What is a Mass Air Flow Meter Sensor & How Does It Work?

The mass air flow meter sensor (MAF) might be small in size, but its role in your vehicle’s electronic fuel injection system is nothing short of crucial. Located between the air filter and the throttle body, the MAF sensor measures the rate of air flowing into the engine and provides essential data for calculations of the right fuel-to-air ratio for efficient combustion.

Most modern vehicles use a hot wire MAF air flow meter sensor, which consists of a heated wire and an ambient temperature wire. A microprocessor embedded within the air flow meter sensor maintains the temperature of the hot wire at a specific level above the ambient air temperature. By measuring the energy required to maintain this temperature, the air flow meter sensor calculates the airflow entering the engine where this information is then relayed to the ECU, which adjusts the fuel injection accordingly.

FAQ

1. Why does my car need a mass airflow meter sensor?

The mass airflow meter sensor measures the air mass, which flows through the air filter to the engine. The data is then sent to the control unit in order to specify the injection rate of the fuel. The combustion engine requires 14,7 kg of air for the optimal combustion of 1kg of fuel. In order to regulate the correct proportion of fuel and air in any operational condition, the engine control unit requires the exact information concerning the intake of the air mass. The mass airflow sensor plays an integral part in the reduction of exhaust and air supply.

2. What does a mass airflow meter sensor consist of?

A mass airflow meter sensor consists of a case which is positioned between the air filter and air pipe. The sensor is either screwed or firmly attached inside the case. The sensor in turn includes a hot film meter and electronics. The sensor measures the air which flows to the engine through the air filter and sends the data to the control unit.

3. Can it be useful to get break cleaner or other cleaning material to clean the mass airflow sensor meter?

The air flow meter membrane may be severely damaged by the clean up. Never apply compressed air as this may also damage the sensor.

4. Is there a difference between air volume sensor and mass airflow sensor meter?

No. Air volume sensors and mass airflow meter sensors refer to the same item. Other terms are hot film meter, HFM, airflow meter sensor, MAF or MAFS.
