Re: EGR codes p1404 & p0404
DTC P1404 Exhaust Gas Recirculation (EGR) Closed Position Performance
DTC P0404 Exhaust Gas Recirculation (EGR) Open Position Performance
This vehicle uses a linear egr that has the control and valve all in one unit. With these codes it's pretty common to see some small pieces of carbon stuck in the egr pintle holding it open. I'd pull the egr valve off and check for this. I won't tell you to replace it but If it was mine and I didn't find anything in it I'd replace it.
