Obd Code P0037 01 Toyota Spyder Need Help

I have a 2001 Toy Mr2 Spyder and have a code showing up P0037. Could anyone help me with some info on how to fix/ where I need to be looking on the car for the part to replace to clear this code.
thanks for your help in advance!!!

I hate to say this but i dont know how. But i was wondering if you guys in USA can buy any year of car from Japan? cause we can't import anything here until its 15 years is the general rule in Canada. oh and sorry for leaving a reply and no answer :banghead:
