MAF sensor diagnose
Hello !
i noticed it
S-Max 2.0 TDCi 110kw
Ignition key the ON position, engine not running and MAF sensor shows 2,11 g/s
this is normal ?

Re: MAF sensor diagnose
That is not normal. It should read 0 when the engine is not running.
I don't know the exact figures for your engine, but at tick over I would expect it to be somewhere around 6 or 7 and be steady, and rise to high double figures under extreme load.
Hopefully someone with the same engine as you can confirm the normal expected values.

These are the readings from a MAZDA 3 2L Petrol 2010
Ignition on Engine NOT running
And
Engine running ... Idling at about 750RPM
Try to clean your MAF Sensor with Sensor Cleaner first ...

Re: MAF sensor diagnose
Thanks !
when the engine running 800rpm and maf 12g/s
i can't find the Forscan MAF sensor volt PID-s only MAF g/s and MAF hz
car mileage is 25000km

Re: MAF sensor diagnose
Quick question
Can forscan via pc read the voltage from a MAF sensor ?

Re: MAF sensor diagnose
Yes !!
Re: MAF sensor diagnose
So I have stalling and hesitation at idle for my 2011 mustang.
On forscan it shows g/s is around 5 and but the volts are at a constant “0”. What does that mean ? (Idle )
