Solution

1. Preparation

Gather tools and parts needed.
Ensure the vehicle is parked on a flat surface.
Disconnect the negative battery terminal for safety.

2. Replace TPMS Sensors (if faulty)

Lift the Vehicle: Use a jack to elevate the vehicle and secure with jack stands.
Remove Wheels: Use a socket set to remove lug nuts and take off the wheels.
Access TPMS Sensors:
- Use a tire iron to break the bead of the tire on the wheel.
- Carefully remove the tire from the rim to access the sensor.
Replace Sensors:
- Detach the old sensor from the valve stem.
- Install the new TPMS sensor onto the valve stem and ensure it is secured.
Reinstall Tire: Carefully mount the tire back onto the rim and ensure a proper bead seat.
Reattach Wheels: Mount the wheel back onto the vehicle and tighten lug nuts to the manufacturer’s torque specification.

3. Reinitialize TPMS

Reconnect Battery: Reconnect the negative battery terminal.
Use the TPMS Tool: Follow the vehicle’s service manual to reprogram or sync the new sensors with the vehicle’s TPMS system.
Check for Fault Codes: Use the OBD-II scanner to ensure no fault codes remain.
