Help, 2007 dodge pickup 6.7 liter cummins, seemed like the motor was loosing a little power when towing up hill, shortly after, the ecm went out, replaced it and had pronlems with the check engine light coming on low voltage code, replaced the batterys. the light come on again it was egr valve, now the light came on again going back to the dealer next week. this whole time the power is still an issue, especially when towing uphill. every time I had it in the shop the techs say there is nothing wrong with the truck, its fixed. but there is something definetely wrong. I think they are just relying on the ECM codes to diagnose the problem.

Are you just making a statement or asking a question on why it is losing power?
If you think you are under power, you could change the air filter and or the fuel filter. When were these changed last? The fuel filter can be slightly plugged and when the engine needs fuel the filter cannot supply if fast enough. Just a thought.

When selecting a dealership to diagnose and fix a cummins make sure they at the least sell them there. Then ask if they have a certified cummins mechanic.
I have unfortunately had experience with dodge minivan mechanic trying to diagnose my injector harness... It doesnt work out.

If you're not under warranty i would find a reputable diesel shop with some performance experience as well. The ones with the knowledge of what these trucks are capable of tend to be more experienced.

I would start with looking at fuel supply. A set of gauges help us and you.
Fuel psi? Fuel lift pump
Is your muffler or silencer plugged? Excessive heat, look for discoloration on the muffler in a certain spot. This will block the exhaust causing gasses to back up and choke the engine.
A few common things to look for.
Someone with a good scan tool could drive your truck and monitor things while driving like fuel psi.
Hope this helps a lil'

It would help us a lot if you would post what the codes are. IF they are not giving you the codes, then tell them too.
You can also, turn the key, On, Off, On, Off, On.....start from the off position, not the lock position. and you can get the codes from the Odometer. Be ready with a pen and paper to write them down. Then post them up here. We can help much better then. ")

Also,,, Do you have any deletes? if not, I recommend it.

Hummm what ever the position is that is right next to the on position. My accessory position is counter clockwise one click from lock. So that would not work on mine.

Yeah I think the non-EVIC trucks w/ the LCD/LED green digit odometer are all ACC-OFF-ON-START -- newer vehices with the EVIC and WIN are OFF-ACC-ON-START....so older it was always OFF-ON cycling, with the newer it'll be ACC-ON.

Haven't met a Chrysler product yet w/ OBD that one variation or the other doesn't work on.

Just got the call from the Dealer that the code was Turbo performance, actuators gummed up. Seems to me they could have diagnosed that one before the truck did. apparently it finally got bad enough to trip a sensor, have not drove it yet to see how it runs, will let yall know. Thanks For All the Help!

They don't do any diagnostics anymore. Most so called "mechanics" - especially at dealerships - can't do anything without step by step directions. There are a fair amount of old school good ones out there but few and far between. Nowadays if it doesn't throw a code they assume it must be fine.

Not necessarily, had my turbo replaced under warranty and did full deletes about 5k miles afterwards. Drove the truck fine for about the same miles and now I've had p2262 for a couple thousand miles. I know being a grocery getter dosen't help but it does get ran on the highway regularly. I do know the deletes are better though, not disputing that there just not a 100% solution though.

Kinda following this topic. I have a 6.7L just out of warranty and its still bone stock. Does anyone know if chrysler will honor a turbo replacement out of warranty because they know it's from the DPF and EGR system? Just curious if anyone has tried that.

Highly doubt they will. They outline the terms of the warranty and once those terms are expired it's on you.

I see no way they would do that.

ok. I need to research that lawsuit and follow it. I figured chrysler would have just replaced the turbo's out of warranty before letting it go to court.

I wish you the best of luck.
BTW, I never had any problem with my turbo at all. Then I spent 4 months in Denver. Only drove a block to work and back, and withing a month I had a sticky turbo that was throwing a CEL. I got a new one under warranty due to my low mileage. I believe the new turbos are upgraded. Redesigned the turbine housing. I did notice a difference,,,, or maybe it was just that my turbo was working properly again. LOL
