Default Codes P2127 and P2138

Hi everybody, while driving home yesterday my 2010 Grand Sport Manual suddenly threw a check engine light, flashed messages about the active handling and traction control system, and went into reduced power mode. I was not amused. I pulled over and plugged in my I-1000 to run the codes and got P2127 and 2138. The codes are described as follows:

P2127 - Accelerator Pedal Position (APP) Sensor 2 Circuit Low Voltage

P2138 - Accel Pedal Pos (APP) Sensor 1-2 Correlation.

I'm going to start tearing into the car tonight when I get home, and I was wondering if people had a good idea where to start. The car is bone stock, and I even loaded the stock tune back on in a failed attempt to fix the problem. From what I read it sounds like I should look for damaged/shorted wires around the throttle body and accelerator assembly. Does this sound right? Any help is much appreciated.
