146 ENGINE2.2LDICOR SIMAFSensor (Fig. 243) PinAssignment Pin 1 : + Ub Pin 2 : Uext Pin 3 : MAFSignal Pin 4 : IAT+ Pin 5 : GND/IATCheckingCondition l With Ingnition 'ON', l Check Output Voltage between Pin 3 (MAF) and Pin5 (GND). l 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". Fig. 243 Fig. 244 Crank AngleSensor (Fig. 244) PinAssignment Pin 1 - Positive terminal Pin 2 - Negative terminal CheckingCondition Measure resistance across the terminals using Digital multimeter. Signal Output Resistance spec : 2400 ohms ± 240@250C.
