how do you relearn throttle control po2106 will not clear with generic scan tool

HOW MUCH HAVE YOU DRIVEN IT SINCE THE REPAIR,YOU MAY HAVE TO DRIVE FOR ABOUT 20 MINS TO GET THE SENSORS TO RECALIBRATE. THIS HAPPENS ON MOST MODELS. THEY MIGHT HAVE DISCONNECTED BATTERY AND NOT KEPT THE MEMORY ALIVE WITH THE PROPER TOOL.
