P2196 O2 Sensor Signal Code Bias / Stuck Rich (Bank 1 SENSOR 1)

Khodi Yovuta ya OBD-II - P2196 - Kufotokozera Zaukadaulo

Chizindikiro cha sensor cha A / F O2 chotsalira / chokhazikika munthawi yopindulitsa (block 1, sensor 1)

Kodi vuto la P2196 limatanthauza chiyani?

Nambala iyi ndi nambala yofalitsira. Imawerengedwa kuti ndiyaponseponse momwe imagwirira ntchito popanga mitundu yonse yamagalimoto (1996 ndi atsopano), ngakhale njira zowongolera zingasiyane pang'ono kutengera mtunduwo.

Pamagalimoto ena ngati Toyota, izi zimatanthawuza masensa a A / F, masensa owerengera mpweya / mafuta. M'malo mwake, awa ndi masensa okhudzidwa kwambiri a oxygen.

Modulerain control module (PCM) imayang'anira kuchuluka kwa mpweya / mafuta pogwiritsa ntchito masensa a oksijeni (O2) ndikuyesera kukhala ndi chiŵerengero chabwinobwino cha mpweya / mafuta cha 14.7: 1 kudzera pamafuta. Chojambulira cha Oxygen A / F chimapereka kuwerengera kwamagetsi komwe PCM imagwiritsa ntchito. DTC iyi imayika pomwe kuchuluka kwa mpweya / mafuta kumawerengedwa ndi PCM kupatuka pa 14.7: 1 kuti PCM isakonzenso.

Khodi iyi imatanthawuza makamaka sensor pakati pa injini ndi chosinthira chothandizira (osati kumbuyo kwake). Bank #1 ndi mbali ya injini yomwe ili ndi silinda #1.

Chidziwitso: DTC iyi ndiyofanana kwambiri ndi P2195, P2197, P2198. Ngati muli ndi ma DTC angapo, nthawi zonse muziwongolera momwe amawonekera.

Zizindikiro

Pa DTC iyi, Nyali Yoyang'anira Chizindikiro (MIL) idzawala. Pakhoza kukhala zizindikilo zina.

Zomwe zimayambitsa zolakwika З2196

Khodi iyi imayikidwa chifukwa mafuta ochulukirapo akulowetsedwa muchipinda choyaka. Izi zitha kupangidwa ndi zovuta zosiyanasiyana.

Diphragm ECT (kutentha kozizira kwa injini) mphamvu yothamanga kwambiri yamafuta Mawaya owonongeka a ECT Anatsekera jekeseni wamafuta kapena PCM (Powertrain Control Module)

Zomwe zingayambitse kachidindo ka P2196 ndi izi:

• Chosavomerezeka cha oxygen (O2) kapena chiŵerengero cha A / F kapena chotenthetsera sensa
• Tsegulani kapena zazifupi mu dera la sensor la O2 (wiring, harness)
• Kuthamanga kwa mafuta kapena vuto la jakisoni wamafuta
• PCM yolakwika
• Kulowetsa mpweya kapena zingalowe m'malo mwa injini
• Ma injini operewera
• Mafuta kuthamanga kwambiri kapena otsika kwambiri
• Kutayikira / kulephera kwa dongosolo la PCV
• A / F kachipangizo kulandirana zosalongosoka
• Kulephera kwa MAF sensor
• Chojambula cha ECT chosagwira bwino
• Kuletsa kudya
• Mafuta kuthamanga kwambiri
• Mafuta kukanika kachipangizo wonongeka
• Mafuta mavuto kuthamanga yolephera
• Chonde dziwani kuti pamagalimoto ena omwe asinthidwa, nambala iyi imatha kubwera chifukwa cha zosintha (mwachitsanzo, dongosolo lotulutsa, manifolds, ndi zina zambiri).

Njira zowunikira ndi njira zothetsera mavuto

Gwiritsani ntchito chida chojambulira kuti muwerenge kuwerenga kwa sensa ndikuwunika mitengo yaying'ono komanso yayitali yayitali ndi sensa ya O2 kapena kuwerengera kwa chiwonetsero cha mafuta. Komanso, yang'anani pazithunzi zoyimitsa kuti muwone momwe zakhalira mukakhazikitsa code. Izi ziyenera kuthandizira kudziwa ngati sensa ya O2 AF ikugwira bwino ntchito. Yerekezerani ndi zomwe opanga amapanga.

Ngati mulibe chida chofufuzira, mutha kugwiritsa ntchito multimeter ndikuyang'ana zikhomo pa cholumikizira cha O2 sensor. Fufuzani zazifupi pansi, zopanda mphamvu, zotseguka, ndi zina. Yerekezerani magwiridwe antchito ndi mafotokozedwe aopanga.

Yang'anani mwamphamvu zingwe zolumikizira ndi zolumikizira zomwe zikupita ku sensa, yang'anani zolumikizira zosasunthika, ma scuffs / scuffs, mawaya osungunuka, ndi zina. Konzani ngati kuli kofunikira.

Yang'anani m'mizere yopumira. Muthanso kuyang'anitsitsa kutuluka kolowera pogwiritsa ntchito gasi wa propane kapena chotsukira mafuta pamphepete mwa ma injini pomwe injini ikuyenda, ngati rpm isintha, mwina mwapeza kutayikira. Samalani kwambiri pochita izi ndipo sungani chozimitsira moto pakagwa vuto. Ngati vutoli latsimikizika kuti limangotulutsa, kungakhale kwanzeru kusinthitsa mizere yonse yazitsulo ngati atakalamba, atakhala olimba, ndi zina zambiri.

Gwiritsani ntchito digito volt ohm mita (DVOM) kuti muwone ngati masensa ena omwe atchulidwa akugwira ntchito bwino, monga MAF, IAT.

