Oil Temp Gauge HELP!!

[Goose]

Ok I started getting the truck detailed for the Sept GTG and now my oil temp gauge is reading between 140 and 160 any input could I have bumped a wire or something? Where is the Temp Gauge sending unit?

Warm your truck and then bump or flick the gauge and see if it moves to the 200 range...after i removed mine and re-installed it, it has been sticking. i am going to replace mine. no idea on the sending unit though

mine started doing that,I would thump it and it would go up to 200,went to the dealership they said it was bad and replaced it.
