Check engine Light

[wukong]

I have a 2007 Ram 2500 with a 6.7 l Cummins engine. The code indicates a Exhaust Pressure Senser. I've tried cleaning the original and I'm now on the second replacement. Somehow, I suspect three sensers cannot be my problem. Anyone with a suggestion as to what else could be causing this warning?

Can you post up the code?
I'm no expert, but maybe the experts here can better help if they knew what code it was throwing.

Is the DPF getting full? That may cause back pressure, but I don't know much about them as mine fell off when the truck had less than 3,000 miles on the clock.
