Cylinder 7 Deactivation / Inodya Valve Kudzora Dunhu / Vhura

Izvi zvinorevei?

Iyi Generic Powertrain Diagnostic Dambudziko Kodhi (DTC) inoshanda kune mazhinji OBD-II mota (1996 uye nyowani). Izvi zvinogona kusanganisira, asi hazvingogumiri ku, General Motors, Dodge, Jeep, Chevrolet, Chrysler, Ram, nezvimwe. Kunyange hazvo zvakajairika, matanho chaiwo ekugadzirisa anogona kusiyana zvichienderana nemhando yegore, gadzira, modhi, uye gadziriso yekutapurirana.

OBD-II DTC P3449 uye dzinoenderana macode P3450, P3451 uye P3452 zvinofambidzana nesirinda # 7 yekubata vharuvha yekuvhara / kudzora wedunhu.

Chinangwa chesilinda 7 deactivation / yekudyara vharuvhu yekudzora wedunhu kugadzirisa iyo humburumbira deactivation basa (semuenzaniso, V4 modhi yeiyo V8 injini) kugadzirisa hupfumi hwemafuta panguva yechiedza mutoro mashandiro senge mugwagwa mukuru wekutyaira. Injini inodzora module (ECM) inodzora iyo 4- kana 8-humburumbira injini modes, kusanganisira iyo yekuvhara-yekuvhara solenoid mavharuvhu eayo mana masirinda einjini. Iyi kodhi inoreva sirinda nhamba 7, uye mamwe matatu masilinda munzira iyi anotemerwa neinjini yekumisikidza uye humburumbira kupfura hurongwa. Iyo humburumbira deactivation solenoid nhamba imwe yakaiswa kana padyo nenzvimbo iri padyo nesirinda ino, zvichienderana nemota chaiyo nekugadzirisa.

Kana iyo ECM ichinge yaona isina kujairika magetsi kana kusagadzikana mune humburumbira 7 deactivation / yekudyara vharuvhu yekudzora wedunhu, DTC P3449 ichagadzika uye cheki yekuongorora injini ichakurumidza kuvhenekera, injini yebasa reinjini, kana ese ari maviri anogona kuvhenekera. Mune zvimwe zviitiko, iyo ECM inogona kudzima humburumbira # 7 jekiseni kudzimara dambudziko ragadziriswa uye kodhi yacho yagadziriswa, zvichikonzera kuoneka kusanzwisisika kweinjini.

Chii chakakomba cheiyi DTC?

Kuomarara kwekodhi iyi kunogona kusiyana zvakanyanya kubva pakati nepakati kusvika zvakanyanya zvichienderana nezviratidzo zvechinetso. Kufuridzira kwakashata kunoda kutariswa nekukasira sezvo kuchikonzera kukuvara kusingaperi kune zvemukati injini zvikamu.

Ndezvipi zvimwe zvezviratidzo zvekodhi?

Zviratidzo zveP3449 kodhi kodhi inogona kusanganisira:

• Injini inogona kusashanda
• Kuwedzera kwemafuta
• Inotadza injini kuita
• Injini yebasa injini ichave iripo munguva pfupi
• Tarisa injini mwenje iriko

Ndezvipi zvimwe zvezvikonzero zvinowanzoitika zveiyo kodhi?

Zvikonzero zveiyi P3449 kodhi zvinogona kusanganisira:

• Yakaremara humburumbira kudzima solenoid
• Yakadzika injini yemafuta chikamu kana kumanikidza
• Kupera kwemafuta
• Yakashata kana yakanganisa wiring
• Yakaora, yakakuvadzwa kana yakasununguka yekubatanidza
• ECM inokanganisa

Ndeapi mamwe matanho ekutambudza iyo P3449?

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

Yechipiri nhanho ndeyekutarisa mamiriro einjini mafuta uye kuve nechokwadi kuti inochengetedzwa kusvika padanho rakakodzera. Tevere, tsvaga zvese zvinosanganisirwa ne cylinder 7 inlet yekuvhara-off valve control circuit uye tarisa kukuvara kwemuviri kuri pachena. Zvichienderana nemotokari chaiyo, dunhu iri rinogona kusanganisira zvinhu zvakati wandei, zvinosanganisira shutdown solenoid, switch, zviratidzo zvekukanganisa, uye injini yekudzora unit. Ita ongororo yakasimba yekuona kuti waya wakabatana nawo ndeupi hurema huri pachena hwakadai sekukwenya, mabrasions, waya dziri pachena, kana mavanga ekutsva. Tevere, tarisa zvinobatanidza uye zvinongedzo zvekuchengetedza, ngura uye kukuvadzwa kune vanobatika. Iyi nzira inofanirwa kusanganisira zvese zvinobatanidza magetsi uye zvinongedzo kune zvese zvikamu, kusanganisira ECM. Bvunza iyo chaiyo yemotokari data sheet kuti utarise cylinder 7 yekucheka-kubvisa vharafu / inlet valve control circuit configuration uye simbisa chimwe nechimwe chikamu chinosanganiswa mudunhu, chinogona kusanganisira fuse kana fusible link.

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.

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 maitiro aya akaona kuti panowanikwa simba kana ivhu, muedzo wekuenderera mberi ungangodikanwa kuti utarise kuvimbika 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 iyo wiring mhosva iyo yakavhurika, ipfupiswa, kana yakaora uye inoda kugadziriswa kana kutsiviwa.

Ndedzipi nzira dzakajairika dzekugadzirisa iyi kodhi?

• Kutsiva iyo deactivation solenoid
• Kuchenesa zvinongedzo kubva kuora
• Gadzirisa kana kutsiva isina waya wiring
• Oiri uye firita shanduko
• Kuchenesa nzira dzakavharwa dzemafuta
• Kupenya kana kutsiva ECM

Kukanganisa kwakawanda

• Kutsiva iyo deactivation solenoid isina kukwana mafuta kumanikidza kana zvisirizvo wiring zvinoita kuti ECM iise iyi kodhi.

Ndinovimba ruzivo rwuri muchinyorwa chino rwakubatsira kunongedza munzira kwayo yekugadzirisa inlet vharuvhu / humburumbira 7 deactivation yekudzora wedunhu DTC dambudziko.Chinyorwa ichi ndechekuziva ruzivo chete, uye yakatarwa technical data uye sevhisi mabulletin emota yako anofanira kugara achitora kukoshesa.
