There is no throttle position sensor on these vehicles. The accelerator pedal itself, uses what is called three "potentiometers", meaning three variable resistors. Two are always increasing voltage, while one is decreasing IN THE SAME PROPORTION as the accelerator is moved through its entire travel (from idle to WOT). If any of the voltages go "outside" of the range the PCM "wants to see", it goes into what's called an FMEM strategy to a "forced idle" only mode. To verify this would require use of a scan tool that can monitor your APP (accelerator pedal position) data.
