A throttle control system capable of ensuring and maintaining a minimum function of driving a motor vehicle by engine power with safety. A malfunction detection section detects a malfunction of at least one of first and second accelerator sensors and an accelerator switch on the basis of first and second accelerator operation amount signals and an accelerator switch output signal. A throttle opening control section forms a throttle control signal according to the first accelerator operation amount signal when the accelerator sensors are operating normally, and forms the throttle control signal on the basis of the accelerator output signal when a malfunction of the first or second accelerator sensor is detected.
