Air flow meter plays a major role of measuring the rate of intake airflow in a vehicle. This measurement is accomplished by measuring a little part of the complete flow. Electrical output signals are received by the ECU. These electrical signals are varied due to the quantity of heat that is emitting from hot film, which has been placed in the intake air stream. As this intake flows to the intake manifold through the path surrounding hot film, the generated heat by the hot film is carried away by air. Thus, minimization of heat depends a lot on airflow.

On most of vehicles, air flow meter is connected with air cleaner housing. Air flow meter is usually considered as a fancy variable resistor. A flap is placed inside air flow meter that deflects the amount of air entering the engine. This flap is connected with a wiper arm. A fixed voltage signal is send by ECU to air flow meter. There is improvement in the electrical resistance of air flow meter on opening of the flap. Thus, ECU can measure the amount of air entering the engine.

Air flow meter also comprises of one temperature sensor for intake air. Sensor is a semiconductor that varies resistance with temperature. For instance, if the temperature is higher then resistance will be lower. A fuel-pump safety switch is also incorporated in the air flow meter. On running of the engine, this fuel pump will operate. For instance, if the engine stopped due to accident, the fuel pump will be shut off by the airflow pump. This would prevent occurrence of fire.

In air flow meter there is also a provision for adjusting the mixture. Air flow meter housing also incorporates a screw. It is utilized as valve for air bypass channel. Air flow meter does not measure the air passing through the channel. Thus, it affects the air or fuel mixture. Mixture is made rich by turning screw clockwise, as it blocks off the channel. When the screw is turned counter clockwise, it opens the passage. Thus, leans the mixture.

If you want to replace the old air flow meter with new one then it will require a little effort. The replaced air flow meter must suit according to your car requirements. As a lot of time and money will be invested for appropriate searching of air flow meter, it would be better to opt for used air flow meter. Used air flow meter is available in pocket friendly prices. It is made up of high quality and guarantees durability and reliability.

Used air flow meter is available in varied range of styles and sizes through online catalogs. If you have any query regarding used air flow meter then call customer care representatives. They are available for 24 hours. These online catalogs also guarantee a safe and secure delivery of air flow meter at your doorstep.

Replacement of old air flow meter with new one will also maintain the original look of your favorite car. Get one air flow meter for your car and enjoy the looks and great ride.
