EGR code and Zero Driveability problems?
I know from time to time trucks will throw an odd code you clear it and it never comes back, keeping that in mind I was looking for some solid advice on my egr code.
Code P0401 is in my computer now and I am debating on:
The clean the egr and reinstall method ( 1- 2 hrs depending on how dirty) and hope that solves the problem (great post in the tech section very thorough but I have had little luck cleaning the egrs on gassers)
Replace with updated egr valve keep old one clean at my leisure to reinstall if (rather) when the code lights up again
Deleting the whole egr setup with the sct? and egr tube (this is my least approach just for the what if factor)
My truck is an '03 f350 with the 6.0 and overall I have had little problem with it

Hey Green my truck has had EGR Problems before twice matter of fact
1st time it threw a 401 insuffecent flow no power what so ever & surged it was a EGR Valve then
2nd time it threw a 402 Excessive flow this time didnt surge BUT NO POWER & Almost died @ the light i was sitting@ the time
that time it was a DPFE Sensor
not sure if the 6.0 HAS A DPFE Sensor ya might check your dealer or mechanic to see if it has a DPFE Sensor also that was my colpurt the last time
hope this helps

Differential Pressure Feedback EGR system. It is not installed on the 6.0 or 6.4 PSD.
It is installed on some Ford gas engine vehicles. The DPFE measures the flow throught the EGR valve and sends this info to the PCM so that the EGR valve can be better regulated by the PCM for given load and driving conditions.

sorrry foir the delay benn workin my A$$ off
Bowtie - my truck is 100% stock right now, as mucjh as I owul dlike to play with it it is my daily driver and I am looking to improve the reliability as well as pulling some more torque and HP out of it for pulling trailers without breaking the bank or the truck.
In other words I ain't rich
Seriously just looking to be cautious and do as much diagnosing and repairs my self to keep costs down, which leads to my next ??
I want to get an aftermarket scan toolfor my truck ( as well as my wifes Ch3^y) I am torn between an sct xcal setup ( that is vehicle specific right?) or say an actron type scan tool that will help me diagnose etc. I have done some reading here but still have ???
Everyone Thanks for all the info etc

reason why i asked about the mods, is because on the 03s aftermarket air filters will cause egr codes cause it plays with the maf readings. giving certain situtions, egr codes can and will be set.
