난이도 & 준비물
증상
엔진 경고등(EML) 점등. 연료 트림 이상(fuel trim both banks) 관련 오류. 초기에는 신선한 연료와 고회전 주행으로 일시적 개선되었으나 재발생. 연비 저하(15.5mpg).
처리 내용
진공 누수 확인 - 실린더 헤드 뒤쪽의 손상된 그로밋 발견 및 교체. EML 초기화 및 적응값(adaptation) 리셋. MAF(VDO/Continental) 교체 - 순정품보다 1/4 가격. 모든 시스템 초기화 후 연비 개선(20mpg 이상, 최대 30mpg 달성) 및 주행감 향상. 원래 MAF가 열화 상태였던 것으로 판단되며 문제 해결 완료.
