Solution

1. Preparation

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

2. Inspect and Replace TPMS Sensors

Tools Required: Tire iron, jack, TPMS tool, socket set, torque wrench.
Safely lift the vehicle using a jack and secure it with jack stands.
Remove the wheel using a tire iron.
Use a TPMS tool to remove the old sensor from the valve stem.
Install a new TPMS sensor, ensuring it is correctly seated. Tighten the retaining nut to the manufacturer’s specified torque (generally 3-4 Nm).
Reinstall the wheel and lower the vehicle.

3. Reset the TPMS System

With the vehicle's ignition on (but not running), press the TPMS reset button (if equipped) until the TPMS light blinks three times.
Alternatively, drive the vehicle for about 20 minutes above 50 mph to allow the system to recalibrate.

4. Monitor Tire Pressure

After replacing the sensors and resetting the system, monitor the tire pressure using a tire pressure gauge.
Ensure all tire pressures are at the recommended levels (usually found on the driver’s door jamb).
