P043E Umgodi wesethenjwa ophansi wokutholwa kokuvuza kwe-evaporator

Idatha ye-OBD-II DTC

Uhlelo lokutakula umusi we-Fuel diaphragm yokulawula ukugeleza okuphansi

Kusho ukuthini lokhu?

Le yikhodi yenkinga yokuxilonga ejwayelekile (i-DTC) esetshenziswa kakhulu ezimotweni ze-OBD-II ezinesistimu ye-EVAP esebenzisa uhlelo lokuthola ukuvuza. Lokhu kungafaka kodwa kungagcini kuToyota, Scion, GM, Chevrolet, Hyundai, Pontiac, Volvo, njll. Ngokweminye imibiko, le khodi ibonakala ijwayelekile kakhulu ezimotweni zakwaToyota. Yize kuvamile, izinyathelo eziqondile zokulungisa zingahluka ngokuya ngemodeli yonyaka, ukwakheka, imodeli, nokucushwa kokudluliswa.

I-PCM ithole ukungafani ku-diaphragm yokulawula i-EVAP lapho ikhodi ye-P043E igcinwa emotweni yakho ye-OBD-II. Kulokhu, kuboniswe isimo sokugeleza okuphansi.

Uhlelo lwe-EVAP lwenzelwe ukubamba umusi wephethiloli (kusuka ethangini likaphethiloli) ngaphambi kokuthi ludedelwe luye emoyeni. Isistimu ye-EVAP isebenzisa indawo yokugcina amanzi (evame ukubizwa ngokuthi i-canister) ukugcina umhwamuko ongaphezulu kuze kube yilapho injini isebenza ngaphansi kwezimo ezifanele ukuyishisa kahle.

Ingcindezi (eyenziwe ngokugcina uphethiloli) isebenza njenge-propellant, iphoqa umusi ukuba uphume ngamashubhu futhi ekugcineni ungene ebhokisini. Isici sekhabhoni esiku-canister sidonsa umusi kaphethiloli futhi siwubambe ukuze ukhishwe ngesikhathi esifanele.

Izimbobo zesampula ezahlukahlukene, ipompo ukuthola ukuvuza, ibhokisi lamalahle, igeji yengcindezi ye-EVAP, i-purge valve / solenoid, i-exhaust control valve / solenoid, kanye nohlelo oluyinkimbinkimbi lwamapayipi wensimbi namapayipi enjoloba (asuka ethangini likaphethiloli aye ethangeni engine bay) yizinto ezijwayelekile zohlelo lwe-EVAP.

I-vacuum yenjini isetshenziswa uhlelo lwe-EVAP ukudonsa umusi kaphethiloli (kusuka ethangini lamalahle kanye nasemigqeni) kungene ezininginingi zokudla, lapho kungashiswa khona kunokuba kuvulwe umoya. I-PCM ilawula ngombane i-purge valve / solenoid, okuyisango lesistimu ye-EVAP. Inesibopho sokulawula i-vacuum esekungenisweni kwebhokisi le-EVAP ukuze umhwamuko wephethiloli ukwazi ukudonswa kuphela enjinini lapho izimo zilungele ukushisa okusebenza kahle komoya womoya wephethiloli.

Ezinye izinhlelo ze-EVAP zisebenzisa ipompo yokuthola ukuvuza okucindezelekayo ukucindezela uhlelo ukuze uhlelo lubhekelwe ukuvuza / ukugeleza. Izimbobo zokubheka ukuvuza zingabekwa endaweni eyodwa noma amaphuzu amaningi kulo lonke uhlelo lwe-EVAP. Amachweba wesithenjwa sokuthola ukuvuza avame ukulingana ukuze ukugeleza kukalwe kahle lapho kusebenza ipompo yokuthola ukuvuza. I-PCM isebenzisa okokufaka okuvela kucindezelo lwe-EVAP nezinzwa zokugeleza ngokuhlangana ne-port port / ports ukuthola ukutholakala kokuvuza ukuthola ukuthi uhlelo lokuthola ukuvuza lusebenza kahle yini. I-EVAP Leak Detection Reference Port ingaba ithuluzi elincane lohlobo lokuhlunga noma imane nje ibe yisigaba somugqa we-EVAP esivimbela ukugeleza ukuze inzwa yengcindezi / yokugeleza kwe-EVAP ithole isampula elungile.

Uma i-PCM ithola isimo sokugeleza okuphansi nge-EVAP Leak Detection Reference Port, kuzogcinwa ikhodi engu-P043E bese kuthi i-Malfunction Indicator Lamp (MIL) ikhanye.

Buyini ubunzima bale DTC?

Amakhodi wokuthola okuvuza we-EVAP afana ne-P043E aqondene nohlelo lokulawula umusi kaphethiloli futhi akufanele abekwe njengabucayi.

Yiziphi ezinye zezimpawu zekhodi?

Izimpawu ze-DTC P043E zingahle zibe nomphumela wezimpawu ezincane noma ezingabonakali nhlobo. Ungabona ukunciphisa umnotho kaphethiloli namanye amakhodi wokuhlola wokuvuza we-EVAP.

Yiziphi ezinye zezimbangela ezivamile zekhodi?

Izizathu zale khodi yenjini engu-P043E zingafaka:

• Inzwa yengcindezi ye-EVAP engalungile
• Imbobo yokuthola ukuvuza kwe-EVAP yonakele noma ivalekile.
• Isici seCarbon (canister) sidabukile
• I-EVAP eqhekekile noma echotshoziwe noma ulayini wokuhlanza
• Ukungena komoya okunephutha noma ukuhlanza i-solenoid
• Ipompo lokuthola ukuvuza elinamaphutha

Yiziphi ezinye zezinyathelo zokuxazulula inkinga i-P043E?

