🚗 How to Diagnose GDI Injectors Using Waveform Analysis | Fuel Pressure Drop Test Explained
In this video, I’ll walk you through a professional method to diagnose faulty GDI (Gasoline Direct Injection) fuel injectors using fuel rail pressure sensor waveforms. You’ll see how to capture and analyze pressure drops at each injector event to accurately identify a weak or defective injector.
📊 I use oscilloscope waveform analysis to interpret the fuel pressure signatures, allowing for non-intrusive injector diagnostics without removing components. This technique works great for modern GDI systems and can save hours in troubleshooting time.
🔧 Perfect for automotive technicians, diagnostics professionals, and advanced DIYers wanting to up their game in GDI injector testing.
✅ What You'll Learn in This Video:
How to connect to the fuel rail pressure sensor
Interpreting waveform patterns for each injector
Identifying a weak or stuck GDI injector
Tips for using pressure transducers or scope setups
📹 Tools Used:
Automotive oscilloscope with 2 Channels.
