Don't mean to butt in but it's ALWAYS ALWAYS ALWAYS the DPFE sensor. Remove it and take the 2 hoses off. Tap it on a dry surface where the 2 hoses attach. If ANY MOISTURE whatsoever comes out, replace it. Replace the two hoses if you can find them. I replace them ALL THE TIME on Fords.

Dave you were right on about the DPFEGR sensor. I replaced it and cleared the MIL code. After driving all day the light never came back on. Rescaned the engine and the system monitors checked off the EGR. I would recommend this site to anyone. Saved me a lot of money. Thanks. Hello Jasonray. You can jump in anythime with good advice.
