Egr shot
Is it possible for an egr to be shot, or out of calibration. After this weekend of vgt actuator replacement and overhead, I took me egr off again and cleaned it, it wasnt that dirty and could still see shiny parts on the valve, which also felt good and moved with out any sticky spots. If it is bad they want 3 arms and legs for them. Is it possible it's not zeroed back to the closed position throwing both codes

RE: Egr shot
could be,.. also could be wiring. Have you replaced the egr pressure sensor?

RE: Egr shot
Being a voltage fault - You are looking at a wiring harness or internal EGR valve electrical failure, not a mechanical one.

Check the condition of the pins in the EGR valve connector & check continuinty from it to the ECM.

RE: Egr shot
did you fix this already? the pressure sensor code says it disables the egr.....check continuity and ohms from ecm to that harness if everthing seems fine, its the sensor.... change it and the egr code must clear.
