p0115 water sensor circuit malfuction,help please

Hi, I'm having these problems:

Thermostat not working
Engine bay fans on constantly

Temperature gauge not working

I changed the coolant temp sensor, that made no difference so I purchased a new thermostat believing that perhaps the thermostat was the problem that also came with a new sensor, Still no change.
I have now managed to get a diagnostic on the car and the error is "Thermostat temp sensor circuit malfunction". It appears that the thermostat and sensor are not at fault but that the fault lies in the wires or connector from the car to the sensor. Does anybody know how to test the wires? I've got a multimeter but don't know how to use it to test for this problem. Thank you.
