I-P0178 Fuel Composition Sensor Circuit Low Inpuit

Ikhodi yomkhiqizi i-P0178 ayijwayelekile kakhulu. Uma ikhompuyutha yemoto ibonisa ubukhona noma umlando wokuba khona kwamanzi kuphethiloli, lesi sixwayiso sisho ukuthi uphethiloli ungase ungcoliswe izithasiselo zikaphethiloli.

Qaphela: Kubalulekile ukugwema ukukhanya kwenjini yokuhlola kuphaneli yensimbi engena ngenkathi ushayela. Uma lokhu kwenzeka, ungakhathazeki - sizokukhombisa ukuthi ungayilungisa kanjani ikhodi ye-P0178 futhi wenze imoto yakho ibuyele endleleni.

Incazelo Yezobuchwepheshe Yekhodi Yenkinga ye-OBD-II - P0178

Okokufaka Okuphansi Kwesenzwa Yokwakheka Kwamafutha

Isho ukuthini ikhodi P0178?

Lawa makhodi ephutha athile akhombisa inkinga ngenzwa yesekethe exhunywe kusistimu eqapha ikhwalithi nokwakheka kukaphethiloli. Ngokujwayelekile lawa makhodi avela ezimotweni ezisebenzisa uphethiloli oguqukayo. Ikhodi ye-P0178 ikhombisa isignali ephansi yokufaka noma inkinga yokwakheka kukaphethiloli, njengamazinga e-ethanol edlula izinga elamukelekayo. Ikhodi P0179, ngakolunye uhlangothi, ikhombisa isignali ephezulu yokufaka. Womabili amakhodi akhombisa ukwakheka kukaphethiloli okungavamile noma ukuhlola okungalungile nzwa.

Izinzwa zokwakheka kwamafutha azizona izinto ezisetshenziswayo ezijwayelekile kuzo zonke izimoto, kodwa zisetshenziswa kuphela kulezo ezikwazi ukuguquguquka. Uma injini yakho iphonsa ikhodi engu-P0178, kusho ukuthi inzwa ayithumeli idatha noma idlulisela idatha ngaphandle kwemikhawulo evamile. Kulokhu, injini isebenzisa imingcele ejwayelekile futhi ayikwazi ukushintsha kahle phakathi kwephethiloli evamile ne-flex.

Yiziphi izimpawu zekhodi ye-P0178?

Uphethiloli owusebenzisayo njengamanje udlala indima enkulu ezimpawini ezihlobene nekhodi yemoto yakho engu-P0178. Ngokuvamile, uma le khodi yenziwe yasebenza, ngeke ukwazi ukusebenzisa uphethiloli oguqukayo ngenxa yokuthi Imojula Yokulawula Injini (ECM) izonamathela kuzilungiselelo ezijwayelekile.

Nokho, ngisho noma imoto yakho ingaklanyelwe uphethiloli oguquguqukayo, ngokuvamile injini ingabhekana nalesi simo. Ngenxa yalokho, ungase ubone ukulahlekelwa amandla enjini, ubunzima bokuqalisa, kanye nokwenyuka kokusetshenziswa kukaphethiloli. Ngezinye izikhathi, nakuba kungavamile, kungase kungenzeki nhlobo ukuqala imoto.

Uma imoto yakho inekhodi engu-P0178, ungase ube nalezi zimpawu ezilandelayo:

1. Ukusebenza kwenjini okwehlisiwe.
2. Ubunzima noma ukuntuleka kokuqala.
3. Imayela elincishisiwe ethangini elilodwa.
4. Ukwanda kokusetshenziswa kukaphethiloli.
5. Isibani senjini yokuhlola siyakhanya.
6. Injini ingase ima.

Yiziphi izimbangela ezingenzeka zekhodi ye-P0178?

Ikhodi ye-P0178 ivame ukuhlotshaniswa nenzwa yokwakheka kukaphethiloli engalungile, kodwa ezinye izinkinga zingase zenzeke.

Uma isignali yokufaka inzwa ingekho ezingeni, imojula yokulawula injini (ECM) ithola okuvuliwe kusekethe yenzwa. Ngokufanayo, uma i-wiring noma uxhumano kwinzwa kuphazamisa ukuqhubeka kwesifunda ngenxa yokuxhuma okuxekethile noma izintambo eziphukile, i-ECM inquma ukuthi isifunda sivuliwe.

Ikhodi ibonisa ukuthi ukufundwa akufinyeleli ku-ECM noma kungaphandle kwemikhawulo evumelekile. Ngisho noma inzwa isebenza kahle, inkinga yezintambo ingase ibangele ukuthi ukufundwa kungafinyeleli ku-ECM, okubangela ukusetha ikhodi.

Okokugcina, kungase kube nezinkinga ezingandile ngemojula yokuphatha amandla (PCM). Nokho, ngokuvamile kudingeka isibuyekezo ukuze kuxazululwe.

Akuvamile ukuthi isibani senjini yokuhlola sivuleke ngenxa yezinkinga ze-PCM njengoba lawa mamojula ngokuvamile ethembeke kakhulu.

Ikhodi ye-P0178 ingabonisa izinkinga ezihlukahlukene, kuhlanganise:

1. Ikepisi yethangi likaphethiloli enephutha noma eyonakele.
2. Ukungcola kuphethiloli.
3. Ukuba khona kwamanzi kuphethiloli.
4. Isici noma ukulimala kwenzwa ngokwayo.
5. Ulayini kaphethiloli uvalekile noma ulimele.
6. Izinkinga zezintambo zesiyingi.
7. Ukungasebenzi kahle kwe-ECM.

