idle air control valve for 2001 maxima

anyone know exactly where idle air control valve is on a 2001 maxima. haynes book I have is for up thru 2001 but the pictures in it are for 2000 and back near as I can tell. It doesn't cover much for 2001 even though the front cover says it covers 2001. The PCM has a code set for this part and the book tells you how to check it if you can find it.
