Reading these posts and talking to my favorite ASE tech.
I have DTC 0401 come up and the service engine light stays on.
At his suggestion I ordered a new EGR Control Valve. Which is the solenoid on the green vacuum line. Is this the same thing folks are calling DPFEGR sensor ?.It was described as being in the same place.
Rectangular with wiring attached (as buzzard said) with two black hoses going to it from the exhaust. You did'nt say what type of engine you have, or year model, but if it is a 4.2 the egr tubes can stop up, a 4.6 has passages that can clog, right behind the throttle plate, and Ford extended the mileage for warranty on the tube mounted DPFE sensor on some vehicles.
Got it ..............I'm a little slow. It almost bit me.
On my control valve. It must have a superceded part.
I took out F57E-9J459-CA ,,,,,,,,,,,,,, I put in F63Z-9J459-AA.
Where would one find out if I got the right one ?
