Solution

1. Preparation

Gather tools and parts required for the repair.
Tools Required: OBD-II scanner, tire pressure gauge, jack and jack stands, tire iron, TPMS tool (if replacing sensors).
Safety Warnings: Ensure the vehicle is on a level surface and turn off the engine before working on tires.

2. Tire Pressure Check and Adjustment

Remove valve caps from all tire valves.
Use a tire pressure gauge to check the pressure in each tire.
Inflate or deflate tires to the recommended PSI as indicated on the driver’s side door jamb.
Reinstall valve caps securely after adjustment.

3. Inspect and Replace TPMS Sensors

If TPMS sensors are faulty, raise the vehicle using a jack and secure it with jack stands.
Remove the tire from the rim using a tire iron and tire mounting tool.
Carefully detach the TPMS sensor from the valve stem.
Install the new TPMS sensor by attaching it to the valve stem and ensuring it is tightened.
Remount the tire and ensure it is sealed properly.

4. Reset TPMS System

Turn on the ignition without starting the engine.
Locate the TPMS reset button (usually under the steering wheel).
Press and hold the reset button until the TPMS light blinks three times, then release it.
Start the vehicle and allow the system to recalibrate, which may take a few minutes of driving.
