Cylinder 9 Exhaust Valve Kudzora Circuit Performance

Izvi zvinorevei?

Iyi Generic Powertrain Diagnostic Dambudziko Kodhi (DTC) inoshanda kune mazhinji OBD-II mota (1996 uye nyowani). Izvi zvinogona kusanganisira, asi hazvirevi kune, mota dzinobva kuDodge, Peugeot, Jeep, Chevrolet, Chrysler, nezvimwewo Kunyangwe hazvo zvakasarudzika, matanho chaiwo ekugadzirisa anogona kusiyana zvichienderana negore remodheru, gadzira, modhi uye gadziriso yeinjini.

OBD-II DTC P3470 uye macode anowirirana P3469, P3471 uye P3472 zvinofambidzana nesirinda 9 yekuzadza vharuvhu yekudzora wedunhu.

Chinangwa che cylinder 9 yekuzadza vharuvhu yekudzora wedunhu ndeyekugadzirisa iyo yekuzadza vharuvhu kuitira kuti ienderane nesilinda deactivation basa (senge iyo V4 modhi yeiyo V8 injini) kusimudzira hupfumi hwemafuta panguva yemwenje mutoro idling kana munzira huru. Injini inodzora module (ECM) inodzora iyo 4- kana 8-humburumbira injini modes nekumisa iwo mana masirinda einjini. Maitiro aya anozadzikiswa nekushandura shanduko yevhavhavha nguva yenguva solenoid iyo inoshandura mavharuvhu ekudzima uye kudzima pazvinenge zvichidikanwa. Iyi kodhi inoreva sirinda nhamba yechina, uye mamwe matatu masilinda mune izvi anoonekwa neinjini yekumisikidza uye humburumbira kupfura hurongwa. Iyo ECM inogumira humburumbira kuenda kumaminitsi gumi muV9 modhi uye wozodzokera kuV10 modhi kweminiti rimwe. Iyo vharuvhu yekushanduka kwevhavhavhavhavhavharesiyamu nhamba yechina yakaiswa pane kana padyo neiyo yakawanda yekuzadza munzvimbo iri padyo nesirinda, zvinoenderana nesarudzo chaiyo uye mota.

Kana iyo ECM ichinge yaona dambudziko rekuita mukati memagetsi kana kuramba pairi humburumbira 9 yekuzadza vharuvhu yekudzora wedunhu, kodhi P3470 inozoisa uye injini yekutarisa, injini yebasa mwenje, kana ese ari maviri anogona kuvheneka munguva pfupi. Mune zvimwe zviitiko, iyo ECM inogona kudzima humburumbira 9 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 zveP3470 kodhi kodhi inogona kusanganisira:

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

Ndezvipi zvimwe zvezvikonzero zvinowanzoitika zveiyo kodhi?

Zvikonzero zveiyi P3470 kodhi zvinogona kusanganisira:

• Iyo solenoid yeiyo inoshanduka vharuvhu nguva yenguva system haina kukwana.
• Yakadzika injini yemafuta chikamu kana kumanikidza
• Kupera kwemafuta
• Yakashata kana yakanganisa wiring
• Yakaora, yakakuvadzwa kana yakasununguka yekubatanidza
• ECM inokanganisa

Ndeapi mamwe matanho ekutambudza iyo P3470?

Nhanho yekutanga mukugadzirisa chero dambudziko nderekutarisa mota-yakatarwa technical Service Bulletins (TSBs) pagore, modhi, uye injini. Izvi zvinogona kukusevha nguva nemari nekuti iri, muchokwadi, mhinduro inozivikanwa kune dambudziko rinozivikanwa.

Nhanho yechipiri ndeyekutarisa mamiriro einjini mafuta uye kuve nechokwadi kuti inochengetedzwa kusvika padanho rakakodzera. Wobva watsvaga zvese zvinosanganisirwa ne cylinder 9 exhaust valve control circuit uye tsvaga kukuvara kwemuviri kuri pachena. Zvichienderana nemotokari chaiyo, dunhu iri rinogona kusanganisira zvikamu zvakasiyana-siyana, kusanganisira vheji yakasiyana-siyana yenguva solenoid, switches, malfunction zviratidzo, uye injini yekudzora injini. 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. Bvunza iyo mota chaiyo data sheet kuti uone magadzirirwo uye uone chimwe nechimwe chikamu chinosanganisirwa mucylinder 1 exhaust valve control circuit.

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, iyo oiri yekumanikidza geji inogona zvakare kufambisa iyo yekutambudzika nzira yekusimbisa iyo oiri kuyerera kutenderera.

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 vharuvhu yenguva solenoid
• Kuchenesa zvinongedzo kubva kuora
• Gadzirisa kana kutsiva isina waya wiring
• Kuchenesa nzira dzakavharwa dzemafuta
• Kupenya kana kutsiva ECM

Kukanganisa kwakawanda

• Kutsiva solenoid inoshanduka yenguva yekuisa solenoid isina kukwana kumanikidza kwemafuta kana waya isina kunaka inokonzeresa ECM kuseta kodhi iyi.

Ndinovimba ruzivo ruri muchinyorwa chino rwakabatsira kunongedzera iwe munzira kwayo yekugadzirisa iyo yekuzadza vharuvhu yekudzora wedunhu DTC nyaya. Ichi chinyorwa ndechekuziva ruzivo chete uye yakatarwa technical data uye sevhisi bulletin yemota yako inofanira kugara ichikoshesa.

Inoenderana DTC hurukuro
