How do I reset the tire pressure monitoring system in a 2023 Toyota Highlander?

Resetting the Tire Pressure Monitoring System (TPMS) in a 2023 Toyota Highlander

The Tire Pressure Monitoring System (TPMS) in your 2023 Toyota Highlander is designed to alert you when tire pressure is low. If you've inflated your tires to the correct pressure or changed a tire, you may need to reset the system. Below are the detailed steps to accomplish this.

Tools Required

• Tire pressure gauge (optional but recommended for verification)
• Owner’s manual (for reference)

Resetting the TPMS

1. Start the Vehicle:

   • Sit in the driver’s seat and ensure that the vehicle is in the "On" position without starting the engine. If your Highlander has a push-to-start, press the start button twice without pressing the brake pedal.

2. Locate the TPMS Reset Button:

   • The TPMS reset button is typically located beneath the steering wheel, near the brake pedal. Check your owner's manual for the exact location if necessary.

3. Press and Hold the TPMS Reset Button:

   • Press and hold the TPMS reset button until the TPMS warning light blinks three times and then turns off. This indicates that the system is resetting.

4. Drive the Vehicle:

   • After releasing the button, drive the vehicle at speeds over 25 mph for about 10-15 minutes. This allows the TPMS to recalibrate and recognize the new tire pressures.

5. Check TPMS Light:

   • After driving, check if the TPMS warning light has turned off. If it remains illuminated, there may be a fault in the system that requires further diagnosis.

Additional Notes

• Temperature Effects: Tire pressure can change with temperature fluctuations. If the TPMS light comes on after temperature drops, verify tire pressure again.
• Faulty Sensors: If the light persists even after resetting and proper inflation, you may have a faulty TPMS sensor that requires professional inspection and possible replacement.

Conclusion

Resetting the TPMS in a 2023 Toyota Highlander is a straightforward process involving checking tire pressures and using the reset button. If issues persist, consult a professional technician for further diagnosis. Regular maintenance of tire pressure is essential for safety and fuel efficiency.
