Hey all, got a 2006 f-250 6.0. Just pulled my egr valve to see what it looked like and cleaned it up a bit while it was out. Popped it back in and decided to disconnect it. Disconnected it and everything ran fine. Drove to Napa about 5 miles away no problems. Came out of Napa and fired it up and my check engine light came on. Is this normal when you disconnect the egr? Got the 2 trouble codes I figured I would get on my scanguage. (P0403 and P0405). I am just worried about that engine light. Everything seems to run fine though. Got 35,500 miles on the pickup as well. Any thoughts?

 

Yes those codes are very common with EGR Valve unplugged especialy 05+

Best thing is to Deleate EGR Cooler or Plug it and Keep the EGR Valve Plugged in to keep the PCM Happey if these steps are taken and light persists you will need a Tunner to rid the CEL

also the truck may go into a Limp mode with a CEL

 

Normal to get CEL with it disconnected with your truck.

 

Well guess I better plug the darn thing back in. You gentlemen know a approximate cost of a egr delete? Parts and labor.

 

oil cooler kit and delet runs about $2500 if done right and if you can find a shop to do it.

 

Not something that I would advise doing since you are in California.

If you insist on taking the EGR out of the loop, do it via tuner and just turn it off electronically. That way it's easier to bring it back when you go to sell the truck or if you go in areas that really police emissions.

 

Well my pickup is registered in Oregon if that makes a difference. Just temporarily in California. Would the SCT tuner disable the egr system?

 

Legally no. Federal law trumps things here. What most people won't tell you is that even if you don't have emissions testing, it is still illegal for you to remove the emission equipment. Now the odds are higher of you getting caught the more aggressive the area is that you are in or that you travel in, but if it came with a cat, egr etc, you can get in trouble from removing those. And shops that do the delete if they are caught, I have seen places get closed down over this.

I don't know if you seen the show TRUCKS!, but the custom muffler shop that they use there won't do the deletes at all. For the very reason that I cited and this area isn't really a go getter for emissions violators at this point in time.

What a tuner will do is shut the valve off. So it's electronically out of the loop. Cheapest, easiest way to deal with the EGR system and to get it back to normal when you have to. Very hard to do that with a true delete kit. Bypass would be the next option, little more costly, visuals hold up. If not done correctly though the truck isn't all that fun to drive.

 

Entirely correct.

If an individual is caught doing this, the fine is $2,500 per compromised device up to a max fine of $10,000 and, if a business does it, max fine of $25,000 under Section 203(a)3(A) and (B) of the EPA Clean Air Act.

Just sayin'...........

 

California is the Worst Place for that stuff

 

The one argument that I would personally accept for deleting the EGR system (not thinking legality here) is what the EGR system can do to the turbo which could lead to undesired boosting conditions, which could lead to head issues.

Now even with that argument, here is the kicker. Quite a few people here know a few things to do while driving every once in a while to help clear that all out. Now, you have to be pro-active a little bit, especially if you got the vehicle as a commuter/ego stroker versus a true working truck. But these little extra things that you have to do are not like digging a ditch to China and actually are an "excuse" to have a little extra fun with the truck.

I just think two things (at least have gone on here).

1. People think all things EPA related are evil and serve no purpose whatsoever (debatable)

2. People have just gotten too lazy. Both in terms of really researching their purchases and being pro-active when their needs/wants to exactly mesh with what a vehicle was designed for.

I have less sympathy for people that got these big trucks as commuter/ego stroker vehicles. It's your money, you can do with it as you will, but it's all the bitching that comes after that gets me. Do your research people.

One caveat, I'm in no way implying anything of the original poster of this thread, most that have been around know that I tend to get into a little tirade with these EGR threads, most of the time though I tend to focus on the legality of it all.

Sorry OP. I just can't help myself on occasion.

 

Recyclying sooty diesel exhaust back though & deal with cleaning it out or delete and your mpg should go up 1-2 mpg, just saying...

 

The thing that Bugs me is things like an EGR System there just nothing good about it. Whats to gain with it Its Basicaly just a Detune of the truck Worse fuel Milage ruins all the sensors within the intake manafold. Or if the EGR Cooler Blows the HG may let go. I can Unplug an injector and produce Less NOx

Stuff like Cat and that Im Good With it Cleans emissions up thats Great and it does it without a negative effect or very little negative affect to the Owner. If it Clogs up its not a Catastropic Failure like A EGR Cooler Blowout can Be.

They just need to regulate vehicle emissions Diffrent who want a Emission Componet/s on there vehicle that when it Fails it Kills the Engine.

IMO ALL the Emissions need to be controlled in the exhaust ONLY after it exits the Engine. Just done in a Way that there is NOT the Possibility of a CATASTROPIC FAILURE.

When an Emission component Can Fail and Take out a 10K Engine why would anyone want that on there moter. Its not like Uncle SAM steps in and Flips the Bill for it.

Lower Emissions we all would benifit from Thats Awesome The emission control componets shouldnt be such HIGH Risk either though

LAND OF THE FREE YA RIGHT

 

Exactly my point in the Past

EGR System = Bad Fuel Milage

How much MORE emission gas is produced to get all that extra Oil pumped out the ground and then Oil Refined and to the Pump since everyone will refuel Sooner


Is it Really Worth it do they think they are putting a dent in the emissions produced??????

I tend to think its a Control thing Back to the Land Of The Free thing

The technology now there should be very little emissions emited from a vehicle without the possibility of Catastropic failure

 

In my experience with people that I personally know, when an EGR goes it's usually because of the oil cooler, not because of the EGR itself.

EGR works, it works on cars in accomplishing it's goal no problem. The sticky issue with our vehicles is that we have different fuel and that fuel doesn't exactly play nice with it. It can work and it does work. I throw 40% more fuel at it then most people on here and I'm still on my original cooler. That's the issue there. That's were people have to have a little bit more know how, especially if they want to use this vehicle as just a point A to point B and those 2 points are pretty close together.

Everything on these newer vehicles you run the risk of their being this cascading type of failure. One thing goes, then another and on down the line. That's the booger of owning a techie vehicle. Even worse with the newer vehicles.
