P2231 Short circuit mu O2 sensor signal dera to heater dera, bank 1, sensor 1

P2231 Short circuit mu O2 sensor signal dera to heater dera, bank 1, sensor 1

Mapepala a OBD-II DTC

Dongosolo la O2 Sensor Signal Idasinthidwa kukhala Heater Bank 1 SENSOR 1

Kodi izi zikutanthauzanji?

Iyi ndi generic Diagnostic Trouble Code (DTC) yogwiritsidwa ntchito pamagalimoto ambiri a OBD-II (1996 ndi atsopano). Izi zingaphatikizepo koma sizingokhala pa VW, Kia, Peugeot, BMW, Cadillac, Holden, Honda, Ford, ndi zina zambiri.

Khodi yosungidwa P2231 imatanthawuza kuti gawo la powertrain control module (PCM) lapeza kachipangizo kakang'ono ka oxygen (O2) ya injini ya banki yoyamba. Bank one ndi gulu la injini lomwe lili ndi silinda yoyamba. Sensor 1 imazindikiritsa sensor yakumtunda (pre-sensor) mu sensa yachitatu (mosiyana ndi makina a sensor anayi).

PCM imagwiritsa ntchito zolowetsa kuchokera kumatenthedwe otentha a oxygen (HO2S) kuwunika momwe mpweya ulili m'mafuta otulutsira banki iliyonse ya injini, komanso kusinthasintha kwa othandizira.

Masensa a oxygen amamangidwa pogwiritsa ntchito zirconia sensing element yomwe ili mkatikati mwa nyumba yazitsulo. Maelekitirodi ang'onoang'ono a platinamu amagulitsidwa pakati pazomwe zimazindikira komanso mawaya olumikizira kachipangizo ka oxygen. Chojambulira cha O2 chojambulira chimalumikizidwa ndi netiweki yolamulira (CAN), yolumikizira cholumikizira cha oxygen ndi cholumikizira cha PCM.

HO2S iliyonse imakhala ndi ulusi (kapena ma Stud) mu chitoliro chotulutsa kapena zochulukirapo. Ili bwino kotero kuti chinthu chofunafuna chili pafupi kwambiri ndi chitoliro. Mpweya utsi kutuluka chipinda kuyaka (mwa zobwezedwa zobwezedwa) ndi kudutsa dongosolo utsi (kuphatikizapo converters othandizira); ikudontha pamasensa oksijeni. Mpweya wotulutsa utsi umalowa mu kachipangizo ka oxygen kudzera muzitsulo zopangidwa mwapadera m'nyumba zazitsulo ndikuzungulira mozungulira. Mpweya womwe umakokedwa ndi zingwe zazinyumba zanyumba yadzaza chipinda chaching'ono chapakatikati pa sensa. Mpweya wotentha (m'chipindacho) umapangitsa ma ayoni a oxygen kuti apange mphamvu, yomwe PCM imazindikira kuti ndi yamagetsi.

Kusiyanitsa pakati pa kuchuluka kwa ma O2 ions mumlengalenga mozungulira ndi kuchuluka kwa mamolekyulu a oksijeni omwe amatulutsa utsi kumapangitsa kuti ma ion a okosijeni otentha mkati mwa HO2S agundike mwachangu komanso mosadukiza kuchokera pa pulatinamu wosanjikiza mpaka wotsatira. Ma ayoni a oxygen akamayenda pakati pa magawo a platinamu, magetsi a HO2S amasintha. PCM imawona kusintha kumeneku mu mphamvu yotulutsa HO2S monga kusintha kwa mpweya wa oxygen mumafuta otulutsa utsi.

Zotsatira zamagetsi zochokera ku HO2S ndizotsika pomwe mpweya wambiri umakhalapo mu utsi (wowonda) komanso wokwera kwambiri pomwe mpweya wocheperako umakhalapo mu utsi (chuma). Gawo ili la HO2S limagwiritsa ntchito mphamvu yamagetsi yotsika (yochepera volt imodzi).

Mu gawo lina la sensa, HO2S imakonzedweratu pogwiritsa ntchito magetsi a batri (12 volts). Kutentha kwa injini ikakhala kotsika, batire yamagetsi imawotcha HO2S kuti iyambe kuyang'anira mpweya wa mpweya wotulutsa utsi mwachangu kwambiri.

PCM ikazindikira ma voliyumu omwe sali ovomerezeka, P2231 idzasungidwa ndipo Nyali Yosagwira Ntchito (MIL) itha kuwunikira. Magalimoto ambiri amafunikira mayendedwe angapo (akulephera) kuti ayatse nyali yochenjeza.

