PURPOSE: A controlling method for an electronic throttle valve control system is provided to prevent an ignition-off phenomenon of an engine by compensating for an output of a throttle position sensor when contact resistance is generated in a throttle position sensor line. CONSTITUTION: Opening degrees of an accelerator pedal and a throttle valve are received as output voltage from an accelerator position sensor and a throttle position sensor(S100,S110). A target opening degree of the throttle valve is calculated by an ECU based on a voltage signal transmitted from the accelerator position sensor(S120). Then, it is determined whether or not an output voltage signal of the throttle position sensor exceeds a predetermined resistance value of the throttle position sensor(S130). If the output voltage signal of the throttle position sensor is below the predetermined resistance value of the throttle position sensor, a target opening degree signal is outputted(S140). If the output voltage signal of the throttle position sensor exceeds the predetermined resistance value of the throttle position sensor, a signal for correcting the target opening degree of the throttle valve is outputted(S150). Then, a throttle driving motor is controlled to control the throttle valve(S160). After receiving a real opening degree of the throttle valve(S170), the target opening degree of the throttle valve is compared with the real opening degree of the throttle valve(S180).
