Solution

1. Preparation

Gather tools: OBD-II scanner (if needed), tire pressure gauge, jack, and tire iron.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Tire Pressure Adjustment

Remove the valve caps from each tire.
Measure the tire pressure using a tire pressure gauge.
Inflate or deflate each tire to match the recommended pressure found on the driver's side door jamb.

3. Sensor Inspection and Replacement

3.1. Remove Wheel Covers (if applicable)
- Use a tire iron to carefully pry off wheel covers if present.
3.2. Inspect TPMS Sensors
- Visually inspect each wheel for signs of damage to the TPMS sensor or valve stem.
- If damaged, remove the wheel and tire from the rim.
3.3. Replace Sensor
- Use a tire machine to demount the tire, exposing the TPMS sensor.
- Remove the old sensor and install a new TPMS sensor.
- Reassemble the tire onto the rim and ensure it is sealed properly.

4. Recalibration of TPMS

After replacing any sensors, reattach the wheel to the vehicle.
Turn on the vehicle and access the TPMS reset option in the vehicle’s settings.
Follow prompts to recalibrate the TPMS system, ensuring all sensors are recognized.
