May 11, 2008 (10:39 am)
I am dealing with the same problem on my 2000 durango 4.7L . I followed some of the advice on the blog stream dealing with this- I had codes for up and down O2 right bank sensors and "right bank too lean" codes. I also had an obvious leak from the power steering relay switch into the wiring harness. I had dealer rewire with part #56045483AC harness bypass and replace up and down right bank O2 sensors and put in a new PS relay switch. As others have experienced I had 50% improved gas mileage (from 10 to 15 MPG). The check engine light also stayed off- for about 20 miles !!! then came back on again and the fuel mileage dropped. I hooked up the OBD and sure enough the codes for "upstream O2 sensor delayed response" and "Right Bank Too Lean" came up again. I will be taking it back to the dealer but would appreciate any other input that would lead to a long term fix. One thing I haven't had done is create the alternative ground discussed.

please see my message #497. sounds like you are in the same boat as the rest of us. I just had the right bank O2 sensors and PS (power steering) relay replaced, and a factory bypass harness installed to try and deal with the problem. The bypass harness is an after market fix Dodge developed to replace the PS fluid contaminated wires in the harness. After the repairs, I had good gas mileage for about 20 minutes after I drove the truck off the repair lot (Lithia Dodge in Klamath Fall OR), then the engine light came back on and the mileage dropped. When I pulled the plug off the PS relay I see PS fluid again. Either the new relay is leaking or the shop never replace the bypass harness and the fluid is coming from the old contaminated wiring. I am calling Lithia Dodge on monday to see what they replaced and to get this problem cleared up.There is hesitation problems associated with this as you mentioned. I notice it especially when at a constant speed or easing off the accelerator. I have read the entire message board from page 1. I count over 30 messages dealing just with this problem. There is also references to replacing the PCM because it can be fouled with PS fluid as well (Dodge will pay for due to this leakage defect). One of the key features that would put you in the same boat as the rest of us is poor gas mileage, diagnostic codes of right bank O2 sensor failures or delays, and black soot with smell of fuel on acceleration. The hesitation may be due to erratic and prolonged fuel injection pulses because of the faulty information the PCM gets from the failed O2 sensors.

My durango has the 5.9L engine in it and it has just recently overheated. I am looking to change the thermostat. Where is it?

Im also having this problem with my 05 Durango. Its not always consistant, but there will be a loud ratteling noise coming from with in the dashboard area. The funny thing, is that I also have an 05 Magnum and it has the same problem. Sounds like something is loose or got stuck from within the Glove Compartment and is now somewhere within the dash board. Any help or advice would be much appreciated. Not much of a mechanic... Thanks

Did this finally fix your problem. I have the same problem with my 2000 Drango, but not sure what to do. Did Dodge paid for any of the repairs.

In short no it did not. same symptoms and OBD readings. I suspect the wire harness bypass was not put in at the dealership as I had requested. Worse, I am getting the run-around when I ask details about the harness installation - if it was put in, what it bypassed, and connection points. I see no new work done to the main harness - no evidence of a bypass. I still have power steering fluid leakage from the wiring at the power steering relay and from the right bank O2 sensors. If the harness bypass been installed as requested, i doubt i should be seeing the PS fluid contamination at the O2 sensors. When I ask the repair tech if the harness bypass created a new ground for the upstream sensor I was only told "no, it was only an extension of the O2 sensor" indication it was not a bypass at all. I was told I had other problems that could cause the rich right bank fuel mix (the long and short term fuel trim on the right bank reads 30%) He wanted to do more work to investigate an exhaust manifold leak or maybe a computer problem. Until I am assured I have rerouted the ground to the right O2 sensors I will not submit to an expensive diagnostic into other issues. This problem is well documented. I firmly believe the primary problem is a faulty read from the O2 sensors to the computer caused by conduction problems in the wiring from power steering fluid. I may re-purchase the bypass harness at about 64 dollars just to see how it hooks up. It would be worth it rather than submit to the fleecing I can see the dealership is setting me up for. When i get the new bypass harness part, if I find out that in fact it was not installed or improperly installed- the dealership will be hearing from me.

I am having the same problem with my 06 Durango. We replaced the battery and the tire pressure and cargo lamp lights are on. How did you fix this problem?
