Kusho ukuthini ukuthi u-P2249?

Le Khodi Yezinkinga Zokuxilonga (i-DTC) iyikhodi yokudlulisela ejwayelekile futhi isebenza ezimotweni eziningi ze-OBD-II (1996 nangaphezulu). Lokhu kungafaka, kepha kungagcini lapho, izimoto ezisuka kwaHonda, Ford, Mazda, VW, Mercedes-Benz, Audi, Hyundai, Acura, BMW, njll. Naphezu kwemvelo ejwayelekile, izigaba eziqondile zokulungiswa zingahluka kuye ngonyaka wokwenziwa. imikhiqizo, amamodeli nokuhanjiswa. ukumiswa.

Ikhodi egcinwe i-P2249 isho ukuthi imodyuli yokulawula i-powertrain (PCM) ithole i-voltage yesethenjwa ephansi yenzwa ephezulu ye-O2 ye-block block 1. Inzwa 2 ibhekisa kwinzwa engenhla futhi ibhlokhi XNUMX ibhekisa kwibhlokhi yenjini engenayo inombolo eyisilinda eyodwa.

Isilinganiso senjini nophethiloli womugqa ngamunye wenjini siqashwe yi-PCM sisebenzisa idatha kusuka kuzinzwa ezishisayo zokukhipha umoya-mpilo. Inzwa ngayinye yomoya-mpilo yakhiwa kusetshenziswa i-zirconia sensing element etholakala maphakathi nendlu yensimbi evulekile. Ama-electrode amancane (imvamisa i-platinum) anamathisela inzwa ezintanjeni kusixhumi se-oxygen sensor harness isixhumi futhi isixhumi sixhuma kunethiwekhi yesilawuli (i-CAN) exhuma i-oxygen sensor harness kusixhumi se-PCM.

Inzwa ngayinye ye-oksijini iyajijelwa (noma isontekile) kumbhobho wokukhipha. Ibekwe kahle ukuze into yokuzwa isondele enkabeni yepayipi. Lapho amagesi okukhipha imfucuza ashiya ikamelo lomlilo (ngokusebenzisa izinqwaba ze-exhaust) futhi adlule ohlelweni lokukhipha (kufaka phakathi abaguquli be-catalytic), badlula izinzwa zomoya-mpilo. Amagesi okukhipha angena enzwa ye-oksijini ngokusebenzisa imingcele yomoya eyakhiwe ngokukhethekile ezindlini zensimbi futhi azungeze into ezwayo. Umoya ozungezayo ojikelezayo udonswa ngaphakathi ngezimbobo zocingo ezindlini zenzwa, lapho zigcwalisa khona igumbi elincane maphakathi. Ngemuva kwalokho umoya (osegumbini elincane) uyashiswa. Lokhu kubangela ukuthi i-oxygen ions ikhiqize amandla, abonwa yi-PCM njengamandla kagesi.

Umehluko phakathi kwenani le-oksijeni ioni emoyeni ozungezile (odonswe ku-sensor ye-O2) kanye nenombolo yama-molecule e-oksijini ekuqothulweni kubangela ukuthi i-oksijeni engaphakathi kwenzwa ye-O2 ibhule ngokushesha okukhulu futhi ngezikhathi ezithile kusuka kungqimba lweplathinamu eyodwa kuye kolandelayo. ... Njengoba i-ioni yomoya-mpilo ehambayo phakathi kwezendlalelo ze-platinum, amandla okukhipha inzwa yomoya-mpilo ayashintsha. I-PCM ibona lezi zinguquko kumandla wokukhipha inzwa ye-oksijeni njengezinguquko ekugxileni kwe-oksijini kugesi wokukhipha. Imiphumela yamandla we-oksijeni izinzwa iphansi lapho i-oksijeni eningi ikhona ku-exhaust (isimo esinciphile) futhi iphakeme lapho i-oxygen encane ikhona ku-exhaust (state rich).

Uma i-PCM ithola inani eliphansi likagesi kumthamo wenkomba ye-oxygen sensor, ikhodi engu-P2249 izogcinwa futhi isibani sesikhombisi esingasebenzi kahle (MIL) singakhanyisa. Izimoto eziningi zizodinga imijikelezo eminingi yokushisa (ekuhlulekeni) ukuvula ilambu lesixwayiso.

Inzwa ye-oxygen ejwayelekile O2:

Buyini ubunzima bale DTC?

Amandla kagesi anganele kusekhethi yesithenjwa se-O2 angaholela ekwehleni komnotho kaphethiloli nasekunciphiseni ukusebenza kwenjini. I-P2249 kufanele ihlukaniswe njengebucayi futhi kufanele ilungiswe ngokushesha okukhulu.

Yiziphi ezinye zezimpawu zekhodi?

