P0175 OBD-II Dambudziko Kodhi: Kupisa Kwakanyanya Kupfuma (Bhengi 2)

Nhoroondo ye DTC P0175

P0175 - Musanganiswa wakapfuma zvakanyanya (Bhangi 2)

Ko dambudziko rekodhi P0175 rinorevei?

P0175 inoratidza kuti injini yekudzora module (ECM) inoona yakawandisa mafuta uye isina kukwana oksijeni mumhepo-mafuta musanganiswa (afr). Iyi kodhi ichaisa kana ECM isingakwanisi kubhadhara huwandu hwemhepo kana mafuta anodiwa kudzorera chiyero chemhepo-mafuta kune zvakatarwa parameters.

Kune injini dzepeturu, iyo yakanyanya hupfumi hwehutsi reshiyo ndeye 14,7: 1, kana 14,7 zvikamu zvemhepo kusvika 1 chikamu chemafuta. chiyero ichi chinogadzirawo huwandu hwakawanda hwesimba mukupisa.

Maitiro ekupisa ari nyore asi asina kusimba. Motokari dzakawanda dzine makamuri mana kusvika masere ekupisa mukati mejini. mhepo, mafuta, uye spark zvinomanikidzwa kupinda mumakamuri ekupisa, zvichiita "kuputika" (kunonyanya kuzivikanwa sekupisa). spark inopihwa kukamuri yega yega yekupisa imwe nanosecond mushure mekunge mhepo nemafuta zvasvika mukamuri nekuibatidza. imwe neimwe kamuri inopisa ine piston; Imwe neimwe piston inofambiswa nekupiswa nekumhanya kwakanyanya uye panguva dzakasiyana.

mutsauko wenguva yepiston imwe neimwe inotarirwa nemhepo-mafuta reshiyo uye injini nguva. kana piston yadzika pasi, inofanira kudzoka kune imwe nzira yekupisa. iyo piston inofamba zvishoma nezvishoma ichidzokera shure nguva imwe neimwe apo imwe yemamwe masilinda inopinda maitiro ayo ekupisa, sezvo ose akabatanidzwa kumusangano unotenderera unozivikanwa se crankshaft. inenge yakaita sejuggling effect; chero nguva, piston imwe iri kusimuka, imwe iri pamusoro, uye yechitatu pisitoni iri kufamba ichidzika.

kana chimwe chinhu chiri muchiitiko ichi chikatadza, zvikamu zvemukati zveinjini zvichashanda nesimba uye kushanda kune mumwe nemumwe, kana injini inogona kusatanga zvachose. Panyaya yekodhi P0175, panogona kuwedzera gasi mileage nekuti ECM yaona kuti gasi rakawandisa riri kushandiswa.

Iyi diagnostic dambudziko kodhi (dtc) ndeye generic transmission code, zvinoreva kuti inoshanda kune obd-ii ine mota dzakashongedzerwa. Kunyangwe zvakajairika, matanho ekugadzirisa chaiwo anogona kusiyana zvichienderana nekugadzira / modhi. Izvi zvinoreva kuti sensor yeokisijeni mubhangi 2 yaona mamiriro akapfuma (okisijeni yakawandisa mukupeta). pamusoro v6/v8/v10 injini, bhangi 2 ndiro divi injini kuti haana #1 humburumbira. note. Iyi kodhi yedambudziko yakafanana neiyo P0172 kodhi, uye kutaura zvazviri, mota yako inogona kuratidza ese macode panguva imwe chete.

Kuburikidza nekuzvidzidzira, iyo chaiyo yemhepo / mafuta musanganiswa reshiyo inogona kuswedera kune theoretical reshiyo inoenderana nemhinduro kubva kune inopisa okisijeni sensors. Iyo Engine Control Module (ECM) inoverengera muripo uyu kugadzirisa musiyano uripo pakati peiyo chaiyo uye theoretical musanganiswa ratios. Kana muripo wacho wakanyanya kukwirisa, zvichiratidza kusakwana kwemusanganiswa ratio, iyo ECM inodudzira izvi semafuta jekiseni system kusashanda uye inomisa iyo Malfunction Indicator Indicator (MIL) mushure mekupfuura iyo diagnostic logic kwenzendo mbiri.

Zviratidzo zveDTC P0175

Iwe haugone kuona chero akakosha ekubata matambudziko, asi zvinotevera zviratidzo zvinogona kuitika:

• Kuwedzera kwemafuta.
• Kuvapo kwe soot kana dema deposits mu exhaust system.
• Tarisa iyo "Check Injini" chiratidzo pane chiridzwa pane.
• Panogona kuva nekunhuhwirira kwakasimba kwemhepo.

