How to Clean a Ford Windstar Mass Air Flow Sensor

The mass air flow sensor on your Ford Windstar is designed to measure the amount of air that comes in through the intake, which allows the computer to adjust the fuel pressure and flow accordingly. If the sensor is dirty, then it's not going to read the correct data, which could cause the engine to run poorly. Cleaning the mass air flow sensor is easily done with just a few tools and the right cleaners.

Things You'll Need

  • Phillips-head screwdriver
  • Mass air flow sensor cleaner


    • 1

      Pop the hood and locate the mass air flow sensor. It's located between the air filter and the throttle body, and has a wiring harness plugged into it. Unplug the harness, using your hands.

      Unscrew the hose clamps on both sides of the mass air flow, using the flathead screwdriver. Pull out the sensor, with your hands.

    • 3

      Spray the mass air flow sensor cleaner in the center of the mass air flow sensor. You want to spray it all over the surface, using the pressure from the spray to blast off the dirt and grime on the inside of the sensor. Once you've finished spraying, allow the sensor to air dry for at least one hour.
