I have a 2001 mustang v6 tested and a code P0401 came up, but in the repair manual there is a OBD-1 TROUBLE CODES AND A OBD-2 trouble code page the code P0401 is listed under the OBD-2 is a 3.8L a V6? can the EGR solenoid cause this code also? I hope I'm making sense.
Was told that the EGR its self was fine. All info is appreciated.
