p0401, p0402 EGR DPFE

dkoenig · #1 (**permalink**) 05-17-2008, 08:34 AM

I have read the threads on the above codes as I have had these issues over the past 3/4 year. The prescribed fixes (clean TB, replace DPFE and maybe EGR) have worked. However, I am wondering what might cause me to have to replace (under warranty) the DPFE multiple times over the past 1.5 years. Is there something upstream or downstream might cause them to fail prematurely?

Thanks,

Don

After market or Ford DPFE?

If after market, that's your likely answer.

Thanks for the advice. i ended up replacing it with one from NAPA,and no more code. I have it logged when I did it, so we will see how long it lasts.

There is a thread here about repairing a OEM DPFE sensor. I'm on my 3rd AZ DPFE right now and I'm heading to a junkyard to get an OE and run it until it pulls codes then I'll fix it. Meanwhile I take it back to AZ and get a refund as it has a lifetime warranty.
Fortunately other than a slight loss of power it's not a big deal.
