Solution

1. Preparation

Gather necessary tools:
- Tire pressure gauge
- OBD-II scanner (if needed)
- Torque wrench
- Tire inflator (if pressure adjustments are required)
Ensure the vehicle is parked on a level surface and the tires are cool.

2. Confirm Tire Pressures

Use the tire pressure gauge to check the pressure of all four tires.
Inflate or deflate the tires to the manufacturer's recommended pressure, which can be found on the driver's door jamb.

3. Inspect and Replace TPMS Sensors (if necessary)

If the tire pressures are correct and the TPMS error persists:
1. Remove the wheel from the vehicle using a socket set.
2. Detach the TPMS sensor from the valve stem.
3. Inspect the sensor for damage or corrosion. Replace if necessary.
4. Install a new TPMS sensor and ensure it is securely attached to the valve stem.
5. Reinstall the wheel to the vehicle and torque the lug nuts to the manufacturer’s specifications.

4. Reset the TPMS

Access the Tesla touchscreen:
1. Navigate to 'Service' > 'Tire Pressure Monitor'.
2. Select 'Reset TPMS' and confirm the action.
Monitor the display for any error messages and ensure the TPMS light goes off.
