Hyundai Ioniq (AE): Injector / Schematic diagrams

Circuit Diagram

    Signal WaveformThe three waveforms below are taken from the #1 and #4 injectors. The top waveform is from the high side (feed side) of the #1 and #4 injectors, while the middle waveform is from the low side (ground side) of the #1 injector and the bottom waveform is from the low side of the #4 injector.

    Inspection1.Turn the ignition switch OFF.2.Disconnect the injector connector.3.Measure resistance between the injector terminals 1 and 2.4.Check that the resistance is within the specification.
