Fig. 16: Single Injector w/Excessive Current Flow - Current Pattern
EXAMPLE #8 - CURRENT CONTROLLED DRIVER This known-good CPI system waveform from a GM 4.3L V6 CPI VIN [W] peaks at 4 amps and holds at 1-amp. See Fig. 17 for waveform.
Fig. 17: Single Injector w/Normal Current Flow - Current Pattern
VOLTAGE WAVEFORM SAMPLES EXAMPLE #1 - VOLTAGE CONTROLLED DRIVER These two known-good waveform patterns are from a Ford 4.6L V8 VIN [W]. Fig. Fig. 18 illustrates the 64 volt inductive kick on this engine, indicating no clamping is occurring. The second pattern, Fig. Fig. 19 , was taken during hot idle, closed loop, and no load.
