Zithunzi za DTC0175

P0175 - Kuphatikiza wolemera kwambiri (Banki 2)

Kodi vuto la P0175 limatanthauza chiyani?

P0175 ikuwonetsa kuti gawo lowongolera injini (ECM) limazindikira mafuta ochulukirapo komanso oxygen yokwanira mu osakaniza amafuta a mpweya (afr). Khodi iyi idzakhazikitsa pamene ECM ikulephera kubweza kuchuluka kwa mpweya kapena mafuta ofunikira kuti abwezeretse chiŵerengero cha mpweya wa mpweya ku magawo omwe atchulidwa.

Kwa injini zamafuta, chiŵerengero chochepa kwambiri cha mafuta ndi 14,7: 1, kapena 14,7 mbali za mpweya ndi gawo limodzi la mafuta. chiŵerengero ichi komanso amalenga pazipita kuchuluka kwa mphamvu mu kuyaka ndondomeko.

Njira yoyaka moto ndiyosavuta koma yosalimba. Magalimoto ambiri amakhala ndi zipinda zinayi mpaka zisanu ndi zitatu zoyaka moto mkati mwa injini. mpweya, mafuta, ndi spark zimakakamizika kulowa m'zipinda zoyaka, zomwe zimapangitsa "kuphulika" (komwe kumadziwika kuti kuyaka). spark imaperekedwa kuchipinda chilichonse choyaka nanosekondi imodzi pambuyo poti mpweya ndi mafuta zifika kuchipinda ndikuziyatsa. chipinda chilichonse choyaka chili ndi pisitoni; Pistoni iliyonse imayendetsedwa ndi kuyaka pa liwiro lalikulu komanso nthawi zosiyanasiyana.

kusiyana kwa nthawi ya pistoni iliyonse kumatsimikiziridwa ndi chiŵerengero cha mpweya-mafuta ndi nthawi ya injini. pisitoni ikapita pansi, iyenera kubwereranso kuti iyambe kuyaka. pisitoni imasuntha pang'onopang'ono kumbuyo nthawi iliyonse yomwe silinda ina imagwiritsa ntchito njira yake yoyaka moto, chifukwa zonse zimagwirizanitsidwa ndi msonkhano wozungulira wotchedwa crankshaft. zili ngati kugwedeza; nthawi iliyonse, pisitoni imodzi ikukwera mmwamba, ina ili pachimake, ndipo pisitoni yachitatu ikusunthira pansi.

ngati chilichonse munjirayi sichikuyenda bwino, zida zamkati za injiniyo zizigwira ntchito molimbika ndikugwirana wina ndi mzake, kapena injiniyo singayambe konse. Pankhani ya code P0175, padzakhala kuwonjezeka kwa mtunda wa gasi chifukwa ECM yazindikira kuti gasi wochuluka akugwiritsidwa ntchito.

Kachidindo kavuto kameneka (dtc) ndi kachidindo ka generic, kutanthauza kuti imagwira ntchito pamagalimoto okhala ndi obd-ii. Ngakhale zachilendo, njira zokonzetsera zitha kusiyanasiyana kutengera kupanga/chitsanzo. Izi zikutanthauza kuti sensa ya okosijeni mu banki 2 yazindikira kuti pali malo olemera (oxygen wocheperako pakutha). pa injini v6/v8/v10, banki 2 ndi mbali ya injini kuti alibe # 1 yamphamvu. Zindikirani. Khodi yamavutoyi ndi yofanana kwambiri ndi nambala ya P0172, ndipo kwenikweni, galimoto yanu imatha kuwonetsa ma code onse nthawi imodzi.

Chithunzi cha P0175 Nissan

Kupyolera mu kudziphunzira, chiŵerengero chenicheni cha mpweya / mafuta osakaniza chikhoza kukhala pafupi ndi chiŵerengero cha chiphunzitso chozikidwa pa mayankho ochokera ku masensa otentha a okosijeni. Engine Control Module (ECM) imawerengera chipukuta misozi ichi kuti ikonze kusiyana pakati pa zosakaniza zenizeni ndi zongoyerekeza. Ngati malipirowo ali okwera kwambiri, kusonyeza kusakwanira kwa chiŵerengero chosakanikirana, ECM imatanthauzira izi ngati kusokonezeka kwa dongosolo la jekeseni wa mafuta ndikuyambitsa Chizindikiritso cha Malfunction Indicator (MIL) pambuyo podutsa ndondomeko yowunikira maulendo awiri.

