P042A Chothandizira Kutentha SENSOR Dera Losagwira Bank 1 SENSOR 2

P042A Chothandizira Kutentha SENSOR Dera Losagwira Bank 1 SENSOR 2

Mapepala a OBD-II DTC

Chothandizira Kutentha kwa Sensor Circuit Kukanika (Bank 1 Sensor 2)

Kodi izi zikutanthauzanji?

Izi Diagnostic Trouble Code (DTC) ndi njira yotumizira, zomwe zikutanthauza kuti imagwira ntchito kumagalimoto okhala ndi OBD-II okhala ndi zotentha zotengera (Subaru, Ford, Chevy, Jeep, Nissan, Mercedes-Benz, Toyota, Dodge, etc.) D).). Ngakhale chikhalidwe chonse, njira zowongolera zenizeni zimatha kusiyanasiyana kutengera kapangidwe / kapangidwe kake.

Chosinthira chothandizira ndi chimodzi mwazinthu zofunika kwambiri zamagetsi zamagetsi pagalimoto. Mipweya yotulutsa mpweya imadutsa mu chosinthira chothandizira pomwe ma chemical reaction amachitika. Izi zimasintha carbon monoxide (CO), hydrocarbon (H O) ndi nitrogen oxides (NOx) kukhala madzi opanda vuto (H2O) ndi carbon dioxide (CO2).

Kuchita bwino kwa chosinthira kumayang'aniridwa ndi masensa awiri a oxygen; imodzi imayikidwa patsogolo pa chosinthira ndi china pambuyo pake. Poyerekeza zizindikiro za mpweya (O2) sensor, powertrain control module (PCM) ikhoza kudziwa ngati chosinthira chothandizira chikugwira ntchito bwino. Sensa ya zirconia O2 kumtunda kwa chosinthira chothandizira imasinthiratu chizindikiro chake pakati pa pafupifupi 0.1 ndi 0.9 volts. Kuwerenga kwa 0.1 volts kumasonyeza kusakanikirana kwa mpweya / mafuta, pamene 0.9 volts imasonyeza kusakaniza kolemera. Ngati chosinthira chikugwira ntchito moyenera, sensa yakumtunda iyenera kugwira ntchito modalirika pafupifupi 0.45 volts.

Chothandizira kusintha kwa kutentha ndi kutentha ndizogwirizana. Ngati wotembenuza akugwira ntchito moyenera, kotenthetsako kuyenera kukhala kocheperako kuposa kolowera. Lamulo lakale kwambiri linali madigiri 100 Fahrenheit. Komabe, magalimoto ambiri amakono sangasonyeze izi.

Palibe chenicheni "chothandizira kutentha kutentha". Zizindikiro zomwe zafotokozedwa m'nkhaniyi ndi za kachipangizo ka oxygen. Gawo la Bank 1 la code likuwonetsa kuti vuto lili ndi banki yoyamba ya injini. Ndiye kuti, banki, yomwe imaphatikizapo cholembera # 1. "SENSOR 2" amatanthauza kachipangizo kamene kamayikidwa kumapeto kwa chosinthira chothandizira.

DTC P042A imakhazikitsa PCM ikazindikira kusayenda bwino kwa banki 1 chothandizira kutentha sensa 2.

Kuuma kwa code ndi zizindikilo

Kukula kwa code iyi ndi kwapakatikati. Zizindikiro za nambala ya injini ya P042A itha kuphatikizira:

• Chongani Engine Kuwala
• Kugwiritsa ntchito injini molakwika
• Kuchepetsa mafuta
• Kuchuluka kwa mpweya

zifukwa

Zomwe zingayambitse code P042A ndi izi:

• Operewera kachipangizo mpweya
• Mavuto a zingwe
• Kusakanikirana kosakanikirana kwa mpweya ndi mafuta
• Mapulogalamu olakwika a PCM / PCM

Njira zowunikira ndikukonzanso

Yambani poyang'ana poyang'ana kachipangizo kamene kali ndi oxygen komanso zingwe zolumikizira. Fufuzani malumikizidwe otayirira, zingwe zowonongeka, ndi zina zambiri. Onaninso kutulutsa kotulutsa zonse zowonekera komanso zomveka. Kutulutsa kotulutsa utsi kumatha kuyambitsa kachipangizo konyenga ka oxygen. Ngati kuwonongeka kukupezeka, konzani momwe zingafunikire, chotsani nambalayo ndikuwona ngati ibwerera.

