Does anyone know how to test the MAP sensor?

As far as I know, there's not really a test listed in the Chiltons manual or the FSM. There is a good description of the MAP sensor in the FSM, that will clue you in on how to test it. It gets 5v from the ECU. The ECU reads the voltage before starting the engine, and then adjusts shit depending on what it is while the engine is running.
