Thumbs down 2004 2.3L EGR/DPFE blues.

Hi! I always search the forum for help and it's been great so far, except with my current problem so I decided to sign up and post it. Hopefully someone will know.

Truck: 2004 2.3L Ranger

I have a CEL (p0401) and I had the EGR valve replaced thanks to this forum. It is unusual looking (more of a cylinder than the traditional saucer) on the back of the engine by the firewall and the transmission had to be lowered to get to it. This turned my light off for a day or so and then the problems returned along with the light. so HOPEFULLY someone out there can enlighten me.

Where is the DPFE sensor on my 2004 2.3L? and how do I change it?

Were you able to figure out if you EGR passages were plugged when you changed the EGR?? Mine was pretty nasty.

Not 100% sure where the dpfe is on your '04 but this is what it looks like -

I believe the EGR is under the arch of the intake. It plugs into the DPFE. I haven't torn my truck down quite that far yet. It's a project for vacation in about 4 weeks.

I plan on taking a lot of pics when I jump on this and I'll put them on here.
