MAF Sensors Essentials

Air Mass Sensors (MAF) measure the volume of air drawn into the engine and then converts this data to signals which are transmitted to the Engine Control Unit (ECU). This data is used to determine the amount of fuel required for optimum combustion. In addition to data based on the volume of air, exact values are also transmitted for the intake air temperature, humidity, air density as well as the engine load. These are all essential for controlling a clean, environmentally friendly, combustion process.

Fault Codes & Diagnosis:
In some cases, no adverse conditions may be noticed by the driver. In other cases, there may be performance problems, such as a lack of power on acceleration, misfiring, trouble idling and diminished fuel economy.

For the entire system to work properly, all of the air entering an engine’s combustion chambers must be seen by the MAF sensor. This means that any vacuum or air leak (i.e. torn PCV hose, faulty PCV valve, torn Intake Air Boot etc.) may cause the engine to run rich or lean and cause the engine light to illuminate.

  1. Find and eliminate all external air or vacuum leaks and verify that the PCV valve is correctly installed and functioning correctly.
  2. The connector and the wiring at the Air Mass Sensor need to be checked for loose terminals, corrosion or damage.

Only after these steps have been completed should you direct your attention to the Air Mass Sensor itself.

Air Mass Sensors are very sensitive to contamination:
Fault codes are commonly the result of the Air Flow Sensor and the sensing wire getting covered with dirt, dust, or oil residue. Always make sure the Air Filter and its enclosure are dirt, dust, and oil-free. To prevent the air mass meter from failing prematurely, it is necessary for the filters to be replaced at manufacturers’ specified intervals. Cleaning the sensor is definitely not recommended as this usually results in damage to or destruction of the sensor.
