2. Tire Pressure Adjustment

Check and inflate each tire to the recommended PSI found on the driver’s door jamb sticker.
Use a reliable tire pressure gauge to ensure accuracy.

3. Sensor Inspection and Replacement

Remove Tire if Necessary
- Use a jack to lift the vehicle off the ground.
- Secure the vehicle with jack stands.
- Remove the wheel nuts with a socket set and take off the wheel.
Inspect TPMS Sensor
- Locate the TPMS sensor mounted on the valve stem.
- Check for physical damage or signs of battery leakage.
- If damaged, proceed to replace the sensor.
Replace TPMS Sensor
- Remove the old sensor by unscrewing it from the valve stem.
- Install the new TPMS sensor, ensuring it is securely attached.
- If applicable, ensure to activate the new sensor using a TPMS tool.
Reinstall the Wheel
- Place the wheel back on the hub.
- Hand-tighten the wheel nuts, then use a torque wrench to tighten them to the manufacturer’s specified torque.

4. Resetting TPMS

Start the vehicle and let it run for a few minutes.
Follow the manufacturer’s procedure to reset the TPMS, typically involving pressing the TPMS reset button located under the steering column or in the glove box, or using the vehicle's infotainment system.
