The sensor is right next to the heater hose outlet on the front passenger side of intake manifold. It is very small with an oval shaped connector going to it. I have the same engine.

I would first check to see if both heater hoses are hot to the heater.
if 1 is hot and 1 is cold the heater control valve is closed or the heater core is plugged.

it is possible that your coolent level is low or the thermostat that you just bought could be bad and one other thing there could be air in the system there for you gt to burp the system until the air is compleatly out

Check the gauge by holding in the trip odometer reset button and turn key to run,hold button for 10 seconds this will iniate a diagnostics on all the gauges,and lights if gauge doesn't move during this test replace gauge,if it does move then check the wires on the plug at the engine coolant temp sensor (ects) you can check the sensor by using a ohms meter by unpplugging it and check ohm's or resistance when cold and then start engine as the engine warms up the ohm's reading should gradually lower as the sensor is a thermister and as it warms up the resistance will drop.
