Map Sensor Testing Ford. MAP Sensor Code Won't Go Away. When issues emerge, the vacuum hose is most likely to blame. This powers up the sensors in your engine bay, and allows you to check for operation. What Does a Map Sensor Do? A manifold absolute pressure (MAP) sensor senses air pressure or vacuum in the intake manifold. Depending on your installation, the sensor attaches to the intake manifold through a rubber hose; otherwise, it connects directly to the intake. You can just blow into the tube that connects to the intake and watch the pressure change on your monitor – if the tube and sensor are in good order, of course. Preliminary Check Make a preliminary check before testing a MAP sensor.
