Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and eyewear.

2. Resetting the TPMS

Locate the TPMS reset button: This is usually found under the steering wheel or in the glove box. Refer to the owner's manual for exact location.
Turn the ignition on: Do not start the engine; just turn the key to the "On" position.
Press and hold the TPMS reset button: Hold the button until the TPMS warning light blinks three times, then release it.
Wait for the system to recalibrate: Drive the vehicle for approximately 10-30 minutes at speeds above 50 mph to allow the system to recalculate the tire pressures.

3. Replacing TPMS Sensors (if needed)

Remove the wheel: Loosen the lug nuts and lift the vehicle with a jack. Remove the wheel.
Remove the tire from the rim: Use a tire machine or manual tools to carefully separate the tire from the rim.
Replace the TPMS sensor: Remove the old sensor from the valve stem and replace it with a new one, ensuring it is properly secured.
Reinstall the tire: Mount the tire back onto the rim and ensure it is seated properly. Inflate to the recommended PSI.
Reattach the wheel: Place the wheel back on the vehicle and torque the lug nuts to the manufacturer’s specifications.
