What does (ETS Motor in a 2004 Hyundia XG350 Sedan stands for? on 2004 Hyundai XG350

My check engine light is constantly on. My car has been stalling and cutting off when stoped at a light or stop sign. I've been told that it has something to do with an ETS motor that is attached to the Throttel Body. I need to know what does ETS stands for.
