Kodi code P0420 imatanthauza chiyani?

Code Yovutikira Kuzindikira (DTC) ndi nambala yotumizira. Imawerengedwa kuti ndiyaponseponse momwe imagwirira ntchito popanga mitundu yonse yamagalimoto (1996 ndi atsopano), ngakhale njira zowongolera zingasiyane pang'ono kutengera mtunduwo. Chifukwa chake nkhaniyi yokhala ndi ma injini imagwira ntchito ku Nissan, Toyota, Chevrolet, Ford, Honda, GMC, Subaru, VW, ndi zina zambiri.

P0420 ndi amodzi mwamavuto omwe timawawona. Ma code ena otchuka akuphatikizapo P0171, P0300, P0455, P0442, ndi zina zotero. Choncho onetsetsani kuti mwaika chizindikiro pa tsamba ili kuti muwagwiritse ntchito mtsogolo!

The catalytic converter ndi gawo la exhaust system yomwe imawoneka ngati muffler, ngakhale kuti ntchito yake ndi yosiyana kwambiri ndi ya muffler. Ntchito ya catalytic converter ndi kuchepetsa utsi wotulutsa mpweya.

Chotembenuza chothandizira chimakhala ndi kachipangizo ka oxygen kutsogolo ndi kumbuyo. Galimoto ikatenthedwa ndikugwira ntchito yotsekedwa, kuwerengera kwa siginecha wa oxygen kuyenera kusinthasintha. Kuwerenga kwapansi kwa O2 sensa kuyenera kukhala kokhazikika. Nthawi zambiri, code ya P0420 imatsegula magetsi ngati cheke cha masensa awiriwa ndi chimodzimodzi. Masensa a oxygen amatchedwanso masensa a O2.

Izi zikuwonetsa (mwazinthu zina) kuti wotembenuza sakuchita bwino momwe ayenera (malingana ndi malongosoledwe). Otembenuza othandizira nthawi zambiri samakhala ngati "otopa," kutanthauza kuti satopa ndipo safunika kusintha ena. Ngati alephera, ndiye kuti zinali chifukwa cha china chake chomwe chidapangitsa ngoziyo. Izi ndi zomwe P0420 imayimira m'njira yosavuta.

Zizindikiro za zolakwika P0420

Chizindikiro chachikulu cha driver ndi MIL yowunikira. Mosakayikira simudzawona zovuta zilizonse zosamalira, ngakhale pakhoza kukhala zizindikilo. Mwachitsanzo, ngati chinthu chomwe chili mkati mwa chosinthira chathyoledwa kapena chasokonekera, chitha kuletsa kutulutsa kwa utsi, zomwe zimapangitsa kuti mphamvu yamagalimoto ichepetse.

• Palibe zizindikiro zowoneka kapena zovuta zogwirira ntchito (zofala kwambiri)
• Onetsetsani kuti kuwala kwa injini kuyatsa
• Palibe mphamvu galimoto ikatenthetsa
• Liwiro lagalimoto silingapitilire 30-40 mph
• Dzira lovunda fungo lochokera ku utsi

Zifukwa za P0420 kodi

Khodi ya P0420 itha kutanthauza kuti chimodzi kapena zingapo mwazimene zachitika:

• Mafuta otsogolera omwe amagwiritsidwa ntchito pomwe pamafunika mafuta opanda zingwe (zosatheka)
• Kuwonongeka kapena kulephera kwa oxygen / O2 sensor
• Makina otsikira pansi a oxygen sensor (HO2S) awonongeka kapena olumikizidwa molakwika
• Kutentha kwa injini sikukugwira bwino
• Kuwonongeka kapena kutuluka kwa utsi kosiyanasiyana / chosinthira chothandizira / chitoliro / chotulutsa chitoliro
• Chosintha kapena chosakwanira chosinthira chothandizira (mwina)
• Kuchepetsa kuyatsira
• Masensa a oxygen kutsogolo ndi kumbuyo kwa wotumiza akuwerenganso chimodzimodzi.
• Kutulutsa jakisoni wamafuta kapena kuthamanga kwamafuta
• Kukwaniritsa yamphamvu
• Kuipitsidwa kwa mafuta

