Solution

1. Tire Pressure Adjustment

Sub-steps:
1. Remove the valve cap from each tire's valve stem.
2. Use the tire pressure gauge to measure the current tire pressure.
3. Inflate or deflate each tire to the manufacturer's recommended pressure (usually found on a sticker inside the driver's door).
4. Replace the valve caps securely after adjustment.

2. TPMS Sensor Reset

Sub-steps:
1. Ensure all tires are at the correct pressure.
2. Access the Tesla touchscreen and navigate to the Service menu.
3. Select "Reset TPMS" to recalibrate the system.
4. Drive the vehicle for a short distance to allow the system to update.

3. Inspect and Replace TPMS Sensors (if necessary)

Sub-steps:
1. Remove the tire from the wheel using a tire machine.
2. Detach the old TPMS sensor from the valve stem.
3. Install the new TPMS sensor onto the valve stem, ensuring it is properly secured.
4. Re-mount the tire onto the wheel, ensuring proper bead seating.
5. Reinstall the wheel onto the vehicle and torque the lug nuts to the manufacturer’s specifications.
