Smog 테스트가 자꾸 o2 sensor not completed에서 실패합니다

CA 73.***.50.59

200 마일 뛰고 나서는: All mechanics/testers recommended this first lilne solution.
But i heard this method does not always fix the problem.

배터리 교체후 ecu 학습 매뉴얼: is in the Honda manual and also at the link above.
This is the exact solution for some problems.

I think you’d better meet 딜러/스모그 리페어샾/메카닉. All 3, 1 by 1.
