So trying to get through emissions and having issues with P1400 (EGR Valve Circ Electrical Malfunction) and 1409 (Tank Ventilation Valve Circ. Electrical Malfunction).

Anyone have any experience with these? Found some related links online that pointed to the N80 valve. I thought there was a seperate code for that but took it off and looks clean as a whistle inside.
