Automotive technology is increasingly developed by using electronic control, such as throttle by wire technology to improve conventional throttle system that has some disadvantages, which still using mechanical components, connected using sling cable, the pedal likely to jam or feel heavy because of dirt or crust, too many components, and complicated on maintenance. The research purpose is to make throttle by wire simulator without sling cable, more responsive in performance, easier maintenance, and can be teaching media. The simulator component consists a wire/cable, pedal sensor, minimum system, and servo motor as throttle driver. The experiment was conducted on simulators which designed and made. Research data were tested by correlation and regression test. The results showed that when the pedal stepped deeper, the output voltage of the pedal getting bigger, the throttle angle is balanced with the pedal movement, the greater angle of the throttle, the required current is greater. The speed response of the throttle towards the pedal is 0-0.11 seconds, so the simulator is very responsive and feasible to be used as a teaching aid.
