A friend of mine had a CEL on a 2002 F-150 4.6 with 65,000 miles. I pulled the code, which was the one relating to EGR flow insufficient (I don't remember the exact code, it's been a few weeks). I told her that it was most likely the DPFE sensor, and sent her to Ford to get one. When she returned with the sensor, I couldn't find a DPFE sensor on the truck for the life of me. My questions are:
1) Does this truck even have the DPFE sensor?
2) If so, WHERE?
3) If not, what other things would set that code?
I suppose the EGR ports could be clogged or theres a broken vac line somewhere. Any help is appreciated!
