P0401 2005 4.6L
I have 170k miles on my 05 4.6 and just pulled the P0401 code- EGR Insufficient flow. I pulled the throttle body off and cleaned it thoroughly as well as the metal elbow and the EGR ports. I see that the DPFE sensor is built into the EGR valve, so should replacing the valve be my next concern? What do ya'll think?
