my Ford Explorer's tire pressure light keeps coming on, what does it mean

Solution

1. Preparation

• Tools Required: Tire pressure gauge, OBD-II scanner, jack and jack stands, tire repair kit (if necessary).
• Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
• Wear safety gloves and goggles.

2. Check and Adjust Tire Pressure

• Sub-steps:
  1. Remove the valve stem caps from each tire.
  2. Use the tire pressure gauge to measure the pressure of each tire.
  3. Refer to the vehicle’s owner manual or sticker on the driver’s door jamb for the recommended tire pressure.
  4. Inflate or deflate tires as needed to match the recommended pressure.
  5. Reinstall valve stem caps securely.

3. Inspect Tires for Damage

• Sub-steps:
  1. Visually inspect each tire for punctures, cuts, or bulges.
  2. Check for uneven wear patterns which may indicate alignment issues.
  3. If damage is detected, replace the tire or repair as necessary.

4. TPMS Sensor Check

• Sub-steps:
  1. Connect the OBD-II scanner to the vehicle’s diagnostic port.
  2. Retrieve any TPMS-related fault codes.
  3. Follow troubleshooting procedures based on the retrieved error codes.
  4. If necessary, replace faulty TPMS sensors.

5. Reset the TPMS

• Sub-steps:
  1. Turn the ignition to the "ON" position without starting the engine.
  2. Use the TPMS reset button (typically located under the steering wheel or in the glove compartment) to reset the system.
  3. Follow the procedure as outlined in the owner’s manual to ensure the system recognizes the new tire pressures.
