This video explains how the MAP Sensor works, MAP Sensor stands for: Manifold Absolute Pressure Sensor.
During the video we also illustrate how to test the MAP Sensor operation using a Vacuum Pump, a Hand Held Scanner and a Digital Volt Meter.
The reason we opted to show how to test the Sensor with a Digital Volt Meter is to enable viewers that may not own a Scanner to be able to test their Sensor and find out if it is defective.
This video is direct to the point and as simple as possible; that way any auto enthusiast can understand it, even if the person is just at an entry level.