Kenako yang'anani ma bulletins aukadaulo (TSBs) zavutolo. Ngati palibe chomwe chikupezeka, muyenera kupitilira pakuwunika pang'onopang'ono. Otsatirawa ndi njira yodziwika bwino popeza kuyesa kwa nambala iyi kumasiyana ndi galimoto ndi galimoto. Kuti muyesetse bwino dongosololi, muyenera kuyang'ana pa tchati chojambulira cha galimoto yanu.

Fufuzani ma DTC ena

Zizindikiro zamagetsi zamagetsi zimatha kukhazikitsidwa chifukwa cha magwiridwe antchito a injini omwe amayambitsa kusamvana pakati pamlengalenga / mafuta. Ngati pali ma DTC ena osungidwa, mudzafunika kuwachotsa kaye musanapitilize ndi kachipangizo kamene kamapezeka ndi mpweya.

Chongani kachipangizo ntchito

Izi zimapangidwa bwino ndi chida chosakira kapena, osadandaula, oscilloscope. Popeza anthu ambiri alibe mwayi wopeza zambiri, tiwunika kuti tipeze kachipangizo ka oxygen kamene kamakhala ndi chida chojambulira. Lumikizani chida chosakira padoko la ODB pansi pa dashboard. Tsegulani chida chosankhira ndikusankha parameter ya Bank 1 Sensor 2 Voltage pamndandanda wazidziwitso. Bweretsani injini kuti igwiritse ntchito kutentha ndikuwona magwiridwe antchito posanthula.

Chojambuliracho chikuyenera kuwerengedwa bwino kwa 0.45 V ndikusinthasintha pang'ono. Ngati sichikuyankha bwino, mwina chikuyenera kusinthidwa.

Fufuzani dera

Masensa a oksijeni amapanga magetsi awo omwe amatumizidwa ku PCM. Musanapitilize, muyenera kuyang'ana pazithunzi zolumikizira mafakitale kuti mudziwe kuti ndi ma waya ati. Autozone imapereka maupangiri okonza pa intaneti kwaulere pamagalimoto ambiri, ndipo ALLDATADIY imangolembetsa pagalimoto imodzi. Kuti muyese kupitiriza pakati pa sensa ndi PCM, tsegulani batani loyatsa ndikuchotsa cholumikizira cha O2. Lumikizani DMM kukana (kuyatsa) pakati pa O2 sensor sign terminal pa PCM ndi waya wama siginolo. Ngati kuwerengera mita sikulekerera (OL), pali dera lotseguka pakati pa PCM ndi sensa yomwe imayenera kupezeka ndikukonzedwa. Ngati kauntala akuwerenga mtengo wake, pali kupitiriza.

Ndiye muyenera kufufuza maziko a dera. Kuti muchite izi, tembenuzani batani loyatsa ndikuchotsa cholumikizira cha O2. Lumikizani DMM kuti muyese kukana (poyatsira) pakati pa malo oyambira a cholumikizira cha O2 (mbali yolumikiza) ndi chassis ground. Ngati kuwerengera mita sikulekerera (OL), pali dera lotseguka kumbali yazungulira yomwe iyenera kupezeka ndikukonzedwa. Ngati mita iwonetsa mtengo wamawerengero, pamakhala mpumulo wapansi.

Pomaliza, mufunika kufufuza ngati PCM ikugwiritsa ntchito chizindikiro cha sensa ya O2 molondola. Kuti muchite izi, siyani zolumikizira zonse ndikulowetsa zoyeserera kumbuyo kwa PCM. Ikani mphamvu ya DMM ku DC. Ndi injini yotentha, yerekezerani kuwerengera kwamagetsi pamamita ndi kuwerenga kwa chida chosakira. Ngati sakugwirizana, PCM mwina ndiyopunduka kapena iyenera kusinthidwa.

Zokambirana zokhudzana ndi DTC

• Opel Astra P042AOPEL ASTRA H, lembani AH / SW / FX11 / ASTRA STATION WAGON, injini ya 1.7 cc Onani Model A17DTR Error Code P042A ... 

Mukufuna thandizo lina ndi code p042A?

Ngati mukufunabe thandizo lokhudza DTC P042A, 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.