Ibucayi kangakanani ikhodi ye-P0178?

Ama-DTC P0178 kanye ne-P0179 abucayi kakhulu futhi ngokuhamba kwesikhathi angaba nomthelela omkhulu ekuphepheni nasekushayeleni imoto yakho. Ubunzima benkinga buncike esimweni esithile. Isibonelo, ukuba khona kwamanzi kuphethiloli kunganciphisa ukusheshisa nokusebenza kwemoto iyonke, kwenze ukushayela emigwaqweni emikhulu nasezimweni ezinzima zethrafikhi kuphephe kancane.

Ngingakwazi ukuqhubeka nokushayela ngekhodi engu-P0178?

Yebo, ungakwazi ukushayela imoto ngekhodi ye-P0178 noma i-P0179 isikhathi esifushane, kodwa kuya ngokuya kuba yingozi njengoba inkinga iya iba yimbi. Ngakho-ke, kubalulekile ukuxilonga nokulungisa inkinga ngokushesha ngangokunokwenzeka ukuze uvimbele izinkinga zokuphepha nempilo engenzeka.

Umakhenikha Uyithola Kanjani Ikhodi Yenkinga P0178?

Qaphela: Isinyathelo sokuqala sokuxazulula izinkinga ukuthi ubheke amanqampunqampu obuchwepheshe aqondene nonyaka wemoto yakho, imodeli, kanye ne-powertrain. Kwezinye izimo, lokhu kungonga isikhathi esiningi ngokukukhomba endleleni efanele yokuxazulula inkinga. Izinyathelo ezibalulekile zifaka:

1. Ihlola isimo sekepisi yethangi likaphethiloli.
2. Ukuhlola isimo sikaphethiloli ukuze kube khona ukungcola.
3. Bheka ngokubonakalayo ukuxhuma kwesekethe nezintambo.
4. Ukuhlolwa okubonwayo kwesimo sezintambo zikaphethiloli ukuze kutholakale iziphambeko.
5. Ukuhlola ukwethembeka kanye nokungabikho kokugqwala ekuxhumekeni kukagesi.

Izinyathelo ezengeziwe ziyahlukahluka ngemodeli yemoto futhi zingadinga okokusebenza okukhethekile nedatha yobuchwepheshe. Ukuze wenze lezi zinqubo, uzodinga i-multimeter yedijithali nolwazi olufanele lobuchwepheshe mayelana nemoto yakho. Amandla kagesi azoncika onyakeni, imodeli kanye nohlobo lwenjini.

Isekhethi ihlolwa ngokucisha futhi kuxhunywe inzwa ne-ECM (imojula yokulawula injini). Ukuba khona kwamandla nomhlabathi kuhlolwa ngokuhambisana nedatha yezobuchwepheshe. Umhlaba kufanele uhlale ungu-0V futhi amandla ogesi kufanele ahlale engu-5 noma u-12V, kuye ngokucushwa kwesistimu. Imanuwali yobuchwepheshe ezinikele noma izinto eziyisethenjwa eziku-inthanethi zemoto yakho zizokusiza ukuthi uqedele lezi zinyathelo. Uma konke ukufundwa kulungile, ingxenye ehambisanayo cishe idinga ukushintshwa.

Yini okufanele ngiyigweme lapho ngibheka ikhodi engu-P0178?

Ukuze uvimbele ukuxilonga, landela lo mthetho olula:

Qiniseka ukuthi ukuxhumeka kunzwa kuvikelekile ngokuyihlola ngokuyibuka. Kwezinye izimo, ngemva kokusevisa isihlungi, ukuxhumana kungase kuxege futhi kungathembeki.

Kwezinye izimo, ukuhlolwa ngezikhathi ezithile kunconywa ukukhomba umthombo wephutha, ikakhulukazi uma kungekho mandla noma umhlabathi. Ukuhlola ukuqhubeka kwezintambo kufanele ngaso sonke isikhathi kwenziwe lapho amandla esekethe evaliwe futhi ukufundwa kokumelana okuvamile kufanele kube ngu-0 ohms ngaphandle kwalapho kushiwo ngenye indlela eshidini ledatha. Uma kutholwa ukumelana noma izintambo ezivulekile, lokhu kungase kubonise inkinga edinga ukulungiswa noma ukushintshwa.

Sithemba ukuthi lolu lwazi lusizile ukukukhomba endleleni efanele ukuze uxazulule inkinga yesekhethi yenzwa yokuqamba uphethiloli. Kubalulekile ukuqaphela ukuthi kufanele ngaso sonke isikhathi unamathele kudatha ethile yobuchwepheshe kanye namanqamu wesevisi wemoto yakho.

Izindleko zokulungisa inkinga P0178

Ikhodi P0178 ikhombisa “Inzwa Yokwakheka Kwamafutha Okokufaka Okuphansi Kwesekethe” njengekhodi Yenkinga Yokuxilonga (DTC). Lokhu kungabangelwa izici ezihlukahlukene. Ukuze uhlonze ngokunembile imbangela futhi usule ikhodi, kunconywa ukuthi uxhumane nomakhenikha wezimoto oqeqeshiwe.

Ngo-€120, umakhenikha wezimoto onolwazi uzoza ekhaya noma ehhovisi lakho futhi ahlole ukukhanya kwenjini yakho yesheke. Inkokhelo izokwenziwa ngemva kokuhlonza inkinga namasevisi anikezwayo.