Iskena sokuxilonga, i-digital volt / ohmmeter (i-DVOM) nomthombo othembekile wolwazi lwemoto kuzobonakala kubalulekile ukuthola ikhodi ye-P043E.

Sebenzisa umthombo wolwazi lwemoto yakho ukuhlola ama-bulletins ezinsizakalo zobuchwepheshe (ama-TSBs) afana nezimpawu namakhodi avezwe emotweni etholakele. Uma ungathola i-TSB efanelekile, izokuqondisa ngqo kumthombo wenkinga ngaphandle kokuchitha isikhathi esiningi nomzamo.

Uma amanye amakhodi wesistimu e-EVAP akhona, hlonza futhi ulungise ngaphambi kokuzama ukuthola i-P043E. I-P043E ingahle ibe ukuphendula ezimeni ezibangele amanye amakhodi we-EVAP.

Ngaphambi kokungcolisa izandla zakho, xhuma isithwebuli esikhumulweni semoto sokuxilonga uphinde ubuyise wonke amakhodi agciniwe bese uqandisa idatha yozimele. Ngithanda ukubhala lolu lwazi phansi ngoba lungasiza njengoba ukuxilongwa kwami ​​kuqhubeka. Uma usukwenzile lokhu, sula amakhodi bese uhlola ukushayela imoto ukuqinisekisa ukuthi ikhodi isuliwe.

Okungcono, ungathanda ukuhlola ukushayela imoto kuze kube kwenzeka okukodwa kwezinto ezimbili; I-PCM ingena kumodi elungile noma ikhodi isuliwe. Uma i-PCM ingena kumodi ekulungele, unenkinga yesikhashana (noma uyilungise ngengozi) futhi akukho okuningi ongakwenza ngakho manje. Uma ebuya kamuva, isimo sokwehluleka kungenzeka ukuthi sibe sibi kakhulu futhi ungazama futhi. Uma i-P043E isethwe kabusha, uyazi ukuthi unenkinga enkulu futhi sekuyisikhathi sokuthi ungene ungene kuyo uyithole.

Qala ngokuhlola ngokubonakalayo yonke i-wiring yesistimu ye-EVAP nezixhumi ongakwazi ukufinyelela kuzo ngesikhathi esikahle. Ngokusobala, ngeke ususe noma yiziphi izinto ezinkulu ongazibuka, kepha gxilisa imizamo yakho ezindaweni ezinokushisa okuphezulu nasezindaweni lapho izintambo, izixhumi, izintambo zokuhlanza, kanye namapayipi e-steam kungaphazamisa izinto ezihambayo. Izimoto eziningi ziyalungiswa ngalesi sigaba senqubo yokuxilonga, ngakho-ke gxila bese wenza umzamo omncane.

Xhuma isithwebuli esikhumulweni semoto sokuxilonga bese ubona ukuhamba kwedatha. Idatha yokugeleza nokucindezela kwe-EVAP kufanele ihambisane nemininingwane yomkhiqizi lapho uhlelo lusebenza. Ezimweni eziningi, ukwenziwa kohlelo lwe-EVAP (purge solenoid valve kanye / noma futha yokuthola ukuvuza) kungenziwa kusetshenziswa isithwebuli. Ukuhlolwa kwenzwa ethile ye-EVAP kuzodinga ukwenziwa ngohlelo olwenziwe lwasebenza.

Sebenzisa i-DVOM ukuhlola izinzwa ze-EVAP nama-solenoids ukuqhathanisa nokucaciswa komkhiqizi. Noma iziphi izinto ezihlobene ezingacacisiwe kufanele zishintshwe. Uma kungenzeka, finyelela i-EVAP port yokuthola ukuvuza ukuze uhlole amalahle. Uma kutholakala ukungcoliswa kwamalahle, sola ukuthi ibhokisana le-EVAP lonakalisiwe.

Ngaphambi kokuhlola amasekethe wesistimu nge-DVOM, nqamula bonke abalawuli abahambisanayo ukuvimbela umonakalo. Bheka amazinga afanele ukumelana nokuqhubeka phakathi kwezingxenye ze-EVAP ne-PCM ngazinye usebenzisa i-DVOM. Amaketanga angahlangabezani nezincazelo adinga ukulungiswa noma ukushintshwa.

• Ikepisi likaphethiloli elixegayo noma elingalungile ngeke ligcine ikhodi engu-P043E.
• Le khodi isebenza kuphela ezinhlelweni zezimoto ze-EVAP ezisebenzisa uhlelo lokuthola ukuvuza.

Izingxoxo ezihlobene ze-DTC

• 05 ICorolla P2419, P2402, P2401, P043F, P043ESanibonani nonke Lesi isikhathi sami sokuqala kuleso sithangami. Ngakho-ke kubukeka sengathi ngisenkingeni neCorolla yami.

Udinga usizo olwengeziwe ngekhodi le-P043E?

Uma usadinga usizo nge-DTC P043E, thumela umbuzo kumazwana angezansi kwalesi sihloko.

QAPHELA. Lolu lwazi lunikezwa ngenhloso yokwaziswa kuphela. Akuhloselwe ukuthi isetshenziswe njengesincomo sokulungisa futhi asinacala nganoma yisiphi isenzo osithathayo kunoma iyiphi imoto. Yonke imininingwane ekulesi siza ivikelwe yi-copyright.
