With the mass air flow cleaner and tools in hand, locate the maf sensor in the air duct between the air filter box and the throttle body. There are several types found on vehicles today. Hot wire or hot film.

The air mass information is necessary for the ecu to correctly balance and deliver the correct amount of fuel to the engine. It's as if there were a time lag between when the accelerator pedal is depressed and engine reaction. By passing a current through a wire and measuring the change of resistance of the wire the ecu can measure how much air is entering the engine at a given time.

You will also usually be able to see dirt or grime on the maf just from opening your hood and looking at it. You will know your maf (mass air flow) is dirty from either noticing a decrease in gas mileage, power, or just an overall less smooth ride in your car. A mass airflow sensor (mas) determines the mass of air entering a vehicle's fuel injection engine, and passes that data to the engine control unit, or ecu.

You may notice an occasional hiccup where it feels like the car missed a beat. Mass air flow sensor problems problems mass air flow sensors are very common. How to clean nissan maf sensor.
