This could be a small block or a cylindrical section mounted as part of the air duct. On some models, you''ll ...

A mass air flow sensor monitors the air coming in through the air intake system so that the vehicle''''s electronic control unit (ECU) can make adjustments to the air/fuel ratio. Adjustments to the fuel mixture are necessary to keep a vehicle running smoothly. Too much air and not enough fuel will cause the engine to run lean, causing the vehicle to potentially stall. Too much fuel, however, and ...

MAF Sensor Testing The TechAssist Team It’s always a good idea to test a Mass Airflow (MAF) sensor before replacing it.
