Tire Pressure Warning Light in 2020 Toyota Camry

Repair Instructions
If Tire Pressure is Low:
  1. Inflate Tires:
    • Use an air compressor to inflate each tire to the recommended pressure.
    • Recheck with the tire pressure gauge.
If a Tire is Damaged:
  1. Repair or Replace Tire:
    • For punctures: If the puncture is within the tread and less than 1/4 inch, a professional repair may be possible.
    • For sidewall damage or severe tread wear: Replace the tire.
If TPMS Sensors are Faulty:

  1. Replace TPMS Sensor:

    • Tools Required: Tire changing tools, TPMS sensor programming tool (if required).
    • Procedure:
      • Remove the wheel from the vehicle.
      • Use a tire changing machine to dismount the tire from the rim.
      • Remove the old TPMS sensor and install the new sensor.
      • Reinstall the tire onto the rim and balance it.
      • Reinstall the wheel onto the vehicle and torque the lug nuts to the manufacturer’s specifications.

  2. Reprogram TPMS Sensor:

    • Depending on the sensor used, you may need a programming tool to sync the new sensor with the vehicle's TPMS system.
Final Steps
  • After completing the repairs, clear any trouble codes using the OBD-II scanner.
  • Drive the vehicle for a short distance to ensure the tire pressure warning light resets.
  • Regularly check tire pressures and monitor for any unusual handling or wear.
Conclusion

If the tire pressure warning light remains on despite checking tire pressures and sensors, or if you are unable to diagnose the issue, consult a professional technician for further diagnosis and repair.
