Solution

1. Tire Pressure Adjustment

Sub-steps:
1. Remove valve caps from all tires.
2. Inflate each tire to the recommended pressure (found on the driver’s side door jamb).
3. Use the tire pressure gauge to confirm that the pressure is correct.
4. Reinstall valve caps securely.

2. TPMS Sensor Inspection

Sub-steps:
1. Jack up the vehicle and remove the tires if necessary to access the TPMS sensors.
2. Visually inspect each sensor for damage or corrosion, especially on the valve stem.
3. If damaged, replace the affected TPMS sensor with a new one.
4. Reinstall the tires and lower the vehicle.

3. TPMS Reset

Sub-steps:
1. With the vehicle in the on position (do not start the engine), locate the TPMS reset button (usually beneath the steering wheel).
2. Press and hold the TPMS reset button until the TPMS light blinks three times, then release the button.
3. Drive the vehicle for a few miles to allow the system to recalibrate.
