This has to be done via custom tuning or a hardware network interface.

Now I got, I think.
So, based on what PSD has said, the '05 (my CA model) will not throw a code when the dummy EGR valve is plugged in, but the '06 will? Right?

BTW: Don't belittle yourself. You are not dumb. You were smart enough...just to ask.
As a side note: We all know that there is no dumb question, right? I would just like to add that while that statement is generally true...some of the answers can sure be dumb enough...

After a re-read of usroute66 I'd better make a list.
- Buy dummy EGR Valve
- Unplug original EGR Valve while the engine is off and key in off the position so that the installed EGR Valve is permanently in the closed position
- Plug wire into your dummy plug so that the signal will be sent as an operational unit.
- Secure (zip tie) the dummy unit to a close, convenient location so it will not move around.
- Cover / tape over plug location on original EGR Valve.

Can the SCT disable this scalar, and leave rest of the tuning close to stock?
I am planning on never running the EGR, but don't like warning lights and would like to maintain the ability of the CEL to warn me if something is really wrong.

Thanks KW...that is in good old plain English. Thanks! Now, comes the big bad stealership. I probably should re-install the EGR factory set up before any warranty work is needed, right? These days, it seems they are looking for reasons to not do warranty work.

I unplugged mine about a month ago (05 Calif.) and the CEL went on after driving a few miles so I plugged it back in. The CEL went out by it self after a couple of days. Maybe it has a auto reset after so many key on/off cycles?, as long as its plugged back in and working properly.

If the EGR system is to be removed or disabled, the code with either have to be manually disabled in scalars or simply lived with.

Thanks for all the info. I did disconnect the battery and the CEL went off briefly. It is now back on. I would assume the only disadvantage of driving with the CEL on is if there is another non related issue with the truck and the CEL is on, you wouldn't know it.
Is the dummy EGR discussed in prior posts a non working valve offered by Ford? Do they manufacture this as a remedy to the issue at hand? If so would they have a flash to disable the code as an alternative?
Thanks again,
Cheers

KW...see the confusion regarding the word "dummy"...makes it sound like a valve with no guts in it, sorta a unit that matches up with the right pin settings and locations.
Brick...a dummy EGR valve is another EGR valve, just like the one mounted into your engine now that will then be plugged in to the connector plug that you have taken out of the EGR valve. The dummy part is that the computer thinks there is an EGR valve hooked up to the connector plug, so then it won't throw codes. You need to visit your friendly dealer and order an EGR valve and they will be happy to take your money.
As other post have indicated, the unplugging would be considered an EPA no no, and is in no way a remedy that Ford would support (at least not publicly...maybe secretly they would like to throw the thing in the river
). I would assume that the only way to get rid of the CEL, since you did not hook up the "dummy" valve, is to reconnect it, take it to the dealer, have them clear the code, buy a dummy valve, take it home and then follow the directions that KW above laid out.
Right KW?
