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
DescriptionThe mode control actuator is located at the heater unit.It adjusts the position of the mode door by operating the mode control actuator based on the signal of the A/C control unit. Pressing the mode select switch makes the mode control actuator shift in order of Vent → Bi-Level → Floor → Mix.
Inspection1.Connect the battery voltage and check the blower motor rotation.2.If the blower motor does not operate well, substitute with a known-good blower motor and check for proper operation.3.Replace the blower motor if it is proved that there is a problem with it.
