CheckingCondition

With Ingnition 'ON',

Check Output Voltage between Pin 3 (MAF) and

Pin5 (GND).

Check Output Current between Pin 1 (Ub) and Pin

5(GND).

Signal/Output Current

The current consumption has to be between 35 and

55mA.

Signal/Output Voltage

The analog output signal is good between 0 and 1V

NOTE

Check theSIMAFSensor with nomass flow. The above

given values are for zero mass flow. Every tiny whiff of

air will cause a NTF".
