2005 Dodge Dakota 4.7L V8 P0175 Running Rich - No Live Codes, What Does This Mean?
I'm experiencing a running rich condition with my 2005 Dodge Dakota equipped with a 4.7L V8 engine. The check engine light is on, and the vehicle shows a stored diagnostic trouble code (DTC) P0175, which indicates a lean condition in bank 2 sensor 1 — however, I'm not seeing any live or real-time codes when using a Snap-on scan tool. I've already replaced the ignition coils, spark plugs, and fuel injectors. I also ran Sea Foam through the system to clear potential injector clogs, but the issue persists. Since I'm a U.T.I student with access to tools, I'm looking for expert advice on how to diagnose and fix this P0175-related running rich problem. Any insights into possible causes or next steps would be greatly appreciated.
You mentioned no live codes but a stored P0175 — isn't that a diagnostic code? Please verify if your scan tool is showing any real-time fuel trims or sensor readings, especially for Bank 2 Sensor 1 voltage and fuel trim values. These data points are critical in diagnosing a running rich condition with P0175.
