More and more car owners are trying to take care of their vehicles on their own. This results in substantial cost savings because contemporary cars require more and more maintenance and are made up of more and more technical components that result in new breakdowns or inconveniences. One of the problems that impacts more and more Mercury Mariner owners is a clogged air flow meter, which will end in a loss of power and black exhaust gases. Today we are going to examine how to clean the mass air flow sensor of your Mercury Mariner? . First, we will teach you how your mass airflow sensor functions and its advantages, second, why it may be relevant to clean this sensor , and at last, how to clean the mass air flow sensor of a Mercury Mariner .
Utility and action of the mass air flow meter of a Mercury Mariner
.
So we start our article with the procedure and intent of your Mercury Mariner flowmeter.
The goal of the mass air flow sensor on Mercury Mariner
The mass air flow sensor is a part that has been created quite lately and mainly outfitted on diesel models. In truth, with injection engines, the fuel and air intake has become very precise and it is therefore necessary for the ECU to know the exact volume of air loaded into the engine to change the behaviour of complementary intake parts such as the injection or the EGR valve, if you have problems with the EGR valve on your Mercury Mariner, do not think twice to consult our article on this subject.
Mass air flow sensor operation on Mercury Mariner
Now, we are going to check out how it functions, before trying to clean the mass air flow sensor of your Mercury Mariner , you must already figure out how it functions to achieve this maintenance work accurately.
The mass air flow sensor is consequently mainly there to get statistics on the air intake of your car. To achieve this, it must be fitted just after the air intake of your Mercury Mariner, i. e. just after the air filter. It is a pipe outfitted with a sensor that will analyze the air in the intake and transmit the statistics to the ECU of your car.
Why clean the mass air flow sensor of a Mercury Mariner?
The mass air flow sensor of your Mercury Mariner 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 Mercury Mariner
Here are the different problems that the air flow sensor of your Mercury Mariner can bring about:
- higher fuel consumption: Because a dirty flow meter will actually lead to excessive fuel consumption caused by poor air flow…
- Power loss: Associated with similar problem, this lack of air can bring about a loss of power to your engine.
- Difficulties starting the car: Finally, one of the last traditional problems associated with a dirty flowmeter will be that your Mercury Mariner will have more difficulties to start the vehicle.
How do I clean the mass air flow sensor from a Mercury Mariner?
After going over the operation and concerns that the flowmeter can bring about, we will look at how to fix these problems by explaining to you how to clean the mass air flow sensor of your Mercury Mariner . You should know that this procedure is quite very easy to carry out and you will not need advanced mechanical skills to do it yourself, a good way to avoid a trip to the workshop and a steep bill. See down below the different steps to follow to carry out this maintenance act:
- After having found the mass air flow sensor of your Mercury Mariner , you will have to dismantle it. To achieve this, work delicately, 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 proceed to the step cleaning the mass air flow sensor of your Mercury Mariner . This sensor will, as time passes, 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 Mercury Mariner. The goal of this cleaning will be to take out all its impurities 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 take out 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, delicately clean the two filaments of your mass air flow sensor . If you are too afraid of harming 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 Mercury Mariner , you should feel a noticeable difference in the behavior of your engine.