Zizindikiro za DTC P0175

Mwinamwake simudzawona zovuta zilizonse zogwirira ntchito, koma zizindikiro zotsatirazi zikhoza kuchitika:

• Kuchuluka kwamafuta.
• Kukhalapo kwa mwaye kapena madipoziti wakuda mu dongosolo utsi.
• Chongani "Check Engine" chizindikiro pa gulu chida.
• Pakhoza kukhala fungo lamphamvu lotopetsa.

Zomwe Zimayambitsa DTC P0175

Khodi ya P0175 itha kutanthauza kuti chimodzi kapena zingapo mwazimene zachitika:

• Sensor ya mass air flow (MAF) ndi yakuda kapena yolakwika, mwina chifukwa chogwiritsa ntchito zosefera za "lubricated".
• Vuto la vacuum.
• Mavuto ndi kuthamanga kapena mafuta.
• Sensa yotenthetsera yakutsogolo ya okosijeni ndiyolakwika.
• Kuyatsa molakwika.
• Majekeseni amafuta olakwika.
• Injector yamafuta imakhala yotsekeka, yotsekeka kapena ikutha.
• Chowongolera mafuta ndi cholakwika.
• Sensa yakuda kapena yolakwika ya air flow sensor.
• Sensa yoziziritsa yolakwika yolakwika.
• Thermostat yolakwika.
• ECM imafuna kukonzanso.
• Sensa ya oxygen yonyansa kapena yolakwika.
• Vuto la vacuum.
• Vuto ndi kupezeka kwamafuta.
• Kuthamanga kwamafuta kolakwika.

Zolakwa za matenda

Chigawo chimatengedwa kuti ndichosavomerezeka popanda kutsimikiziridwa kudzera mu kuyesa.

Kodi vuto la P0175 ndi lalikulu bwanji?

Dongosolo lolemera kwambiri limatha kufupikitsa moyo wa chosinthira chothandizira ndikuwonjezera kugwiritsa ntchito mafuta, zomwe zitha kukhala zokwera mtengo.

Mpweya woponderezedwa wolakwika ukhoza kuchititsa kuti injini iyambe kugwira ntchito kwambiri komanso kutulutsa mpweya wambiri wa zinthu zoipa.

Ndi kukonza kotani komwe kungathetse vuto la P0175?

Njira zomwe zingatheke ndi monga:

1. Yang'anani ma payipi onse a vacuum ndi PCV ndikusintha ngati kuli kofunikira.
2. Yeretsani mphamvu ya mpweya wotuluka. Ngati mukufuna thandizo, onani bukhu lanu la mautumiki la komwe lili. Poyeretsa, tikulimbikitsidwa kugwiritsa ntchito zotsukira zamagetsi kapena zotsuka mabuleki. Onetsetsani kuti sensa ndiyouma kwathunthu musanayikhazikitsenso.
3. Yang'anani mizere yamafuta ming'alu, potuluka, kapena pini.
4. Yang'anani kuthamanga kwa mafuta mu njanji yamafuta.
5. Yang'anani momwe zilili ndipo, ngati kuli kofunikira, yeretsani majekeseni amafuta. Mutha kugwiritsa ntchito chotsuka chojambulira mafuta kapena kulumikizana ndi akatswiri kuti muyeretse / kusintha.
6. Yang'anani kutulutsa kwa mpweya kumtunda kwa sensa yoyamba ya okosijeni (ngakhale izi ndizosayembekezereka za vuto).
7. Bwezerani mizere yong'ambika kapena yosweka.
8. Yeretsani kapena kusintha masensa okosijeni.
9. Yeretsani kapena sinthani sensor ya air flow.
10. Konzaninso ECM (module yowongolera injini) ngati kuli kofunikira.
11. Bwezerani pampu yamafuta.
12. Bwezerani zosefera mafuta.
13. Bwezerani mafuta owonongeka kapena otsina.
14. Bwezerani majekeseni amafuta olakwika.
15. Bwezerani chopumira chokhazikika.

Ndemanga zowonjezera

Onani ngati zoziziritsira zagalimoto yanu zikuyenda bwino. Kugwira ntchito molakwika kwa makina ozizira kumatha kusokoneza magwiridwe antchito a injini. Izi ndichifukwa choti ECM imakonzedwa kuti igwire ntchito bwino pakatentha kwambiri pamasiku ozizira, zomwe zimathandiza injini kutentha mwachangu. Ngati sensa yoziziritsa kuzizira ili yolakwika kapena chotenthetsera chakakamira, galimotoyo ikhoza kusafika kutentha komwe kumafuna, zomwe zimapangitsa kuti pakhale kusakaniza kolemera kosalekeza.
