How do you reset the TPMS on a Acura MDX?

To reset the Tire Pressure Monitoring System (TPMS) on an Acura MDX, you'll need to follow a few simple steps. The TPMS is designed to alert you when the tire pressure in one or more of your vehicle's tires is low, and resetting it is necessary after changing a tire or adjusting the tire pressure.

Steps to Reset the TPMS on an Acura MDX

1. Park your Acura MDX on a level surface and turn off the engine.


2. Locate the TPMS reset button, which is usually found near the steering wheel or in the driver's side footwell.


3. Press and hold the TPMS reset button for 3-5 seconds until the TPMS indicator light on the dashboard starts flashing.


4. Start the engine and let the vehicle sit for 20-30 minutes, allowing the TPMS to calibrate and the indicator light to stop flashing.


5. Check the tire pressure in all four tires and adjust as needed to the recommended PSI, which can be found in your owner's manual or on the driver's side door jamb sticker.

Once the TPMS has been reset, the indicator light should remain off, indicating that the system is functioning properly and the tire pressures are within the acceptable range.

Troubleshooting TPMS Resets

If the TPMS indicator light continues to flash or the system is not resetting properly, there may be an issue with the TPMS sensors or the system itself. In this case, you may need to consult your Acura dealer or a qualified automotive technician for further diagnosis and repair.

Regularly checking and maintaining the proper tire pressure in your Acura MDX is important for both safety and fuel efficiency. By understanding how to reset the TPMS, you can ensure that your vehicle's tire pressure monitoring system is functioning correctly and keep your tires in top condition.

How do you reset the TPMS on a 2005 Acura MDX?

(Only for Older Acura Cars With Turn-Key Ignitions): Turn the key to the “On” position, but don't start the car. Then, hold the TPMS light reset button, wait for the tire pressure light to blink three times, and then release it. After you start the car next, wait 20 minutes for the sensor to refresh itself.

Where is the TPMS reset button on Acura MDX?

The TPMS reset button on an Acura MDX is either a physical button under the steering wheel with a TPMS icon, or the reset is performed through the vehicle's display audio system via the settings menu. If there is a physical button, press and hold it until the light blinks twice. If not, navigate to Settings > Vehicle > TPMS Calibration and touch "Calibrate" on the touchscreen.
 
Using the physical button

• Locate the physical button, which has a TPMS icon on it, typically to the left of the steering column under the dashboard. 
• Turn the ignition to the "ON" position without starting the engine. 
• Press and hold the button until the TPMS indicator light in the instrument panel blinks twice. 
• Release the button. The calibration process will begin.

Using the display audio system
Press the "Home" button on the display audio screen, Go to Settings, Select Vehicle, Choose TPMS Calibration, and Press Calibrate.

After resetting

• Drive the vehicle at speeds between 30 and 60 mph for at least 30 minutes for the calibration to complete. 

Can I reset my own TPMS sensor?

Yes, you can reset your TPMS yourself, but the process varies by vehicle. First, check that all tires are inflated to the correct pressure, which is listed on the driver's side door jamb. Then, look for a physical reset button, check your car's infotainment system for a "TPMS calibration" option, or perform a specific procedure like disconnecting the battery or overinflating and deflating the tires. After performing the reset, you may need to drive for a short time for the system to fully recalibrate. 
Before you begin

• Check tire pressure: Park on a level surface and use a pressure gauge to check that all four tires (and the spare, if applicable) are at the manufacturer's recommended PSI, found on the sticker on the driver's side door jamb or in your owner's manual. 
• Wait for tires to cool: Ensure your tires are cool for an accurate reading.

DIY reset methods
Method 1: Use a dedicated reset button 

1. Ensure the ignition is turned to the "ON" position without starting the engine. 
2. Locate the TPMS reset button. It is often a small button with a TPMS icon, typically found under the dashboard to the left of the steering wheel, in the glove box, or on the center console. 
3. Press and hold the button until the TPMS warning light blinks three times, then release it. 
4. Start the car and drive for a few minutes. The light should turn off.

Method 2: Use the infotainment or dashboard menu 

1. Navigate to the "Settings" menu on your infotainment screen. 
2. Find the "Vehicle" settings and look for a "TPMS calibration" or "Tire pressure" option. 
3. Select "Calibrate" to start the process. 
4. Drive for about 20–30 minutes at speeds between 30–60 mph to allow the system to complete the recalibration. 

Method 3: Try a "re-learn" procedure (some vehicles) 

1. Turn the ignition to "ON" and press the "Info" or "Check" button until the display says "Press CHECK button to relearn tire positions". 
2. Press the "CHECK" button to start the relearn procedure. 
3. The system will signal which tire to start with (e.g., the driver's front tire). 
4. Let air out of that tire for about 5 seconds, or until the horn beeps to confirm the system has registered it. 
5. Repeat this for the other three tires in the correct sequence.

If the light remains on

• Check your owner's manual: Your car's manual will have the most accurate instructions for your specific make and model. 
• Consider sensor failure: The TPMS sensors have a lifespan of about 7-10 years. If the light comes on shortly after a reset, one or more of the sensors may have failed and will need to be replaced. 
• Visit a professional: If you cannot get the light to turn off after trying these methods, a professional can use a diagnostic tool to check the system and the sensors. 

Where is my TPMS reset button located?

Process will begin if there's no button the procedure is done with the display audio. Begin by pressing the home. Button then touch settings touch vehicle next and then TPMS calibration.
