Hey fellas, I hope I'm posting this thread in the right place, I read the rules but I'm still new here! Anyways, I've been doing a lot of work on my 6.0 2004 Ford Excursion lately, and recently installed my Sinister Diesel intercooler pipes and intake elbow, and had to remove my throttle body completely to do so. I know that the 2004 models throw codes when removed, and that's what I'm here for. Mine isn't dogged down and actually runs even smoother with my new piping and intake, but I want to get rid of this code. Is there any tune out there that can erase it? For some reason my Edge Insight CTS2 sees the code, but my SCT X4 flash tuner doesn't see the P0488 code. I know people have discussed this topic several times, but after hours of reading through posts I never found any solution to this. All I need is a way to delete the code because I don't like having my CTS2 with a trouble code for something I did on purpose! Any help would be awesome. Thanks!

I wanted to delete that elbow on my 04 as well. I unplugged the connector going to it and had that code pop up soon afterwards. I never looked into what the solution would be. Possibly a custom tune? Or maybe upload a different strategy that doesn't acknowledge the butterfly? I'd be interested to find out what is needed myself.


I'm Nick as well

 

Most people just remove the butterfly flapper screwed to the shaft and leave it in place and plugged in.

 

That's what I'd do....

They probably could write it out or even write you to a strategy that doesn't use it, but what that suggestion should do nicely.

 

The only problem with the solution of removing the plate is that the aftermarket elbows are the size of the 05' and up, so you have to remove the throttle body entirely in order for it to even fit and line up correctly.

 

Why they leave them in place, the removal makes the code pop. Elbow looks great, but probably doesn't do much for performance. Have you called the maker.... maybe they have a solution?

This if for a 6.4 but apparently several guys have stopped the code from coming by installing a couple of 1k resistors
