The project in my sig is done but still will not start. I have the factory TAC module, pedal assy and harness from the pedal to the TAC module as well as the factory 2005 PCM. My harness is the only thing that is not factory, and I believe there is a wire crossed that is giving me this APP code. The PCM thinks the throttle blade is at like 19 degrees, but it actually remains closed. The truck will start and run for about 3-10 seconds and then fall on it's face from dumping tons of fuel. If anyone has this diagram please help me here. This is my daily driver, and it is killing me not to have this thing running right now. Thanks in advance.
