cold start air regulator thingy.
not a sensor.
basically, 12V heats up a wax element that expands and closes a valve. when cold the valve is open and it gives it more air = higher idle, and when warmed up it closes to not give more air.
I've never heard of one leaking, but you can replace it with one from a variety of sources... I think mine is from a FWD SR20DE of some kind. You could probably go to nissan and point it out and they'd find it. They're used on a ton of vehicles, several different models that are physically interchangeable but not part # interchangeable, probably have different amounts of air let through...
