I am getting this code on my 07' Honda Pilot. It says Engine Coolant Temp Circuit Low Input. Is this the ECT sensor and where is that located on this engine?

Thanks,

Look where the upper radiator hose meets the block. That's the thermostat assembly and the ECT should be sticking out of it.

 

to add: check the wiring to that sensor ~ maybe a loose connection to that sensor can be the culprit/ clean/ reconnect/ clear the trouble code & see if the same code returns

you can also test the sensor itself while it's still screwed into your engine... ohm meter

resistance readings will be high when cold, then warm up the engine, unplug the wiring & see lower ohms afterwards
