Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface with the engine off.
Wear safety gloves and glasses.

2. Check and Adjust Tire Pressure

Sub-steps:
1. Remove the valve caps from each tire.
2. Use a tire pressure gauge to measure the current pressure in each tire.
3. Inflate or deflate the tires to match the recommended pressure specified on the driver’s side door jamb sticker.
4. Replace the valve caps securely.

3. Reset TPMS System

Sub-steps:
1. Turn on the ignition without starting the engine.
2. Access the vehicle settings on the dashboard display.
3. Navigate to the TPMS reset option.
4. Follow the prompts to reset the system.
5. Turn off the ignition and restart the vehicle to confirm that the warning light is off.

4. Replace TPMS Sensors (if faulty)

Sub-steps:
1. Remove the wheel from the vehicle using a socket set.
2. Detach the tire from the rim using a tire removal tool.
3. Unscrew the old TPMS sensor from the valve stem and replace it with a new one.
4. Reassemble the tire onto the rim and reinstall the wheel onto the vehicle.
5. Tighten lug nuts to the manufacturer's specified torque (typically 80-100 ft-lbs).

5. Verify Sensor Functionality

Sub-steps:
1. Use a TPMS tool to check if the new sensors are transmitting properly.
2. Ensure that the TPMS warning light is off after the reset.
