Mass Air Flow (Kg/H)

Measurement range 0-1020 kg/h.

The value indicates the mass air flow that passes through the mass air flow (MAF) sensor.

The engine control module (ECM) derives the value based on the signal from the mass air flow (MAF) sensor.

Normal value with the engine at operating temperature and idling, neutral and air conditioning (A/C) switched off: approximately 12-20 kg/h.

NOTE:

Other values apply if the generator is under load, e. g., high beam is on, the heated rear window is on, etc.
