form of Radio Frequency (RF) signals. The information contained in each of the transmissions provides all the information necessary for the TPM module to determine the pressure in each tire as well as the position of the TPM sensor. This auto locating process only happens in the first 10 minutes of any drive cycle while traveling at speeds above 15 km/h (24 mph). The auto locating process will start again only if the vehicle has been shut off for approximately 20 minutes or longer.
