What is the TPMS system on an Acura?

About the Acura TPMS System
The TPMS, or Tire Pressure Monitoring System, is an essential safety feature in Acura vehicles. It is designed to monitor the air pressure in the tires and alert the driver if there is a significant loss of pressure. This is crucial for maintaining optimal tire performance and ensuring safe driving conditions.
Types of TPMS in Acura Vehicles:
Acura vehicles utilize two types of TPMS: indirect and direct. The indirect TPMS employs speed sensors from the anti-lock braking (ABS) system to measure the rotational speed of each tire. If a tire rotates faster than the others, it determines that this tire has lost pressure and illuminates the TPMS light. On the other hand, the direct TPMS uses a battery-operated sensor in each tire to read pressure and transmit the information to the vehicle. These systems trigger the TPMS warning light in the dash when a tire loses more than 25% of the recommended tire pressure.
Functionality and Resetting:
The TPMS system in Acura vehicles is designed to alert the driver when there is a possible low tire pressure condition. The pressure display can be accessed using the MID controls on the steering wheel. If the TPMS warning light comes on, it indicates a potential low tire pressure condition, which can occur due to cold weather. In such cases, it is recommended to manually check the tire pressure and inflate the tire to the proper pressure indicated on the door placard. Additionally, the system can be reset by driving the car for a specific duration or following specific steps to reset the sensor for the tire light .
Troubleshooting and Maintenance:
If the TPMS light remains on despite the recommended troubleshooting steps, it is advisable to visit an Acura service and parts center for professional diagnosis and repair. Additionally, it’s important to note that the TPMS is a critical component for the safety of the vehicle, and regular manual checks of tire pressure are still recommended to ensure optimal performance and safety .
In summary, the TPMS in Acura vehicles plays a crucial role in monitoring tire pressure and ensuring safe driving conditions. It employs both indirect and direct monitoring methods and provides alerts to the driver in case of low tire pressure. Regular manual checks and professional maintenance are essential for the proper functioning of the TPMS system in Acura vehicles.
If you have further questions or need assistance with your Acura TPMS, feel free to reach out to the service department for expert guidance and support.

What triggers a TPMS sensor?

When a tire’s pressure drops below the recommended threshold, the TPMS sensors transmit a signal to the vehicle’s computer, which then triggers a low tire pressure warning. This alert allows drivers to address the issue promptly and maintain proper tire inflation (32 psi to 35 psi when they’re cold).

Is it OK to drive with TPMS light on?

As we mentioned earlier, a tire pressure light is a warning, not a command, so you don’t need to pull over immediately if you see it come on. However, driving on underinflated tires can be dangerous and can cause a variety of problems, including poor handling, reduced fuel efficiency, and increased tire wear.

Where is the Acura TPMS reset button?

Overall, the reasons can be vast, which is why it is best to take your car to a technician for professional diagnosis.

Can I reset my TPMS myself?

Hold the TPMS reset button until the tire pressure light blinks three times, then release it. Start the car and wait about 20 minutes for the sensor to refresh. You will find the tire pressure monitor reset button under the steering wheel. Refer to your vehicle’s owner’s manual if you can’t find it.

How do I fix my TPMS on my Acura?

Turn the key to “On” (one position to the right), but don’t start the car. Now hold down the “TPMS Reset” button until the flashing tire pressure light blinks three times. Start the engine and wait 20 minutes. Check your owner’s manual if you have trouble finding the reset button.

What is the TPMS sensor on my Acura?

These sensors are attached to the inside of the valve stems on each tire, allowing individual tire pressures to appear on the information display to quickly identify which tire is affected should the pressure drop below the recommendation.

What does it mean when it says check TPM system?

WHAT IT MEANS & WHAT YOU NEED TO DO. The purpose of the TPMS (Tire Pressure Monitoring System) is to alert you when tire pressure is too low and could create unsafe driving conditions. If the light is illuminated, it means your tires could be underinflated, which can lead to undue tire wear and possible tire failure.

Can I fix my own TPMS?

For handy individuals with some mechanical experience, replacing TPMS sensors can be a DIY project. This option can be cost-effective but requires a certain skill level and the right tools.

Where is TPMS reset button?

Set the parking brake. Look for a button to the left of the steering column labeled with the TPMS icon if it’s there push and hold it until the TPMS indicator in the instrument panel blinks twice.
