I-P0443 Circuit Value Emission Control System Purge Valve Circuit

Ikhodi Yenkinga ye-OBD-II - P0443 - Ishidi Ledatha

Isekhethi ye-valve yokuhlanza yesistimu yokulawula umhwamuko kaphethiloli.

I-P0443 iyikhodi ejwayelekile ye-OBD-II ekhombisa ukuthi imojula yokulawula injini (ECM) ithole ukungasebenzi kahle kuvalvu yokulawula ukuhlanza noma umjikelezo wayo wokulawula. Lokhu kungase kubonise isifunda esivulekile noma esifushane ku-valve noma isekethe.

Isho ukuthini ikhodi yenkinga P0443?

Le Khodi Yezinkinga Zokuxilonga (i-DTC) yikhodi yokudlulisela ejwayelekile, okusho ukuthi isebenza ezimotweni ezihlomele i-OBD-II. Yize kuvamile emvelweni, izinyathelo ezithile zokulungisa zingahluka ngokuya ngohlobo lomkhiqizo / imodeli.

I-EVAP (uhlelo lokuthola kabusha umusi) ivumela amagesi okukhipha avela ethangini likaphethiloli ukuthi angene enjini ngomlilo kunokuba akhishelwe emoyeni. Impahla ye-purge valve solenoid inikeze amandla ebhethri ashintshiwe.

I-ECM isebenzisa i-valve ngokusebenzisa iluphu yomhlaba ngokuvula i-valve purge ngesikhathi esithile, ivumela la magesi ukuthi angene enjinini. I-ECM ibuye ihlole isekethe lomhlabathi ngamaphutha. Lapho i-purge solenoid ingasebenzi, i-ECM kufanele ibone amandla aphezulu womhlabathi. Lapho i-solenoid icushiwe, i-ECM kufanele ibone ukuthi i-voltage yomhlaba yehlisiwe isondele ku-zero. Uma i-ECM ingaziboni lezi voltages ezilindelekile noma ithola isekethe evulekile, le khodi izosetha.

Qaphela. Le DTC iyefana ne-P0444 ne-P0445.

Izimpawu ezingaba khona

Izimpawu ze-DTC P0443 zingamane zibe ilambu le-Malfunction Indicator (MIL). Kungahle kungabi nazinkinga ngokusingatha. Kepha inhlanganisela emuncu noma ukusebenza kwenjini enolaka kungenzeka futhi uma i-valve yokuhlanza ibambeke ivulekile. Noma kunjalo, lezi zimpawu zivame ukuhambisana namanye amakhodi we-EVAP. Esinye isibonakaliso kungaba ukunyuka kwengcindezi ethangini likaphethiloli njengomsindo "wokushaya ikhwela" lapho i-cap isuswa, okukhombisa ukuthi i-valve yokuhlanza ayisebenzi noma ibhajwe.

• Ukukhanya Kwenjini Yokuhlola kuzokhanya futhi ikhodi izogcinwa ku-ECM.
• Ungase uqaphele ukwehla kancane kokusetshenziswa kukaphethiloli uma uhlelo lokubuyisela umhwamuko lungasebenzi.

Izimbangela zephutha P0443

• I-ECM iyalele ukuthi i-valve yokulawula ukuhlanza ivuleke futhi ithole noma isifunda esivulekile esingaphelele noma esifushane kumjikelezo.
• Ikhodi ye-P0443 ingabangelwa isifunda esivulekile sangaphakathi ku-valve yokulawula ukuhlanza noma isixhumi esigqwalile esibangela ukuthi i-valve ilahlekelwe ukuthintana.
• Ikhodi ingasetha futhi uma i-wiring ku-valve yonakele phakathi kwe-ECM ne-valve yokuhlanza, okwenza isifunda esivulekile uma ucingo lunqunywa, noma isifunda esifushane uma ucingo lufinyezwa emhlabathini noma amandla.

Kufanele kube nenkinga yokulawula ukuhlanzwa ukuqala ikhodi ye-P0443. CHAINhhayi ngempela i-valve. Imvamisa ziyibhulokhi lapho kuhlanganiswa khona i-valve ne-solenoid. Noma ingaqukatha i-solenoid ehlukile enemigqa yokuphuma kwi-valve yokuhlanza. Noma kunjalo, kungaba noma yikuphi okulandelayo:

• Iphutha le-purge solenoid (isifunda esifushane sangaphakathi noma isekethe evulekile)
• Ukuhlikihla ihhanisi lezintambo noma ukuxubha enye into edala okufushane noma okuvulekile kusifunda sokulawula
• Isixhumi sigugile, siphukile, noma sifushane ngenxa yokungena kwamanzi
• Isifunda somshayeli ngaphakathi kwemodyuli yokulawula i-powertrain (PCM) sinesici

