Solution

1. Preparation

Tools Required: OBD-II scanner, tire pressure gauge, jack and jack stands, torque wrench, tire iron.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the negative battery terminal for safety while working on electrical components.

2. Remove the Tire

Loosen the lug nuts on the wheel using a tire iron.
Use a jack to lift the vehicle and place it securely on jack stands.
Completely remove the loosened lug nuts and take off the tire.

3. Access and Replace the Tire Pressure Sensor

Locate the tire pressure sensor within the wheel assembly.
If necessary, remove the valve stem cap and unscrew the sensor from the valve stem using a wrench.
Carefully detach the sensor from the valve and replace the battery if applicable (if the sensor is serviceable) or proceed to install a new sensor.
Install the new sensor by attaching it to the valve stem securely.

4. Reinstall the Tire

Place the tire back onto the wheel hub and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and then torque the lug nuts to the manufacturer’s specifications (usually around 80-100 ft-lbs, but consult the vehicle's manual for exact values).

5. Reset the TPMS

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear any error codes and reset the TPMS system.
Alternatively, follow the owner's manual instructions to reset the TPMS using the vehicle's onboard menu.
