I really can't tell. I haven't seen those hoses before, so my guess is that it's part of the California model. They might lead to the PAIR control valve (number 7 in schematic) or it's the breather hose??? This is from Page 6-12 in the service manual (see general topics section for service manual downloads).

 

that tube runs to the evaporative emission purge control valve

 

have a look in the tune up and routine maintenance chapter in manual
