so i had the 4# pulley installed and then a dynotune and a couple days of drivin' the L and i get the SES light on. i had pete (captain O.) scan it and it spit out EGR Flow Excessive.

anyone ever get this one? if so, what's the problem and how do i solve it? i had pete clear it the first time and it came back. any suggestions? thanks in advance...

 

I had this one, its nothing really to worry about. Mine I believe was caused by a cracked EGR tube I had from installing a phenolic spacer. I resealed it with jb weld and it hasn't come on. your egr valve may be sticking too. a few other people have had this code also. you can have your tuner turn it off I think.

 

i had this also. i have since removed all the egr equipment and my chip has the eqr equipment turned off. i believe my code was caused by a pinhole somewhere in the egr tube due to heating and bending to fit headers.

 

I had this code a while back and I just got a new EGR and it went away. You might want to fix it since I had a little issue with idling from the time the light came on to the time I fixed it.

Same for me - "Excessive Exhaust Gas Recirculation" was the code.

But I have some other symptoms - when I'm holding a steady speed at low rpms, the truck runs rough, and it sounds like it's gurgling through the exhaust. Like if I get to about 45 and it shifts into OD, and I hold it steady at 45 it chugs a bit. Once I get in it, it seems to clear up...

 

I made some great progress on my issue today. My EGR was ok - the real gremlin was a DPFE sensor. The part cost about $50 and was pretty easy to install. I ran it for a while tonight and didn't notice any of the symptoms I've been having.

Just FYI, in case anybody's having similar troubles...

 

I'm experiencing the same problem. Can you clue me in as to what th DPFE sensor actually is? Available at a parts store, or dealer only? Thanks.

 

DPFE, stands for "differential pressure feedback egr" it measures pressure drop across two exhaust "pressure inlets", (exhaust back pressure) this sends a voltage reading, to help control egr operation or "flow". A
common Ford problem, in fact a "fix" has been out there for a while via Ford on some models. See it ALOT on vehicles w/ headers , exhaust mods.... Hopes this helps.. Oh available at Ford dealers and some good parts stores that carry Motorcraft..

My DPFE sensor just starting throwing codes last week...

Looks like I'm up for a new one.

 

Do you have a part number for the DPFE?
Thanks
Swin

 

Standard Ignition sells the dpfe switch,, part #vp-8...... Funny thing is it is a re-boxed Ford part!!!!!!!!!! at least the one I have here in my hands is!!!!!!!!! Ford number is "scratched out"

 

When buying this at the store, what do you ask for? I asked for a DPFE, and they did not have that as a listed name. Pricing seems reasonable and should be no more than $50-$60.

 

First of all:

DO NOT BUY ANY ELECTRONIC ENGINE CONTROL PARTS FROM NON FORD SOURCES!!!!

most of the aftermarket parts are JUNK.

although, I agree in this particular case, the original parts are junk as well.

having said that:
they might call it any number of things, but it would make sense to call it an "EGR pressure sensor" or just plain EGR sensor or something along those lines.

the ford base part number for a DPFE is a 9J460 if I remember correctly.

good luck.

P.S. I cringe when I hear somebody say, "I had my EGR replaced". The EGR system consists of several parts, including the EGR valve, the DPFE sensor, the EVR solenoid, the PCM, and numerous metal tubes, plastic vacuum lines, and high temp rubber hoses, and electrical wiring. any ONE of these parts could cause an EGR code, and there are several EGR codes to choose from. there is a proper diagnostic procedure, but if you just throw enough parts at the problem, you'll likely get the right one sooner or later.
<rant off>

sorry.

 

Welp, mine threw:

"P1406 Differential Pressure Feedback Sensor Hose Off or Unplugged".

this is the "downstream" side hose to the EGR vacuum sensor and looking it up, it is a line that is partially solid from and a short hose that plugs into the DPE.

That only leaves three pieces that may have broken, the solid line, the short hose or the DPE.

Visually, the hoses look fine, but I have not taken it off yet.

your DPFE has two high temp rubber hoses going to it, are you sure that BOTH of these are secured on each end (to the sensor on the top end of the hose, and to the egr tube on the bottom end)?

in my experience, this code's definition has been accurate, usually just a hose that fell off or got knocked loose.

good luck.
