P0139 - HO2S Bank 1 Sensor 2 O1 Sensor Circuit Inononoka Mhinduro (B2SXNUMX)

P0139 - dambudziko kodhi tsananguro

Iyo inopisa okisijeni sensor 2 (ho2s), kuzasi kweiyo nzira nhatu inoshandura inoshandura (yakawanda), inotarisisa mwero weokisijeni mumagasi ekuburitsa ega rimwe nerimwe silinda. Kuti unyatsoita catalyst performance, the air to fuel reshiyo (air-fuel ratio) inofanira kuchengetedzwa padyo neakakodzera stoichiometric ratio. Iyo inobuda voltage yeho2s sensor inongoerekana yachinja padyo neiyo stoichiometric ratio.

Injini yekudzora module (ECM) inogadzirisa nguva yejekiseni remafuta kuitira kuti chiyero chemhepo-mafuta chinenge stoichiometric. Mukupindura kuvepo kweokisijeni mumagasi ekupedza, iyo ho2s sensor inogadzira voltage ye0,1 kusvika 0,9 V. kana iyo okisijeni yemukati yemhepo yekuburitsa gasi ichiwedzera, chiyero chemhepo-mafuta chinova chakaonda.

Iyo ECM module inodudzira musanganiswa wakaonda kana ho2s sensor voltage iri pasi pe0,45V. kana iyo okisijeni yemukati yemagasi ekuburitsa inoderera, chiyero chemhepo-mafuta chinova chakapfuma. Iyo ECM module inodudzira chiratidzo chakapfuma kana ho2s sensor voltage inodarika 0,45V.

Chii chinorehwa neDTC P0139?

Dambudziko rekodhi P0139 rinosanganiswa nedivi remutyairi rear oxygen sensor uye inoratidza kuti injini yemhepo-mafuta reshiyo haisi kugadziridzwa zvakanaka neokisijeni sensor kana ECM chiratidzo. Izvi zvinogona kuitika mushure mekunge injini yadziya kana injini isiri kushanda zvakanaka. "Bhangi 1" rinoreva bhangi remasilinda rine humburumbira #1.

Code P0139 yakajairika OBD-II chiyero uye inoratidza kuti bhangi 1 oxygen sensor, sensor 1, haina kuratidza kudonha kwevolti isingasviki 0,2 volts kwemasekonzi manomwe panguva yemafuta latch nguva. Iyi meseji inoratidza inononoka sensor mhinduro sezvakaonekwa neInjini Yekudzora Module (ECM).

Zvimwe zvinokonzera

Yekodhi P0139, iyo ECM inoderedza kupihwa kwemafuta kune injini panguva yekudzikira kweinjini uye ese maO2 sensors anofanirwa kupindura nemhepo inobuda isingasviki 2 V, zvichiratidza huwandu hweokisijeni mumagasi ekupedza. Kodhi yekukanganisa inoiswa kana iyo bhangi 2 O1 sensor, sensor 1, isingapindure kune mafuta akachekwa kwemasekonzi manomwe kana kupfuura.

Izvi zvinogona kukonzerwa

• mafuta akawandisa mukuyerera kwegasi nekuda kwekudonha kunogona kuitika mujekiseni remafuta,
• kusashanda kweiyo yekumashure inopisa okisijeni sensor, block 1,
• Rear inopisa oxygen sensor bank 1 wiring harness (yakavhurika kana ipfupi),
• matambudziko nekubatanidza kwemagetsi kweyekumashure kunopisa okisijeni wedunhu 1 bhatiri,
• mafuta asina kukwana,
• majekiseni emafuta asina kunaka,
• mhepo inodonha mukutora,
• kukanganisa muokisijeni sensor unit ine reverse kudziyisa,
• Rear inopisa oxygen sensor bank 1 wiring harness (yakavhurika kana ipfupi),
• kusashanda kwedunhu 1 rekumashure rinopisa okisijeni sensor,
• mafuta asina kukwana,
• akanganisa majekiseni emafuta uye zvinogona kuitika mukudonha kwemhepo inodonha,
• pamwe chete nekubuda kwegasi rinobuda.

