What frequency do TPMS sensors transmit at?
As a car owner, it's essential to understand the various components that contribute to your vehicle's safety and performance. One such component is the Tire Pressure Monitoring System (TPMS), which plays a crucial role in ensuring your tires are properly inflated. In this article, we will explore the frequency at which TPMS sensors transmit data and why this is important for your vehicle's maintenance.
What is TPMS?
The Tire Pressure Monitoring System (TPMS) is designed to monitor the air pressure inside your tires. It alerts you when tire pressure falls below a certain threshold, helping to prevent tire blowouts and improve fuel efficiency. There are two types of TPMS: direct and indirect. Direct TPMS uses sensors mounted on each tire to measure pressure, while indirect TPMS estimates tire pressure based on wheel speed.
Transmission Frequency of TPMS Sensors
TPMS sensors typically transmit data at a frequency of every 30 seconds to 1 minute while the vehicle is in motion. This regular transmission ensures that the driver is promptly informed of any significant changes in tire pressure. When the vehicle is stationary, the sensors may transmit less frequently, often every few minutes, to conserve battery life.
Importance of TPMS Transmission Frequency
The frequency of data transmission from TPMS sensors is vital for several reasons:
- Safety: Regular updates on tire pressure help prevent accidents caused by under-inflated tires.
- Fuel Efficiency: Properly inflated tires improve fuel economy, saving you money at the pump.
- Maintenance Alerts: Frequent monitoring allows for early detection of tire issues, enabling timely repairs.
Conclusion
Understanding the transmission frequency of TPMS sensors is crucial for maintaining your vehicle's safety and performance. By staying informed about your tire pressure, you can ensure a smoother and safer driving experience.

Frequently Asked Questions
What is the signal for the TPMS sensor?
Most TPMS sensors will transmit when movement is detected through a simple accelerometer inside. A sensor will immediately send a signal if it detects a sudden loss in pressure, but the TPMS system won't turn the light on if a single transmission is not received.
What frequencies do TPMS sensors use?
TPMS sensors are available in two frequencies: 315MHz and 433MHz. TPMS signals transmit at 433MHz in Europe and at 315MHz in most parts of the world. When replacing a TPMS sensor, be sure to verify it has the correct electromagnetic wave frequency for the vehicle system.
Are all 315MHz TPMS the same?
So to answer your original question, no, not all 315mhz sensors are the same. You need sensors compatible with the RDLR module you have.
What is the difference between 315MHz and 433MHz?
The wavelength of 315 MHz is longer than that of 433 MHz, and the antenna is longer than that of 433 MHz. The directivity is not as strong as that of 433 MHz. When it has good winding properties, the penetration ability of 315 MHz is weaker than that of 433 MHz.
What is the transmission of the TPMS sensor?
Most direct TPMS systems use ultra high frequency (UHF) radio in one of the 'unlicensed' ISM bands (industrial, scientific and medical) for transmitting the data, often around 433 MHz in Europe and 315 MHz in much of the rest of the world.
How often do TPMS sensors send a signal?
The tire pressure sensors send a tire pressure sensor value every 64 seconds when the vehicle is in motion and approximately every 13 hours when the vehicle is not in motion. The sensors also transmit a unique ID code to differentiate the sensors from those on nearby vehicles.
How do I know what frequency my TPMS sensor is?
And key fob frequencies are the same. Because they use the same receiver. We hope these tips can help you save time and get your customers back on the road for more service tips from Continental.
What is the most common TPMS frequency?
315MHz and 433MHz
TPMS sensors are available in two frequencies: 315MHz and 433MHz. TPMS signals transmit at 433MHz in Europe and at 315MHz in most parts of the world.
What frequency do TPMS sensors use?
TPMS sensor signals are low power and low frequency, with most sensors transmitting at 315MHz or 433MHz. Andrew Markel is the director of content for Brake & Front End magazine. He has been with Babcox Media for 20 years.
How do TPMS sensors transmit?
TPMS sensors broadcast using extremely faint electromagnetic waves that radiate outward in all directions. These signals bounce off the vehicle itself and the surrounding environment before eventually reaching the receiver antenna location, which could be located on the windshield, in the wheel well, or in other spots.
