What frequency is my TPMS sensor?
Most TPMS sensors in direct systems transmit on fixed radio frequencies: 315 MHz in North America and 433 MHz in Europe and many other markets. Some sensors are dual-band or programmable to cover multiple regions, and vehicles with indirect TPMS do not transmit a radio signal at all. To know your exact frequency, check the sensor itself, your vehicle’s documentation, or query a TPMS tool or dealer.
Direct vs. indirect TPMS
Direct TPMS sensors are mounted in each tire and continuously transmit a unique radio signal. Indirect TPMS uses the vehicle's wheel-speed sensors to infer low pressure and does not send a dedicated RF signal.
Why frequency matters
The receiver in the vehicle is tuned to a specific frequency. If you replace a sensor with the wrong frequency, the system may fail to read the sensor data or trigger warnings.
Common TPMS frequencies by region
Here are the frequencies most commonly encountered, noting that dual-band and factory-programmed options exist.
- 315 MHz — standard in the United States, Canada and some Latin American markets
- 433 MHz (often 433.92 MHz or 434.0 MHz) — standard in Europe, parts of Asia, and many other regions
- Dual-band or programmable sensors — some OEM or aftermarket sensors can operate on both 315 and 433 MHz, or be programmed to the correct region
In practice, many vehicles shipped to different regions use one of these frequencies, and modern sensors or adapters may support multiple bands to cover global markets.
How to determine your TPMS frequency
Use a diagnostic tool, inspect labeling, or consult official documentation to confirm the exact frequency for your vehicle. The steps below guide you through the process.
- Check the sensor stamping or the valve stem for frequency markings such as 315 or 433.92 MHz, though not every sensor visibly marks the frequency.
- Consult the vehicle owner’s manual או service manual for TPMS specifications and sensor compatibility information.
- Use a professional TPMS tool or scanner that reads sensor data or supports multi-frequency operation; it can display the sensor transmit frequency or indicate compatible bands.
- If you are replacing a sensor, verify the replacement part is rated for your region (315 MHz, 433 MHz, or dual-band) and, if possible, have it programmed to match your vehicle.
- For indirect TPMS, there is no transmit frequency to verify; the system relies on ABS wheel-speed data instead.
Confirming the frequency ensures your replacement sensors will communicate correctly with the vehicle’s TPMS receiver.
Summary
TPMS radio frequencies vary by region and by sensor type. The two most common frequencies are 315 MHz (North America) and 433 MHz (Europe and many markets), with dual-band sensors also available. Indirect TPMS does not use RF transmission. To confirm your exact frequency, check the sensor, consult manuals, or use a qualified TPMS tool or dealer service.
