Reductant purge control vharuvhu yakanamatira yakavhurika

Izvi zvinorevei?

Iyi generic powertrain diagnostic dambudziko kodhi (DTC) inoshanda kune akawanda OBD-II mota dzedhiziri (1996 kusvika). Izvi zvinogona kusanganisira, asi hazvirevi kune, Chevrolet, GMC, Ford, Mitsubishi, VW, Sprinter, Audi, nezvimwe. Kunyangwe hazvo zvakasarudzika, matanho chaiwo ekugadzirisa anogona kusiyana zvichienderana negore remodheru, gadzira, modhi uye kutamisa kumisikidza.

OBD-II DTC P20A4 uye makodhi akabatanidzwa P20A0, P20A1, P20A2, P20A3, uye P20A5 zvinofambidzana neiyo inoderedza purge control valve valve wedunhu. Iyi dunhu inozivikanwa zvakare seDizili Exhaust Liquid (DEF) system.

Chinangwa cheye reductant purge vheji wedunhu kutumira chiratidzo kune iyo simba rekutonga module (PCM) kana injini yekudzivirira module (ECM) senge poindi yekunongedzera kuti uone kana iyo inodzora pombi inoda kudzosera kuyerera uye kuchenesa iyo DEF system. Maitiro aya anoshandiswa kubatsira kushandura zvasara zvimedu zvemukati zvive magasi asingakuvadzi. Iyo DEF system yakagadzirirwa kushandura inokuvadza maNox magasi kuita nitrogen, carbon dioxide nemvura kuchengetedza nharaunda.

Kana iyo PCM kana ECM yaona kuti iyo inodzora purge control vharuvhu yakanamirwa yakavhurika, kodhi P20A4 inozoisa uye cheki yekuongorora injini ichavhenekera.

Makanika

Chii chakakomba cheiyi DTC?

Kuomarara kwekodhi iyi kunowanzo kuve pakati nepakati, asi P20A4 inogona kuve yakakomba kana magasi anotyisa abviswa kubva mukudzima, zvoita nyaya yekuchengetedza inoda kutariswa nekukasira.

Ndezvipi zvimwe zvezviratidzo zvekodhi?

Zviratidzo zveP20A4 kodhi kodhi inogona kusanganisira:

• Inotadza injini kuita
• Kuderedzwa kwehupfumi hwemafuta
• Tarisa injini mwenje iriko

Ndezvipi zvimwe zvezvikonzero zvinowanzoitika zveiyo kodhi?

Zvikonzero zveiyi P20A4 kodhi inogona kusanganisira:

• Kuderedza mumiriri kuchenesa kudzora vharuvhu chakaremara
• Yakashata kana yakanganisa wiring
• Yakasununguka kana isina kukwana control module pasi tambo
• Yakaora, yakakuvadzwa kana yakasununguka yekubatanidza
• Fuse isina kukwana kana jumper (kana zvichibvira)
• PCM inokanganisa kana ECM

Ndeapi matanho eP20A4 ekugadzirisa?

Nhanho yekutanga mukugadzirisa chero dambudziko nderekutarisa mota-yakatarwa technical Service Bulletins (TSBs) pagore, modhi, uye kudyara kwemagetsi. Mune zvimwe zviitiko, izvi zvinogona kukuserera nguva yakawanda mukufamba kwenguva nekukunongedzera munzira kwayo.

Nhanho yechipiri ndeyekutsvaga zvese zvinosanganisirwa neiyo reductant purge control valve wedunhu uye tarisa kukuvara kuri pachena kwemuviri. Zvichienderana nemotokari chaiyo, DEF system inogona kusanganisira zvikamu zvakasiyana-siyana, kusanganisira pombi yemagetsi reductant, purge valve, pressure sensor, integral level sensor, tembiricha sensor, system heaters, filters, magetsi anodzorwa reductant injector, uye reservoir. Ita ongororo yakakwana yekuona kuti waya wakabatana nawo kune zvakakanganisika zvakaita sekukwenya, mabrasions, waya dziri pachena, kana mavanga ekutsva. Tevere, tarisa zvinobatanidza uye zvinongedzo zvekuchengetedza, ngura uye kukuvadzwa kune vanobatika. Maitiro aya anofanirwa kusanganisira ese ekubatanidza wiring nekubatanidza kune zvese zvikamu zvinosanganisira PCM kana ECM. Tarisa kune chaiyo technical data sheet yemota kuti uone kana fuse kana fuse link inosanganisirwa mudunhu.

Yepamberi nhanho

Matanho ekuwedzera anova akanangana nemotokari uye anoda akakodzera michina yemhando yepamusoro kuti iitwe nemazvo. Maitiro aya anoda digital multimeter uye mota yakanangana nehunyanzvi mareferenzi magwaro. Mune ino mamiriro, yekumanikidza geji inogona zvakare kudikanwa kuti igadzirise iyo yekutambudzika maitiro.

Voltage bvunzo

Iwo mareferenzi emagetsi uye anotenderwa mabara anogona kusiana zvichienderana neicho chaicho mota uye wedunhu kumisikidzwa. Dzakananga data rehunyanzvi rinosanganisa matafura ekugadzirisa matambudziko uye kuteedzana kwakakodzera kwematanho ekukubatsira kunyatsoongorora chirwere.

Kana izvi zvikaona kuti panowanikwa simba kana ivhu, kuenderera kwekutarisa kungangodikanwa kuti uone kutendeka kwewiring, zvinongedzo, nezvimwe zvinhu. Kuenderera mberi bvunzo dzinofanira kugara dzichiitwa nesimba rakabviswa kubva mudunhu uye zvakajairwa kuverenga kwewiring uye kubatana kunofanirwa kunge kuri 0 ohms yekudzivirira. Kuramba kana kusaenderera kunoratidzira isina waya wiring iyo yakavhurika kana kupfupiswa uye inoda kugadzirisa kana kutsiva. Kuenderera mberi kuyedzwa kubva kuPCM kana ECM kune furemu kunosimbisa kutendeka kwetambo dzepasi uye waya dzepasi. Kuramba kunoratidza kubatana kwakasununguka kana kuita kunogona kuita ngura.

Ndedzipi nzira dzakajairika dzekugadzirisa iyi kodhi?

• Kutsiva iyo Reductant Purge Control Valve
• Kuchenesa zvinongedzo kubva kuora
• Gadzirisa kana kutsiva isina waya wiring
• Kutsiva fuse inoputika kana fiyuzi (kana zvichibvira)
• Kugadzirisa kana kutsiva kwakakanganisika ekumisikidza matepi
• Kupenya kana kutsiva PCM kana ECM

Kukanganisa kwakawanda

• Kutsiva iyo inodzora purge control vharuvhu, inosanganisirwa DEF, PCM, kana ECM painokanganisa wiring inokonzeresa kodhi iyi.

Ndinovimba ruzivo rwuri muchinyorwa chino rwakabatsira kunongedzera iwe munzira kwayo yekugadzirisa chinodzora purge control vharuvha yedunhu DTC dambudziko. Ichi chinyorwa ndechekuziva ruzivo chete uye yakatarwa technical data uye sevhisi bulletin yemota yako inofanira kugara ichikoshesa.
