P2237 O2 Sensor Positive Current Control Circuit / Open Bank 1 SENSOR 1

Tsamba la deta la DTC P2237-OBD-II

O2 Sensor Positive Current Control Circuit / Block 1 Open, Sensor 1

Kodi vuto la P2237 limatanthauza chiyani?

Iyi ndi generic Diagnostic Trouble Code (DTC) yogwiritsidwa ntchito pamagalimoto ambiri a OBD-II (1996 ndi atsopano). Izi zingaphatikizepo, koma sizingokhala ku, Mazda, VW, Acura, Kia, Toyota, BMW, Peugeot, Lexus, Audi, ndi zina zambiri. Ngakhale zili choncho, njira zowongolera zenizeni zimatha kusiyanasiyana kutengera chaka chopanga, mtundu, mitundu ndi zotulutsa.

Khodi yosungidwa P2237 imatanthawuza kuti Powertrain control module (PCM) yapeza kusagwirizana komwe kulipo mu sensa yakumtunda kwa oxygen (O2) ya banki ya injini nambala wani. Bank one ndi gulu la injini lomwe lili ndi silinda yoyamba. Sensor 1 ndiye sensor yapamwamba (pre) Dongosolo labwino lowongolera pano ndi gawo lotsika lamagetsi.

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, P2237 idzasungidwa ndipo Nyali Yosagwira Ntchito (MIL) itha kuwunikira. Magalimoto ambiri amafunikira mayendedwe angapo (akulephera) kuti ayatse nyali yochenjeza.

Chitsanzo mpweya kachipangizo O2:

Kodi kuuma kwa DTC kumeneku ndi kotani?

HO2S yokhala ndi vuto loyendetsa dera likhoza kubweretsa magwiridwe antchito a injini komanso mavuto osiyanasiyana. Khodi ya P2237 iyenera kufotokozedwa kuti ndi yayikulu ndikuwongolera posachedwa.

Kodi zizindikiro za P2237 ndi ziti?

Zizindikiro za vuto la P2237 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 P2237?

Kuzindikira molondola nambala ya P2237 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 P2237 imakonzedwa kapena PCM imalowa munthawi yoyenera.

Ngati codeyo ili pakati ndipo PCM imayamba kukonzekera, zingakhale zovuta kuzizindikira. Zomwe zidapangitsa kuti P2237 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.

Chotsani HO2S yomwe ikufunsidwa ndikugwiritsa ntchito DVOM kuyesa kutsutsana pakati pamagetsi oyendetsa magetsi apano ndi ma circuits aliwonse apansi. Ngati pali kupitiriza, kukayikira HO2S yolakwika.

Ngati nambala ya P2237 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. Ngati zotsatirazo zikufanana, ganizirani mwachidule HO2S ya mkati yomwe ingafune m'malo mwa HO2S.

• Nthawi zambiri, mutha kukonza nambala yamtunduwu m'malo mwa HO2S yoyenera, koma malizitsani matendawo.

KODI MACHHANIC DIAGNOSTIC KODI P2237 Imatani?

• Imayang'ana ma code ndikulemba ma code mu ECM ndikuyang'ana deta ya chimango kuti iwononge zolakwika.
• Imayesa gawo la chotenthetsera cha O2 motsutsana ndi masensa ena a O2 kuti alowemo ndi ma voltages owongolera omwewo.
• Imayesa chotenthetsera cha O2 kuti chikhale chotseguka kapena chachifupi mu sensa.
• Imatsimikizira kuti mawaya a sensa ya O2 safupikitsidwa kuti apereke mphamvu kapena pansi.
• Imayang'ana chingwe cholumikizira chachifupi kapena chotseguka kuchokera ku sensa ya O2 kupita ku ECM.

ZOPHUNZITSA ZAMBIRI PAMENE AMADZIWA KODI P2237?

• Kuchotsa manambala a kukumbukira a ECM musanayambe kuyang'ana deta yowumitsa yachinthu chomwe chimayambitsa vutolo kuti cholakwikacho chibwerezedwe ndikukonzedwanso.
• Zalephera kuyesa zolakwika musanalowe m'malo mwa O2 sensor

Mukufuna thandizo lina ndi code P2237?

Ngati mukufunabe thandizo ndi DTC P2237, 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.
