Injector Circuit CIRCUIT DESCRIPTION The injectors are located in the intake manifold. They inject fuel into the cylinders based on the signals from the engine control module. Reference INSPECTION USING OSCILLOSCOPE • With engine idling measure waveform between terminals # 10 ~ 60 and E01 of engine control module. HINT: The correct waveform is as shown.
