why does my Ford Explorer's tire pressure light stay on

Solution

1. Preparation

• Gather Tools: Tire pressure gauge, OBD-II scanner, jack and jack stands, tire patch kit (if necessary).
• Safety Warning: Ensure the vehicle is parked on a flat surface and the engine is off before starting work.

2. Check and Adjust Tire Pressure

• Sub-steps:
  1. Remove the valve caps from all tires.
  2. Use the tire pressure gauge to measure each tire's pressure.
  3. Inflate or deflate the tires to match the manufacturer's recommended pressure (usually found on the driver’s door jamb).
  4. Replace all valve caps securely.

3. Inspect and Repair Tires

• Sub-steps:
  1. Examine each tire for visible damage, such as cuts or punctures.
  2. If a puncture is found, use a tire patch kit to repair it or replace the tire if damage is severe.
  3. Ensure all tires are properly seated on the rims.

4. Reset the TPMS

• Sub-steps:
  1. Turn the vehicle's ignition to the "On" position without starting the engine.
  2. Press and hold the TPMS reset button (usually located under the steering column or in the glove box) until the TPMS light blinks three times.
  3. Start the vehicle and allow it to run for a few minutes to verify that the light resets.

5. Replace TPMS Sensors (if necessary)

• Sub-steps:
  1. If the TPMS sensors are non-functional, remove the tires from the wheels using a tire changer.
  2. Replace the faulty sensors with new ones, ensuring they are compatible with the vehicle.
  3. Reinstall the tires, balancing them as necessary.
