More and more motorists are trying to take care of their cars by themselves. This outcomes in significant savings because contemporary cars necessitate more and more maintenance 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 Alfa Romeo 156 owners is a clogged air flow meter, which will lead to a loss of power and black exhaust gases. In this article we are going to look at how to clean the mass air flow sensor of your Alfa Romeo 156? . First, we will show you how your mass airflow sensor operates and its usefulness, second, why it might be relevant to clean this sensor , and finally, how to clean the mass air flow sensor of a Alfa Romeo 156 .
Utility and action of the mass air flow meter of a Alfa Romeo 156
.
So we begin our content with the operation and aim of your Alfa Romeo 156 flowmeter.
The intent of the mass air flow sensor on Alfa Romeo 156
The mass air flow sensor is a part that has been developed actually quite not long ago and principally equipped 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 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 Alfa Romeo 156, do not think twice to consult our content on this subject.
Mass air flow sensor operation on Alfa Romeo 156
Now, we are going to look at how it operates, before trying to clean the mass air flow sensor of your Alfa Romeo 156 , you must already find out how it works to achieve this maintenance work accurately.
The mass air flow sensor is consequently principally there to get statistics on the air intake of your motor vehicle. To do this, it must be installed just after the air intake of your Alfa Romeo 156, i. e. just after the air filter. It is a pipe equipped with a sensor that will review the air in the intake and transmit the statistics to the ECU of your car.
Why clean the mass air flow sensor of a Alfa Romeo 156?
The mass air flow sensor of your Alfa Romeo 156 can have complications and this is what we will try to discover and understand what complications you might be struggling with!
Mass air flow sensor complications Alfa Romeo 156
Here are the different complications that the air flow sensor of your Alfa Romeo 156 can generate:
- higher fuel consumption: Because a dirty flow meter will actually lead to excessive fuel consumption due to poor air flow…
- Power loss: Linked to similar issue, this lack of air can generate a loss of power to your engine.
- Difficulties starting the vehicle: Finally, one of the last classic complications connected to a dirty flowmeter will be that your Alfa Romeo 156 will have more issues to begin the car.
How do I clean the mass air flow sensor from a Alfa Romeo 156?
After reviewing the operation and problems that the flowmeter can generate, we will look at how to resolve these complications by describing to you how to clean the mass air flow sensor of your Alfa Romeo 156 . You should know that this operation is actually quite very easy to conduct and you will not need advanced mechanical expertise to do it your self, a good technique to avoid a trip to the mechanic and a steep bill. Discover below the different steps to follow to conduct this maintenance act:
- After having found the mass air flow sensor of your Alfa Romeo 156 , you will have to dismantle it. To do this, work gently, but you will just have to disassemble it on both sides of the air duct and disconnect the electrical plug on top of it.
- Once disassembled, you will be able to continue to the step cleaning the mass air flow sensor of your Alfa Romeo 156 . 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 accurately, it is in this sense that it will disturb the operation of the engine of your Alfa Romeo 156. The intent 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 careful, 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 Alfa Romeo 156 , you should feel a noticeable difference in the behavior of your engine.
