rt durango help please.

Here is the diagram from my 99 factory service manual. Don't know if it will help. Both sensors share a ground at the power train control module and the 5volt supply from the PCM. If the 01 is the same, I'd personally check for continuity from the sensors to the PCM ground and also the the 5 volt supply wiring from PCM to each sensor. AGAIN keep in mind this diagram is for a 99. It shouldn't be too hard to run down. As far as the vehicle goes I love my 99. Some of the issues I've dealt with have been brakes. The steel line going to the rear brakes let go right by the gas tank. I totally rebuilt the front end. The recent one at about 150000 miles was tranny. I have also replaced both front wheel hub/bearing assys. The issue with the trannys is that in park and neutral there is no fluid pumped to the overdrive. There are some good shift kits out there that remedy that. The other thing with the magnums is the silly engineers closed the bottom of the intake plenum with a steel plate. The gasket tends to work out and starts pulling oil from the lifter valley. Usually the fuel mileage gets real bad. Yes worse than it already is, and you get valve ping pretty bad at part throttle. This is easy to tell by opening the valve body butterflies and looking in with a light. If you see oil it's leaking more than likely. Keep with it you'll get it.
