Solution

1. Preparation

Gather necessary tools and replacement parts.
Ensure the vehicle is parked on a level surface and the tires are cool.
Disconnect the negative terminal of the battery to prevent electrical issues during repair.

2. Inspect and Replace TPMS Sensors

Remove the Tire:
- Loosen the lug nuts using a socket set.
- Lift the vehicle with a jack and secure it with jack stands.
- Remove the lug nuts and take off the tire.
Access the TPMS Sensor:
- If necessary, demount the tire from the wheel using a tire machine or manual tools.
- Locate the TPMS sensor attached to the valve stem.
Test the Sensor:
- Use a TPMS tool to check the sensor's functionality and battery status.
- If the sensor is non-functional, proceed to replace it.
Replace the Sensor:
- Remove the old sensor from the valve stem.
- Install the new TPMS sensor, ensuring it is securely attached.
- Re-inflate the tire to the recommended pressure.
Reassemble the Tire:
- Mount the tire back onto the wheel if demounted.
- Reinstall the tire onto the vehicle, tightening the lug nuts in a star pattern to the manufacturer's torque specification (typically around 100-110 ft-lbs).

3. Reset the TPMS

Reconnect the Battery:
- Reconnect the negative terminal of the battery.
Calibrate the TPMS:
- Navigate to the TPMS reset option in the Tesla touchscreen interface (Settings > Service > Tire Pressure Monitoring).
- Follow the prompts to recalibrate the TPMS system.
