DescriptionMAFS uses a hot-film type sensing element to measure the mass of intake air entering the engine, and send the signal to ECM.A large amount of intake air represents acceleration or high load conditions while a small amount of intake air represents deceleration or idle.
Circuit Diagram
InspectionOperating Logic Test (Manual only)Inspect the PTC operation by confirmation logic as follows.1.Entering(1)Set the Floor mode and maximum heating position.(2)Turn off the blower switch.(3)Press the intake (recirculation) button 5 times or more.
Inspection1.Turn the ignition switch OFF.2.Disconnect the mode control actuator connector.3.Verify that the mode control actuator operates to the defrost mode when connecting 12V to terminal 3 and grounding terminal 4.Verify that the mode control actuator operates to the vent mode when connected in reverse.
