I-P245D High bypass control circuit ye-EGR epholile

Idatha ye-OBD-II DTC

Exhaust negesi Ukubuyiswa Cooler Dula Isifunda High

Kusho ukuthini lokhu?

Le yiGeneric Powertrain Diagnostic Trouble Code (DTC) esebenza ezimotweni eziningi ze-OBD-II (1996 nezintsha). Lokhu kungafaka, kodwa kungagcini lapho, iFord, iDodge, iRam, iJeep, iChevrolet, iVolkswagen, iMercedes, njll. Naphezu kohlobo olujwayelekile, izinyathelo zokulungisa ngqo zingahluka ngokuya ngomnyaka wemodeli, ukwakheka, imodeli nokudluliswa kokuhanjiswa. ...

Ikhodi yenkinga ye-OBD-II engu-P245D namakhodi ahambisanayo i-P245A, i-P245B, ne-P245C ahlotshaniswa nesekethe yokulawula ukudlula epholile ye-EGR.

Inhloso yesekethe yokulawula ukudlula epholile ye-EGR ukuvula nokuvala i-valve yokudlula ye-EGR ngaphansi kwezimo ezinqunyiwe ukuvimbela ukulayisha ngokweqile kwe-EGR, okwaziwa njengokuxhuma, okuthinta ukusebenza nokusebenza kahle kwenjini kadizili. Imodyuli yokulawula injini (ECM) ihlola lesi sifunda ngokuthola izingqinamba ezivela kusishintshi sokushisa se-EGR nezinye izinto ezihambisanayo ukulawula i-EGR cooler bypass valve, ebuyisela amagesi okukhipha ekufakeni amandla omlilo kokulungiselelwa okuningi. Indawo ye-EGR valve, i-EGR cooler, switch switch kanye nezinto ezihambisanayo kuyehluka kuye ngemoto kuye emotweni futhi kuyehluka kakhulu kusuka kumkhiqizi kuye kumkhiqizi.

Lapho i-ECM ithola ukuthi i-voltage noma ukumelana kuphakame kakhulu ngaphezu kwebanga elijwayelekile lamanani alindelwe ku-EGR cooler bypass control circuit, i-P245D izosetha futhi ukukhanya kwenjini yokuhlola, ukukhanya kwensizakalo ye-injini, noma zombili zingakhanyisa.

Okujwayelekile I-EGR Cooler Bypass Valve:

Buyini ubunzima bale DTC?

Ubukhali bale khodi bungahluka kakhulu ukusuka kokulingene kuya kokubi, ngokuya ngezimpawu ezithile zenkinga nezinga le-chiller nokudlula kwe-valve ukusebenza. I-valve engasebenzi kahle ye-EGR noma isekethe yokulawula kungadala ukuthungela ngokweqile nokushisa kwangaphambili kwenjini, okungalimaza ama-piston, ama-valve, nezinye izinto ezihambisana nenjini yangaphakathi.

Yiziphi ezinye zezimpawu zekhodi?

Izimpawu zekhodi yenkinga ye-P245D zingafaka:

• Injini Ingase Ihluleke Ukuhlolwa Kokukhishwa
• Ukukhala kukhalela noma kungqongqoza ngesikhathi sokushesha
• Ukwanda kokusetshenziswa kukaphethiloli
• Ukusebenza kabi kwenjini
• Ukukhanya kwenjini yensiza kuzokhanya kungekudala
• Isibani senjini yokuhlola sivuliwe

Yiziphi ezinye zezimbangela ezivamile zekhodi?

Izizathu zale khodi ye-P245D zingafaka:

• Exhaust igesi ukuphindaphinda okupholile kwe-valve kungasebenzi
• Okupholile okuvalekile noma okonakele kwegesi ekhipha kabusha umoya opholile
• Ukungasebenzi kahle kwethempelesha
• Ukwakhiwa kwe-carbon ngokweqile
• Izintambo ezingalungile noma ezilimele
• Isixhumi esonakalisiwe noma esonakele
• I-ECM enamaphutha

Yiziphi ezinye zezinyathelo zokuxazulula inkinga i-P245D?

