Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Disconnect the battery to avoid electrical issues during repair.

2. Inspect and Replace TPMS Sensors

Remove the Wheel:
- Use a jack to lift the vehicle and secure it on jack stands.
- Loosen lug nuts with a socket wrench and remove the wheel.
Remove TPMS Sensor:
- Locate the TPMS sensor on the inner side of the wheel.
- Use a valve tool to unscrew the sensor from the valve stem carefully.
Install New Sensor:
- If the sensor is faulty, replace it with a new one compatible with the Tesla Model 3.
- Secure the new sensor to the valve stem and ensure it is tightly fastened.

3. Reinstall Wheel and Reset TPMS

Reinstall Wheel:
- Place the wheel back onto the hub, hand-tighten the lug nuts, and lower the vehicle.
- Use a torque wrench to tighten lug nuts to the manufacturer's specified torque (typically around 100-120 ft-lbs).
Reset TPMS:
- Reconnect the battery.
- Through the vehicle's touchscreen, navigate to the settings and select the TPMS reset option. Follow on-screen instructions to complete the reset.
