iv. AIR MASS FLOW SENSOR
This sensor is mounted between air filter and
turbocharger. It gives Information about the
amount of air quantity & temperature entering the
engine.
This input is used by the ECU for corrections of
fuel quantity based on amount of air availability for
optimization of exhaust gas circulation & the
