P0420 Catalyst System Kubudirira Pazasi peChikumbaridzo

Tsanangudzo yehunyanzvi yekukanganisa P0420

Catalyst System Effective Below Threshold (Bhangi 1)

Ko kodhi P0420 inorevei?

Iyi Yekuongorora Dambudziko Kodhi (DTC) ndeye yakajairika kodhi yekufambisa. Inoonekwa seyese kwese kwazvinoshanda kune zvese zvinogadzira uye mamodheru emota (1996 uye nyowani), kunyangwe nhanho dzakananga dzekugadzirisa dzingasiyana zvishoma zvichienderana nemhando yacho. Saka ichi chinyorwa chine injini kodhi chinoshanda kuNissan, Toyota, Chevrolet, Ford, Honda, GMC, Subaru, VW, nezvimwe.

P0420 nderimwe remakodhi akajairika ematambudziko atinoona. Mamwe macode akakurumbira anosanganisira P0171, P0300, P0455, P0442, nezvimwewo. Saka iva nechokwadi chekuisa bhukimaki ino saiti kuti utarise mune ramangwana!

Iyo catalytic converter chikamu cheiyo exhaust system inoita senge muffler, kunyangwe mashandiro ayo akasiyana zvakanyanya neayo muffler. Basa re catalytic converter ndere kudzikisa exhaust emissions.

Icho chinogadzirisa chinoshandura chine oxygen oxygen kumberi nekumashure. Kana mota yadziya uye ichishanda yakavharika loop mode, kuverenga kwechiratidzo kweiyo yekumusoro kweoksijeni sensor inofanirwa kuchinja. Iyo yekudzika yeO2 sensor kuverenga inofanira kunge yakagadzikana zvine mutsindo. Kazhinji, iyo P0420 kodhi inozobatidza cheki injini mwenje kana kuverengwa kwema sensors maviri kwakafanana. Oxygen sensors inonziwo maO2 sensors.

Izvi zvinoratidza (pakati pezvimwe zvinhu) izvo mushanduri asiri kuita nemazvo sezvazvinofanira (zvinoenderana nezvinotsanangurwa). Vashanduri veCatalytic havawanzo kuverengerwa se "kusakara," zvichireva kuti havasimbe uye havafanirwe kutsiviwa. Kana vakakundikana, mikana yaive nekuda kwechimwe chinhu chakakonzera kuparara. Izvi ndizvo zvinomiririrwa neP0420 nenzira yakareruka.

Zviratidzo zvekukanganisa P0420

Chiratidzo chekutanga chemutyairi ndiyo MIL yakavhenekerwa. Iwe haugone kuona chero matambudziko ekubata, kunyangwe paine zviratidzo. Semuenzaniso, kana chinhu chiri mukati mechinoshandura chinokatyamadza kana chisina kurongeka, chinogona kudzora kuburitswa kwemweya wemweya, zvichikonzera kunzwa kwekudzikiswa kwesimba remotokari.

• Hapana zviratidzo zvinoonekwa kana matambudziko ekubata (akajairika)
• Ita shuwa kuti mwenje weinjini wakabatidzwa
• Hapana simba mushure mekunge mota yadziya
• Kumhanya kwemotokari hakugoni kudarika 30-40 mph
• Zai rakaora rinonhuwa kubva pakupera

Zvikonzero zveP0420 kodhi

Iyo P0420 kodhi inogona kureva kuti chimwe kana zvimwe zvezviitiko zvinotevera zvaitika:

• Mafuta anotungamira anoshandiswa panodiwa mafuta asina kuvhurwa (zvingangoita)
• Yakakuvara kana kukundikana oxygen / O2 sensor
• Pasi pemvura oxygen sensor (HO2S) wiring yakakuvara kana zvisirizvo zvakabatana
• Injini inotonhorera tembiricha sensor isiri kushanda nemazvo
• Yakakuvara kana inodonhedza chiutsi chakasiyana / chinogadziridza chinoshandura / muffler / pombi pombi
• Inokanganisa kana isina kukwana inoshanda chinogadzirisa chinoshandura (pamwe)
• Galvanzie kunonoka
• Oxygen sensors kumberi uye kumashure kwekutepfenyura iri kupa zvakaenzana kuverenga.
• Inodonha mafuta injector kana yakanyanya mafuta kumanikidza
• Gutsa humburumbira
• Kusvibiswa kwemafuta

Mhinduro dzinogoneka

Mamwe matanho akakurudzirwa ekugadzirisa matambudziko uye kugadzirisa iyo P0420 kodhi inosanganisira:

• Tarisa uone kupera kwekudonha mune dzakawanda, mapaipi, chinogadzirisa chinoshandura. Gadzirisa kana zvichidikanwa.
• Shandisa oscilloscope kuongorora iyo oksijeni sensor (Zano: iyo okisijeni sensor pamberi pechinoshandura chinoshandura kazhinji ine oscillating waveform. Iyo waveform yeiyo sensor kuseri kwechinoshandura inofanira kunge yakagadzikana).
• Wongorora yakadzika inopisa okisijeni sensor uye kutsiva kana zvichidikanwa.
• Tsiva chinogadzirisa chinogadzirisa.

Zano rekuziva

Kazhinji kutaura, iwe unogona kuona yekupedza tembiricha nguva isati yapfuura uye nekukurumidza mushure mekushandura ine infrared thermometer. Kana injini yanyatsodziya, iyo tembiricha yekubuda inofanirwa kuve ingangoita zana degrees Fahrenheit kumusoro.

