This results in considerable savings because modern cars involve more and more maintenance and are made up of more and more technical parts that lead to new breakdowns or inconveniences. One of the problems that disturbs more and more Toyota C-hr owners is a clogged air flow meter, which will bring about a loss of power and black exhaust gases. Today we are going to look at how to clean the mass air flow sensor of your Toyota C-hr? . First, we will describe how your mass airflow sensor functions and its usefulness, second, why it might be relevant to clean this sensor , and finally, how to clean the mass air flow sensor of a Toyota C-hr .

.
So we begin our article with the procedure and purpose of your Toyota C-hr flowmeter.

The intent of the mass air flow sensor on Toyota C-hr

The mass air flow sensor is a part that has been developed actually quite recently and principally supplied on diesel models. In fact, with injection engines, the fuel and air intake has become very precise and it is therefore essential 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 C-hr, do not think twice to seek advice from our article on this subject.

  • 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 remove most of the grime
  • .

  • Now we’ll proceed 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.
