Where is the map sensor located on a 2001 Mazda protege 1.6?

The manifold absolute pressure (MAP) sensor on a 2001 Mazda Protege 1.6 is located on the intake manifold, just below the throttle body. It is a small, round sensor with a vacuum hose connected to it. The MAP sensor measures the air pressure in the intake manifold, and this information is used by the engine control unit (ECU) to calculate the air/fuel mixture and ignition timing.
