information values mass air flow sensor and the turbine

[mjet10]

Hello, yesterday I got the curiosita'to check the mass air flow sensor,and misono noticed that indiagnosi to a minimum the car if the quantity of air required was 150 mg that read was 350 mg and then higher, but when aceleravo to fund the amount required was 1000 mg, and the read is around 500 mg.
This behavior normal? I have to test it in gear? Percbe' I tried to be firm. However, the car is great Info point 90 hp mjet

Hello These values from a standstill are normal, to make a test, I suggest you to do it while driving.. simply by selecting the target and measured..

ok, later I try, but in march when it should be the value at full load?

Have you tried to measure with the oscilloscope the voltage value, that you d? accelerating from a standstill.
Not ? as a rule, but if it exceeds 3.5 V you can be sure that it works.

[mjet10]

No I have not tried,but which wires I have to try

or a simple multimeter.

It must be measured between pin 5 and ground (pin 3).

Ok, perfect realized later I try and I want to know

returning home I tried it with diadnosi attacked and The real values at full load are between 900 and 800 I think they are ok.poi I would like to ask if you can also a few other technical information on my car, but I am afraid to go outside of the ot can I ask the question I will open another post?

lately, I have tried it on panda, 70 hp and grande punto 75 hp at full load between 580-600 mg while on the grande punto 90 hp 900 mg.......

are 2 debimetri different!!!

I also checked the voltage and it is ok:-) so,anyway, my question ori this car as it spins the turbine?

I changed the title of the discussion, so as not to go off topic
