Ingcindezi ye-P0129 Barometric iphansi kakhulu

I-P0129 - I-OBD-II Ikhodi Yenkinga Incazelo Yobuchwepheshe

Umfutho womkhathi uphansi kakhulu

Uma kukhulunywa ngekhodi yezinkinga P0129, ingcindezi ye-barometric idlala indima ebalulekile. Umfutho womoya ophansi ungaba ukukhathazeka, ikakhulukazi lapho uhamba ezindaweni eziphakeme. Ingabe ukuqaphelile lokhu ngobude obujwayelekile? Kwenzekani uma lokhu kwenzeka? Ungaziqeda kanjani izimpawu? Thola konke odinga ukukwazi mayelana nekhodi ye-P0129.

Isho ukuthini ikhodi yenkinga P0129?

U-“P” wokuqala kukhodi yenkinga yokuxilonga (i-DTC) ikhombisa isistimu lapho ikhodi esebenza khona. Kulokhu, isistimu yokudlulisela (injini nokudlulisa). Uhlamvu lwesibili oluthi “0” lubonisa ukuthi lena yikhodi evamile yenkinga ye-OBD-II (OBD2). Uhlamvu lwesithathu "1" lubonisa ukungasebenzi kahle kwesistimu yokulinganisa uphethiloli nomoya, kanye nesistimu yokulawula ukungcola. Izinhlamvu ezimbili zokugcina "29" zimelela inombolo ethile ye-DTC.

Ikhodi yephutha engu-P0129 isho ukuthi ingcindezi ye-barometric iphansi kakhulu. Lokhu kwenzeka lapho i-powertrain control module (PCM) ithola ingcindezi engaphansi kwenani elimisiwe lomkhiqizi. Ngamanye amazwi, ikhodi ye-P0129 yenzeka lapho inzwa yokucindezela komoya (MAP) noma i-barometric air pressure (BAP) inzwa inephutha.

Ibucayi kangakanani ikhodi P0129?

Lolu daba alubucayi okwamanje. Nokho, kubalulekile ukuhlola njalo ukuthi kusesikhathini futhi ukulungise kusenesikhathi ukuze ugweme izinkinga ezinkulu.

*Imoto ngayinye ihlukile. Izici ezisekelwa uCarly ziyahlukahluka ngemodeli yemoto, unyaka, ihadiwe, nesoftware. Xhuma isithwebuli embobeni ye-OBD2, xhuma kuhlelo lokusebenza, yenza ukuxilonga kokuqala futhi uhlole ukuthi imiphi imisebenzi etholakalayo yemoto yakho. Sicela futhi uqaphele ukuthi ulwazi olunikezwe kulesi sizindalwazi ngelezinjongo zolwazi kuphela futhi kufanele lusetshenziswe ngokuzifaka wena engozini. I-Mycarly.com ayinasibopho samaphutha noma ukweqiwa noma ngemiphumela etholwe ngokusebenzisa lolu lwazi.

Njengoba le nkinga ingenza injini ingashi futhi ikhiphe amagesi ngaphakathi emotweni, kubalulekile ukuyilungisa ngokushesha lapho kuvela lezi zimpawu ezingenhla.

Yiziphi izimpawu zekhodi P0129

Ungasola leli khodi lephutha uma ubona izimpawu ezilandelayo:

1. Hlola ukuthi ilambu lenjini livuliwe yini.
2. Ukusetshenziswa kukaphethiloli kuphezulu kakhulu.
3. Ukusebenza kahle kwenjini.
4. Injini ayisebenzi kahle.
5. Ukushintshashintsha kokusebenza kwenjini ngesikhathi sokusheshisa.
6. I exhaust ikhipha intuthu emnyama.

Izizathu zekhodi P0129

Izimbangela ezingaba khona zale khodi zihlanganisa:

1. Indawo yesixhumi senzwa ye-MAF/BPS egqwalile.
2. Isikhala senjini esinganele ngenxa yokuguga kwenjini, ukungasebenzi kabi noma isiguquli se-catalytic esivalekile.
3. I-BPS enephutha (inzwa yokucindezela komoya eningi).
4. I-MAP evuliwe noma efushanisiwe kanye/noma izintambo zenzwa ye-BPS.
5. Ukumiswa kwesistimu okunganele ku-MAF/BPS.
6. I-PCM enephutha (imojuli yokulawula injini) noma iphutha lokuhlela le-PCM.
7. Ukungasebenzi kahle kwenzwa yomfutho womoya ohlukahlukene.
8. Inzwa ye-barometric air pressure inephutha.
9. Izinkinga ngezintambo noma izixhumi.
10. Ukugqwala endaweni yesixhumi yanoma yiziphi izinzwa.
11. Isiguquli se-catalytic esivaliwe.
12. Ukushoda kokumiswa kwesistimu kuzinzwa.

