3. Replace valve caps after adjustment.

3. Inspect and Replace Damaged Tires

Sub-steps:
1. Remove the wheel if necessary for better access.
2. Inspect the tire for holes or issues.

4. Reset the TPMS

Sub-steps:
1. Turn the ignition to the ON position without starting the engine.
2. Locate the TPMS reset button (usually beneath the steering wheel).
3. Press and hold the reset button until the TPMS light blinks three times, then release.
4. Start the vehicle and check if the light goes off.

5. Replace TPMS Sensors (if necessary)

Sub-steps:
1. Remove the tire from the wheel (if sensor replacement is needed).
