ʻano hoʻohana

1.If ka electronically mana wahie injection engine lako me ka exhaust oxygen sensor hiki ole i ka hana, e like me unstable idle speed, nāwaliwali ka wikiwiki, hoʻonui wahie hoʻohana a excessive exhaust kinoea, aʻaʻohe hewa 'ē aʻe i ka wahie lako a me ka ignition mea, ia. Aia paha kekahi hewa i ka mea ʻike oxygen a me nā kaapuni pili.

2. ʻO ka ʻōnaehana uila uila o ka hapa nui o nā ʻenekini he hana nānā ponoʻī. Ke hāʻule ka mea ʻike oxygen a i ʻole nā ​​​​ʻāpana pili, e kākau ʻokoʻa ka kamepiula i ka ʻike hewa, a hiki i nā limahana mālama ke ʻike i ka pilikia ma ka heluhelu ʻana i ke code hewa me kahi decoder kūikawā. Akā pehea inā ʻaʻohe mea hana kūikawā? Eia kekahi mau ala e nānā wikiwiki ai i ka maikaʻi o ka mea ʻike oxygen.

3. Inā manaʻo ʻia ʻo ka hāʻule ʻole e like me ka paʻa ʻole o ka wikiwiki a i ʻole ka wikiwiki maikaʻi ʻole ke kumu o ka oxygen sensor, e wehe wale i ka mea hoʻohui o ka mea ʻike oxygen i ka wā e hoʻoponopono ai. Inā nalo ka hemahema o ka ʻenekini, ʻo ia hoʻi, ua pōʻino ka sensor oxygen a pono e hoʻololi ʻia. Inā mau ka hemahema o ka ʻenekini, e ʻimi i ke kumu mai nā wahi ʻē aʻe.

4.Using kiʻekiʻe impedance voltmeter hiki ke nānā i ka maikaʻi o ka oxygen sensor. E hoʻohui i ka voltmeter ma ke ʻano like ma ka hopena puka o ka mea ʻike oxygen. Ma lalo o nā kūlana maʻamau, pono e hoʻololi ka volta ma waena o 0-1V, a ʻo ka waiwai waena ma kahi o 500mV. Inā lōʻihi ka hoʻololi ʻole ʻana o ka volta hoʻopuka, hōʻike ia ua pōʻino ka sensor oxygen.

5. ʻO kaʻoiaʻiʻo, he mea paʻa loa ka meaʻike oxygen, a hiki ke hoʻohanaʻia no nā makahiki 3 aʻoi aʻe paha e like me ka lōʻihi o ka maikaʻi o ka wahie i ka maʻamau. ʻO ka pōʻino maʻamau o ka sensor oxygen ke kumu nui ʻia e ka nui o ke kepau i loko o ka wahie. Pono nā mea hoʻokele kaʻa i hoʻolako ʻia me nā mea catalytic ʻekolu ala e hoʻolohe i kēia.
