How can I tell whether this is a temperature sensor issue, a thermostat or a water pump? As am getting different videos where people did all 3, so hard to tell which is which.

This is a code for the sensor circuit being to high so id go ahead and change the sensor first and check all the wires leading to and from the sensor to make sure theyre tight clean and not melted or damaged best of luck ".

Yep, I agree with MECHTRIX, I would change the sensor and then clear the codes,

P0118 - Engine Coolant Temperature (ECT) Sensor Circuit High Input

Here is the sensor location which is right below the throttle body. Check out the images (below). Please let us know what happens.
