Solution

1. Preparation

Gather necessary tools and parts.
Safety warning: Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Inflate Tires

Sub-steps:
1. Locate the recommended tire pressure (usually found on the driver’s side door jamb).
2. Use an air compressor to inflate tires to the recommended PSI.
3. Recheck the pressure with a gauge to ensure accuracy.

3. Reset TPMS

Sub-steps:
1. Turn on the vehicle without starting the engine.
2. Navigate to the TPMS reset option in the vehicle's settings menu.
3. Follow the prompts to reset the TPMS. This may require driving for a short distance to complete the reset.

4. Replace Faulty TPMS Sensors (if necessary)

Sub-steps:
1. Remove the tire from the wheel using a tire machine.
2. Replace the TPMS sensor by unscrewing it from the valve stem.
3. Install the new sensor, ensuring it is correctly secured.
4. Reinstall the tire and balance it.

5. Verify Repairs

Sub-steps:
1. Test drive the vehicle for 10-15 minutes to check if the TPMS light turns off.
2. Monitor tire pressures again with a gauge to confirm they are stable.

Tools Required:

Tire pressure gauge
Air compressor
TPMS scan tool
Tire machine (for sensor replacement)
Basic hand tools (sockets, wrenches)

Parts Required:

New TPMS sensors (if faulty)
Valve stems (if necessary)
