More and more drivers are trying to maintain their cars on their own. This results in considerable cost savings because modern cars necessitate more and more routine service and are done up of more and more technical parts that lead to new breakdowns or inconveniences. One of the problems that impacts more and more Volkswagen Jetta owners is a clogged air flow meter, which will end in 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 Volkswagen Jetta? . First, we will describe how your mass airflow sensor operates and its advantages, second, why it might be relevant to clean this sensor , and finally, how to clean the mass air flow sensor of a Volkswagen Jetta .
Utility and action of the mass air flow meter of a Volkswagen Jetta
.
So we begin our article with the operation and aim of your Volkswagen Jetta flowmeter.
The purpose of the mass air flow sensor on Volkswagen Jetta
The mass air flow sensor is a component that has been created 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 necessary 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 Volkswagen Jetta, do not think twice to consult our article on this subject.
Mass air flow sensor operation on Volkswagen Jetta
Now, we are going to have a look at how it operates, before trying to clean the mass air flow sensor of your Volkswagen Jetta , you must already find out how it functions to do this routine service act correctly.
The mass air flow sensor is consequently principally there to get statistics on the air intake of your car. To achieve this, it must be installed just after the air intake of your Volkswagen Jetta, i. e. just after the air filter. It is a pipe supplied 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 Volkswagen Jetta?
The mass air flow sensor of your Volkswagen Jetta can have problems and this is what we will try to find out and figure out what problems you might be facing!
Mass air flow sensor problems Volkswagen Jetta
Here are the different problems that the air flow sensor of your Volkswagen Jetta can trigger:
- higher fuel consumption: Because a dirty flow meter will necessarily end up in higher fuel consumption because of poor air flow…
- Power loss: Related to the same problem, this lack of air can trigger a loss of power to your engine.
- Difficulties starting the car: Finally, one of the last traditional problems linked to a dirty flowmeter will be that your Volkswagen Jetta will have more difficulties to begin the car.
How do I clean the mass air flow sensor from a Volkswagen Jetta?
After looking at the operation and problems that the flowmeter can trigger, we will look at how to resolve these problems by describing to you how to clean the mass air flow sensor of your Volkswagen Jetta . You should know that this procedure is quite very easy to carry out and you will not need advanced mechanical abilities to do it your self, a good way to avoid a trip to the workshop and a steep bill. Discover down below the different steps to stick to to carry out this routine service act:
- After having located the mass air flow sensor of your Volkswagen Jetta , you will have to dismantle it. To achieve this, act 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 have the ability to carry on to the step cleaning the mass air flow sensor of your Volkswagen Jetta . 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 correctly, it is in this sense that it will affect the operation of the engine of your Volkswagen Jetta. The purpose of this cleaning will be to remove all its impure substances to enable 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 move on to the very delicate cleaning of the flow meter filaments. You have to be very careful, 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 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 Volkswagen Jetta , you should feel a noticeable difference in the behavior of your engine.
