Hey guys, I thought this might be something you all should be aware of.
Sunday, I drove to work and noticed my truck was being a little sluggish in acceleration, but didnt think anything of it. When I went to lunch about 4 hours later, I had a CEL pop up. Drove home, and noticed a wistle comming from the engine compartment under accelteration. So, when I got home, I noticed something smelled like it was burning. Popped open the hood and, holy $%@&!, there was a little black smoke comming off the drivers side exhaust manifold.
The stinking DPFE sensor had melted on the REF side, all the way through the plastic housing, and was dripping plastic down onto the exhaust manifold. I took the sensor to for, and the tech there said that he's seen it before, but it's not all that common.

Just a heads up for you guys. If you pop a P1400 or a P1401 code on a CEL, check your sensor to make sure it hasnt fried like mine.
