Abstract

본 발명은 차량의 트로틀 위치 센서의 관한 것으로, 특히 트로틀 위치 센서의 단서 또는 단락 상태를 검출하여 흡입 공기량에 오류가 없도록 한 차량의 트로틀 위치 센서 이상 검출 확인 장치에 관한 것이다. 즉, 본 발명 트로틀 위치 센서에서 출력되는 전압의 단성과 단락에 대한 출력전압의 이상상태를 ECU에서 검출하도록하여 흡입 공기량 제어의 오류가 없도록 함으로써 차량 엔진 효율 및 주행 성능을 향상시킴을 목적으로 한다. 이에 따라, 트로틀 위치 센서의 단락 및 단선 상태를 쉽게 확인할 수 있게 됨으로써 잘못된 트로틀 밸브의 개도에 의해 엔진 효율이 저하되는 문제점이 방지되어 차량 성능 향상에 매우 효과적이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle's throttle position sensor, and more particularly, to an apparatus for detecting an abnormality in a vehicle throttle position sensor that detects a clue or short circuit condition of the throttle position sensor so that there is no error in the amount of intake air. That is, an object of the present invention is to improve vehicle engine efficiency and driving performance by allowing the ECU to detect an abnormal state of the output voltage for short and short circuits of the voltage output from the throttle position sensor. Accordingly, the short-circuit and disconnection state of the throttle position sensor can be easily checked, thereby preventing the problem of deterioration of the engine efficiency due to an incorrect opening of the throttle valve, thereby effectively improving the vehicle performance.
