What does a Mass Airflow Sensor do?

The mass airflow sensor measures the amount of air entering the air inlet. The engine's computer will process this information and adjust the amount of fuel injected into the engine accordingly, to ensure that an optimal fuel to air mixture enters the cylinder for combustion. The system is important to reduce fuel consumption as well as emissions. The sensor is usually located right behind the air inlet and filter and is mounted in a detachable unit usually made from plastic.

Over the years there have been several types of air flow meters, some make use of a spring-loaded vane, some feature a membrane. Again others make use of a thin hot wire through which an electric current flows, as the air flow over the wire increases the wire becomes colder, resistance decreases leading to more electricity flowing through the wire which inform the ECU about the amount of air coming into the engine.

How do you know there is something wrong with the Mass Airflow Sensor?

  • When the 'Check Engine' light on your dashboard is on.
  • When the engine won't start or cuts out during operation.
  • When the engine misfires.
  • When the engine runs rough (a rough idle for example).
  • When the engine doesn't perform as well as usual.
  • When the car's fuel consumption is higher than usual.

When should you consider a Mass Airflow Sensor replacement?

Over time, the sensor can become soiled due to dirty air flowing past the sensor (usually due to a dirty air filter). This diminishes the sensor's ability to regulate the amount of air flowing through. In turn eading to the ECU being unable to regulate the fuel injected into the engine according to the actual amount of air flowing in. This can lead to a variety of issues; a lean or rich running engine, high fuel consumption and so on.

For optimal combustion cycles in the engine it is therefore important to service the mass airflow sensor as and when stipulated in the guidelines set out by your car's manufacturer. Professional and timely maintenance is essential to prevent further damage of other parts of the engine. Should you experience problems with the mass airflow sensor, then it is advisable to have it inspected and, if necessary, have the sensor replaced.

What happens during a Mass Airflow Sensor replacement?

  • The mechanic will read the ECU for possible fault codes related to the sensor.
  • The mechanic will inspect the sensor and ancillaries (like the vacuum hoses).
  • If necessary, the mechanic will replace the sensor.
  • The mechanic will check the system again and will test drive the car to ensure proper operation of the engine.
  • If necessary the mechanic will make adjustments.
