In this video I show you how I test the MAP Sensor (Manifold Absolute Pressure Sensor). I explain the MAP sensor wiring diagram, then I locate all wires on the sensor itself. Then I explain how to diagnose a MAP sensor using a scan tool, and after that I show you how to test the MAP sensor using a multimeter. I check the sensor power supply and output voltage (signal) using a multimeter.
