I will have to look at that. I tried to pull the grill of once or twice but was not able to because the bumper does not allow the grill to be pulled away. I'd rather not pull the bumper if I don't have to.

I've installed a ARB on a '05 KJ,same grill style as yours and put the grill on after the ARB was on,really wasn't hard.I also pulled my grill on my '02 with my ARB still on when I replaced my radiator a few months ago.

I feel you about pulling the ARB off,it's not light with that winch in it.

No more CEL’s. Best part is, they would never know even if they fell over it.

I probably need to get off my arse and finish putting together the SEGR. But how do I know if the POS EGR is stuck closed or stuck open?
Does anyone know the potential for affecting emissions tests? They are mandatory in my county even for diesels. I know it turns off the CEL after shutting off the EGR but what is the actual tailpipe result? When I had my F350 checked they plugged into the computer as well as checked the pipe.

I know there may be a gauge flash issue that is causing the appearance of serious overheating problems but the dealer claims my VIN is not associated with that recall. Is there any chance the stuck EGR or FCV is contributing to this?

(And I still don't know if there is any relationship between any of this and the P0299 code that seems to have appeared at the same time)

Thanks,
Chris

If I install the SEGR and clear the P0401 with my scanner will the P0401 reappear?

Turbo Tim · **Posted:** Tue Aug 12, 2008 12:36 am

I can't find P0401 in the list. I can find P0402 which is low EGR flow.
The answer is YES.
The SEGR will fix any and all EGR, FCV code reporting as it disables them both and spoofs the computer. The MAF and all other sensors have to be working properly. If your worried that the EGR is not shut all the way, with the SEGR wired in, you can also install a block-off plate to be 100% sure it is off.
I have over 30K miles on the prototype and no CEL’s!

Don’t take my word for it, ask others that have done it. Ask those who have installed them. I’ll even go as far to say that I don’t know of ANYONE that has put one on and then taken if off because they didn’t like it!

As far as emissions for diesel’s, to my knowledge as of today, there is no possible way they (the fuzz) can detect that it is not working at your standard state or private owned inspection station.
Yes they can tell on a gasser (patoie), but not on a diesel. Here in Arizona all they look for is to see how black the exhaust is when you stomp on the pedal and how fast you can pee away $27.00. Good check. Sometimes they scan for codes. Well that’s covered. No codes here.
99% of the dealer mechanics can’t even find their own butt with both hands when it comes to the CRD and yet some people are worried that “They” will know right away. Good luck.
It’s your call but the pack is in front of you.

Thanks for the info, but you may as well posted this in Greek my friend. Wouldn't know where to look for an EGR and what to do with it once I found it.

Well, you have come to the right place! Ask and you will get help here. If you want to learn, do it right, fix the short comings of this great little SUV, you have struck a gold mine of help and information.
If you need help wanting to do this, just ask. Maybe some in your area are familar with this and will step up and help. It's worth asking. Can't hurt.
You may even have to plan a weekend trip to someones area to do what you want to do. Worst case is you spend the same amount BUT you did it, and hopefully learned something doing it.

I could not have contributed to doing the SEGR without the help of many here. (Many thanks to all and you know who you are).

Well, JL Rockies, I must say the following statement is absolutely true:

I'm constantly amazed at how helpful the folks in here are.

I'm hoping that this EGR issue will be fixed by the SEGR and will be the last engine-related obnoxia I have to endure. If so, I will be happy with my mule.
Oddly, thus far my wife's 06 has had NONE of the issues my 05 as had - and she has more miles.

Concerning your feeling you don't know anything: I have overhauled numerous gas car and boat engines over the years and could perform most any repair on older cars. I thought I knew something. But I went all diesel in the past few years (F350 and 2 CRDs) and have had a very frustrating learning curve associated with it. It's a whole different world and this forum has been the equivalent of taking an online auto shop course.....except the last time I took auto shop I had a beat up 1970, $500 Ford Maveric & not a $25,000 4X4. I hope I graduate soon.

