Green Wrench with Full EGR Delete

Hello everyone. Before everyone bashes me for not searching the forums for this problem, I have, just to clear that up.

I have an 08 F250 and have had a DPF Delete and EGR blocker plates on for a couple years. I have an SCT Livewire 9625EOR for tuning with only canned tunes. For the most part, I am satisfied with it and the canned tunes. I recently decided to do the full EGR delete and Remove the EGR coolers as well and install an intake elbow. After install, the little green wrench came on the display but truck seemed like everything functioned properly. I plugged the EGR back into the wiring harness and the wrench went away, unplugged and it came back. I flashed my truck again and made sure that I selected "EGR Components Disabled", but light was still there.

I went to the forums thinking that surely there was a fix. The only fix that I found was paying for a custom tune. I went back out to my shop and grabbed my Ohm meter and checked the resistance between the pins on the removed EGR valve. The only solid reading I got was between two pins and it was 4.7Kohms. I went to Radio Shack and bought a package of 1/2Watt, 4.7Kohm resistors. I installed a resistor in the wiring harness to correlate between the two pins on the EGR valve. The result... no green wrench light!

So, I have drove truck around yesterday, around 100 miles, and all seems fine. My question is, does anyone know if this has been tried before and could it cause any potential problems? Less that $2 for package of resistors vs $75+ for a custom tune. Thanks.

That's a pretty clever idea. Any update no issues since the mod? Im basically on the same boat. Also what pins did you jump with the resistor?

Had the same issue when I did my 08 6.4... Picked up this info from another site, installed and no issues so far with about 10k since delete..

"I used two 1K 1 Watt Resistors from Radio Shack to Satisfy the PCM that
the Throttle Motor was plugged up & working

I put one resistor between #1 black wire & #3 blue wires.

I put other resistor between the #2 green/white wire & #4 green wires."

I have had no issues yet. I used only one 4.7Kohm resister. I am not sure what pins. I know that I started the pin next to the rounded side of the connector and skipped the next and went into the third. There was a pic with the original thread of resistor in connector. Wonder why a second resister might be necessary if what I did got rid of the green wrench light?

Did you use the EGR connector or the Throttle Body motor connector?

Very good idea! You just gave me an idea....I have several 6.4 trucks, and I want to remove my Mini Maxx from one of them and install a DPF-R+. However, even though the DPF-R+ shuts off the EGR, you need it plugged in to avoid the CEL. I fully deleted the truck and do not want to install the EGR Valve to avoid the CEL. I bet this would work for me too.

When I did mine, I left the EGR Temperature Sensor (from the top of the cooler) plugged in and used the Resistors in the plug for the EGR Motor.. Not sure if both Resistors are needed, but no ill effects so far.. I say roll with it..

I also first used the DPF+R 4.0 and worked like a charm.. From what I understand the DPF+R requires the Exhaust Sensors to still be plugged in, just not in the pipes.. (that's how mine is now)

Actually, I am still using the DPF+R for the DPF / DOC Delete stacked with a Superchips Tuner until I save up the cash for another Tuner.. Hope this helps..
