1.5L REVOTORQ ENGINE 196 STAND ALONE DIAGNOSIS / SENSOR CHECKING PROCEDURE OPERATING SPECIFICATION Equipment : Use Multimeter Power Supply : 6-16V Checking : With Ignition 'ON', Condition : Voltage between GND and Vout Signal Voltage : 4.7V (When the Flag is not in front of the sensor) : 0.6V (When the Flag is in front of the sensor) Operating Temperature: -30 0 to 120 0 C Air Gap: 0.5-1.5 mm Target Speed: 0-4000 rpm CONNECTOR DETAILS PINOUT DETAILS Pin No Description 1 Ground 2 Vout 3 Vs 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 turbocharger control. While assembling, the AMF sensor the point of the arrow should be towards the Turbo charger. SENSOR LOCATION Checking Condition  With Ignition 'ON',  Check Output Voltage between Pin 3 (MAF) and Pin 5 (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.
