    Q:
    How to remove the MAP Sensor on Ford Fusion? Posted by Deyvin A.
    A:
    The MAP sensor's location for four-cylinder models can be found on the front left side of the block, above the starter motor, oil filter adapter, charge air cooler, or intake manifold. To remove, disconnect the negative battery terminal cable, the sensor's electrical connector, and the retaining bolt. Installation is the reverse.
