Kia Sorento: Signal Waveform - Injector - Engine Control System - Engine Control / Fuel System - Kia Sorento XM 2011-2022 Service ManualKia Sorento: Signal Waveform

Second Generation XM (2011-2022) / Kia Sorento XM 2011-2022 Service Manual / Engine Control / Fuel System / Engine Control System / Injector / Signal Waveform

The 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.
The middle waveform is the same as the top waveform because there is no ground for the circuit. With no current flowing in the circuit, the #1 injector is not energized and fuel does not flow.
The bottom waveform shows that ground is supplied and there is a voltage drop across the #4 injector. With current flowing in the circuit, the #4 injector is energized and fuel flows.
