This video shows how to diagnose the MAF yourself. It explains the causes of MAF malfunction associated with its contamination, including the source of primary contamination of the sensor with silicone - inevitable with the manufacturing technology used. Several methods for cleaning the MAF are given depending on the degree of its contamination: simply cleaning with cleaning sprays; or disassembling the MAF, inspecting the condition of the sensor itself and cleaning the sensor itself. The key point of the video is how to properly disassemble the MAF to gain access to the sensor and then quickly and easily assemble it. It is noteworthy that the author of this video himself did not welcome disassembling and cleaning the sensor itself, but when he did this, then diagnosed and tested the sensor cleaned in this way, he decided to put his old 8-year-old MAF in place and put the new one he bought in reserve. As one proverb says: "it's one thing to say, and quite another to do." Watch until the end, the most interesting part is at the end!
