Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked on a level surface.
Wear safety gloves and goggles.

2. Inspect and Adjust Tire Pressures

Remove the valve stem caps from each tire.
Use a digital tire pressure gauge to measure the pressure in each tire.
Inflate or deflate the tires as necessary to match the manufacturer’s recommended pressures (found on the driver’s door jamb).
Replace the valve stem caps securely.

3. Reset TPMS

Turn on the vehicle without starting the engine.
Navigate to the vehicle settings on the infotainment display.
Select the TPMS settings and choose the option to reset or recalibrate the system.
Confirm the reset and turn off the ignition.

4. Replace TPMS Sensors (if needed)

If any sensors are faulty, lift the vehicle using a jack and secure it with jack stands.
Remove the wheel with the faulty sensor using a socket set.
Detach the tire from the rim using a tire changer.
Replace the faulty TPMS sensor with a new one, ensuring it is properly seated.
Reinstall the tire onto the rim, ensuring it is sealed correctly.
Reattach the wheel and torque the lug nuts to the manufacturer’s specifications.
