how to keep codes clear
Just installed a bunch of upgrades to my 05 6l excursion. some of them was a
CFM intake elbow Gogo stage 1 polished & ported manifold with egr delete ARP studs oem head gaskets, oem oil cooler, garrett turbo upgrade, blue spring upgrade, whatever other upgrades available oil lines fuel line, and a sct tuner with some custom tunes. The custome tunes I am now told will not ckear the P 0407 and the P0488 codes. other than putting back the stock throttle body and elbow is there any way to keep those code clear. I also have a P0688 code but was told that is something else. thanks

I removed the one part off the throttle body and pluged it is but still got the codes the other part is kind of big so I dont know that I can remove it from the throttle body and sit it on the motor. I was wondering if someone had done this before with a resistor of some sort.

one plug on each side I'm guessing one turns the butterfly shaft and the other is a position sensor?

plug the harness back in and just remove the butterfly. The P0488 code should disappear. The P0407 means the EGR circuit is shorted to ground.

It looks like the only way might be to remove the CFM intake elbow and put the stock throttle body and stock elbow back in. I put the stock tune back in and ran it a few miles. The engine light came back on but the only code that came up is the P0488 throttle..... code. I dont understand why the other two code come up with the custom tune. I'll talk to those guys again but Im not to impressed with them. If any one has some other suggestions on how to clear this code without the throttle body in I'd be willing to try I looked at taking the unit off the throttle body and trying to connect them with a small shaft but looks like too much to mess with. I wanted to keep that other elbow in cause it is tapped and threaded for a boost sensor that we installed. thanks for all the advise it really is alot of help.
