You may have bad contacts on throttle sensor plug. Just take it apart by pulling yellow tab. Press slightly contacts so they have better grip. Put back together. Code should clear by its own over few days. You can check operation of throttle by removing air intake cover. Then recycle ignition to on and off. In off it does self calibration everytime you shut the engine off. If all OK you should see full throttle sweep. If it only moves slightly or shakes you still have wire problems.
