Since there is no voltage applied with the ignition off, if the gauge is not dropping down all the way, it is the gauge that has failed.
Temperature sensors are frequent failures but they are not active when the car isn't powered up. They can be intermittant, high, low but with no power, the gauge itself should go to the minimum.

I had the same problem with my 2001 Pontiac Montana and the intake manifold gasket. This is a major problem with these 3.4L engines, if you are in the states I'm pretty sure there is a class action law suite against GM for this. I had my manifold gasket replaced and it was about $1000 CAD. You need to get your vehicle looked at right away as this could cause major engine damage, coolant will leak into the engine and soon enough you will be replacing that too. Good Luck

SOURCE: Temperature sensor problem?
There are 2 different circuit that control the cooling fans.
The engine controller turns the low speed fan circuit on to control temperature and turns on the high speed fan circuit if the engine and A/C is running.
It sounds like your low speed fan function is not working.
Find your fan 1 fuse located in the under hood fuse panel and make sure it is not blown. If OK go to next step.
Find your fan 1 relay located in the under hood fuse panel. Find another relay in the fuse panel that matches and swap the two. If the fan then works you know you have a bad relay.
If both are check good, let me know and we will go from there.
Below, I have attached the wiring diagram for your cooling system, hope it helps.
