P2101 Ford - Escape

Question

My car was running and seemed to have no other problems but no acceleration or deacceleration. Took my car to a Ford dealership and Throttle body was replaced. Was called to pick up car and told I was having a code for accelerator pedal assembly but car was working fine. I was then called back and told car will not accelerate at all. Codes given were P0122A, P0223B, and P2101. Are these connected to or could they be caused by the Throttle Body malfunction? I had no problems or codes from my car prior to bringing it to the dealership for repairs. The throttle body was under a special warranty due to investigation of problems with the Ford Escape. Could this problem have been caused by this? Please help!!
