P0443 Dongosolo Lochotsera Kutulutsa Madzi Kutulutsa Dongosolo la Purge Valve Circuit

Khodi Yovuta ya OBD-II - P0443 - Kufotokozera Zaukadaulo

Purge valve yozungulira yamagetsi owongolera mpweya wamafuta.

P0443 ndi code generic OBD-II yosonyeza kuti gawo lowongolera injini (ECM) lazindikira kusagwira ntchito mu valve yowongolera purge kapena dera lake lowongolera. Izi zikhoza kusonyeza dera lotseguka kapena lalifupi mu valve kapena dera.

Kodi vuto la P0443 limatanthauza chiyani?

Izi Diagnostic Trouble Code (DTC) ndi njira yolozera, zomwe zikutanthauza kuti imagwira ntchito pamagalimoto okhala ndi OBD-II. Ngakhale zambiri, njira zina zakukonzanso zimatha kusiyanasiyana kutengera mtundu / mtundu.

The EVAP (vapor recovery system) imalola mpweya wotuluka mu tanki kuti ulowe mu injini kuti uyake m'malo mothamangitsidwa mumlengalenga. Purge valve solenoid imapereka magetsi osinthika a batri.

ECM imayang'anira valavu pogwiritsa ntchito chingwe cha pansi potsegula valavu ya purge panthawi inayake, kulola kuti mpweya uwu ulowe mu injini. ECM imayang'aniranso dera lapansi pa zolakwika. Pamene purge solenoid siinatsegulidwe, ECM iyenera kuwona mphamvu yapamwamba. Solenoid ikatsegulidwa, ECM iyenera kuwona kuti magetsi apansi atsitsidwa mpaka pafupi ndi zero. Ngati ECM sikuwona ma voltages omwe akuyembekezeka kapena awona dera lotseguka, code iyi idzakhazikitsidwa.

Zindikirani. DTC iyi ndi yofanana ndi P0444 ndi P0445.

Zizindikiro zake

Zizindikiro za DTC P0443 zitha kungokhala kuti Nyali Yosagwira Ntchito Yowunikira (MIL) yowunikira. Sipangakhale vuto lililonse posamalira. Koma kusakaniza kowonda kapena kugwira ntchito kwa injini kumakhala kotheka ngati valavu yoyeretsa yatsekedwa. Komabe, zizindikirozi nthawi zambiri zimatsagana ndi ma EVAP ena. Chizindikiro china chikhoza kuwonjezeka kuthamanga mu thanki ya gasi ngati phokoso la "mluzi" pamene kapu imachotsedwa, kusonyeza kuti valavu yoyeretsa sikugwira ntchito kapena yatsekedwa.

• Kuunikira kwa Check Engine kudzayatsidwa ndipo codeyo idzasungidwa mu ECM.
• Mutha kuwona kuchepa pang'ono kwamafuta ngati makina obwezeretsa nthunzi sakugwira ntchito.

Zifukwa za P0443 kodi

• ECM yalamula kuti valavu ya purge control itseguke ndipo yazindikira kuti dera lotseguka losakwanira kapena lalifupi pozungulira.
• Khodi ya P0443 ikhoza kuyambitsidwa ndi dera lotseguka mkati mwa valve yowongolera purge kapena cholumikizira chambiri chomwe chimapangitsa kuti valavu isagwirizane.
• Khodiyo imathanso kukhazikitsa ngati waya ku valavu akuwonongeka pakati pa ECM ndi valve yoyeretsa, kuchititsa dera lotseguka ngati waya wadulidwa, kapena chigawo chachifupi ngati waya wafupikitsidwa pansi kapena mphamvu.

Payenera kukhala vuto la purge control kuti muyambitse nambala ya P0443. CHENGAosati valavu. Nthawi zambiri amakhala chipika chomwe valavu ndi solenoid zimasonkhanitsidwa. Kapena ikhoza kukhala ndi solenoid yosiyana yokhala ndi mizere yotsekera ku valve yoyeretsa. Komabe, ikhoza kukhala iliyonse mwa izi:

• Defective purge solenoid (internal short circuit kapena open circuit)
• Kusisita chingwe cholumikizira kapena kupaka chigawo china ndikupangitsa kutseguka kapena kutseguka mumayendedwe owongolera
• Cholumikizira chatha, chosweka, kapena chachifupi chifukwa cha kulowa kwa madzi
• Dalaivala wozungulira mkati mwa powertrain control module (PCM) ndi yolakwika

