P2262 revisited

[MullenaxM]

Just an up-date,



After about two months have gone by with the new flashes, so far it seems to be helping the P2262 trouble code issues.

Hey, Mike. I wondered what happened to you. Where've you been?

 

[MullenaxM]

I'm here, busy this time of the year. Been doing a lot of trail rides (Horses). Also summer heat = broken trucks = Busy at work. I've been in my "setting on the bench and monitoring from the side line mode" But I'm still here.

Awesome Mike... I am taking my truck in next week... They cleaned the turbo 500 miles ago and now the code again. . I want to talk to the mechanic this time. . I will bring your post with me to give to him not trying to insult him. . your blog was over the top. . my email address is -- email address removed -- if you can send anything else that you write about. Everyone is quick to blame the Edge system but I am not running additional power settings that would give the motor more fuel making more soot... .

Taken care of the issues, or hidden the code? Here's why I ask.

I had my '07 C+C to the dealer a couple weeks ago to find out why my EB keeps sticking on. It will stay on and cause an incredible rough running engine with tons of black smoke. More smoke than the Smarty would make on my '04. 5. Dealer hooked it up and found a bunch of flashes that I didn't have so they did them all and sent me on my way. No help, same problem. I went back a couple days ago to give them another try. No luck. Dodge saw thru the wi-tech that I had a few other codes related to my EGR and DPF deletes, but they didn't know why. Dealer tech played dumb. Anyway, they couldn't find anything wrong with the EB so Dodge said it's gotta be the EGR. Delaer didn't tell them that can't be the case 'cause there's no EGR. I took the service manager for a ride and then the tech (reg cab). I managed to get the EB to hang up for each of them. Got back to the shop and checked for codes with my Insight monitor. I finally had a new one, P2262, for the first time. SHut the truck off and hooked up the wireless. Guess what? No 2262. It disappeared when I shut the truck off.

Last night I reinstalled the EGR and plugged the DPF pressure sensor back in so now I'm totally code free. Went for another test drive. The first time I hit the EB, it hung up. Checked for codes, got 2262. Drove around for a while waiting to see if anythign else would turn up. Nope, everything else normal. Got back home, check to see that 2262 was still there BEFORE turning the engine off, it was. Turned key off, back on to check and it was gone. Not stored in what Edge calls "Historic" codes nor in the current codes.

Called delaer service manager today to tell him what I found and he's stumped as to why it will throw a turbo codes w/o setting the CEL and why it's not stored.

BTW, EB never hung up until after I did the DPF delete at 65K, which was when I got a new DPF compliments of Dodge. I removed the EGR after the hangups started thinking it would help clean itself out. I didn't know Dodge would be looking at it thru wi-tech or I would have left it. Anyway, the tech said he kows no reason why the deletes could have anything to do with my troubles... in case anyone reading is thinking they do.

Thanks for any input you may have.

A couple of things come to mind, first, the P2262 trouble code is a two trip code, meaning that it takes two complete drive cycles for this code to become active and turn on the CHECK ENGINE light. In the first drive cycle if the ECM sees a malfunction of the turbo it will set the code as a pending code, in the second drive cycle that the ECM sees a turbo malfunction it will set the code as active and turn on the CHECK ENGINE light.



It is possible that your Edge Insight is reading the pending code as an active code and that would answer the question as to why no CHECK ENGINE light comes on. Since your Edge Insight plugs in to the OBDII connector it might be putting a glitch on the ECM BUS and erasing the trouble code. (?).



I would suggest that you remove the Edge Insight and go drive the truck and see if you could get the turbo to stick for two drive cycles and see if the CHECK ENGINE light comes on. If it does then you can check the codes with the “Key On-Key Off” method.



The Dealer Technician should have taken the StarScan or the Wi-tech on the test drive with you so he would be able to monitor the turbo slide ring position when it was sticking. Also he would be able to see the engine run time when the fault occurred.



As for a repair, since you have a Dealer that is willing to ignore the fact that you have “Modified” the Emissions Systems, I would see if you could get them to clean or replace your turbo.

The insight shouldn't be erasing the code. Only the Attitude can be set to do that automatically, but I won't rule out a glitch. I can erase codes "manually" but not "on startup" like the Attitude. I'll try unplugging the Insight.

The Dealer Technician should have taken the StarScan or the Wi-tech on the test drive with you so he would be able to monitor the turbo slide ring position when it was sticking. Also he would be able to see the engine run time when the fault occurred.

The Wi-tech was still in the truck but not close enough to the base to connect. After the 2nd test run I unplugged the Witech and checked codes with the Insight. Then plugged the Wi-tech back in and nothing. We didn't plan on hooking back up to the Wi-tech until I found the 2262. Next time I'll suggest they monitor the slide ring position.

Well, they ignore mods but they don't foot the bill for much. They won't have any problem turning it in for warranty, but they won't do it themselves.

EGR is back in and functioning the way it should. DPF is going back in this morning yet.

Thank you for your help.

