dalilai

Dalili mai yiwuwa na DTC P0042 na iya haɗawa da:

• Buɗe kewaye a cikin firikwensin oxygen ko buɗe wutar lantarki ko waya ta ƙasa zuwa bankin firikwensin oxygen 1, No. 3
• Ƙaƙƙarfan tsarin murƙushewar ƙasa na iya lalacewa ko karyewa.
• PCM / ECM ko na'urar firikwensin firikwensin iskar oxygen mara lahani

Matsaloli masu yuwu

Bincika wayoyin firikwensin oxygen don lalacewa ko wayoyi mara nauyi zuwa firikwensin.

Cire haɗin firikwensin oxygen kuma tare da mitar volt ohm mita (DVOM) wanda aka saita zuwa sikelin ohms, duba juriya na kewaye mai hita ta amfani da zanen wayoyi azaman abin tunani. Yakamata a sami wasu juriya a cikin da'irar hita a cikin firikwensin, tsayayyar wuce kima ko wuce ƙimar ƙima zai nuna buɗe a cikin ɓangaren mai zafi na kewaye, kuma dole ne a maye gurbin firikwensin oxygen.

Duba waya ta ƙasa a mai haɗawa kuma duba juriya tsakanin sananniyar ƙasa da mai haɗa firikwensin oxygen.

Duba waya mai ba da wutar lantarki a mai haɗawa tare da DVOM da aka saita zuwa madaidaicin ƙarfin lantarki tare da ingantaccen waya akan waya mai ba da wutar lantarki da waya mara kyau akan sananniyar ƙasa don tabbatar da cewa akwai iko ga firikwensin oxygen. Idan babu iko ga mai haɗawa yayin fara abin hawa na farko (farawar sanyi), ana iya samun matsala tare da da'irar samar da wutar lantarki ta iskar oxygen ko PCM da kanta.
