EGR question

[jonathanwayne18]

Does anybody know if there is another programer other than the sct that will clear the check engine light after the EGR delete?

[Lilpooh]

IIRC, SCT with is the only one to turn off the CEL and keep it off.

Why wouldn't you go with a SCT with custom tunes? It's the best programmer for the 6.0.

[jonathanwayne18]

Well i just wanted to see what my options were sounds like there aint many

H&S Performance Mini Maxx will do it as well. Thats what I have.

[jonathanwayne18]

What about the insight i know its not a programer but i'd rather have a custom chip and the insight and it says it displays and clears diagnostic trouble codes

[azkcr]

Displays and clears, yes.
But the code will pop up once you start it again. But with custom tunes from the SCT the EGR code can be ghosted.

Im not gonna say who told me this because he is respectible around these parts but i had a shop owner tell me he has put the egr valve just the valve not functioning back in and the code went away

[jonathanwayne18]

Any thoughts?

The valve has to function, as it is a code that is generated because the EGR valve is not detecting 'flow'.

If there's a way to rig the valve, or short it or something, to fake a good 'flow' value or voltage, it might be possible, but the valve has to send some sort of signal back for that code to not come up.

If anyone knows what kind of signal the valve sends back (steady, pulse, sweeping value, whatever) I could probably easily rig something up to fake it, but I haven't looked into it at all. I just got the Mini Maxx and disabled it myself.

Yep. It all depends on the year of manufacture of the engine and the strategy.
Typically the 03-04's don't throw the "P0401: Insufficient EGR flow detected" code near as much (if at all) than the later years. The 05 is more "sketchy" if it will throw the code or not, 06-up will.
After I installed my egr delete (06 truck), I thought I was good to go since I did not get the P0401 code for close to a month after the fact. The code, over time, comes back quicker and quicker. Now, 6 months later, If I clear the code and drive it for any length of time beyond warm-up in the city, the code returns.
The way that the valve reads flow, it would be real difficult to "fake it."
