Ok. I pulled the sensor and it looks clean. Of course that dont me squat.
I placed my finger in the hole and had my wife start it up for 2 seconds. It had enough pressure to blow oil past my finger.
So I have a replacement sensor on order, but I also want to test out the wires.
Does anyone have a diagram showing where the wires run and where they end up?
Just a quick, half-assed Google search, but I found this:

Not totally sure it applies to your Denali. But, pin #58, tan with white stripe. I'd guess that the low reference for it would be the one next to it (pin #57, black). I'm not certain, though.