Chitsanzo kachipangizo mpweya:

Kodi kuuma kwa DTC kumeneku ndi kotani?

Kufupika kwa HO2S kumatha kubweretsa magwiridwe antchito a injini komanso mavuto osiyanasiyana. Khodi ya P2231 iyenera kufotokozedwa kuti ndi yayikulu ndikuwongolera mwachangu.

Kodi zina mwazizindikiro za code ndi ziti?

Zizindikiro za vuto la P2231 zitha kuphatikiza:

• Kuchepetsa mafuta
• Kuchepetsa ntchito ya injini
• Ma Code Okhutiritsa Osungidwa kapena Ma Code Otsamira / Olemera Otulutsa
• Nyali ya injini yothandizira idzawala posachedwa

Kodi zina mwazomwe zimayambitsa codezi ndi ziti?

Zifukwa za code iyi zitha kuphatikizira izi:

• Zowonongeka zamagetsi / s
• Chowotcha chopindika, chosweka, chosweka, kapena chosadulidwa ndi / kapena zolumikizira
• Zolakwika za PCM kapena PCM zolakwika

Kodi ndi njira ziti zina zothetsera P2231?

Kuzindikira molondola nambala ya P2231 kudzafunika chowunikira, digito volt / ohmmeter (DVOM), ndi gwero lodalirika lazidziwitso zamagalimoto.

Lumikizani chojambulira pa doko lodziwitsa magalimoto ndikupeza ma code onse osungidwa ndi chimango chazomwe zimayimitsidwa. Mudzafunika kulemba uthengawu kuti nambala yanu ikhale yanthawi imodzi. Kenako chotsani ma code ndikuyesa kuyendetsa galimotoyo. Pakadali pano, chimodzi mwazinthu ziwiri zichitike. Mwina P2231 imakonzedwa kapena PCM imalowa munthawi yoyenera.

Ngati codeyo ili pakati ndipo PCM imayamba kukonzekera, zingakhale zovuta kuzizindikira. Zomwe zidapangitsa kuti P2231 isungidwe zitha kuyenera kukulirakulira asanadziwike bwinobwino. Ngati nambala yanu yachotsedwa, pitirizani kuwunika.

Mawonekedwe olumikizira cholumikizira, zithunzi zolumikizira zolumikizira, masanjidwe apazithunzi, zithunzi zolumikizira, ndi zithunzi zazithunzi (zokhudzana ndi nambala yolumikizidwa ndi galimoto) zitha kupezeka pogwiritsa ntchito gwero lazidziwitso zamagalimoto anu.

Yang'anirani zowonera ndi zolumikizira zokhudzana ndi HO2S. Sinthanitsani mawaya odulidwa, owotcha, kapena owonongeka.

Ngati nambala ya P2231 ikupitiliza kukonzanso, yambani injini. Lolani kuti lizizizira mpaka kutentha kwazomwe zimagwiritsidwa ntchito komanso zosachita (ndikumafalitsa posalowerera kapena paki). Lumikizani chojambulira pa doko lodziyimira pagalimoto ndikuwona kulowetsa kwa kachipangizo ka oxygen mumtsinje wa data. Chepetsani kutsika kwanu kuti muphatikize zokhazo zofunikira kuti muyankhe mwachangu.

Ngati masensa a oxygen akugwira ntchito bwino, ma voliyumu opyola masensa a oksijeni kumtunda kwa chosinthira chazizindikiro azingoyenda mosalekeza kuchokera pa 1 mpaka 900 millivolts pomwe PCM ilowa mumalowedwe otsekedwa. Masensa a Post-Cat azizunguliranso pakati pa 1 ndi 900 millivolts, koma adzakwezedwa panthawi inayake ndikukhala olimba (poyerekeza ndi masensa amkati amphaka). HO2S yomwe sikugwira ntchito moyenera imayenera kuonedwa ngati yopanda ntchito ngati injini ikugwira bwino ntchito.

Ngati HO2S ikuwonetsa batire yamagetsi kapena yamagetsi pamagetsi osakira, gwiritsani ntchito DVOM kuti mupeze zenizeni zenizeni kuchokera ku cholumikizira HO2S. Zotsatira zake zikakhala chimodzimodzi, ganizirani mwachidule HO2S yamkati yomwe ingafune kusinthidwa.

• Nthawi zambiri, mutha kukonza nambala iyi pochotsa HO2S yoyenera, koma malizitsani matendawo.

Zokambirana zokhudzana ndi DTC

• Pakadali pano palibe mitu yofananira m'mabwalo athu. Tumizani mutu watsopano pamsonkhano tsopano.

Mukufuna thandizo lina ndi code P2231?

Ngati mukufunabe thandizo ndi DTC P2231, 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.
