Unplugging your EGR RECAP!

Polaraco · 10-27-2008, 10:17 PM

RECAP

1. Pulling the plug on the EGR will cause better mileage and fewer regens. General concesnsis is 2 MPG improvement.
2. It will not harm the components down stream. It will actually help them
3. It will generate a check engine light because the computer sees pieces of hardware missing. You will have to deal with it until a code free EGR solution is found.
4. Just unplugging the EGR will not allow soot to build up. Experiments after 6000 miles showed the exhaust pressure is enough to allow the exhaust pressure to bleed off the soot and condensation.
5. This is reversible and will leave a code stored in the ECM. The dealer may or may not see it. Depends on how thourgh he is. This means you can unplug the EGR and go to the dealer with it plugged back in.
6. Some earlier trucks act strange in the beginning. If this continues, you'll need to remove the flapper valve in the intake, or get a later update on the ECM.
7. Unplugging the EGR with a DPF delete has some short term effects on your truck. The two systems are tied together but work independantly. If the problems persist, then you have other problems which we will try to help you with.
8. DO NOT keep plugging in and unplugging the EGR. It confuses the ECM
9. Codes usually generated- P0405 and a low pressure code.
[10. Codes can be cleared with an Edge or a PMT. Some have had good luck with running with the codes cleared and some have not. It's possible the flash level is the problem. Clear the codes before you start and see how it
11. Best Minimum Flash levels.

DO NOT DELETE THE CODES IF YOU CAN. Your fuel economy can be effected and it could throw your truck into a limp mode when changing climates. Temperature plays a major part in this.

Polaraco do you still have all that stuff under your hood or did you do the EGR cooler delete and EGR delete to clean up and lighten under the hood?

I'm confused. I didn't know you could just unplug it. I thought you had to block it off. As it sits right now my truck is completely stock like it left the lot. Can I unplug it right now with no ill effects? I have a dpf delete but I've never had the time to put it on. Will I need to plug it back up after doing that?

As long as you have the current flash. If you unplug it and it starts and runs fine then your ok. If it runs funny after you start it plug it back in and go get the truck flashed.