Izimpawu zekhodi yenkinga ye-P2249 zingafaka:

• Ukunciphisa ukusebenza kwephethiloli
• Inciphise amandla enjini
• Amakhodi Okugcwala Agciniwe noma Amakhodi Wokukhipha Ocebile / Acebile
• Isibani senjini yensiza sizokhanyisa kungekudala

Yiziphi ezinye zezimbangela ezivamile zekhodi?

Izizathu zale khodi zingabandakanya:

• I-O2 sensor fuse ishayiwe
• Inzwa / s oksijini enamaphutha
• Izintambo ezishisiwe, eziphukile, eziphukile noma ezinqanyuliwe kanye / noma izixhumi

Yiziphi ezinye zezinyathelo zokuxazulula inkinga nge-P2249?

Uzodinga isithwebuli sokuxilonga, i-digital volt / ohmmeter (i-DVOM), nomthombo wolwazi wemoto onokwethenjelwa ukuxilonga ngokunembile ikhodi ye-P2249.

Ungonga isikhathi ngokusesha ama-Technical Service Bulletins (ama-TSBs) akhiqiza kabusha ikhodi egciniwe, imoto (unyaka, ukwakheka, imodeli nenjini) nezimpawu ezitholakele. Lolu lwazi lungatholakala kumthombo wolwazi wemoto yakho. Uma uthola i-TSB efanele, ingasheshe ilungise inkinga yakho.

Ngemuva kokuxhuma isithwebuli esikhumulweni sokuxilonga imoto bese uthola wonke amakhodi agciniwe kanye nemininingwane yoqweqwe oluhambisanayo, bhala phansi imininingwane (uma kwenzeka ikhodi ivele ibe phakathi). Ngemuva kwalokho, sula amakhodi bese uhlola ukushayela imoto kuze kube kwenzeka okukodwa kwezinto ezimbili; ikhodi ibuyiselwe noma i-PCM ingena kumodi elungele.

Ikhodi ingaba nzima kakhulu ukuxilonga uma i-PCM ingena kumodi elungile ngalesi sikhathi ngoba ikhodi iphakathi. Isimo esiholele ekuphikeleleni kwe-P2249 singadinga ukuba sibi kakhulu ngaphambi kokuba kutholakale ukuxilongwa okunembile. Uma ikhodi ibuyisiwe, qhubeka nokuxilonga.

Ungathola ukubukwa kwesixhumi, izixhumi zokuxhuma, izindawo zezingxenye, imidwebo yezintambo, nemidwebo yokuvimba (okuhlobene nekhodi nemoto okukhulunywa ngayo) usebenzisa umthombo wolwazi wemoto yakho.

Hlola ngokubonakalayo izintambo nezixhumi ezihambisanayo. Lungisa noma buyisela izintambo ezisikiwe, ezishisiwe noma ezilimele.

Sebenzisa i-DVOM ukuhlola amandla we-sensor ye-O2 kuphini elifanele lesixhumi (eduze kwesenzwa). Uma kungekho voltage etholakalayo, hlola uhlelo lwamafusi. Shintsha amafyuzi aqhephukile noma anephutha uma kunesidingo.

Uma kutholakala i-voltage, hlola isekethe elifanele kusixhumi se-PCM. Uma kungatholakali ugesi, sola isekhethi evulekile phakathi kwenzwa okukhulunywa ngayo ne-PCM. Uma kutholakala ugesi lapho, sola i-PCM engalungile noma iphutha lokuhlela le-PCM.

Ukuhlola izinzwa ze-O2: Qala injini bese uyivumela ukuthi ifinyelele izinga lokushisa elijwayelekile lokusebenza. Vumela injini ingasebenzi (ngokungathathi hlangothi noma endaweni yokupaka). Ngesithwebuli esixhunywe echwebeni lokuxilonga imoto, bheka okokufaka kwe-oxygen sensor ekusakazweni kwedatha. Nciphisa ukusakazwa kwedatha yakho ukufaka idatha efanelekile yempendulo esheshayo.

Uma izinzwa zomoya-mpilo zisebenza ngokujwayelekile, amandla omoya onqenqemeni lwezinzwa zomoya-mpilo umfutho wokuguqula okuguqukayo azojikeleza ngokuqhubekayo kusuka ku-1 kuye ku-900 millivolts lapho i-PCM ingena kumodi evaliwe yeluphu. Izinzwa zangemva kwekati nazo zizohamba phakathi kuka-1 no-900 millivolts, kepha zizobekwa endaweni ethile futhi zihlale zizinzile ngokwengeziwe (uma kuqhathaniswa nezinzwa zangaphambi kwekati). Izinzwa ze-oksijini ezingasebenzi kahle kufanele zithathwe njengezinephutha uma injini isebenza kahle.

• I-fuse ye-O2 yesifutho esishaywayo akuyona imbangela yekhodi egciniwe ye-P2249, kepha impendulo kumjikelezo omfushane wesekethe.
