Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Safety warning: Always wear safety gloves and goggles when working on tires.

2. Check and Inflate Tires

Use a tire pressure gauge to check the pressure of all tires.
Inflate any low tires to the manufacturer-recommended pressure, found on the driver’s door jamb label.

3. Replace Faulty TPMS Sensors

Tools Required: Tire iron, TPMS sensor tool, socket set.
Remove the tire from the wheel using a tire iron.
Unmount the tire from the rim using a tire machine or manually if equipped.
Remove the old TPMS sensor from the wheel by loosening the retaining nut.
Install the new TPMS sensor, ensuring it is properly seated and the retaining nut is tightened to the manufacturer's specifications (usually around 4-5 Nm).
Remount the tire onto the wheel and balance it if necessary.

4. Reset TPMS

Start the vehicle and follow the manufacturer's procedure to reset the TPMS, which may involve using the vehicle’s infotainment system or a dedicated TPMS reset tool.
Confirm that the TPMS warning light on the dashboard turns off.