Yesani kuyesa kuyesa mafuta, yang'anani kuwerenga motsutsana ndi zomwe wopanga adachita.

Ngati muli ndi bajeti yolimba ndipo muli ndi injini yokhala ndi banki zoposa imodzi ndipo banki imodzi yokha ndiye ili ndi vuto, mutha kusinthana ndi gauge kuchokera ku banki kupita ku ina, kuchotsa nambalayo, ndikuwona ngati nambala yake ikulemekezedwa. kupita tsidya lina. Izi zikuwonetsa kuti sensa / chowotcha chokha ndicholakwika.

Fufuzani galimoto yanu yaposachedwa ya Technical Service Bulletins (TSB), nthawi zina PCM ikhoza kusinthidwa kuti ikonze izi (ngakhale iyi si yankho wamba). Ma TSB angafunenso m'malo mwa sensa.

Mukamachotsa masensa a oxygen / AF, onetsetsani kuti mukugwiritsa ntchito zabwino. Nthawi zambiri, masensa a gulu lachitatu amakhala otsika ndipo sagwira ntchito momwe amayembekezera. Tikukulimbikitsani kuti mugwiritse ntchito m'malo mwaopanga zida zoyambirirazo.

Zolakwa Zomwe Zimachitika Mukamazindikira Khodi P2196

Cholakwika chofala kwambiri ndikusintha sensa ya O2 mutatha kuyang'ana kachidindo ndikunyalanyaza kuyesa kulikonse kuti mutsimikizire kuti O2 ndi yolakwika. Zolephera zonse zomwe zalembedwa pansipa zipanga izi ndi sensa ya O2 ndipo nthawi iyenera kugwiritsidwa ntchito kudzipatula.

Kuphatikiza pakusintha sensa ya O2 mwachangu, vuto lofananalo limachitika pamene katswiri amatanthauzira deta ya scanner mwachangu kwambiri. Nthawi zambiri izi zimakhala zosavuta kudziwa. Moti kusintha zida zomwe zimalephera nthawi zambiri pamagalimoto ena kumakhala kofala. Magalimoto onse ali ndi zomwe akatswiri amazitcha kulephera kwapateni. Tikayamba kuzindikira machitidwewa, ndizosavuta kuiwala kuti zolakwika zina zimatha kupanga code yotere. Izi zikachitika, kuchitapo kanthu mopupuluma kumabweretsa kusinthidwa kwa magawo olakwika, zomwe zimapangitsa kuti ndalama zokonzanso zichuluke kapena kuwononga nthawi kwa katswiri.

Kodi P2196 ndi yowopsa bwanji?

Choyipa kwambiri chomwe chingachitike chifukwa chogwira ntchito molemera ndikuthekera kwa chosinthira chothandizira kuyatsa moto. Ndizosowa, koma zotheka. Kuonjezera mafuta owonjezera pa chosinthira chothandizira kuli ngati kuponya nkhuni pamoto. Ngati vutoli lilipo, kuwala kwanu kwa Check Engine kudzawala mofulumira. Ngati muyang'ana kuwala kwa injini ya Check Injini, mungakhale pachiwopsezo chowotcha moto.

Ngati kuwala kwanu kwa Check Engine kumakhala koyaka nthawi zonse ndipo sikukuthwanima, ndiye kuti code iyi ndi yayikulu monga momwe galimoto yanu ikuyenda bwino. Muzovuta kwambiri, izi zitha kugwira ntchito mwankhanza komanso mwachiwonekere. Zabwino kwambiri, mudzakhala ndi mafuta osakwanira.

Ndi kukonza kotani komwe kungakonze P2196?

• mafuta pressure regulator m'malo
• Mass Air Flow (MAF) Sensor Replacement
• Kusintha sensa ya ECT (kutentha kozizira injini madzi)
• Kukonza mawaya owonongeka ku ECT
• Bwezerani jekeseni wamafuta omwe akuchucha kapena omata kapena majekeseni.
• O2 sensor m'malo
• Onerani. M'malo kuthetheka pulagi , mawaya a spark plug, kapu ndi rotor , chipika kapena kuyatsa mawaya.

Ndemanga zowonjezera zomwe muyenera kuziganizira ponena za code P2196

Kulakwitsa kofala ndiko kuganiza kuti kusakaniza kolemera ndi zotsatira za kubaya mafuta ochulukirapo mu injini. Lingaliro lolondola kwambiri ndiloti pali mafuta ochulukirapo poyerekeza ndi mpweya. Chifukwa chake akuti chiŵerengero chamafuta a mpweya. Nthawi zonse mukazindikira khodi yotere, ndikofunikira kwambiri kukumbukira izi nthawi zonse. Ndizofala kwambiri kukhala ndi gawo loyipa loyatsira kapena kusakhalapo mu silinda, koma PCM ikulamulabe mafuta ku jekeseni. Izi zipangitsa kuti mafuta osayaka alowe mu chitoliro chotulutsa mpweya. Tsopano chiŵerengero cha pakati pa mpweya ndi mafuta mu dongosolo la mpweya wasintha ndipo O2 amatanthauzira izi ngati mpweya wochepa, umene PCM imatanthauzira ngati mafuta ambiri. Ngati sensa ya O2 ikuwona mpweya wochuluka pakutha, PCM imatanthauzira izi ngati mafuta osakwanira kapena mafuta ochepa.

Momwe Mungakonzere P2196 Engine Code mu Mphindi 5 [Njira 4 za DIY / $8.78 Yokha]

Mukufuna thandizo lina ndi nambala yanu ya p2196?

Ngati mukufunabe thandizo ndi DTC P2196, 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.
