More and more car owners are trying to take care of their cars 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 affects more and more Toyota Rav 4 owners is a clogged air flow meter, which will bring about a loss of power and black exhaust fumes. In this article we are going to check out how to clean the mass air flow sensor of your Toyota Rav 4? . First, we will teach you how your mass airflow sensor operates and its value, second, why it may be relevant to clean this sensor , and at last, how to clean the mass air flow sensor of a Toyota Rav 4 .
Utility and action of the mass air flow meter of a Toyota Rav 4

So we begin our content page with the procedure and goal of your Toyota Rav 4 flowmeter.
The intent of the mass air flow sensor on Toyota Rav 4
The mass air flow sensor is a part that has been developed quite not too long ago and principally supplied on diesel models. Indeed, with injection engines, the fuel and air intake has become very precise and it is so important for the ECU to know the exact volume of air added into the engine to modify the actions of complementary intake parts such as the injection or the EGR valve, if you have problems with the EGR valve on your Toyota Rav 4, do not think twice to consult our content page on this subject.
