Yep thats the sensor, have you looked to see if the Thermo needs replacing? Mine did this, replaced the thermo = problem fixed.

could the stat be stuck open

its on the front of the block, near the middle, will cost you about £13-16 for a new part and you can change it yourself with the correct tools, Id do it if I were you otherwise you have no idea if your car is over heating or not.

it wont cause any issues but you as already said, you wont konw if your car is over heating.

If it goes up one bar it should keep going in theory, check the wiring first, I have seen a few of these with temperamental wiring, I have had to plug / unplug some 4 or 5 times before they work
