A buddy just called me and said they had a new 6.4L come in with this code and no power. When the pulled the code, it came back as EGR Position Sensor Min/Max Stop Performance. Can anybody give me some more information on this, and what the cause is? I as well as him are new to the 6.4L so go easy on me.

this code is set when the voltage of the egr valve postion sensor is greater than the bottom limit threshold.
the egr valve has carbon buildup on it causing it to stick open and or closed.
he needs a new egr valve and chances are a new elbo, every egr valve i have tried to get out is stuck so bad you cant pull it out so changing the housing elbo is the only option.
8C3Z-9D475-D = EGR VALVE
8C3Z-9E461-A =EGR HOUSING.