Mayankho otheka

1. Pogwiritsa ntchito chida chojambulira, lamula purge solenoid kuti iyambitse. Mvetserani kapena mumve kudina kwa purge solenoid. Iyenera kudina kamodzi, ndipo pamitundu ina imatha kudinanso.
2. Ngati palibe kudina komwe kumachitika pamene chida chojambulira chatsegulidwa, chotsani cholumikizira ndikuyang'ana cholumikizira cha solenoid ndi cholumikizira kuti chiwonongeke, madzi, ndi zina zambiri. Ngati muli ndi mphamvu ya batri, tsitsani pamanja gulu lowongolera ndi waya wodumphira ndikuwona ngati valavu ikudina. Ngati ndi choncho, ndiye kuti mukudziwa kuti solenoid ikugwira ntchito bwino, koma pali vuto ndi dera lolamulira. Ngati sichikudina ikakhazikika pamanja, m'malo mwa purge solenoid.
3. Kuyesa vuto mu dera lowongolera (ngati solenoid ikuyenda bwino ndipo muli ndi voteji pa solenoid), gwirizanitsaninso solenoid ndikudula waya wowongolera (pansi) kuchokera ku cholumikizira cha ECM (ngati simukudziwa momwe mungachitire. chitani izi, osayesa). Ndi waya wapansi wochotsedwa ku ECM, yatsani kiyi ndikutsitsa pamanja waya wowongolera valavu. Solenoid iyenera kudina. Ngati ndi choncho, ndiye kuti mukudziwa kuti palibe vuto ndi waya wowongolera ku solenoid ndipo pali vuto ndi ECM purge solenoid drive circuit mu ECM. Mufunika ECM yatsopano. Komabe, ngati sichikudina, ndiye kuti payenera kukhala lotseguka mu waya pakati pa ECM ndi solenoid. Muyenera kuchipeza ndikuchikonza.

Ma DTC ena a EVAP System: P0440 - P0441 - P0442 - P0444 - P0445 - P0446 - P0447 - P0448 - P0449 - P0452 - P0453 - P0455 - P0456

Kodi makaniko amazindikira bwanji code ya P0443?

• Imasindikiza ma code ndi zikalata mu ECM, imayang'ana deta yowumitsa kuti muwone ngati cholakwika chachitika
• Kuyang'ana mawaya onse ndi makina a vapor purge valve, kuphatikiza cholumikizira valavu cha purge kuti chiwonongeke, chowonongeka kapena chotayirira kapena mawaya.
• Imayang'ana valve yotulutsa mpweya kuti itseke ndi dothi, zinyalala, kapena ulusi.
• Amayesa kutulutsa utsi pamtundu wa nthunzi wamafuta kuyesa kudziwa chomwe chayambitsa kutulutsa mpweya pogwiritsa ntchito doko loyang'anira nthunzi.
• Imayang'ana valavu yowongolera kuti igwire bwino valavu ndikuwunika ntchito ya valve pogwiritsa ntchito ECM kuwongolera valavu.

Zolakwa Zomwe Zimachitika Mukamazindikira Khodi P0443

• Musayang'ane ndikuganiza kuti valavu yoyeretsa ndi yolakwika popanda kufufuza bwinobwino dongosolo lonse kuti mudziwe ngati waya wathyoka kapena kudula.
• Osathetsa ndikusintha magawo omwe angakhale kapena osakhala vuto

Kodi P0443 ndi yowopsa bwanji?

• Khodi ya P0443 imapangitsa kuti kuwala kwa injini ya cheke kubwere ndipo izi zokha zipangitsa kuti kuyesa kwa mpweya kulephera.
• Khodi iyi imatanthawuza kuti valavu yolamulira ya EVAP ndi yolakwika kapena dera lake silinagwirizane ndi valve, kotero ECM yataya mphamvu ya valve.
• Dongosolo lobwezeretsa nthunzi ndikugwiritsanso ntchito, ngati silikuyenda bwino, limatha kuwononga mafuta.

Ndi kukonza kotani komwe kungakonze P0443?

• Kuyang'ana ndikusintha valavu yowongolera purge
• Kukonza mawaya owonongeka ku valve yowongolera ndi kupewa kuwonongekanso
• Purge valve m'malo

Ndemanga zowonjezera zomwe muyenera kuziganizira ponena za code P0443

Code P0443 ndi nambala yodziwika bwino yomwe magalimoto amabwera nayo masiku ano yomwe imapangitsa kuwala kwa injini ya cheke. Chomwe chimafala kwambiri ndikuti kapu ya tanki yamafuta idachotsedwa mwangozi kapena kumasulidwa itadzaza ndi mafuta. Pa code iyi, cholakwika chofala kwambiri ndikuti valavu yowongolera purge imakhala ndi dera lotseguka mkati kapena valavu yotuluka magazi ilibe nthunzi.

Mukufuna thandizo lina ndi nambala yanu ya p0443?

Ngati mukufunabe thandizo ndi DTC P0443, lembani funso mu ndemanga pansipa pamutuwu.

ZINDIKIRANI. Izi zimaperekedwa kuti zidziwitse zokha. Sikuti tizigwiritsa ntchito ngati malingaliro okonzanso ndipo sitili ndi udindo pazomwe mungachite pagalimoto iliyonse. Zomwe zili patsamba lino ndizotetezedwa ndi zovomerezeka.
