MAF transfer data is the relationship of ______ flow as it corresponds to the MAF sensor signal voltage.

MAF transfer data is the relationship of ______ flow as it corresponds to the MAF sensor signal voltage.

• A. Mass Air
• B. Mass Volume
• C. Air Flow
• D. Fuel Flow

Answer: (A)

The idea being tested is how the MAF sensor’s voltage corresponds to the amount of air entering the engine. The MAF measures mass of air flow, not volume or fuel, so the transfer data describe how mass air flow relates to the sensor’s voltage output. That’s why “Mass Air” is the best completion, giving the familiar phrase mass air flow. The other options don’t fit because they describe volume, a general “air flow” term without specifying mass, or fuel flow, which isn’t what the MAF measures.
