GDI Injector Circuit Malfunction - Cylinder Specific
2007-2011 Dodge Nitro 3.7L V6
Description
A GDI fuel injector has an electrical circuit fault. GDI injectors require high-voltage driver circuits for precise fuel delivery at extremely high pressures.
Symptoms
- Check Engine Light
- Misfire on affected cylinder
- Rough idle
- Loss of power
- Exhaust smell
- Catalyst damage risk
Common Causes
- Injector coil failure
- Injector driver circuit fault in PCM
- Wiring damage to injector
- Connector pin corrosion
- Injector stuck open or closed
Diagnostic Steps
- Identify affected cylinder from freeze frame
- Test injector resistance
- Check injector driver waveform with oscilloscope
- Inspect injector connector
- Swap injectors between cylinders to confirm
Repair Notes
Replace faulty GDI injector. Use OEM injectors - aftermarket injectors may not meet flow and spray specifications. Perform injector coding if required.
