More and more drivers are trying to maintain their vehicles by themselves. This outcomes in substantial cost savings because modern cars involve more and more routine service and are done up of more and more technical components that result in new breakdowns or inconveniences. One of the problems that disturbs more and more Citroen Xsara owners is a clogged air flow meter, which will lead to a loss of power and black exhaust gases. Today we are going to examine how to clean the mass air flow sensor of your Citroen Xsara? . First, we will describe how your mass airflow sensor functions and its advantages, second, why it might be important to clean this sensor , and finally, how to clean the mass air flow sensor of a Citroen Xsara .
Utility and operation of the mass air flow meter of a Citroen Xsara
.
So we start our content with the procedure and role of your Citroen Xsara flowmeter.
The purpose of the mass air flow sensor on Citroen Xsara
The mass air flow sensor is a component that has been developed quite lately and specifically equipped on diesel models. Obviously, with injection engines, the fuel and air intake has become very precise and it is consequently important for the ECU to know the exact volume of air injected 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 Citroen Xsara, do not hesitate to consult our content on this subject.
Mass air flow sensor operation on Citroen Xsara
Now, we are going to have a look at how it functions, before trying to clean the mass air flow sensor of your Citroen Xsara , you must already figure out how it functions to achieve this routine service act correctly.

The purpose of this cleaning will be to remove all its harmful particles to enable it to work efficiently again.
- 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 gentle cleaning of the flow meter filaments. You have to be very watchful, in any other case 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 destroying it, you can as well clean them with a brake fluid in the form of an aerosol by spraying the jet on these filaments.
