More and more car owners are trying to take care of their vehicles by themselves. This results in significant cost savings because contemporary cars require more and more routine service and are done up of more and more technical components that lead to new breakdowns or inconveniences. One of the complications that disturbs more and more Nissan Pathfinder owners is a clogged air flow meter, which will bring about a loss of power and black exhaust gases. In this article we are going to take a look at how to clean the mass air flow sensor of your Nissan Pathfinder? . First, we will describe how your mass airflow sensor operates and its value, second, why it may be important to clean this sensor , and at last, how to clean the mass air flow sensor of a Nissan Pathfinder .

Utility and operation of the mass air flow meter of a Nissan Pathfinder

.
So we start our content page with the operation and role of your Nissan Pathfinder flowmeter.

The goal of the mass air flow sensor on Nissan Pathfinder

The mass air flow sensor is a part that has been created actually quite lately and principally supplied on diesel models. In fact, 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 added into the engine to change the actions of complementary intake parts such as the injection or the EGR valve, if you have problems with the EGR valve on your Nissan Pathfinder, do not think twice to consult our content page on this subject.

Mass air flow sensor operation on Nissan Pathfinder

  • Once disassembled, you will have the ability to carry on to the step cleaning the mass air flow sensor of your Nissan Pathfinder . 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 have the ability to collect data accurately, it is in this sense that it will disrupt the operation of the engine of your Nissan Pathfinder. The goal of this cleaning will be to remove all its harmful particles 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 remove most of the grime
  • .

  • Now we’ll proceed to the very gentle cleaning of the flow meter filaments. You have to be very watchful, otherwise your mass air flow sensor will be permanently damaged. 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 damaging 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 Nissan Pathfinder , you should feel a noticeable difference in the behavior of your engine.
