Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical issues.

2. Inspect and Replace Tire Sensors

Sub-steps:
1. Remove the tire from the vehicle using a jack and jack stands.
2. Use a tire iron to loosen and remove the lug nuts.
3. If the tire pressure sensor is damaged, remove the valve stem cap and use a TPMS tool to dismount the sensor.
4. Replace the defective sensor with a new one, ensuring it is compatible with the Camry XV40 model.
5. Reinstall the tire and torque the lug nuts to the manufacturer’s specifications (typically 76 ft-lbs for Toyota).

3. Relearn TPMS Sensors

Sub-steps:
1. Inflate all tires to the recommended pressure.
2. Use the TPMS reset tool or follow the manual procedure to put the system into relearn mode (typically involves turning the ignition key to "ON" position while pressing the TPMS reset button).
3. Drive the vehicle at a speed of 25-30 mph for approximately 10 minutes to allow the sensors to recalibrate.

4. Final Checks

Sub-steps:
1. Reconnect the negative battery terminal.
2. Verify that the TPMS warning light has turned off after successful sensor relearning.
3. Check tire pressure readings on the dashboard to ensure they are accurate.
