Utility and operation of the mass air flow meter of a Volkswagen Routan

.
So we begin our content with the procedure and aim of your Volkswagen Routan flowmeter.

The intent of the mass air flow sensor on Volkswagen Routan

The mass air flow sensor is a component that has been created quite not long ago and specifically outfitted on diesel models. Indeed, with injection engines, the fuel and air intake has become very precise and it is therefore necessary for the ECU to know the exact volume of air added into the engine to change the behaviour of complementary intake parts such as the injection or the EGR valve, if you have problems with the EGR valve on your Volkswagen Routan, do not hesitate to consult our content on this subject.

Mass air flow sensor operation on Volkswagen Routan

Now, we are going to have a look at how it operates, before trying to clean the mass air flow sensor of your Volkswagen Routan , you must already find out how it functions to do this maintenance work correctly.

  • Once taken apart, you will have the ability to carry on to the step cleaning the mass air flow sensor of your Volkswagen Routan . This sensor will, as time passes, get dirty and its two “filaments” that will give information to your computer on the quality and temperature of the air will no longer have the ability to collect data correctly, it is in this sense that it will affect the operation of the engine unit of your Volkswagen Routan. The intent of this cleaning will be to take out all its impure substances to enable it to work efficiently again.
  • Let soak the lower part of your mass air flow sensor (not the plug part) in acetone or another solvent for a few minutes , which will take out most of the grime
  • .

  • Now we’ll proceed to the very delicate cleaning of the flow meter filaments. You have to be very careful, otherwise your mass air flow sensor will be permanently damaged. With the help of a fine brush and solvent, delicately clean the two filaments of your mass air flow sensor . If you are too afraid of destroying it, you can also clean them with a brake fluid in the form of an aerosol by spraying the jet on these filaments.

Now you know how to clean the mass air flow sensor of your Volkswagen Routan , you should feel a noticeable difference in the behavior of your engine unit.