Mayankho otheka

Zina mwazinthu zoyenera kuthana ndi mavuto ndikukonzekera nambala ya P0420 ndi izi:

• Fufuzani kutuluka kwakatundu pamitundu ingapo, mapaipi, chosinthira chothandizira. Konzani ngati kuli kofunikira.
• Gwiritsani ntchito oscilloscope kuti mupeze sensa ya oxygen (Zokuthandizani: kachipangizo ka oxygen patsogolo pa chosinthira chothandizira nthawi zambiri chimakhala ndi mawonekedwe osunthika. Mawonekedwe a sensa kumbuyo kwa chosinthira ayenera kukhala okhazikika).
• Yendani kachipangizo kamene kamatenthetsa mpweya ndipo musinthe ngati kuli kofunikira.
• Sinthani chosinthira chothandizira.

Upangiri wodziwitsa

Nthawi zambiri, mutha kuwona kutentha kwa utsi musanataye nthawi yomweyo mutangotembenuza ndi thermometer ya infrared. Injini ikatenthetsa bwino, kotenthetsako kuyenera kukhala pafupifupi 100 Fahrenheit kupitilira apo.

Ponseponse, mwina cholakwika chachikulu chomwe eni magalimoto amapanga akakhala ndi nambala ya P0420 ndikungolowetsa sensor ya okosijeni (sensor 02). Ndikofunikira kuyezetsa magazi moyenera kuti musawononge ndalama pazigawo zolowa m'malo zosafunikira.

Tikukulimbikitsani kuti ngati mukufuna kusintha chosinthira chothandizira, m'malo mwake ndi chida chamtundu wakale (i.e. chipezeni kwa ogulitsa). Njira yachiwiri ndi gawo lolowa m'malo labwino, monga mphaka wovomerezeka wa boma 50. Pali nkhani zambiri pamabwalo athu za anthu omwe adalowa m'malo mwa mphaka ndikuyika msika wotchipa ndikubweza khodi posachedwa.

Tiyenera kudziwa kuti opanga magalimoto ambiri amapereka zitsimikizo zazitali pazinthu zokhudzana ndi mpweya. Chifukwa chake, ngati muli ndi galimoto yatsopano koma simakutidwa ndi chitsimikizo cha bampala-to-bampala, pangakhalebe chitsimikizo chavutoli. Opanga ambiri amapereka izi ndi chitsimikizo cha mileage yopanda malire yazaka zisanu. Ndikoyenera kufufuza.

KODI MACHHANIC DIAGNOSTIC KODI P0420 Imatani?

• Gwiritsani ntchito scanner ya OBD-II kuti mutengenso ma code ovuta omwe asungidwa kuchokera ku PCM.
• Imawonetsa zidziwitso zamoyo zam'munsi (kumbuyo) sensor ya okosijeni. Kuwerengera kwa mpweya wa oxygen kumunsi kwa mtsinje kuyenera kukhala kosalekeza. Dziwani ngati sensa yakumunsi (kumbuyo) kwa okosijeni ikugwira ntchito bwino.
• Dziwani zizindikiro zina zilizonse zomwe zingayambitse DTC P0420.
• Konzani zolakwika, kusokonekera ndi/kapena zovuta zamakina amafuta pakufunika.
• Imayang'anira sensor yakumbuyo ya okosijeni ngati yawonongeka komanso/kapena kuvala kwambiri.
• Yesani kuyendetsa galimoto imayang'ana data ya chimango kuti muwone ngati sensor yakumunsi (kumbuyo) ya okosijeni ikugwira ntchito bwino.
• Onani zosintha za PCM ngati chosinthira chothandizira chili cholakwika. Pambuyo posintha chosinthira chothandizira, zosintha za PCM zidzafunika.