Zvikonzero zveDTC P0175

Iyo P0175 kodhi inogona kureva kuti chimwe kana zvimwe zvezviitiko zvinotevera zvaitika:

• Iyo mass air flow (MAF) sensor ine tsvina kana kukanganisa, zvichida nekuda kwekushandiswa kwe "lubricated" mafirita emhepo.
• Vacuum leak.
• Matambudziko nekumanikidzwa kana mafuta ekupa.
• Iyo inopisa pamberi peokisijeni sensor yakashata.
• Kubatidza kusina kunaka.
• Majekiseni emafuta asina kunaka.
• Injector yemafuta yakavharwa, yakavharwa kana kubuda.
• Iyo mafuta regulator yakashata.
• Tsvina kana kukanganisa mass air flow sensor.
• Iyo inotonhorera tembiricha sensor haina kukwana.
• Thermostat yakanganisa.
• Iyo ECM inoda reprogramming.
• Tsvina kana kukanganisa oxygen sensor.
• Vacuum leak.
• Dambudziko nemafuta ekufambisa.
• Mafuta emafuta asina kunaka.

Maitiro ekuongorora

• Tarisa mafuta ekumanikidza.
• Ongorora majekiseni emafuta kune zvirambidzo.
• Tarisa mafuta injector pulse.
• Ongorora mitsetse yemafuta yepini uye yakatsemuka.
• Ongorora mitsetse yese yekutsvaira kuti uone kutsemuka kana kukanganisa.
• Ongorora ma sensors eokisijeni.
• Shandisa scan tool kuyera injini tembiricha, wozoenzanisa zvabuda neiyo infrared thermometer.

Zvikanganiso zvekuongorora

Yakakomba sei dambudziko rekodhi P0175?

Sisitimu inomhanya zvakanyanya inogona kupfupisa hupenyu hweinoshandura inoshandura uye kuwedzera kushandiswa kwemafuta, izvo zvinogona kudhura.

Iyo isiriyo yakamanikidzwa mhepo reshiyo inogona kukonzera inorema injini kushanda uye kuwedzera kuburitswa kwezvinhu zvinokuvadza.

Ndedzipi kugadzirisa kuchagadzirisa iyo P0175 dambudziko kodhi?

Mishonga inobvira inosanganisira:

1. Ongorora ese vacuum uye PCV hose uye tsiva iwo kana zvichidikanwa.
2. Chenesa iyo mass air flow sensor. Kana uchida rubatsiro, tarisa bhuku rako rebasa renzvimbo yaro. Pakuchenesa, zvinokurudzirwa kushandisa electronic cleaner kana brake cleaner. Ita shuwa kuti sensor yacho yakaoma zvachose usati waidzosera kumashure.

4. Tarisa kudzvanywa kwemafuta munjanji yemafuta.
5. Tarisa mamiriro acho uye, kana zvichidikanwa, chenesa majekiseni emafuta. Unogona kushandisa jekiseni jekiseni remafuta kana kubata nyanzvi yekuchenesa/kutsiva.
6. Tarisa kuti kubuda kwemhepo kunodonha kumusoro kweiyo yekutanga okisijeni sensor (kunyangwe ichi chiri chikonzero chisingaite chedambudziko).
7. Tsiva mitsetse yakatsemuka kana yakatyoka.
8. Chenesa kana kutsiva okisijeni masensa.
9. Chenesa kana kutsiva iyo mass air flow sensor.
10. Dzokorora iyo ECM (injini yekudzora module) kana zvichidikanwa.
11. Tsiva pombi yemafuta.
12. Tsiva sefa yemafuta.
13. Tsiva tambo dzemafuta dzakakuvadzwa kana dzakapinwa.
14. Tsiva majekiseni emafuta asina kunaka.

Mamwe mashoko

Tarisa kana mota yako yekutonhodza system iri kushanda nemazvo. Kushanda zvisina kujairika kweiyo inotonhorera system kunogona kukanganisa kuita kweinjini. Izvi zvinodaro nekuti iyo ECM inorongedzerwa kuti ishande zvakanaka pakupisa kwakanyanya pamazuva anotonhora, izvo zvinobatsira injini kudziya nekukurumidza. Kana iyo inotonhorera tembiricha sensor inokanganisa kana thermostat yakamira, mota inogona kusasvika painoda tembiricha, zvichikonzera musanganiswa unogara wakapfuma.
