'Ol Skewl Forum Content: What causes MAF's to fail?
Seems like this MAF thing has recently exploded into a full blown Diverter sized dilemna in the last 2-3 months. Previous to that, no one had posted any info relating to the aforementioned - MAF.
-What cause these things to fail?
-Can the warranty voiding 'chip' be a factor in the failure?
-Will preventive maintenance ie., cleaning etc. help to prevent failure?
Discuss! If you don't have authoritative and ETKA based answers, at least post some **** or something of equal interest, please!

Im on my 5th MAF which is probably dying..I have posted numerous times
on crap mafs. The problem is that they are very fragile and generally dont seem to have a long life expectancy. I dont think that theres a Hitachi Maf available yet, but I would rather have one than the junk from Bosch... plus they are very expensive and Im not looking forward to changing them periodically once my warranty is up...

I think that the M.A.F sensors in our cars are poor quality components...........
and as time goes on we will see more and more of these fail on our cars. Just take a look at the VW Vortex forum and see what I mean. They are much the same component made by the same people that gave us that great little plastic Diverter Valve. Usually a M.A.F sensor lasts the life of the engine. This is the norm. with most Jap. cars that use this kind sensor.
As far as maintenance goes, some have tried to clean a faulty M.A.F.sensor element with CO Contact Cleaner without much luck.
However, if the problem is a dirty or corroded connector (rather than the sensor element itself) then cleaning the contacts and plug helps but this is rarely the problem. Sometimes (but rarely) they look ok but still fail to make good contact and the sensor element is wrongly blamed and replaced.
