In a cable-operated system, the Accelerator Pedal Position (APP) sensor is not involved in the process of adding additional fuel. This system primarily relies on the physical movement of the throttle pedal, the rotation of the throttle shaft, and the Throttle Position Sensor (TPS) sending a signal to the Powertrain Control Module (PCM) indicating the throttle plate's position. The APP sensor is typically used in drive-by-wire systems, not cable-operated systems.
