Utility and operation of the mass air flow meter of a Mercedes Classe C 4

.
So we start our article with the process and role of your Mercedes Classe C 4 flowmeter.

The intent of the mass air flow sensor on Mercedes Classe C 4

The mass air flow sensor is a part that has been created quite not long ago and mainly equipped on diesel models. In truth, with injection engines, the fuel and air intake has become very precise and it is consequently essential for the ECU to know the exact volume of air loaded into the engine to modify the behaviour of complementary intake parts such as the injection or the EGR valve, if you have problems with the EGR valve on your Mercedes Classe C 4, do not hesitate to seek advice from our article on this subject.

Mass air flow sensor operation on Mercedes Classe C 4

Now, we are going to take a look at how it works, before trying to clean the mass air flow sensor of your Mercedes Classe C 4 , you must already figure out how it works to achieve this routine service work accurately.

You should know that this operation is quite basic to execute and you will not need advanced mechanical expertise to do it yourself, a good method to avoid a trip to the workshop and a steep bill. See down below the different steps to stick to to execute this routine service act:

  • After having located the mass air flow sensor of your Mercedes Classe C 4 , you will have to dismantle it. To get this done, work gently, but you will just have to disassemble it on both sides of the air duct and detach the electrical plug on top of it.
  • Once disassembled, you will be able to carry on to the step cleaning the mass air flow sensor of your Mercedes Classe C 4 . This sensor will, over 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 be able to collect data accurately, it is in this sense that it will disrupt the operation of the engine of your Mercedes Classe C 4. 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 section 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 move on to the very delicate cleaning of the flow meter filaments. You have to be very watchful, otherwise your mass air flow sensor will be permanently broken. With the help of a fine brush and solvent, gently clean the two filaments of your mass air flow sensor . If you are too afraid of harming 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 Mercedes Classe C 4 , you should feel a noticeable difference in the behavior of your engine.