Isinyathelo sokuqala sokuxazulula inkinga noma iyiphi inkinga ukubuyekeza i-Technical Service Bulletins (TSBs) yemoto ethile ngonyaka, imodeli nokutshala amandla. Kwezinye izimo, lokhu kungakongela isikhathi esiningi ngokuhamba kwesikhathi ngokukukhomba endaweni efanele.

Isinyathelo sesibili ukuthola zonke izingxenye ezihlotshaniswa nesekethe ye-EGR epholile futhi uzihlole ngomonakalo osobala obonakalayo. Kuye ngemoto ethile, le sekhethi ingase ihlanganise izingxenye ezimbalwa, okuhlanganisa ukushintsha kwezinga lokushisa, i-valve yokudlula, i-valve ye-EGR, i-EGR cooler, kanye neyunithi yokulawula injini. Yenza ukuhlola okujulile kokubuka ukuze uhlole izintambo ezihambisanayo ukuze uthole ukukhubazeka okusobala njengokuklwebheka, imihuzuko, izintambo eziveziwe, noma izimpawu zokusha. Okulandelayo, hlola izixhumi nezixhumi ukuze uthole ukuphepha, ukugqwala kanye nokulimala koxhumana nabo. Le nqubo kufanele ifake konke ukuxhunywa kwezintambo kuzo zonke izingxenye, okuhlanganisa ukushintshwa kwezinga lokushisa kwe-EGR neyunithi yokulawula injini. Bheka ishidi ledatha yemoto ethile ukuze uhlole ukumiswa kwesekethe yokulawula ivalvu ye-bypass ye-EGR futhi uqinisekise ingxenye ngayinye efakwe kusekethe, engahlanganisa i-fuse noma isixhumanisi se-fusible kwezinye izinhlelo zokusebenza.

Izinyathelo ezithuthukile

Izinyathelo ezengeziwe ziqondiswa kakhulu yimoto futhi zidinga ukuthi imishini efanelekile ukuthi yenziwe ngokunembile. Lezi zinqubo zidinga imultimeter yedijithali kanye nemibhalo eqondene nezobuchwepheshe eqondene nemoto.

Ukuhlolwa kwe-Voltage

Amandla wereferensi kanye nobubanzi obuvumelekile bungahluka ngokuya ngemoto ethile nokumiswa kwesekethe. Imininingwane ethile yezobuchwepheshe izobandakanya amatafula wokuxazulula inkinga nokulandelana okufanele kwezinyathelo ukukusiza wenze ukuxilongwa okunembile.

Uma le nqubo ithola ukuthi umthombo wamandla noma umhlaba ulahlekile, ukuhlolwa kokuqhubeka kungadingeka ukuhlola ubuqotho bezintambo, izixhumi, nezinye izinto. Ukuhlolwa kokuqhubeka kufanele kwenziwe njalo ngamandla angaxhunywanga kusekethe kanye nokuxhunywa kwentambo okujwayelekile nokufundwa kokuxhumeka kufanele kube ngama-0 ohms wokumelana. Ukumelana noma ukungabikho okuqhubekayo kubonisa iphutha lokuxhumeka elivulekile, elifushane, noma elonakalisiwe futhi elidinga ukulungiswa noma ukushintshwa.

Yiziphi izindlela ezijwayelekile zokulungisa le khodi?

• Ukufaka esikhundleni sokupholisa kabusha kwegesi yokukhipha igesi
• Ukufaka esikhundleni se-valve epholile ye-EGR
• Kumiselela iswishi lokushisa
• Ukuhlanza izixhumi kusuka ku-corrosion
• Lungisa noma buyisela izintambo ezingalungile
• Ukuhlanza ama-carbon deposits
• Ukukhanya noma ukufaka esikhundleni i-ECM

Iphutha elijwayelekile

• Ukufaka esikhundleni se-valve epholile ye-EGR lapho i-carbon build-up noma i-wiring engalungile idala i-ECM ukuthi isethe le khodi.

Ngethemba ukuthi ulwazi olukule ndatshana lusizile ukukukhomba endaweni efanele ukuxazulula inkinga ye-EGR epholile yokulawula isifunda se-DTC. Le ndatshana yenzelwe ulwazi kuphela futhi imininingwane ethile yezobuchwepheshe kanye namabhulethini wensizakalo yemoto yakho kufanele kuhlale kuqala.
