Malfunctioning EGR Valve Assembly
When this fault code is active, it is going to be a mechanical malfunction of the EGR valve. The valve can get a build up of carbon preventing the valve from closing fully. The EGR valve can be cleaned by qualified mechanics by removing it and cleaning the valve spool with a nylon brush and carburetor cleaner. If the mechanic is not qualified they will need to contact their local Cummins dealer to provide the proper service of the EGR Valve.
