What are the features and testing procedures for the Mass Air Flow Sensor on 1991 Volvo 780?

The sensor of the air mass meter keeps a wire at 250 degrees higher temperature than the ambient air. Increased air mass means more current which is consumed to perform calculations. Testing is done for resistance and voltage. For removal, disconnect the battery, unplug the sensor and unscrew it. Reinstallation is the reverse of installation.
