More and more drivers are trying to maintain their vehicles on their own. This outcomes in significant savings because contemporary cars necessitate more and more routine service and are made up of more and more technical parts that result in new breakdowns or inconveniences. One of the complications that affects more and more Tesla Model S owners is a clogged air flow meter, which will result in a loss of power and black exhaust fumes. Today we are going to examine how to clean the mass air flow sensor of your Tesla Model S? . First, we will describe how your mass airflow sensor works and its advantages, second, why it may be important to clean this sensor , and finally, how to clean the mass air flow sensor of a Tesla Model S .

Utility and operation of the mass air flow meter of a Tesla Model S

.
So we begin our article with the process and role of your Tesla Model S flowmeter.

The intent of the mass air flow sensor on Tesla Model S

The mass air flow sensor is a part that has been developed actually quite not too long ago and mainly supplied 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 injected 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 Tesla Model S, do not think twice to consult our article on this subject.

Mass air flow sensor operation on Tesla Model S

Now, we are going to look at how it works, before trying to clean the mass air flow sensor of your Tesla Model S , you must already find out how it works to achieve this routine service act correctly.

The mass air flow sensor is consequently mainly there to get info on the air intake of your car. To do this, it must be set up just after the air intake of your Tesla Model S, i. e. just after the air filter. It is a pipe supplied with a sensor that will review the air in the intake and transfer the info to the ECU of your car.

Why clean the mass air flow sensor of a Tesla Model S?

The mass air flow sensor of your Tesla Model S can have complications and this is what we will try to see and understand what complications you may be facing!

Mass air flow sensor complications Tesla Model S

Here are the different complications that the air flow sensor of your Tesla Model S can generate:

  • higher fuel consumption: Because a dirty flow meter will necessarily result in higher fuel consumption caused by poor air flow…
  • Power loss: Associated with 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 complications linked to a dirty flowmeter will be that your Tesla Model S will have more difficulties to begin the vehicle.

How do I clean the mass air flow sensor from a Tesla Model S?

After examining the operation and problems that the flowmeter can generate, we will look at how to solve these complications by explaining to you how to clean the mass air flow sensor of your Tesla Model S . You should know that this process is actually quite very easy to perform and you will not need advanced mechanical skills to do it your self, a good way to avoid a trip to the mechanic and a steep bill. See below the different steps to follow to perform this routine service act:

  • After having located the mass air flow sensor of your Tesla Model S , you will have to dismantle it. To do this, act delicately, 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 taken apart, you will be able to proceed to the step cleaning the mass air flow sensor of your Tesla Model S . 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 be able to collect data correctly, it is in this sense that it will affect the operation of the engine unit of your Tesla Model S. The intent of this cleaning will be to take out all its harmful particles 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 move on to the very delicate cleaning of the flow meter filaments. You have to be very watchful, otherwise your mass air flow sensor will be permanently broken. 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 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 Tesla Model S , you should feel a noticeable difference in the behavior of your engine unit.
