Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the tires are at the recommended pressure.
Disconnect the 12V battery to prevent electrical issues during the repair.

2. Remove Wheel

Loosen the lug nuts on the affected wheel with a lug wrench.
Safely lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Access and Replace TPMS Sensor

Locate the tire pressure sensor mounted on the inside of the tire rim.
Remove the valve stem nut using a socket wrench and carefully detach the sensor from the rim.
Install the new TPMS sensor by attaching it to the valve stem and securing it with the nut. Torque the nut to the manufacturer's specification (typically around 5-7 Nm).

4. Reassemble Wheel

Reinstall the wheel onto the hub, ensuring it is properly aligned.
Hand-tighten the lug nuts before lowering the vehicle.
Once the vehicle is on the ground, use the torque wrench to tighten the lug nuts to the manufacturer's specification (usually 100-110 Nm).

5. Reset TPMS

Reconnect the 12V battery.
Power on the vehicle and navigate to the TPMS reset function in the settings menu.
Follow the on-screen instructions to recalibrate the TPMS system.
