More and more car owners are trying to maintain their cars on their own. This results in considerable cost savings because modern cars require more and more routine service and are made up of more and more technical components that lead to new breakdowns or inconveniences. One of the complications that impacts more and more Volkswagen Atlas owners is a clogged air flow meter, which will result in a loss of power and black exhaust fumes. Today we are going to examine how to clean the mass air flow sensor of your Volkswagen Atlas? . First, we will show you how your mass airflow sensor works and its advantages, second, why it may be important to clean this sensor , and at last, how to clean the mass air flow sensor of a Volkswagen Atlas .
Utility and action of the mass air flow meter of a Volkswagen Atlas
.
So we start our article with the operation and goal of your Volkswagen Atlas flowmeter.
The aim of the mass air flow sensor on Volkswagen Atlas
The mass air flow sensor is a part that has been developed quite lately and specifically supplied on diesel models. Indeed, with injection engines, the fuel and air intake has become very precise and it is consequently necessary for the ECU to know the exact volume of air injected into the engine to adapt the actions of complementary intake parts such as the injection or the EGR valve, if you have problems with the EGR valve on your Volkswagen Atlas, do not think twice to seek advice from our article on this subject.

- Once taken apart, you will have the ability to move forward to the step cleaning the mass air flow sensor of your Volkswagen Atlas . This sensor will, with time, 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 disturb the operation of the engine of your Volkswagen Atlas. The aim of this cleaning will be to remove all its harmful particles to allow it to work efficiently again.
- Let soak the lower section of your mass air flow sensor (not the plug part) in acetone or another solvent for a few minutes , which will remove most of the grime
- Now we’ll proceed to the very delicate cleaning of the flow meter filaments. You have to be very cautious, in any other case your mass air flow sensor will be permanently broken. 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 as well 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 Atlas , you should feel a noticeable difference in the behavior of your engine.
