Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and the tires are cold.
Disconnect the vehicle's battery for safety.

2. Check Tire Pressure

Use a manual tire pressure gauge to check the pressure of each tire.
Inflate or deflate the tires to the recommended pressure as indicated on the driver's door jamb label.

3. Inspect and Replace TPMS Sensors (if necessary)

Remove the tire from the wheel using a tire changing machine.
Inspect the TPMS sensor for any physical damage or corrosion.
If damaged, replace the TPMS sensor with a new one (ensure it is compatible with Tesla Model Y).
Reinstall the tire on the wheel and balance it properly.

4. Reprogram TPMS Sensors

After replacing the sensor, use a TPMS tool to reprogram the new sensor to the vehicle’s system.
Follow the specific reprogramming procedure as outlined in the Tesla service manual.

5. Reset TPMS via Vehicle Settings

Reconnect the vehicle’s battery.
Start the vehicle and navigate to the settings menu.
Select the TPMS reset option and confirm the reset.