EGR: Exhaust Gas Recirculation = takes a bit of the exhaust and feeds it back into the engine in an attempt to more thoroughly burn the combustion by product. There is great controversy as to whether or not it has much positive value in this particular engine. The overwhelming opinion of the members of this forum is that in this particular case, it should be shut off due to a number of factors including the poor design of this EGR unit and the high level of soot from the diesel engine.
SEGR: An electronic box that was designed and pieced together by folks on this forum and then sold as a kit to other members. (I think it was primarily Turbo Tim, UFO, LocoCRD who were responsible for bringing this to market) This ingenious box hooks into your wiring harness and shuts the EGR unit completely off. Normally, if your EGR is unplugged it will turn on the check engine light (CEL). However, this magic box fools the computer into thinking it is working fine so the CEL does not turn on. This should mean the emission checkers will not see any error codes in your emissions system due to the EGR being off. I am hoping that having it off will not affect the emissions at the tailpipe either (I have yet to install my SEGR) ...but based upon another thread I recently started, it sounds like it is not enough difference to matter.

And that is the extent of my knowledge on the topic.

You get to move up to the head of the class. Very good. Close, but good.

The EGR debate comes and goes, but was never on the engine in the first place. When it got blessed to be in the USA, it was with one little EPA stipulation: Put on an EGR! (or else). So this system was patched on and we were able to unpatch it. Note that they way it was put on is why it will set a CEL when it checks itself and thinks all is not right. That is where the SEGR comes in and combines a few signals to the computer is happy that all is well.

Very good, now get busy and have a SEGR party.....

The AC condenser fan went out and they want $500 to remove my ARB to get to it. I told them that I would pick it up and return it with the bumper removed. Total quote: $1450

$770 P&L on the EGR

You do not need to remove the ARB bumber to get to that fan,the grill still comes off nicely and you have plenty of room to work with still.

You're a better man than I. I could not even get the grill past the headlights let alone have the clearance to "unhinge" the bottom clips. I'll have to pull it, but it means my Jeep can't go in for service this week.

The way I see it, the Jeep was flawless up until now with 61K on the ODO. This Jeep was the first vehicle I've owned that was not a Toyota (I used to work for them). I know how much domestics squeeze their suppliers until said suppliers can't afford to make quality parts. I grew up in a Ford family and was raised to believe that after 50K miles domestic vehicles will begin to break, so in my world, I am ahead of the game. I normally do not buy extended warranties because Toyotas don't break, I did buy one this time because it was a domestic. Of course, the warranty doesn't cover EGR, but I digress.
My plan is to let the dealer do what needs to be done, pay the bill and I should be good on the EGR for another 61K miles. I am sure many other things will break in the mean time and hopefully they will be covered under my warranty.
I appreciate the ingenuity and obvious passion you guys have for this, but the modifications you guys are doing just don't make sense to me. If I don't trade her in when the bank is paid, the Jeep will get subjugated to being my play vehicle when I buy a car for my DD.

The mods are there to remedy weaknesses in the vehicle. My EGR will never fail because it is disabled by the SEGR. As a result of this mod, my vehicle's oil will stay cleaner longer, my intake will be less likely to clog, and I won't have to worry about getting stranded. The mod is well worth the peace of mind it brings me.

Thanks professor!
It does seem strange though: It would not have taken much testing in varying conditions to show the system was designed improperly.

Now....whats the quickest, easiest way to block that dangnabit EGR off once and for all? I think it may be stuck in the open position.

Is it possible my EGR is stuck closed and exacerbating the overheating problems?

I will quote myself below for emphasis regarding EGR and engine temperature.

Most people think that EGR is supposed to lower combustion temps, but that's not being very specific. It's supposed to lower peak combustion temps that occur in microscopic areas, by introducing an inert gas - a punching bag for other molecules, so to speak. It's not even relevant really, since EGR is used at low loads only, not when climbing a long grade at high load. In our application, most of the increase in warmup time is because our EGR is normally cooled by engine coolant, so the heat that would otherwise be dumped into your coolant system goes out the tailpipe instead when running the ORM.

Man,
You sure do take a hit on MPG driving around with a buggered-up EGR. I've lost 4 MPG drivng to work this week. Unfortunately, I don't have the $700 lying around for the repair so I'll have to wait unti Sept probably. It would be cool if I knew how to fix it myself, but I have no marketable talents.

I have a brand new EGR on the way that I bought on Ebay from Hall's Auto for $150. That's a huge savings over what the Jeep stealer charges.....might be worth giving it a shot yourself for that kind of money.

I finally finished replacing the EGR. All codes have been cleared an code reader now says no codes are pending. This was apparently the problem with the codes.
Now, if I can just figure out the overheating problem...... :roll:

Yup, another happy customer with a P0299 and P0401 code!
