    Q:
    How to remove and install the Intake Air Temperature Sensor and Mass Air Flow Sensor on the air intake duct of a Ford Fusion? Posted by Bruwil T.
    A:
    To remove the Mass Air Flow (MAF)/Intake Manifold Temperature (IMT) start by removing the air intake duct and disconnecting the electrical connector from the MAF/IMT sensor. Remove the MAF/IMT sensor mounting fasteners and remove the sensor from the air filter housing. Installation is the reverse of removal.
