More and more motorists are trying to take care of their cars on their own. This results in considerable cost savings because modern cars require more and more maintenance and are made up of more and more technical components that lead to new breakdowns or inconveniences. One of the problems that affects more and more Subaru Impreza owners is a clogged air flow meter, which will bring about 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 Subaru Impreza? . First, we will describe how your mass airflow sensor functions and its advantages, second, why it might be relevant to clean this sensor , and at last, how to clean the mass air flow sensor of a Subaru Impreza .
Utility and action of the mass air flow meter of a Subaru Impreza
.
So we begin our content with the operation and intent of your Subaru Impreza flowmeter.
The purpose of the mass air flow sensor on Subaru Impreza
The mass air flow sensor is a part that has been developed actually quite recently and specifically outfitted 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 loaded into the engine to adapt the actions of complementary intake parts such as the injection or the EGR valve, if you have problems with the EGR valve on your Subaru Impreza, do not think twice to consult our content on this subject.
Mass air flow sensor operation on Subaru Impreza
Now, we are going to look at how it functions, before trying to clean the mass air flow sensor of your Subaru Impreza , you must already understand how it works to achieve this maintenance act properly.
The mass air flow sensor is therefore specifically there to obtain data on the air intake of your car. To do this, it must be mounted just after the air intake of your Subaru Impreza, i. e. just after the air filter. It is a pipe outfitted with a sensor that will analyze the air in the intake and transfer the data to the ECU of your car.
Why clean the mass air flow sensor of a Subaru Impreza?
The mass air flow sensor of your Subaru Impreza can have problems and this is what we will try to discover and understand what problems you might be struggling with!
Mass air flow sensor problems Subaru Impreza
Here are the different problems that the air flow sensor of your Subaru Impreza can generate:
- higher fuel consumption: Because a dirty flow meter will necessarily end in higher fuel consumption because of poor air flow…
- Power loss: Linked to similar problem, this lack of air can generate a loss of power to your engine.
- Difficulties starting the vehicle: Finally, one of the last classic problems connected to a dirty flowmeter will be that your Subaru Impreza will have more issues to begin the car.
How do I clean the mass air flow sensor from a Subaru Impreza?
After reviewing the operation and concerns that the flowmeter can generate, we will look at how to fix these problems by showing to you how to clean the mass air flow sensor of your Subaru Impreza . You should know that this procedure is actually quite basic to perform and you will not need advanced mechanical expertise to do it your self, a good method to avoid a trip to the garage area and a steep bill. See below the different steps to stick to to perform this maintenance act:
- After having located the mass air flow sensor of your Subaru Impreza , you will have to dismantle it. To do this, act 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 proceed to the step cleaning the mass air flow sensor of your Subaru Impreza . 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 Subaru Impreza. The purpose of this cleaning will be to remove all its impure substances 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 cautious, in any other case 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 destroying 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 Subaru Impreza , you should feel a noticeable difference in the behavior of your engine unit.
