More and more motorists are trying to take care of their cars on their own. This results in substantial cost 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 disturbs more and more Ford S-max owners is a clogged air flow meter, which will lead to a loss of power and black exhaust fumes. Today we are going to examine how to clean the mass air flow sensor of your Ford S-max? . First, we will show you how your mass airflow sensor operates and its value, second, why it may be important to clean this sensor , and finally, how to clean the mass air flow sensor of a Ford S-max .
Utility and action of the mass air flow meter of a Ford S-max
.
So we start our article with the operation and point of your Ford S-max flowmeter.
The purpose of the mass air flow sensor on Ford S-max
The mass air flow sensor is a component that has been created actually quite not too long ago 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 Ford S-max, do not hesitate to consult our article on this subject.
Mass air flow sensor operation on Ford S-max
Now, we are going to examine how it operates, before trying to clean the mass air flow sensor of your Ford S-max , you must already figure out how it works to do this maintenance work accurately.
The mass air flow sensor is therefore mainly there to obtain statistics on the air intake of your motor vehicle. To do this, it must be installed just after the air intake of your Ford S-max, i. e. just after the air filter. It is a pipe outfitted 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 Ford S-max?
The mass air flow sensor of your Ford S-max can have problems and this is what we will try to see and understand what problems you may be facing!
Mass air flow sensor problems Ford S-max
Here are the different problems that the air flow sensor of your Ford S-max can trigger:
- higher fuel consumption: Because a dirty flow meter will necessarily bring about more significant fuel consumption because of poor air flow…
- Power loss: Associated with the same problem, this lack of air can trigger a loss of power to your engine.
- Difficulties starting the automobile: Finally, one of the last classic problems connected to a dirty flowmeter will be that your Ford S-max will have more troubles to start the vehicle.
How do I clean the mass air flow sensor from a Ford S-max?
After looking at the operation and problems that the flowmeter can trigger, we will look at how to solve these problems by showing to you how to clean the mass air flow sensor of your Ford S-max . You should know that this procedure is actually quite very easy to conduct and you will not need advanced mechanical abilities to do it yourself, a good technique to avoid a trip to the mechanic and a steep bill. Discover down below the different steps to follow to conduct this maintenance act:
- After having found the mass air flow sensor of your Ford S-max , 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 proceed to the step cleaning the mass air flow sensor of your Ford S-max . 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 affect the operation of the engine unit of your Ford S-max. The purpose of this cleaning will be to remove all its impurities to enable 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 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 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 Ford S-max , you should feel a noticeable difference in the behavior of your engine unit.
