What Does a Performance Mass Air Flow Sensor Do? What Does a Mass Air flow Sensor Do? Your mass air flow sensor or “MAF” detects the volume of air as it enters your engine by heating up a thin wire or resistor. The computer in your car then measures electrical resistance through the MAF as the air flowing through the sensor cools its components down. With a firm understanding of how much air is flowing into your engine, the computer can then direct fuel injectors to add more or less gasoline to the air/fuel mixture.

Includes aluminum surface mounting bracket with screws, (2) 5 ft (1.5 m) lengths of 1/4 aluminum tubing, (2) static pressure tips & (2) molded plastic vent valves.here are two ways to measure air flow in process ducts. The most common means is the use of a Series 2000 Magnehelic® Differential Pressure Gage. This gage can be ordered with a square root output that will read in flow units. You will have to specify the maximum differential pressure at your desired flow rate.

Mass Air Flow Sensor The majority of vehicles on the road today are equipped with a mass air flow sensor (MAF), also commonly referred to as an air flow meter. The mass air flow sensor is a device that measures the amount of air entering the engine and supplies this information to the engine control unit (ECU).ot Wire Mass Air Flow Sensors. One of the more common mass air flow sensors used today is the hot wire sensor. This type of MAF sensor measures air mass directly. It uses an electronic control unit, a temperature sensor, and an electronically heated wire(s).

- The mass air flow (MAF) sensor measures the mass of the air entering the engine. Because air mass varies with air temperature (cold air is denser than warm air), measuring air mass provides the PCM with a very acurate way of determining the correct amount of fuel to obtain the ideal fuel/air mixture.fter you clean the mass air flow sensor make sure to reset the check engine light. You can reset your check engine by going to Auto Zone or Kragen Auto Parts and ask to borrow the code reader* (it's free all you need is your ID and credit card) to check out the code reader.

How does the Lambda sensor work? In order to achieve this an engine needs to attain as close to complete combustion as possible. The ideal ratio of air and fuel to achieve this is around 14.7:1; this means that for 14.7 kg of air 1 kg of fuel would be used. This chemically correct air fuel ratio is known as a stoichiometric ratio or Lambda (λ)1.0. A fuel rich mixture would have a lower value e.g. 0.8 and a fuel lean mixture would have a higher value e.g. 1.2.

What Are Some Symptoms of a Bad Mass Air Flow Sensor? Full Answer. The MAF sensor uses the temperature difference between the coolant and air entering the fuel mix to determine airflow. Under normal circumstances, the temperature of the air is a few degrees cooler than the coolant. If the sensor is bad and displays a temperature higher than the coolant level, the engine-control unit reduces the fuel flow, resulting in a lean operating condition that decreases fuel economy.

Mass flow sensor If air density increases due to pressure increase or temperature drop, but the air volume remains constant, the denser air will remove more heat from the wire indicating a higher mass airflow. Unlike the vane meter's paddle sensing element, the hot wire responds directly to air density.

- Below is a list of all the needed sensors to install a MAF TPI setup, and each of their functions. Mass Air Flow (MAF) Sensor: This sensor is responsible for measuring air volume and density. It is located in the air duct, before the throttle body. All of the air that the engine consumes must first pass through the MAF sensor. At the center of the MAF, is a very thin wire whose resistance increases as it goes up in temperature.

What a Mass Airflow Meter Does and How to Maximize Your Car's Performance The Mass Airflow Meter is an air flow sensor, also known as a MAF sensor, and is an integral component of the computer controlled engine system found on most modern cars.n most applications, the MAF sensor utilizes an electrically charged wire to determine the amount of airflow entering the air intake. This wire produces an electrical voltage, based on airflow, and sends it to the engine computer, which then uses the information to adjust spark timing, fuel delivery and spark advance.
