458 water temp not displayed pump is hot!? Help!?

I have a 2013 458 spider. I noticed the temp guage doesn’t have a needle and I cannot tell what my cars temp is. I’m scared to drive it as I cannot tell if the cooling system is functioning at all. Please help.

Yes I know where the guage is on the left screen displayed next to the oil temp. The oil temp has a needle that starts at 120 and come up as the car gets warm. The needle doesn’t exist on the water temp!? Also the fan comes on right away when I start the car. And the red water temp light is flashing constant. I crawled under the car removed the skid plate and the part where the radiator hose comes off the motor is HOT!

 

Can that mean a fuse? I changed the sensor in the front under the trunk. Wires look good. Can barely get to the sensor above thermostat on motor from underneath but it is connected.