Ndezvipi zviratidzo zveP0139 kodhi?

• Injini inogona kumira kana kuita kushata nekuda kwemafuta akawandisa.
• Injini inogona kuratidza kuzeza panguva yekumhanyisa mushure mekudzikisa.
• Cheki injini chiedza (kana injini yekugadzirisa chiedza) inouya.
• Kunyanya kushandiswa kwemafuta.
• Kuwedzeredza kuwanda kwehutsi mu exhaust system.

Nzira yekuongorora kodhi P0139?

1. Skena makodhi uye data rekodhi, kutora ruzivo kubva pafuremu.
2. Tarisa iyo O2 sensor kuverenga kuti uone kana iyo voltage inodonha pazasi 0,2 V panguva yekuderera.
3. Tarisa injini yehutsi kudzvinyirirwa kuti ibude muhuni injector system.
4. Ita shuwa kuti O2 sensor haina kusvibiswa nezvinhu zvekunze senge inotonhorera kana mafuta.
5. Ongorora iyo exhaust system yekukuvara kana matambudziko, kunyanya munzvimbo inoshandura inoshandura.
6. Ita bvunzo dzakapihwa nemugadziri kuti uwedzere kuongororwa.

Zvikanganiso zvekuongorora

Kuti udzivise kutadza kuongororwa, tevera mirairo iri nyore:

Kana masensa ese ari maviri (1 ne2) kudivi rimwe chete reinjini akanonoka kupindura, teerera kune inobvira injector yemafuta inodonha mubhangi rekutanga reinjini.

Iyi kodhi isati yaitika, gadzirisa chero matambudziko angangove neakanamatira throttle valve inogona kukanganisa maitiro ekuvhara mafuta.

Tarisa mamiriro eiyo catalytic inoshandura kukuvara kunogona kukonzera sensor kusashanda.

Yakakomba sei dambudziko rekodhi P0139?

Iyi kodhi inoratidza kuti kunyangwe iyo sensor yakanaka, injini inoramba ichiendesa mafuta panguva yekudzikisira, kunyangwe isingadiwe. Izvi zvinogona kukonzera kuwedzera kushandiswa kwemafuta uye kunyange injini kumira kana yakamira kana mafuta akawandisa ari kupinda mumasilinda.

Iyo ECM (injini yekudzora module) haikwanise kudzora kuvharwa kwemafuta kana majekiseni emafuta asina kuvharwa, izvo zvinogona kukonzera kunyanyisa kushandiswa kwemafuta.

Ndekupi kugadzirisa kuchagadzirisa kodhi P0139?

Kutsiviwa kweO2 sensor yebhangi 1 sensor 1 kunofanirwa kuitwa chete mushure mekunge mamwe ese mafuta uye exhaust system cheki yapera.

1. Chekutanga, tarisa mamiriro ehuturu system uye wotsiva jekiseni rinobvinza mafuta kana rawanikwa.
2. Dzorera iyo catalyst pamberi pe sensor kana ichikanganisa.
3. Usati watsiva iyo O2 sensor, chenesa majekiseni uye ita shuwa kuti chero kuvuza kwakagadziriswa.

Inononoka O2 sensor mhinduro inogona kunge iri nekuda kwekuchembera uye kusvibiswa. Sezvo iyo O2 sensor inoyera iyo okisijeni yemukati yemagasi ekupedza, chero madhipoziti kana kusvibisa pamusoro payo anogona kukanganisa kuyerwa kwakaringana. Mumamiriro ezvinhu akadaro, kuchenesa kana kutsiva sensor kunogona kubatsira kudzoreredza kushanda kwayo uye kugadzirisa mhinduro yayo kune shanduko mumagasi ekupedza.
