Solution

1. Preparation

Gather tools: tire pressure gauge, OBD-II scanner, valve stem tool.
Ensure the vehicle is parked on a level surface with the ignition off.

2. Check and Adjust Tire Pressure

Sub-steps:
1. Remove valve caps from all tires.
2. Use the tire pressure gauge to measure the pressure in each tire.
3. Inflate or deflate tires to match the manufacturer’s recommended pressure, typically found on the driver’s door jamb.
4. Reinstall valve caps securely after adjusting pressure.

3. Inspect TPMS Sensors

Sub-steps:
1. Remove the tires from the rims if necessary to access the TPMS sensors.
2. Visually inspect each sensor for signs of damage or corrosion.
3. Clean the sensors if dirty, using a soft cloth and appropriate cleaner.
4. Replace any damaged sensors with new ones, ensuring they are compatible with the Ford F-150.

4. Reset TPMS System

Sub-steps:
1. Turn the ignition key to the "On" position without starting the engine.
2. Locate the TPMS reset button (usually below the steering column).
3. Press and hold the reset button until the TPMS light blinks three times and then turns off.
4. Start the engine and drive for a short distance to verify the reset was successful.
