More and more car owners are trying to maintain their vehicles by themselves. This outcomes in considerable savings because modern cars involve more and more maintenance and are made up of more and more technical components that lead to new breakdowns or inconveniences. One of the problems that impacts more and more Peugeot 407 owners is a clogged air flow meter, which will result in a loss of power and black exhaust gases. In this article we are going to look at how to clean the mass air flow sensor of your Peugeot 407? . First, we will show you how your mass airflow sensor works 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 Peugeot 407 .
Utility and operation of the mass air flow meter of a Peugeot 407
.
So we begin our article with the operation and role of your Peugeot 407 flowmeter.
The purpose of the mass air flow sensor on Peugeot 407
The mass air flow sensor is a part that has been developed quite lately and specifically equipped on diesel models. Indeed, 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 adapt the behaviour of complementary intake parts such as the injection or the EGR valve, if you have problems with the EGR valve on your Peugeot 407, do not think twice to seek advice from our article on this subject.
