ABSTRACT:
An engine throttle control system comprises a control unit for controlling the position of a throttle by means of a motor in response to a position transducer actuated by an accelerator pedal. A detector detects when a signal produced by the control system is outside a range of acceptable values and, for instance, shuts down the engine. In one embodiment, the detector detects whether stress in an accelerator pedal return spring is less than a value expected.
