Solution

1. Preparation

Gather all tools and parts needed.
Ensure the vehicle is parked on a level surface and turn off the ignition.
Safety gear: Use gloves and safety glasses.

2. Verify and Adjust Tire Pressure

Use a tire pressure gauge to measure the pressure in all tires.
Inflate or deflate tires to the recommended levels specified in the owner’s manual or on the door jamb sticker.

3. Inspect and Replace TPMS Sensors

Tools Needed: Tire iron, jack, jack stands, TPMS sensor tool, replacement TPMS sensors if necessary.
Jack up the vehicle and secure it with jack stands.
Remove the wheel using the tire iron.
Locate the TPMS sensor attached to the valve stem; inspect for damage or corrosion.
If the sensor is faulty, replace it:
- Unscrew the valve stem cap.
- Remove the old sensor and replace it with a new one.
- Reattach the valve stem cap securely.

4. Recalibrate TPMS

Reconnect any electrical connectors that were removed during sensor replacement.
Follow the manufacturer’s instructions for recalibrating the system, which may involve turning the ignition on and off or using a TPMS tool.
Confirm that the TPMS warning light is no longer illuminated.

5. Road Test

Drive the vehicle for a short distance (approximately 10-15 minutes) to allow the system to update.
Check the dashboard to ensure the TPMS warning light has turned off.
