PURPOSE: A circuit for detecting the trouble of a motor detecting sensor for a vehicle is provided to easily detect the breaking of a wire by improving the structure of the circuit. CONSTITUTION: A circuit for detecting the trouble of a motor detecting sensor is composed of a sensor(100) for detecting the rotary direction and rpm of a motor, an encoder(110) for supplying power to the sensor and outputting a signal of the sensor, and an inner ECU circuit(130) having a diode and first and second resistors. The diode and the first resistor are connected to an output terminal of the encoder. The second resistor is connected to the diode and the first resistor to output detected signal of the encoder.
