Thanks for posting your follow-up and, hopefully a solution.
The 2005+ fly-by-wire accelerator pedal actually has two sensors that track the position of the pedal, and two circuits going to the engine control module. The duplication is for safety -- both signals have to be within a fixed range (voltage) of each other. If they don't match, the ECM puts the engine into fail-safe mode.
The loose connector is a very strong possibility. It's also possible that in other cases, because the accelerator assembly is at floor level and could be exposed to water, salty solutions and dirt, the contacts themselves could get dirty or corroded, leading to bad connections which would also trigger the code.
Let us know if it does work out.
