how to reset the tire pressure light on Acura MDX YF3 (2022-Present)

Symptoms

• TPMS warning light illuminated on the dashboard.
• Tire pressure may be low in one or more tires.
• Potentially uneven tire wear due to incorrect pressure.

Diagnostic Steps

1. Check Tire Pressure:

   • Use a tire pressure gauge to measure the pressure in all four tires.
   • Compare the readings against the recommended pressure found on the driver’s door jamb sticker.

2. Inflate Tires:

   • If any tire is below the recommended pressure, inflate it to the correct level.
   • Make sure to check the spare tire if applicable.

3. Inspect Tire Sensors:

   • If the tire pressures are correct and the light remains on, inspect the tire pressure sensors for any damage or malfunction.

4. Scan for Error Codes (optional):

   • Use an OBD-II scanner to check for any error codes related to the TPMS system, which may indicate a problem with one of the sensors.

Repair Instructions (Resetting TPMS Light)

1. Ensure Tire Pressures are Correct:

   • Before resetting, make sure all tires are properly inflated to the recommended pressure.

2. Turn Ignition On:

   • Insert the key fob into the ignition and turn it to the "ON" position without starting the engine.

3. Locate the TPMS Reset Button:

   • The TPMS reset button is usually located under the steering wheel or near the lower dashboard area.

4. Press and Hold the TPMS Reset Button:

   • Press and hold the TPMS reset button until the TPMS indicator light blinks three times, then release the button.

5. Start the Engine:

   • Start the engine. The TPMS light should turn off after a few moments. If it remains illuminated, repeat the process.

6. Check for Errors:

   • If the light does not turn off after resetting, there may be a fault in one of the sensors that needs to be diagnosed.

Safety Warnings

• Always ensure tires are at the recommended pressure before driving; driving on under-inflated tires can lead to blowouts and loss of control.
• Use caution when working near the vehicle’s electrical system, and ensure the vehicle is in park with the engine off when resetting the TPMS.
