Technical Diesel MAF Sensor

[Piotr129]

"I have a 2018 Fiat Ducato 2.3 MultiJet (150 HP). What should be the MAF (Mass Air Flow) sensor value when both EGR valves are closed? This state can be achieved by leaving the engine idling for a few minutes without touching the accelerator pedal. I’ve observed a value of 720 mg/i (mg/stroke) in my van. In my opinion, this seems a bit too high."

From basic calcs:
2.287 cm3 @ 750rpm @ 25ºC @ sea level @ 95% VE = 636 mg/i

Not very different.

Thank you for the answer. I know many people here use MultiEcuScan (MES). If anyone has some spare time and could check this in their van, I would be very grateful.

Has anyone here used the 'reset self-learned parameters' function in MultiEcuscan and can share their experience?
