Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Turn off the ignition and remove the key.

2. Inspect and Replace TPMS Sensors

Tools Required: Tire iron, TPMS sensor tool, jack, jack stands
Sub-steps:
1. Loosen the lug nuts on the affected tire using a tire iron.
2. Raise the vehicle using a jack and secure it with jack stands.
3. Remove the wheel by fully unscrewing the lug nuts.
4. Use a TPMS sensor tool to check the status of the sensors. If faulty, proceed to replace them.
5. To replace, remove the old sensor by unscrewing the valve stem nut and replacing it with a new TPMS sensor. Secure it firmly.
6. Reinstall the wheel and tighten the lug nuts to the manufacturer's specified torque (usually around 90-100 lb-ft).

3. Reset the TPMS

Tools Required: OBD-II scanner (if needed for reset)
Sub-steps:
1. Turn on the ignition without starting the engine.
2. Follow the specific reset procedure outlined in the owner's manual, which may involve pressing the TPMS reset button or using an OBD-II scanner.
3. Drive the vehicle for a short distance (usually around 10 minutes) to allow the system to recalibrate.
