More and more car owners are trying to maintain their cars by themselves. This results in substantial savings because modern cars involve more and more maintenance and are made up of more and more technical parts that lead to new breakdowns or inconveniences. One of the problems that impacts more and more Fiat Grande Punto owners is a clogged air flow meter, which will bring about a loss of power and black exhaust fumes. Today we are going to take a look at how to clean the mass air flow sensor of your Fiat Grande Punto? . First, we will show you how your mass airflow sensor functions and its usefulness, second, why it might be important to clean this sensor , and at last, how to clean the mass air flow sensor of a Fiat Grande Punto .

.
So we start our content page with the procedure and purpose of your Fiat Grande Punto flowmeter.
The goal of the mass air flow sensor on Fiat Grande Punto
The mass air flow sensor is a part that has been developed actually quite not too long ago and mainly equipped on diesel models. In actual fact, with injection engines, the fuel and air intake has become very precise and it is so important for the ECU to know the exact volume of air injected into the engine to adapt the behaviour of complementary intake parts such as the injection or the EGR valve, if you have problems with the EGR valve on your Fiat Grande Punto, do not think twice to seek advice from our content page on this subject.

The goal of this cleaning will be to remove all its harmful particles to allow 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 remove most of the grime
- Now we’ll proceed to the very gentle cleaning of the flow meter filaments. You have to be very cautious, in any other case 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 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 Fiat Grande Punto , you should feel a noticeable difference in the behavior of your engine.
