Generic OBD II code -- throttle position error. Check the connector on the big plastic ring around the intake that drives the throttle body module. If that's night and tight ... wait and see if it goes away. If it doesn't and there are no other symptoms, maybe you jiggled a wire. If it doesn't and there are other symptoms, then maybe the throttle module is bad.
