If the oil temp sensor is unplugged, the indicated temp should be around -40C / -40F.

The ecu may have problems then. 😕
I'll check that next. Ughhhhhhh

That's possible... when wires melt and short out bad things can happen

I will have a look at the oil temp gauge wiring diagram and see if anythings stands out.

If you have an OBD scanner and smart phone/tablet there are ways to check the oil temp using apps like Torque Pro or OBD Fusion (with the $15 enhanced diagnostic add on)

This way we can verify the exact oil temp the ECU is seeing.

If you have an Android device, here is how you can configure the Torque Pro (~$5) app to display engine oil temp for free:
