Hi all,

For me the MAF sensor has allways been a sensor that is hard to diagnose. Most of the times I am using my scantools and oscilloscoop to check the signal of the MAF sensor. If I am lucky there is some specified value info in the workshop manuals.

Now I using an app called MAF-Calc on my smartphone for a while. I must say I like it. The app calculates the theoretical MAF value and I can compare the calculated value with the value shown on the scantool.

There is a Apple and Android version of this app.
