Question for you electronics mad scientists?????

[james.jeleniowski]

I unfortunantly have a CA emmissions 2004 6.0 I was wondering if anyone knows a way to wire a dummy plug for the intake butterfly valve and EGR valve so they dont throw a code?????

I know it can be done. Somehow voltage goes in and some how on one of the wires voltage has to be sent back so the Truck knows its there and functionable. So somehow if you conect a wire to another it must comeback OK right???

Intake butterfly valve? What is that? I dontt have my egr valve in place and I dontt get any codes.

Welcome to the org by the way.

Well I unplugged my EGR and threw a code. On the 04 there is a spacer between the intake and the elbow. Inside is a butterfly valve or so I am told by CFM Plus

That's correct, but you can remove the butterfly and it's exactly like the 05+ trucks. Unfortunately, you need a tuner to turn off the CEL since it's not just detecting EGR valve position but it's also detecting EGR flow.

You can take out the egr valve and leave it logged in on top of the motor. That will keep the CEL off too. I have an egr delete and I dontt not throw any codes. I do have the valve on top plugged in but itss not in itss hole.

That won't work when the emissions folks perform a visual inspection of the engine. The EGR valve will need to be installed and electrically connected.

PS. We have similar emissions here in Arizona.

So he could just put.the.egr valve back in. Actually as long as the valve is working fine he could leave it in all the time.

Exactly. For any long term EGR delete, he would need a tuner to turn off the CEL.

So what tunner will turn off the CEL???? I want to do an EGR delete, so If I delete the cooler but leave the valve that wont effect anything right? It will be like not having an EGR at all cause when it opens there is no exhaust to flow through

[WarChild]

Thatss correct. I have an 04 with a egr delete valve is plugged in, sitting on top but it would do the same if it were installed, no CEL and my programmer does not turn it off.
