Solution

1. Tire Pressure Adjustment

Sub-steps:
- Using a tire pressure gauge, measure the pressure of each tire.
- Inflate or deflate each tire to reach the manufacturer-recommended pressure (found on the driver's door jamb).
- Recheck the pressure after adjustment to ensure accuracy.

2. Inspect and Replace TPMS Sensors

Sub-steps:
- Remove the tire from the wheel using a tire machine or hand tools (if replacing).
- Inspect the TPMS sensor for damage or corrosion.
- If damaged, remove the old sensor by unscrewing it from the valve stem.
- Install the new TPMS sensor by securing it to the valve stem and ensuring it is properly seated.
- Reinstall the tire onto the wheel and balance it.

3. Reset the TPMS System

Sub-steps:
- Turn the ignition to the "ON" position without starting the engine.
- Locate the TPMS reset button (usually under the steering wheel).
- Press and hold the reset button until the TPMS light blinks three times, then release it.
- Drive the vehicle for a short distance (about 10-15 minutes) to allow the system to recalibrate.
