How to clean the mass air flow sensor on a Peugeot

Model: Peugeot Peugeot Various
Part: MAF sensor

Video tutorial

In this video we can see how to clean the Mass Air Flow (MAF) sensor on a Peugeot car: its function is to measure the amount of air taken in by the engine. It is located on the air filter box, and we will need to remove the electrical connector of the sensor.

On some cars, it is further secured by two sealing screws; loosen the clips of the clamp and completely remove the sensor, which can be easily cleaned with a specific cleaner for the MAF sensor; we will focus the cleaner flow on the highlighted pin in the video.

Be careful not to touch it with your hands! Then let it dry well in the air before putting it back in place.
