I-P0172 - Ikhodi yokuxilonga ixube kakhulu

29.08.2022 /

Incazelo yobuchwepheshe yekhodi yenkinga ye-OBD2 - P0172

Iphutha p0172 kusho ukuthi ingxube inothe kakhulu (noma isistimu inothe kakhulu). ngakho-ke, ingxube kaphethiloli ephinde yacetshiswa inikezwa kumasilinda omlilo. Njengekhodi P0171, iphutha lengxube elicebile liyiphutha lesistimu. Okusho ukuthi, akubonisi ukuhlukana okucacile kwezinzwa, kodwa imingcele yenani likaphethiloli idlula inani lomkhawulo.

Kuye ngesizathu esibangele ukuvela kwekhodi yephutha enjalo, ukuziphatha kwemoto nakho kuhlukile. Kwezinye izimo, kuzobonakala ukusetshenziswa kukaphethiloli, futhi kokunye, ukuminca kuphela uma ungenzi lutho noma isivinini sokubhukuda, kungaba ngenjini evuthayo yangaphakathi, noma lapho kubanda.

Izimo zephutha zokusayina

Injini yomlilo yangaphakathi kufanele iqalwe futhi ukunikezwa kukaphethiloli kwenzeka ngempendulo evela kunzwa ye-oxygen (i-lambda probe), kuyilapho lingekho iphutha elivela kunzwa epholile, inzwa yokushisa komoya yokungenisa, ukucindezela okuphelele (inzwa ye-MAP), i-DPRV, i-DPKV kanye inzwa yokuma kwe-throttle. Uma isamba esimaphakathi sezinqamuleli zikaphethiloli zesikhathi esifushane nezesikhathi eside singaphansi kwama-33% ngaphezudlwana kwemizuzu emi-3 esikhathini esiyi-7 sokuhlola. Isibani senkomba kuphaneli yensimbi sizocisha kuphela uma ukuxilonga kungaboni ukungasebenzi kahle ngemuva kwemijikelezo emithathu yokuhlola.

Izimpawu ze-P0172

  • Imililo eyenzeka njalo.
  • Ukusetshenziswa ngokweqile kukaphethiloli
  • Isibani senjini sivuliwe.
  • Lezi zimpawu ezijwayelekile kuphela ezingenzeka kwamanye amakhodi.

Izimbangela ezingenzeka zephutha p0172

Ikhodi Yenkinga Yokuxilonga (DTC) P0172 OBD II.

ukuze uqonde ukuthi yini eyabangela iphutha lengxube ecebile, udinga ukwenza uhlu lwezizathu zakho usebenzisa i-algorithm encane.

Ukunothiswa kwengxube kubonakala ngenxa yokuvutha okungaphelele (ukunikezwa ngokweqile noma ukuntuleka komoya):

  • lapho uphethiloli ungashi, khona-ke amakhandlela noma amakhoyili awasebenzi kahle;
  • uma inikezwa ngokweqile, inzwa ye-oxygen noma ama-injection yibo okumele basolwe;
  • akukho moya owanele - inzwa yokugeleza komoya inikeza idatha engalungile.

Uphethiloli oweqile akuvamile ukwenzeka, kodwa ukuntuleka komoya inkinga ejwayelekile. Ukunikezwa komoya kuphethiloli kwenzeka ebudlelwaneni phakathi kwenzwa ye-MAP kanye ne-lambda probe. Kodwa ngaphezu kwezinzwa, inkinga ingase futhi ibangelwa ukwephulwa kwezikhala ezishisayo (izinjini ezine-HBO), ukulimala komshini kuma-gaskets ahlukahlukene kanye nezimpawu, ukungasebenzi kahle ngesikhathi, noma ukucindezelwa okwanele.

ukuze ubhekane nayo yonke imithombo engaba khona eholele ekuhlulekeni, isheke lenziwa ngokwala maphuzu alandelayo:

  1. Hlaziya ulwazi oluvela kusithwebuli;
  2. Lingisa izimo zokwenzeka kwalokhu kwehluleka;
  3. Hlola izingxenye nezinhlelo (ukuba khona koxhumana nabo abahle, ukuntuleka kokumunca, ukusebenza), okungaholela ekubukeni kwephutha p0172.

Izindawo zokuhlola eziyinhloko

Ngokusekelwe kulokhu okungenhla, singanquma izizathu eziyinhloko:

  1. I-DMRV (imitha yokugeleza komoya), ukungcoliswa kwayo, ukulimala, ukulahleka kokuxhumana.
  2. Isihlungi somoya, esivalekile noma ukuvuza komoya.
  3. Inzwa ye-oxygen, ukusebenza kwayo okungalungile (ukonakala, ukulimala kwezintambo).
  4. I-valve ye-adsorber, ukusebenza kwayo okungalungile kuthinta ukubanjwa kwemfucumfucu kaphethiloli.
  5. Umfutho wesitimela samafutha. Ukucindezela ngokweqile, kungase kubangelwe isilawuli sengcindezi esinephutha, isistimu yokubuyisela uphethiloli eyonakele.

Ukuxazulula inkinga ingxube ye-P0172 inothe kakhulu

Ngakho-ke, ukuze uthole iyunithi enecala noma uhlelo, uzodinga ukuhlola i-MAF, DTOZH kanye nezinzwa ze-lambda probe nge-multimeter. Bese ubheka ama-spark plugs, izintambo namakhoyili. Linganisa umfutho kaphethiloli ngegeji yokucindezela. Hlola izimpawu zokuthungela. Futhi hlola i-air inlet bese ukhipha ukuxhumana okuphindaphindiwe kokuvuza komoya.

Ngemuva kokulungisa inkinga, uzodinga ukusetha kabusha isinqamuleli sikaphethiloli ukuze usethe kabusha ukunquma okude kube ngu-0%.

Ngemva kokulandela zonke izincomo, ngokuqinisekile uzokwazi ukubhekana nokusebenza okungalungile kwenjini yomlilo yangaphakathi kanye nokufakwa kwekhodi yephutha P0172 kokubili ku-VAZ nasezimotweni zangaphandle ezifana neToyota noma i-Mercedes, kanye nezinye izimoto ezine-electronics. izilawuli. Nakuba ngokuvamile akudingekile ukuqedela wonke amaphuzu, ezimweni eziningi ngokushayela noma ukufaka esikhundleni se-DMRV noma inzwa ye-oxygen.
