2003 Dodge 3500 Cummins P2146 Code: What It Means and How to Fix It
I own a 2003 Dodge 3500 with a 5.9L Cummins engine. After installing an Edge Hot Box, my truck briefly flashes the check engine light and displays a P2146 diagnostic trouble code. I'm looking for clarification on what this code means and how to resolve it. Any insights or troubleshooting steps would be greatly appreciated.
P2146 indicates a fault in the Fuel Injector Group A Supply Voltage Circuit or Open circuit. This could point to an issue with the wiring, connector, or the injector itself. Check for loose connections, corrosion, or damaged harnesses near the fuel injectors.
