More and more drivers are trying to maintain their cars on their own. This results in substantial cost savings because contemporary cars involve more and more maintenance and are done up of more and more technical components that lead to new breakdowns or inconveniences. One of the complications that affects more and more Land Rover LR4 owners is a clogged air flow meter, which will bring about a loss of power and black exhaust gases. In this article we are going to take a look at how to clean the mass air flow sensor of your Land Rover LR4? . First, we will describe how your mass airflow sensor works and its advantages, second, why it might be important to clean this sensor , and finally, how to clean the mass air flow sensor of a Land Rover LR4 .
Utility and operation of the mass air flow meter of a Land Rover LR4
.
So we start our article with the procedure and purpose of your Land Rover LR4 flowmeter.
The goal of the mass air flow sensor on Land Rover LR4
The mass air flow sensor is a component that has been developed quite not too long ago and specifically equipped on diesel models. In truth, with injection engines, the fuel and air intake has become very precise and it is therefore important 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 Land Rover LR4, do not think twice to consult our article on this subject.
Mass air flow sensor operation on Land Rover LR4
Now, we are going to have a look at how it works, before trying to clean the mass air flow sensor of your Land Rover LR4 , you must already find out how it functions to achieve this maintenance action accurately.
The mass air flow sensor is consequently specifically there to get statistics on the air intake of your motor vehicle. To get this done, it must be mounted just after the air intake of your Land Rover LR4, i. e. just after the air filter. It is a pipe equipped with a sensor that will review the air in the intake and transfer the statistics to the ECU of your car.
Why clean the mass air flow sensor of a Land Rover LR4?
The mass air flow sensor of your Land Rover LR4 can have complications and this is what we will try to find out and discover what complications you might be struggling with!
Mass air flow sensor complications Land Rover LR4
Here are the different complications that the air flow sensor of your Land Rover LR4 can provoke:
- higher fuel consumption: Because a dirty flow meter will necessarily bring about more significant fuel consumption caused by poor air flow…
- Power loss: Linked to similar problem, this lack of air can provoke a loss of power to your engine.
- Difficulties starting the car: Finally, one of the last classic complications associated with a dirty flowmeter will be that your Land Rover LR4 will have more issues to start the car.
How do I clean the mass air flow sensor from a Land Rover LR4?
After looking at the operation and complications that the flowmeter can provoke, we will look at how to resolve these complications by explaining to you how to clean the mass air flow sensor of your Land Rover LR4 . You should know that this procedure is quite simple to conduct and you will not need advanced mechanical expertise to do it your self, a good way to avoid a trip to the garage and a steep bill. Discover below the different steps to stick to to conduct this maintenance act:
- After having based the mass air flow sensor of your Land Rover LR4 , you will have to dismantle it. To get this done, action 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 taken apart, you will be able to carry on to the step cleaning the mass air flow sensor of your Land Rover LR4 . 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 accurately, it is in this sense that it will affect the operation of the engine of your Land Rover LR4. The goal of this cleaning will be to take out all its impure substances 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 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 Land Rover LR4 , you should feel a noticeable difference in the behavior of your engine.
