Default p0117 advice and help please

my car over heats at idle only (not under load, even hard load)

the needle climbs rather suddenly after idling a bit and will throw a CEL for p0117 - engine coolant temp sensor circuit low input. the cel went away on its own but with it idling the needle starts to climb again and im sure the cel would return if i let it get hot enough.

fans work, coolant level is fine, no burping/hissing/overflowing. car otherwise runs fine. coolant/oil doesnt look mixed (so far)

where is this coolant temp sensor located on an ej255? i think that is my next move. but idk where it is.

car is 2013 impreza wrx thank you
