Utility and action of the mass air flow meter of a Bmw Serie 2

.
So we start our content with the procedure and intent of your Bmw Serie 2 flowmeter.

The goal of the mass air flow sensor on Bmw Serie 2

The mass air flow sensor is a part that has been created actually quite lately and principally outfitted on diesel models. In truth, with injection engines, the fuel and air intake has become very precise and it is so necessary 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 Bmw Serie 2, do not hesitate to seek advice from our content on this subject.

Mass air flow sensor operation on Bmw Serie 2

Now, we are going to take a look at how it functions, before trying to clean the mass air flow sensor of your Bmw Serie 2 , you must already understand how it works to do this routine service action accurately.
