Truck thinks it is in 4 Low (low range light stuck on)

[POWERSMOKIN]

So I dot hit tonight. Parked, someone ran into me.

Pulled it into 4 low and backed out from over him, and pulled out and everything looked fine. Now, the truck thinks its in 4 Low when in 2WD it will shift into OD at like 15MPH... Jiggled the wires, found nothing...

Any input?

hows it do with the sensor unplugged?

Well it seems to have fixed itself. So I wont get to try that. Im gonna get all the fluids changed when I get back (in a month) and pull the sensor out and see if it needs cleaning.

The switches do go bad. I did have to replace mine a couple years ago.

After I saw the exploded parts view, it looks pretty simple. The shift shaft just presses the switch down.. I haven't changed the t-case oil since i bought it, so i think its time for that.
But When i get time, ill be pulling the sensor out and seeing if it looks bad (corrosion, buildup, bent etc.)
