Oscilloscope Waveform Analysis
1 ms/div, 20 V/divPossible Causes
Mechanical sticking or debris/carbon contamination jamming Fuel Injector/Injection Timing Control Circuit
Chafed or pinched wiring harness along the signal path to Fuel Injector/Injection Timing Control Circuit
Internal mechanical wear or carbon deposits inside Fuel Injector/Injection Timing Control Circuit
Defective internal output driver or reference circuit in the control module for Fuel Injector/Injection Timing Control Circuit
Symptoms
Recommended Solution
Remove component and inspect for carbon deposits or foreign debris preventing full mechanical closure.
Verify loaded supply voltage and harness terminal pins at Fuel Injector/Injection Timing Control Circuit.
Check circuit continuity and ground-side voltage drop (< 0.05 V) for Fuel Injector/Injection Timing Control Circuit.
Perform fuel rail pressure-drop / balance test to identify leaking, stuck, or clogged injectors.
Mechanic's Tip
Pair a current clamp with your voltage channel on the scope. The distinct dip in the current ramp marks the physical pintle lift — no dip means the coil is energized but the needle is mechanically seized.
