2010 Dodge Ram 2500 6.7 w/ Code P2271
I was looking around & it's saying if you have an aftermarket air intake system, it will trigger the code?? I have a Ram Air Intake System installed on it, truck runs fine w/ the check engine light on. Was wondering if anyone has had this problem before & what were the cause(s) for this code.

P2271 O2 Sensor Stuck Rich

During deceleration the O2 sensor should go from rick to lean in a certain amount of time and remianing rich even during deleration.

That's the best I can give...
