Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the tires are cool.
Safety warning: Wear gloves and safety glasses when handling tools.

2. Check and Adjust Tire Pressure

Sub-steps:
1. Remove valve caps from each tire.
2. Use the tire pressure gauge to measure the pressure in each tire.
3. Compare the readings with the recommended tire pressure (found on the driver’s door jamb).
4. Inflate or deflate tires as necessary using an air compressor or tire inflator.
5. Replace the valve caps securely.

3. Reset TPMS

Sub-steps:
1. Turn the ignition to the "on" position without starting the engine.
2. Locate the TPMS reset button (typically under the steering column or in the glove box).
3. Press and hold the reset button until the TPMS light blinks three times, then release.
4. Start the vehicle and allow it to run for a few minutes for the system to recalibrate.

4. Inspect Tire Pressure Monitoring Sensors

Sub-steps:
1. If the light remains on, remove the tires to access the TPMS sensors.
2. Inspect each sensor for damage or corrosion.
3. Replace any damaged sensors with new ones, ensuring they are compatible with the vehicle's system.
