Solution

1. Preparation

Tools Required: Tire pressure gauge, OBD-II scanner, TPMS reset tool (if necessary), jack and jack stands, lug wrench.
Safety Warnings: Ensure the vehicle is parked on a level surface and the engine is off before working on the tires.

2. Adjust Tire Pressures

Sub-steps:
1. Remove valve caps from each tire.
2. Inflate or deflate each tire to the manufacturer's recommended pressure (found on the driver’s side door jamb).
3. Replace valve caps securely.

3. Reset the TPMS

Sub-steps:
1. Turn the ignition key to the "ON" position without starting the engine.
2. Locate the TPMS reset button under the dashboard near the steering column or through the vehicle settings on the MID.
3. Press and hold the reset button until the TPMS light blinks three times, then release the button.
4. Start the vehicle and check if the TPMS light turns off after a short drive.

4. Replace TPMS Sensors (if necessary)

Sub-steps:
1. Jack up the vehicle and remove the wheel where the sensor needs replacement.
2. Use a lug wrench to remove the lug nuts and take off the wheel.
3. Remove the tire from the wheel rim using a tire machine.
4. Replace the faulty TPMS sensor by unscrewing it from the valve stem and installing a new one.
5. Reassemble the tire to the wheel and reinstall it on the vehicle, ensuring proper torque on the lug nuts (typically 76-80 ft-lbs).
