Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to prevent electrical issues.

2. Check and Inflate Tires

Remove the valve caps from each tire.
Use a tire pressure gauge to measure the pressure of each tire.
Inflate or deflate tires to match the recommended pressure (found on the driver’s door jamb).
Replace the valve caps securely.

3. Inspect and Replace TPMS Sensors

Remove the wheel covers or hubcaps if applicable.
Use a tire machine to demount the tire from the rim if sensor replacement is necessary.
Locate the TPMS sensor; it is usually attached to the valve stem.
Disconnect the sensor from the valve stem and replace it with a new sensor, ensuring it is properly seated.
Reassemble the tire and remount it on the wheel.

4. Reset the TPMS

Reconnect the negative battery terminal.
Turn the ignition to the "ON" position without starting the engine.
Press and hold the TPMS reset button (usually located under the steering wheel) until the TPMS light blinks three times, indicating a reset.
Start the vehicle and confirm that the TPMS warning light is no longer illuminated.
