What is the TPMS system on the Acura RDX?
The Tire Pressure Monitoring System (TPMS) is a critical safety feature in modern vehicles, including the Acura RDX. It helps drivers maintain proper tire pressure, ensuring optimal performance, fuel efficiency, and safety. In this article, we’ll explore what the TPMS system is, how it works, and why it’s essential for your Acura RDX.
What is the TPMS System?
The TPMS, or Tire Pressure Monitoring System, is an electronic system designed to monitor the air pressure inside your vehicle’s tires. It alerts the driver when one or more tires are significantly under-inflated, which can lead to unsafe driving conditions. In the Acura RDX, this system is integrated into the vehicle’s onboard computer and provides real-time feedback to the driver.
How Does the TPMS Work?
The TPMS in the Acura RDX uses sensors to measure tire pressure. These sensors are typically located inside the tire, attached to the valve stem, or mounted on the wheel. Here’s how the system operates:
- Pressure Sensors: The sensors continuously monitor the air pressure in each tire.
- Data Transmission: The sensors send pressure data to the vehicle’s computer system.
- Warning Light: If the pressure in any tire drops below the recommended level, the TPMS activates a warning light on the dashboard.
In some cases, the Acura RDX may also display the specific tire with low pressure, making it easier for the driver to address the issue promptly.
Why is the TPMS Important?
Maintaining proper tire pressure is crucial for several reasons, and the TPMS plays a vital role in ensuring this. Here are the key benefits:
- Improved Safety: Under-inflated tires can lead to blowouts or reduced handling, increasing the risk of accidents.
- Better Fuel Efficiency: Properly inflated tires reduce rolling resistance, improving fuel economy.
- Extended Tire Life: Correct tire pressure minimizes uneven wear, prolonging the lifespan of your tires.
- Environmental Benefits: Efficient tire pressure reduces CO2 emissions by improving fuel efficiency.
What to Do When the TPMS Warning Light Comes On
If the TPMS warning light illuminates on your Acura RDX dashboard, follow these steps:
- Check Tire Pressure: Use a tire pressure gauge to measure the pressure in all four tires. Compare the readings to the recommended levels found in your owner’s manual or on the driver’s side door jamb.
- Inflate Tires: Add air to any tires that are below the recommended pressure. Be careful not to overinflate.
- Inspect for Damage: If a tire is consistently losing air, inspect it for punctures or other damage and have it repaired or replaced as needed.
- Reset the TPMS: After addressing the issue, you may need to reset the TPMS system. Refer to your Acura RDX owner’s manual for specific instructions.
Conclusion
The TPMS system in your Acura RDX is a valuable tool for maintaining tire health and ensuring safe driving conditions. By understanding how it works and responding promptly to its warnings, you can protect yourself, your passengers, and your vehicle.

Frequently Asked Questions
Why does my Acura say check TPMS system?
Any time that the TPMS warning light comes ON, there is a possible low tire pressure condition. Tire pressure can drop due to cold conditions, and this drop in pressure may cause the TPMS light to come ON. As the tire warms up under normal driving conditions, the light may turn OFF.
What is the TPMS system malfunction on Acura?
When the malfunction indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions may occur for a variety of reasons, including the installation of replacement or alternate tires or wheels on the vehicle that prevent the TPMS from functioning properly.
Why is my TPMS light on but my tires are fine?
This can be caused by a low battery voltage in the sensor, or the sensor has been damaged by tire tech while installing a tire. If it's the low air light, but all the tires have the correct pressure (32psi) you have a bad sensor.
Can I drive with the TPMS light on?
This is why you should maintain proper inflation pressure and try to avoid driving when the TPMS light is on. If you absolutely must drive a short distance on a tire with severely low pressure, drive very slowly and use extreme caution. The tire should be inflated or changed before driving anywhere.
How can you tell if TPMS is bad?
If you notice that your tires have low air pressure and there was no warning from the system, it is most likely due to a failure of a TPMS sensor. Using a tire pressure gauge indicates a problem with the sensor or a tire. Another noticeable side effect is when steering becomes tight.
