I checked the map sensor with a volt meter. I checked 5 volts coming to sensor from pcm when car was turned off. Then I checked voltage again with car running and it dropped down to 1.5 volts this indicates that the map sensor is good. I found a video on you tube that shows you how to check it.

Watch "Map Sensor Testing" on YouTube
