Accelerator Control System
WARNING: This page is about a different car, the 2002 GMC C3500 HD and 2002 Chevrolet C3500 HD. However, it is still accessible from the selected car via links, so may be relevant.
The accelerator control system is an electronically controlled throttle type with an accelerator pedal attached to an accelerator pedal position module (1). This module sends the signals to the PCM which then controls the fuel injection pump.