Just so I don't hold back some valuable info, I now remember why I did the DPF delete in the first place. I still have P2084, which is an EGT sensor code. That one was present before/after the new DPF went in and is now back. Sounds like I need a new one. I remember thinking that's probably what caused the first DPF to clog at 65K. I'll give the DPf credit though. When the EB stuck yesterday, it trapped all that beautiful black smoke and I'm the only one who knew the truck was making any.

2269 is there as well. Can't find any info on that one. Both found thru key flippy thingy. Insight is unplugged. 2262 same as before, there on Insight when running, gone afterwards. I'll stay unplugged for a while.

Oddly enough I didn't get an immediate regen, the counter is over 300,000. Won't take long for the DPF to plug if the EB keeps sticking.

 

[MullenaxM]

DTC P2084 is a DTC that will suspend a regeneration event, thats why you didn't see a regeneration.



But what would have me worried is that the DTC 2269 is a code for excessive water in fuel.

You might want to pull the fuel filter off and see how much water is in the fuel system. My best advise is to not ignore this issue,as you probably already know, water in fuel on this engine can cause big and expensive problems.

MY WIF light has been coming on for the last 3 weeks. I've drained the filter countless times, changed the filter, and gone thru 2-3 tanks of fuel since the water showed up. The light is currently off. It may stay off for a day or two, sometimes for only an hour or two. It's been driving me nuts. The fuel since the bad batch has come from 3 different sources. Is there an issues with the breathers on these trucks picking up water when driving thru the rain. It was raining like a SOB the morning I first got the light. Barely a sprinkle since. Maybe my beautiful black fuel tank is getting a lot of condensation. I've got nothing out of the ordinary as far as my fuel setup is concerned. Shouldn't be anything other than bad fuel, but 3 tanks worth of water from one fill up??? Trust me, I'm concerned too.

I remember the 2084 from before I removed the DPF. What I don't recall is if it was there before the DPF was replaced, I think it was. I'm gonna have to call the service dept tomorrow and see what was done with it. I know the sensors are all original yet.

 

[MullenaxM]

P2084 DTC is related to the #2 exhaust temperature sensor, thats the sensor that is between the NAC and the DPF. More than likely the sensor will have to be replaced.

 

[Cattletrkr]

So after 3+ hours at the dealer today, here's what I know. The test that is triggered by P2262, can't be run on the C+C's. Only "test" is to replace the turbo. New one is on its way. 2084 went away on it's own. Now P0546 seems to have replaced the 2269. Yay!!!

Now the truck does what it did before the DPF delete. Idles up and stays up, same for the EGT. 600+ at idle indefinently. Won't drop below 550*, kinda hot for a shut down, but it is what it is. If I can shut down before it idles up the EGT will stay normal. Sounds like it used to sound when in regen. SO far it hasn't stayed up while in motion, but it did that before the delete so I expect that maybe tomorrow. That's kinda fun.

EDIT: Dealer said I had a code for water in fuel which I assumed was the 0546 since the 2269 went away and the 0546 showed up. 0546 is for the EGT sensor, only now it's sensor #1.

Mike,

Just bought my 09 3500.

Truck has 600 miles on it when I bought it. there are no problems but I want to know do you think my truck has the latest flash?. . and is there any TSB's for this truck?

 

[HBarlow]

Cattletrkr,

I don't understand when you say your EB (VGT) is sticking closed and causing heavy black smoke. How does a closed exhaust cause excessive smoke?

Are you sure the ECM is not confused somehow and activating a regen? The rumbling sound when in regen sounds a little like the sound at idle when the exhaust brake is activated. A regen would be consistent with black smoke and the high egt when attempting to shut down.

 

[DieselLady]

Hey Harvey,
The VGT on the new trucks is a ring that opens and closes to accelerate the flow of exhaust to make the turbo spool up faster at low speeds. If it sticks, not necessarily in the closed position, but sometimes in the open position, it will not cause the turbo to spool quickly and the lag will cause the smoke. I assume that you know that the e brake is just the computer closing the vgt,( this is actually a big ring on our trucks), when you take your foot off the throttle.
Also, the Regen is done by turning on the injector just at the beginning of the exhaust stroke. It allows the fuel to be super heated and go into the exhaust pipe system along with the exhaust. This will not create any noise that would be noticeable at all.
This is how it was explained to me. IF you have any info that I don't know I would love to hear it. There is always more to learn.
But having a sticking turbo surely can cause excess smoke.

You can take your truck back to the dealer and request they hook it up to the witech and check for flashes. The new policy is if there are updates available while you are in warranty they will do them for free. No need for a TSB as the case used to be

The truck wasn't recognizing the EB as stuck, so it would fuel right thru it. A closed exhaust will cause smoke the exact same way a severly clogged air filter will. Limit the amount of air going thru the system. This was identical to what my '04 did when the EB hung up on that one. The "pop" when it opened back up was a dead giveaway.

Since the new turbo went in, everything has been the way it's supposed to be. Except now the truck recognizes the DPF delete and throws a code that it didn't before. Not a really big deal, but a little annoying. One of these days I'll get an XRT or Smarty to take care of that too.

A 6. 7 that is operating properly will never blow smoke. Black smoke out of the DPF means it is cracked and is no longer doing it's job.

Yep, that would be right from the San Francisco Bay!

You beat me to it :-laf:-laf
