More and more motorists are trying to maintain their cars on their own. This outcomes in considerable savings because modern cars require more and more maintenance and are done up of more and more technical parts that result in new breakdowns or inconveniences. One of the problems that affects more and more Fiat 500 L owners is a clogged air flow meter, which will lead to a loss of power and black exhaust fumes. Today we are going to look at how to clean the mass air flow sensor of your Fiat 500 L? . 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 Fiat 500 L .
Utility and operation of the mass air flow meter of a Fiat 500 L
.
So we start our content with the operation and intent of your Fiat 500 L flowmeter.
The goal of the mass air flow sensor on Fiat 500 L
The mass air flow sensor is a component that has been created quite not long ago and principally supplied on diesel models. In actual fact, with injection engines, the fuel and air intake has become very precise and it is so essential for the ECU to know the exact volume of air loaded 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 500 L, do not think twice to consult our content on this subject.
Mass air flow sensor operation on Fiat 500 L
Now, we are going to look at how it works, before trying to clean the mass air flow sensor of your Fiat 500 L , you must already understand how it functions to achieve this maintenance work properly.
The mass air flow sensor is consequently principally there to get info on the air intake of your car. To achieve this, it must be set up just after the air intake of your Fiat 500 L, i. e. just after the air filter. It is a pipe supplied with a sensor that will analyze the air in the intake and transmit the info to the ECU of your car.
Why clean the mass air flow sensor of a Fiat 500 L?
The mass air flow sensor of your Fiat 500 L can have problems and this is what we will try to find out and understand what problems you may be facing!
Mass air flow sensor problems Fiat 500 L
Here are the different problems that the air flow sensor of your Fiat 500 L can trigger:

How do I clean the mass air flow sensor from a Fiat 500 L?
After going over the operation and problems that the flowmeter can trigger, we will look at how to fix these problems by showing to you how to clean the mass air flow sensor of your Fiat 500 L . You should know that this operation is quite very easy to accomplish and you will not need advanced mechanical expertise to do it yourself, a good technique to avoid a trip to the workshop and a steep bill. See down below the different steps to stick to to accomplish this maintenance act:
- After having found the mass air flow sensor of your Fiat 500 L , you will have to dismantle it. To achieve this, 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 taken apart, you will be able to carry on to the step cleaning the mass air flow sensor of your Fiat 500 L . 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 be able to collect data properly, it is in this sense that it will disrupt the operation of the engine unit of your Fiat 500 L. The goal of this cleaning will be to remove all its impurities 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 move on to the very gentle cleaning of the flow meter filaments. You have to be very careful, in any other case 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 Fiat 500 L , you should feel a noticeable difference in the behavior of your engine unit.
