Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Gather safety equipment, including gloves and safety glasses.

2. Check Tire Pressure

Remove valve caps from each tire.
Using a tire pressure gauge, measure the pressure in each tire.
Inflate or deflate tires to match the recommended pressure found on the driver’s side door jamb.

3. Inspect and Replace TPMS Sensors

Tools Required: Tire iron, jack, jack stands, TPMS sensor tool, socket set.
Lift the vehicle using a jack and securely place it on jack stands.
Remove the wheel using the tire iron.
Inspect the TPMS sensor attached to the valve stem for damage or corrosion.
If a sensor is damaged, remove the old sensor by unscrewing it from the valve stem.
Install the new TPMS sensor by screwing it onto the valve stem and ensuring it is secure.

4. Reset TPMS

Turn the ignition key to the "ON" position (do not start the engine).
Locate the TPMS reset button usually located beneath the steering wheel or in the glove compartment.
Press and hold the reset button until the TPMS light blinks three times and then turns off.
Start the vehicle and allow it to run for about 20 minutes to complete the reset.

5. Final Inspection

Reinstall the wheel and torque the lug nuts to the manufacturer's specifications (typically 76 ft-lbs).
Lower the vehicle back to the ground and recheck tire pressures.
Test drive the vehicle to ensure TPMS warning light is off and sensors are functioning correctly.
