촉매고장 P0420의 O2센서파형, 꼭 촉매고장이 아닐 수 있다

Dec. 20, 2021, 1:05 p.m., Mon, KST. SunJoo Moon

스캔시 다운스트림산소센서 (O2) 가 사진처럼 냉간시 문제있는것 처럼 보이다가 정상온도에 오르면 지평선처럼 표시되면 촉매는 정상이다. 촉매 고장코드는 P0420 혹 P0430이다. 만약 정상온도에서, 아이들시 혹 일정속도에서 O2의 파형이 초반의 O2처럼 사인파형을 보일경우 촉매고장 가능성이 매우 높다.

  • I like cars, that simple. Especially I like Honda and Saab vehicles, and enjoy maintaining cars myself. Also, feel very pleased and happy when my contribution to a variety of motor vehicle clubs solves the issues.
