Alfa TS - Mass air flow (throttle closed) ?

Post by enkei » 06 Jun 2019, 19:47

I would be grateful if anyone can clarify which parts/sensors these values come from on a 2006 (CF3) Alfa 2.0 TS 147?

1. "Mass air flow (throttle closed)"

2. "Air quantity"

The reason I ask is that I suspect my MAF sensor is failing. At engine revs from idle up to 3100 rpm, "Mass air flow (throttle closed)" ranges from only 3.5-3.7 kg/h. I'm wondering if those are normal values or if they do indeed indicate a failing MAF sensor.

Also, what is "air quantity"?

Thanks in advance!