ZOPHUNZITSA ZAMBIRI PAMENE AMADZIWA KODI P0420

Cholakwika chofala kwambiri ndikuchotsa masensa a okosijeni musanamalize matenda. Ngati chigawo china chikuyambitsa vuto la P0420, kusintha masensa a okosijeni sikungathetse vutoli.

KODI P0420 NDI YOYAMBA BWANJI?

Ndi zachilendo kuti dalaivala asakhale ndi vuto loyendetsa P0420 DTC ilipo. Kupatulapo kuwala kwa Injini Yoyang'ana, zizindikiro za DTC iyi zitha kuzindikirika. Komabe, ngati galimotoyo yasiyidwa molakwika popanda kuthetsa vutoli, ikhoza kuwononga kwambiri zigawo zina.

Popeza palibe zizindikiro za kuthana ndi mavuto okhudzana ndi DTC P0420, izi sizikuwoneka ngati zazikulu kapena zowopsa kwa dalaivala. Komabe, ngati codeyo siyikukonzedwa munthawi yake, chosinthira chothandizira chikhoza kuonongeka kwambiri. Chifukwa kukonza kosinthira ma catalytic ndi okwera mtengo, ndikofunikira kuti DTC P0420 izindikiridwe ndikukonzedwa posachedwa.

KODI KUKONZA KODI KUUNGAKONZE KODI P0420)?

• Bwezerani chopondera kapena kukonzanso kutayikira kwa muffler
• Bwezerani utsi wochulukirachulukira kapena konza utsi wautsi wochulukirachulukira.
• Bwezerani payipi ya drainage kapena kukonzanso kutayikira kwa payipi.
• Sinthani chosinthira chothandizira (chofala kwambiri)
• Bwezerani Injini Yozizira Kutentha Sensor
• Kusintha kutsogolo kapena kumbuyo kwa oxygen sensor
• Konzani kapena sinthani mawaya owonongeka kukhala masensa okosijeni.
• Konzani kapena kusintha zolumikizira mpweya wa oxygen
• Bwezerani kapena konzani majekeseni amafuta akutha
• Kuzindikira zovuta zilizonse zolakwika
• Dziwani ndikuwongolera zovuta zina zilizonse zomwe zasungidwa ndi gawo loyang'anira mphamvu (PCM).

ZOWONJEZERA ZOWONJEZERA KUDZIWA KODI P0420

Mavuto ndi makina oyatsira, makina amafuta, kutengeka kwa mpweya, ndi kuwonongeka kwamoto kumatha kuwononga chosinthira chothandizira ngati sichingathetsedwe mwachangu. Izi ndizomwe zimayambitsa DTC P0420. Mukasintha chosinthira chothandizira, tikulimbikitsidwa kuti musinthe ndi gawo loyambirira kapena sensa yapamwamba kwambiri ya okosijeni.

Masensa a okosijeni a Aftermarket nthawi zambiri amalephera, ndipo izi zikachitika, nambala yamavuto ya P0420 imatha kuwonekeranso. Muyeneranso kulankhulana ndi wopanga galimoto yanu kuti muwone ngati galimoto yanu ili ndi chitsimikizo cha wopanga pazinthu zokhudzana ndi mpweya.

Mukufuna thandizo lina ndi nambala yanu ya p0420?

Ngati mukufunabe thandizo ndi DTC P0420, lembani funso mu ndemanga pansipa pamutuwu.

ZINDIKIRANI. Izi zimaperekedwa kuti zidziwitse zokha. Sikuti tizigwiritsa ntchito ngati malingaliro okonzanso ndipo sitili ndi udindo pazomwe mungachite pagalimoto iliyonse. Zomwe zili patsamba lino ndizotetezedwa ndi zovomerezeka.
