Solution

1. Prepare the Vehicle

Ensure the vehicle is parked on a level surface and the engine is turned off.
Gather necessary tools: tire pressure gauge, OBD-II scanner (if troubleshooting sensor issues).

2. Inflate Tires

Check and adjust the tire pressures of all four tires to the manufacturer's recommended PSI found on the driver’s side door jamb.
Allow a few minutes for the TPMS to recognize the new pressures.

3. Reset the TPMS

Turn the ignition to the "ON" position without starting the engine.
Press the gas pedal three times within 10 seconds.
Turn the ignition off and then back to the "ON" position.
The TPMS light should blink and then turn off, indicating a successful reset.

4. Verify Functionality

Start the engine and check that the TPMS light remains off during the vehicle's operation.
Drive the vehicle for a few minutes to ensure that the system recognizes the correct tire pressures.
