Kodhi yekodhi P2447

Tsanangudzo yehunyanzvi uye dudziro yekukanganisa P2447

Kodhi yekukanganisa P2447 ine hukama neiyo emissions system. Iyo yechipiri mhepo jekiseni pombi inotungamira mhepo yakananga kune exhaust gasi kuderedza kuburitswa. Inokwevera kunze kwemhepo uye inoimanikidza kuburikidza maviri-imwe nzira yekutarisa mavharuvhu muboka rega rega rekubuda.

Iko kukanganisa kunoratidza kuti pombi yechipiri yemhepo jekiseni system, iyo yakaiswa pane dzimwe mota, yakamira. Chinangwa chehurongwa ndechekumanikidza mweya wemuchadenga kupinda mumhepo yekuburitsa panguva yekutonhora kwekutanga.

Izvi zvinogonesa kupiswa kweasina kupiswa kana kupiswa zvishoma mamorekuru ehydrocarbon murukova rwegasi rekubuda. Inoitika semugumisiro wekupisa kusina kukwana panguva yekutonhora kwekutanga, apo injini iri kushanda pamhepo yakasanganiswa zvikuru yemafuta emhepo.

Sekondari mhepo masisitimu anowanzo kuve nehombe yemhepo pombi muchimiro cheturbine uye relay yekubatidza nekudzima mota yepombi. Kuwedzera solenoid uye cheki vharafu kudzora kuyerera kwemhepo. Mukuwedzera, kune mapombi akasiyana-siyana uye madhakisi akakodzera kushandiswa.

Pasi pekumhanya kwakaoma, pombi yemhepo inodzimwa kudzivirira kuyerera kwemagasi emhepo. Kuti uzviyedze wega, iyo PCM inomisa yechipiri mweya jekiseni system uye mweya mutsva unozotungamirwa kune exhaust system.

Oxygen sensors inoona iyi mweya mutsva semamiriro akaipa. Mushure meizvi, kugadziriswa kwenguva pfupi kwemafuta ekufambisa kunofanira kuitika kubhadhara musanganiswa wakaonda.

Iyo PCM inotarisira kuti izvi zviitike mukati memasekondi mashoma panguva yekuzviedza. Kana iwe usingaoni kuwedzera kwekanguva kwemafuta emafuta, ipapo PCM inodudzira izvi sekusashanda mune yechipiri mweya jekiseni system uye zvitoro kodhi P2447 mundangariro.

Kukanganisa zviratidzo

Chiratidzo chekutanga cheP2447 kodhi yemutyairi ndeye MIL (Malfunction Indicator Lamp). Inonziwo Check Engine kana kungoti "cheki iripo".

Vanogonawo kutaridzika se:

1. Tamba yekudzora "Check injini" ichavhenekera pane control panel (iyo kodhi ichachengetwa mundangariro sekusashanda).
2. Pane dzimwe motokari dzeEurope, chiedza chenyevero yekusvibiswa chinouya.
3. Mhepo yepombi ruzha nekuda kwekupfeka kwemagetsi kana zvinhu zvekunze mupombi.
4. Injini haina kumhanya zvakanaka.
5. Injini inogona kumhanya yakawandisa kana mweya wakawandisa ukapinda mu exhaust manifold.
6. Dzimwe nguva panogona kunge pasina zviratidzo zvisinei neDTC yakachengetwa.

Kuomarara kwekodhi iyi hakuna kukwirira, asi mota haigone kupasa bvunzo yekubuda. Kubva pakaonekwa kukanganisa P2447, kupera kwehupfu kuchawedzera.

Zvikonzero zvekukanganisa

Code P2447 inogona kureva kuti imwe kana akawanda ematambudziko anotevera aitika:

• Yakanganisa yechipiri mhepo pombi relay.
• Pombi cheki mavharuvhu akaremara.
• Dambudziko nekutonga solenoid.
• Kutsemuka kana kudonha muhosi kana mhepo ducts.
• Carbon inoisa pahosi, chiteshi uye zvimwe zvikamu.
• Hunyoro hunopinda mupombi uye mota.
• Kupwanya kana kuvhiringwa kwesimba rekupa kune pombi mota nekuda kwekusabatana zvakanaka kana kukuvadzwa waya.
• Sekondari pombi yepombi yemhepo yakafuridzwa.
• Dzimwe nguva PCM yakaipa ndiyo inokonzera.

Nzira yekugadzirisa kana kugadzirisa zvakare DTC P2447

Vamwe vakakurudzira matanho ekugadzirisa dambudziko rekugadzirisa kukanganisa kodhi P2447:

1. Batanidza OBD-II scanner kune yemotokari yekuongorora socket uye uverenge ese akachengetwa data uye kukanganisa makodhi.
2. Gadzirisa chero zvimwe zvikanganiso usati waenderera mberi nekuongorora kodhi P2447.
3. Ongorora tambo dzemagetsi nezvibatanidza zvine chekuita nepombi yechipiri yemhepo.
4. Gadzirisa kana kutsiva chero zvipfupi, zvakatyoka, zvakakuvara, kana kuita ngura sezvinodiwa.
5. Tarisa yechipiri mhepo pombi relay.
6. Tarisa chipiri chepombi yepombi yemhepo.

Kuongororwa uye kugadzirisa matambudziko

Code P2447 inoiswa kana pasina mhepo yekunze yekupisa yakawandisa mahydrocarbon mu exhaust system panguva yekutonhora kwekutanga. Izvi zvinoita kuti voltage iri kumberi kweokisijeni sensor irege kudonha kusvika padanho rakatarwa.

Nzira yekuongorora inoda kuti injini itonhore; zvakanaka, mota yakamira kweinenge 10-12 maawa. Pashure paizvozvo, unofanira kubatanidza diagnostic mudziyo uye kutanga injini.

Iyo voltage iri pamberi peokisijeni sensor inofanira kudonha pazasi 0,125 volts muinenge 5 kusvika 10 masekonzi. Mhosho mumhepo yechipiri inozosimbiswa kana voltage isingadonhe kune iyi kukosha.

Kana voltage ikasadonha kusvika pa 0,125V asi iwe unonzwa pombi yemhepo ichimhanya, tarisa mahosi ese, mitsetse, mavharuvhu, uye solenoids painobuda. Zvakare iva nechokwadi chekutarisa hose dzese, mitsetse uye mavharuvhu kune zvipingamupinyi zvakaita secarbon buildup kana zvimwe zvinovharika.

Kana pombi yemhepo ikasabatidzwa, tarisa ese akakodzera fuse, relay, wiring, uye pombi mota kuti ienderere mberi. Tsiva kana gadzirisa zvinhu zvakakanganisika sezvinodiwa.

Kana macheki ese apera asi iyo P2447 kodhi ichienderera, iyo exhaust manifold kana silinda musoro ungangoda kubviswa. Kuwanikwa kune system ports yekuchenesa kabhoni deposits.

Ndedzipi mota dzinowanzova nedambudziko iri?

Dambudziko nekodhi P2447 rinogona kuitika pamichina yakasiyana-siyana, asi pane nguva dzose nhamba dzemhando iyo kukanganisa uku kunowanzoitika. Heino rondedzero yezvimwe zvacho:

• Lexus (Lexus lx570)
• Toyota (Toyota Sequoia, Tundra)

NeDTC P2447, dzimwe nguva zvikanganiso zvinogona kusangana. Anonyanya kuzivikanwa ndeaya anotevera: P2444, P2445, P2446.
