'09 2500 144" cargo
I have an 09 Dodge 2500 with 154k miles. I have had it for 2 years. For the most part, it has been running like a champ. I built it into a camper, have lived in it full time for a year and have been on a long road trip since early February. No recent service done except last December I had some rusted out transmission lines replaced at a dealership.
About 10 days ago I started experiencing loss of power on inclines. It first happened on a long slow incline where I would have normally been able to keep a steady 40-50 mph without much gas. On this day, I had the pedal to the floor and my mph were declining quickly, down to 20mph and I was struggling to keep it at that. The rpms were topping out at about 30. I heard a deeper sound from the engine on this day when hitting the gas pedal. I did not get any CEL during that drive. I stopped for a couple hours in the next city and when I started the van back up, my CEL was on. I ran a scan with my Autel AP200. At that point I only got one code: 9100 - KI-Instrument Cluster - Engine CAN bus - CAN fault. I decided to drive to my next destination before investigating further. I drove it a few hundred miles and the CEL stayed on through multiple stops and starts.
I scanned it again 3 days later while driving and received a new code: P2633. When researching P2633 I see that it is for Charge air system offset drift under load. In a previous thread Dennis listed possible causes for this code as intake air system leak, intake air temp sensor, maf air sensor or possible egr problem.
I continue to experience the same loss of power uphill, and the CEL remains on all the time. It may have improved a little, or I might have just gotten better at compensating for it. I can eventually get the van up to 60mph or higher, but it takes longer than usual especially going uphill. I have not heard the deeper engine sound again (not since that first day of experiencing the issue).
I checked my engine oil and transmission fluid level and they are both fine. I have read all the threads on this code, and all about the turbo seals, the air intake system seals / hoses, etc. The air intake tube from the air filter to the turbo has no cracks. The orange seal at the turbo seems intact and tight although I plan to replace it as a precaution. From my initial inspection, I noticed oil spray in two locations:
1. Photo 1. From the aluminum charge elbow to the resonator. Is this just an o-ring seal on this side? I think its this part that should be replaced.
2. Photo 2. On the hose leading to the intercooler on the passenger side. I believe it is this part. I can’t tell if this oil means the hose should be replaced or if it might be something else?
The 3rd and 4th photo are just to show the other side of the resonator, I don't think that is leaking but you can see some oil spray behind/under where the resonator is in these two photos.
If anyone can tell me what else to check / replace as a starting point I would be very grateful. I’d like to do any repairs myself if possible, and that will happen in a parking lot or national forest. I am a total beginner here and learning as we speak so any guidance would be greatly appreciated. Thank you!
I am also due for an oil / filter change, and fuel filter change so I will be doing that at the same time (this will be my 2nd time doing all that). I will also add BG245 to the tank after changing the fuel filter.
