Thank you but that isn't what I meant. The new DPFE keeps sending a fault, but the info sheet accompanying the unit says the dealer can re-program PCM. The dealers in the area charge $235 an hour and up.
Just trying to save some bucks, The first dealer I called didn't know what I was talking about and said "That's an old truck."
Ah, I get it.
Dealer techs are quite good on cars up to 4 or 5 years old, but get out of touch on vehicles much older than that.
Recognize that when you called the dealer you were not speaking to a mechanic, or even an ex mechanic. Most dealers typically hire "sales" types as seevice advisors these days. There may well be someone in the shop who knows what to do, but getting to talk to them....impossible.
There is a good relevant thread I suggest you follow.
When replacing the position sensor on the EGR valve, does it need to be calibrated somehow? I had a DTC for EGR valve insufficient flow so, after some troubleshooting, I replaced the position sensor. Immediately after replacing the sensor I got EGR valve exissive flow! I cleared the code and...
Without voltage info it is hard to determine the source of your fault code.
I'd suggest you try the disconnect the battery for 10 min to clear the pcm.
I'd also suggest you disconnect and reconnect the sensor connector several times in case you have a poor electrical connection.
Finally, I'd check the engine for vacuum leaks. I find the Ford plastic vacuum lines get brittle with age and readily crack inside their sheath when moved much. Perhaps the vacuum line to the egr got moved too much and cracked?
I do not believe there is any reprogramming required beyond code clearing. This as I said can be done for free at OReilly's...