Pakazere, pamwe kukanganisa kukuru kwevaridzi vemotokari kana vaine P0420 kodhi ndeyekungotsiva iyo okisijeni sensor (sensor 02). Zvakakosha kuita ongororo chaiyo kuitira kuti usatambise mari pane zvisingakoshi zvekutsiva zvikamu.

Isu tinokurudzira zvakasimba kuti kana iwe uchida kutsiva iyo catalytic converter, itsive neyakagadzirwa brand mudziyo wepakutanga (kureva kuti uwane kubva kune mutengesi). Yechipiri sarudzo imhando yekutsiva chikamu, senge yepamutemo 50-nyika katsi. Kune nyaya dzakawanda pamaforamu edu evanhu vanotsiva katsi neyakachipa aftermarket imwe chete kuti kodhi idzoserwe munguva pfupi yapfuura.

Izvo zvinofanirwa kucherechedzwa kuti vazhinji vagadziri vemota vanopa mawaranti akareba pane zvikamu zvine chekuita nemweya. Naizvozvo, kana iwe uine mota nyowani asi isina kuvharwa neye bhamba-kune-bhurandi garandi, panogona kuve kuchine garandi yeiyi mhando yedambudziko. Vazhinji vagadziri vanopa zvigadzirwa izvi zvine makore mashanu-asingagumi mileage waranti. Izvo zvakakosha kuti utarise.

SEI MACHANIC DIAGNOSTIC CODE P0420?

• Shandisa OBD-II scanner kudzoreredza makodhi ematambudziko akachengetwa kubva kuPCM.
• Inoratidza mhenyu data yepasi (kumashure) oxygen sensor. Iko kudzika kweokisijeni sensor voltage kuverenga kunofanirwa kugara kuripo. Sarudza kana iyo yakadzika (kumashure) oksijeni sensor iri kushanda nemazvo.
• Ongorora chero mamwe macode angave ari kukonzera DTC P0420.
• Gadzirisa kukanganisa, kukanganisa uye / kana mafuta system matambudziko sezvinodiwa.
• Inotarisa kumashure kweokisijeni sensor yekukuvara uye / kana kupfeka zvakanyanya.
• Kuedza kutyaira mota inotarisa kugadzika furemu data kuona kana iyo yakadzika (kumashure) oksijeni sensor iri kushanda nemazvo.
• Tarisa uone iripo PCM inogadziridza kana iyo catalytic converter inokanganisa. Mushure mekutsiva iyo catalytic converter, PCM inogadziridza inozodiwa.

ZVIKANGANISO ZVAUNOGONA KUONA CODE P0420

Chikanganiso chakanyanya kutsiva maokisijeni masensa nzira yekuongorora isati yapera. Kana chimwe chikamu chiri kukonzera iyo P0420 dambudziko kodhi, kutsiva iyo okisijeni sensors haigadzirise dambudziko.

KODEI P0420 YAKAKANYA SEI?

Zvakajairika kuti mutyairi ashaye matambudziko ekubata kana P0420 DTC iripo. Kunze kwekunge Cheki Engine mwenje ichibatidzwa, zviratidzo zveiyi DTC zvinogona kuenda zvisingaonekwe. Nekudaro, kana mota ikasiiwa nekukanganisa pasina kugadzirisa dambudziko, inogona kukonzera kukanganisa kwakanyanya kune zvimwe zvikamu.

Sezvo pasina zviratidzo zvekugadzirisa matambudziko ane chokuita neDTC P0420, izvi hazvionekwi zvakakomba kana kuti zvine ngozi kumutyairi. Nekudaro, kana iyo kodhi isina kugadziriswa nenguva, iyo catalytic converter inogona kukuvara zvakanyanya. Nekuti kugadzirisa kwecatalytic converter kunodhura, zvakakosha kuti DTC P0420 iongororwe uye igadziriswe nekukurumidza.

KUGADZIRIRA KUNOGONA KUGADZA CODE P0420?

• Tsiva muffler kana kugadzirisa muffler inobuda
• Tsiva manifold exhaust kana gadzirisa kubuda kwemvura zhinji.
• Tsiva hose yedrain kana gadzirisa dhiraivha hose inobuda.
• Tsiva catalytic converter (yakajairika)
• Tsiva Injini Inotonhorera Temperature Sensor
• Kutsiva kumberi kana kumashure kweokisijeni sensor
• Gadzirisa kana kutsiva wiring yakakanganisika kune okisijeni sensors.
• Gadzirisa kana kutsiva oxygen sensor connectors
• Tsiva kana gadzirisa majekiseni emafuta ari kubuda
• Kuongorora chero matambudziko asina kunaka
• Ongorora uye gadzirisa chero mamwe ane hukama makodhi makodhi akachengetwa nemagetsi manejimendi module (PCM).

KUWEDZERA MACOMMENTS KUTI UZIVE CODE P0420

Matambudziko neiyo ignition system, mafuta system, kutorwa kwemhepo, uye misfires inogona kukuvadza inoshandura inoshandura kana ikasagadziriswa nekukurumidza. Izvi zvikamu ndizvo zvinonyanya kukonzera DTC P0420. Paunenge uchitsiva catalytic converter, zvinokurudzirwa kuti uitsive neiyo yekutanga unit kana yemhando yepamusoro okisijeni sensor.

Aftermarket okisijeni masensa anowanzo kutadza, uye kana izvi zvaitika, iyo P0420 dambudziko kodhi inogona kuoneka zvakare. Iwe unofanirwawo kubata mugadziri kuti uone kana mota yako yakavharwa newaranti yemugadziri pazvikamu zvine chekuita nekubuda.
