OBD P0223

What can cause this?
Why can't I erase the code?
I have already replaced the throttle body.

After you replaced the throttle body, did you perform the "throttle valve closed position relearn procedure" and then the "idle air volume relearning procedure?" If not, you need to do that. If that still doesn't work, then it may not be the throttle body that is faulty. It could be a faulty accelerator pedal position sensor or a circuit issue. You can get a download of the engine control chapter of the factory service manual for you vehicle at NissanHelp.com; it'll have the diagnostic testing procedures as well as the relearn procedures in it:
