Utility and operation of the mass air flow meter of a GMC Savana

.
So we start our article with the process and point of your GMC Savana flowmeter.

The intent of the mass air flow sensor on GMC Savana

The mass air flow sensor is a component that has been developed quite not long ago and specifically outfitted 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 injected 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 GMC Savana, do not hesitate to seek advice from our article on this subject.

  • Let soak the lower section 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 gentle cleaning of the flow meter filaments. You have to be very careful, otherwise 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 harming it, you can as well clean them with a brake fluid in the form of an aerosol by spraying the jet on these filaments.
