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 power supplied to the motor is less then a value expected on the basis of the position and speed of movement derived from the output of a throttle position sensor.
