What is a TPMS Frequency?

The TPMS frequency is the radio wave signal frequency at which a vehicle's tire pressure sensors communicate with the car’s computer. Most frequencies range from 315 MHz to 433 MHz, depending on the vehicle make and model.

How to Find a Car's TPMS Frequency

To determine your car's TPMS frequency, refer to the owner's manual, check the tire manufacturer's guidelines, or use a TPMS tool that can read sensor information. This provides accurate frequency data specific to your vehicle.

Tools to Identify TPMS Frequency

• TPMS Scan Tools: Specialized tools designed to communicate with TPMS sensors directly.
• OBD-II Scanners: Some advanced models can display TPMS frequency data when connected to the vehicle.
• Vehicle Owner's Manual: Often lists the specifications, including the TPMS frequency.

Case Example: Ford Vehicles

For instance, a 2017 Ford Explorer uses a 315 MHz frequency for its TPMS. By consulting the owner's manual or employing a TPMS tool, a driver can quickly confirm this, ensuring sensor compatibility during tire replacements.

Why Is TPMS Frequency Important?

Understanding your TPMS frequency is crucial for proper tire maintenance. Mismatched frequencies can lead to non-functioning sensors, resulting in inaccurate tire pressure readings and potential safety risks.
