Same thing it is for every car.
IACV (Idle Air Control Valve). It's not a sensor, it's a valve that does whatever the PCM tells it to do, based on other sensors. Sounds like this is either unplugged or otherwise stuck/dirty, or you have a vacuum leak. Pretty much the only things that would cause this situation.