Izixazululo ezingenzeka

1. Usebenzisa ithuluzi lokuskena, yala i-solenoid yokuhlanza ukuze isebenze. Lalela noma uzwe ukuchofoza kwe-solenoid yokuhlanza. Kufanele ichofoze kanye, futhi kwamanye amamodeli ingase ichofoze futhi.
2. Uma kungekho ukuchofoza okwenzekayo lapho ithuluzi lokuskena lenziwa lasebenza, nqamula isixhumi futhi uhlole i-solenoid nesixhumi ukuze kubonakale umonakalo, amanzi, njll. Bese uhlola amandla ebhethri ocingweni lokuhola ngokhiye uvuliwe. Uma une-voltage yebhethri, gaya ngesandla iphaneli yokulawula nge-jumper wire futhi ubone ukuthi i-valve iyachofoza yini. Uma kunjalo, uyazi ukuthi i-solenoid isebenza kahle, kodwa kunenkinga ngesifunda sokulawula. Uma ingachofozi uma isisekelwe phansi, buyisela i-solenoid yokuhlanza.
3. Ukuze uhlole inkinga kusekethe yokulawula (uma i-solenoid isebenza ngokujwayelekile futhi une-voltage ku-solenoid), xhuma kabusha i-solenoid futhi unqamule intambo yesekethe yokulawula (ephansi) kusixhumi se-ECM (uma ungazi ukuthi ungakwenza kanjani lokho). yenza lokhu, ungazami). Njengoba intambo yaphansi inqanyuliwe ku-ECM, vula ukhiye bese ugaya mathupha intambo yokulawula i-valve yokuhlanza. I-solenoid kufanele ichofoze. Uma kunjalo, khona-ke uyazi ukuthi ayikho inkinga ngocingo lokulawula ku-solenoid futhi kunenkinga ngesekethe ye-ECM purge solenoid drive ku-ECM. Uzodinga i-ECM entsha. Kodwa-ke, uma ingachofozi, kufanele kube khona ukuvuleka kuzintambo phakathi kwe-ECM ne-solenoid. Kufanele uyithole futhi uyilungise.

Amanye ama-DTC wesistimu ye-EVAP: P0440 - P0441 - P0442 - P0444 - P0445 - P0446 - P0447 - P0448 - P0449 - P0452 - P0453 - P0455 - P0456

Umakhenikha uyihlonza kanjani ikhodi ye-P0443?

• Iskena amakhodi nekhodi yamadokhumenti ku-ECM, ibheka idatha yozimele ukuze ibone uma kwenzeka iphutha
• Ihlola zonke izintambo kanye nesistimu ye-valve yokuhlanza umhwamuko, okuhlanganisa nesixhumi sevalvu yokuhlanza ukuze igle, izixhumanisi ezilimele noma ezixegayo noma izintambo.
• Ihlola i-valve yokukhipha umoya yokuhlanza ukuthi ivaleke nokungcola, udoti, noma ubulembu.
• Yenza ukuhlola kokuvuza kwentuthu ohlelweni lomhwamuko kaphethiloli ukuze izame ukuthola imbangela yokuvuza komhwamuko kusetshenziswa imbobo yokuhlola umhwamuko.
• Ihlola i-valve yokulawula ukuhlanza ukuze ikwazi ukumelana ne-valve efanele bese ihlola ukusebenza kwe-valve isebenzisa i-ECM ukuze ilawule i-valve.

Amaphutha Avamile Lapho Uhlonza Ikhodi P0443

• Ungahloli futhi ucabange ukuthi i-valve yokulawula ukuhlanza inephutha ngaphandle kokuxilongwa okuphelele kwalo lonke uhlelo ukuze uthole kamuva ukuthi izintambo ziphukile noma zisikiwe.
• Ungaxazululi inkinga bese ushintsha izingxenye ezingaba inkinga noma zingabi yinkinga

Ibucayi kangakanani ikhodi ye-P0443?

• Ikhodi ye-P0443 ibangela ukuthi ukukhanya kwenjini yokuhlola kukhanye futhi lokhu kukodwa kuzoholela ekuhlolweni kwekhabhoni okuhlulekile.
• Le khodi isho ukuthi i-valve yokulawula ye-EVAP inesici noma isifunda kuyo ayixhunyiwe ku-valve, ngakho-ke i-ECM ilahlekelwe ukulawula kwe-valve.
• Uhlelo lokubuyisela umhwamuko nokusebenzisa kabusha, uma lungasebenzi kahle, lungaholela ekulahlekelweni kokusetshenziswa kukaphethiloli.

Yiziphi izilungiso ezingalungisa ikhodi P0443?

• Ukuhlola nokufaka esikhundleni se-valve yokulawula ukuhlanza
• Ukulungisa izintambo ezilimele ku-valve yokulawula i-blowdown nokuvimbela ukulimala kabusha
• Hlanza i-valve esikhundleni

Amazwana engeziwe okufanele acatshangelwe mayelana nekhodi P0443

Ikhodi P0443 iyikhodi evamile izimoto eziza nayo namuhla eyenza ukukhanya kwenjini yokuhlola kukhanye. Isizathu esivame kakhulu ukuthi ithangi likaphethiloli likhishwe ngephutha noma laxegiswa ngemva kokugcwalisa uphethiloli. Kule khodi, iphutha elivame kakhulu ukuthi i-valve yokulawula ukuhlanza inomjikelezo ovulekile wangaphakathi noma i-valve yokopha ayiwubambi umhwamuko.