Inzwa ye-PCM ne-BAP

Umfutho we-atmospheric uyahluka ngokulingana nokuphakama ngaphezu kwezinga lolwandle. Inzwa ye-barometric air pressure (BAP) idlala indima ebalulekile ekuvumeleni imojula yokulawula injini (PCM) ukuthi iqaphe lezi zinguquko. I-PCM isebenzisa ulwazi oluvela ku-BAP ukuze ilawule inani likaphethiloli olethwayo nokuthi injini iqala nini.

Ngaphezu kwalokho, i-voltage eyireferensi, indawo yebhethri, kanye nesekhethi yesignali ephumayo eyodwa noma ngaphezulu kuhanjiswa kunzwa yokucindezela kwe-barometric. I-BAP ilungisa isifunda sereferensi ye-voltage futhi ishintsha ukumelana ngokuvumelana nengcindezi yamanje ye-barometric.

Uma imoto yakho isendaweni ephakeme, ingcindezi ye-barometric ishintsha ngokuzenzakalelayo ngakho-ke amazinga okumelana nokushintsha kwe-BAP, okuthinta i-voltage ethunyelwa ku-PCM. Uma i-PCM ithola ukuthi isignali kagesi evela ku-BAP iphansi kakhulu, izobangela ukuthi ikhodi ye-P0129 ivele.

Ungaxilonga futhi ulungise kanjani ikhodi ye-P0129?

Isixazululo sekhodi ye-P0129 singahluka kakhulu kuye ngomkhiqizi wemoto, njengoba ukucaciswa kwezinzwa ze-BAP ne-MAP kungahluka kakhulu. Isibonelo, izindlela zokuxazulula inkinga ze-P0129 ku-Hyundai zingase zingafaneli i-Lexus.

Ukuze uhlole ngempumelelo iphutha, uzodinga isithwebuli, i-digital volt/ohmmeter kanye ne-vacuum gauge. Ukulandela lezi zinyathelo kuzokusiza ukuthi uhlole futhi unqume izinqubo zokulungisa ezidingekayo:

1. Qala ngokuhlola okubonakalayo ukuze ubone izintambo ezilimele nezixhumi. Noma yimuphi umonakalo otholakele kufanele ulungiswe ngaphambi kokuxilongwa okwengeziwe.
2. Njengoba i-voltage yebhethri ephansi ingabangela i-P0129, hlola umthamo webhethri nesimo sokugcina.
3. Bhala phansi wonke amakhodi ukuze uqinisekise ukuthi inkinga ikuzinzwa ezishiwo kanye nohlelo, uqede ezinye izinkinga ezingaba khona.
4. Yenza ukuhlola kwe-vacuum yenjini. Khumbula ukuthi izinkinga zangaphambilini zokudonsa amanzi enjini njengeziguquli ze-catalytic ezibambekile, amasistimu e-exhaust avimbelayo, nomfutho ophansi kaphethiloli nakho kungathinta i-vacuum yenjini.
5. Uma zonke izinzwa namasekhethi kungaphakathi kokucaciswa komkhiqizi, sola isofthiwe ye-PCM noma ye-PCM engalungile.
6. Noma yimuphi umonakalo otholakala kuzintambo nezixhumi kufanele ulungiswe.

Ukulandela lezi zinyathelo kuzokusiza ukuthi uhlole ngempumelelo futhi uxazulule inkinga yekhodi yephutha engu-P0129 emotweni yakho.

Kubiza malini ukulungisa ikhodi P0129?

Ukuhlonza ikhodi yephutha ye-P0129 kungaba inqubo edla isikhathi futhi ngokuvamile kubiza phakathi kwama-euro angu-75 no-150 ngehora. Kodwa-ke, izindleko zabasebenzi zingahluka kuye ngendawo kanye nokwakhiwa kwemoto yakho.

Ungakwazi yini ukuzilungisela ikhodi?

Kuhlale kungcono ukufuna usizo lochwepheshe njengoba ukuxazulula inkinga kudinga izinga elithile lolwazi lobuchwepheshe. Lokhu kungenxa yokuthi ikhodi yephutha kwesinye isikhathi ihambisana namanye amakhodi amaningi ezinkinga. Kodwa-ke, uma uhlangabezana nanoma yiziphi izimpawu, ungahlala uxilongwa futhi ufune usizo kusenesikhathi.
