I-P0239 – i-turbocharger boost sensor B ukungasebenzi kahle kwesekethe

I-P0239 - incazelo yezobuchwepheshe yekhodi yephutha ye-OBD-II

I-Turbocharger Boost Sensor B Ukungasebenzi Kwesekethe

Isho ukuthini ikhodi P0239?

I-Code P0239 iyikhodi evamile ye-OBD-II eqalwa lapho I-Engine Control Module (ECM) ithola umehluko phakathi kwe-boost pressure sensor B kanye nokufundwa kwenzwa ye-pressure manifold (MAP) uma injini isebenza ngamandla amancane kanye nengcindezi ye-turbocharger kufanele. kube zero..

Lawa makhodi ajwayelekile kuzo zonke izinhlobo zezimoto, futhi akhombisa izinkinga nge-turbocharger boost pressure. Nokho, izinyathelo eziqondile zokuxilonga zingahluka kuye ngemodeli ethile yemoto.

Amakhodi e-OBD awabonisi iphutha elithile, kodwa asize uchwepheshe anqume indawo okufanele abheke kuyo imbangela yenkinga.

Ukushaja okuphezulu (ukungeniswa okuphoqelelwe) kuthuthukisa kanjani ukusebenza

Ama-Turbocharger aletha umoya omningi enjinini kunalokho injini ekwazi ukuwungenisa ngaphansi kwezimo ezijwayelekile. Ukwanda komthamo womoya ongenayo, kuhlanganiswe nophethiloli owengeziwe, kunomthelela ekwandeni kwamandla.

Ngokuvamile, i-turbocharger ingakhuphula amandla enjini ngamaphesenti angu-35 kuya kwangu-50, injini yakhelwe ngokukhethekile ukuphatha i-turbocharging. Izingxenye zenjini ezijwayelekile aziklanyelwe ukumelana nomthwalo okhiqizwa yilolu hlobo lomjovo womoya ophoqelelwe.

Ama-Turbocharger ahlinzeka ngokunyuka okukhulu kwamandla ngaphandle kokuthinta ukonga uphethiloli. Basebenzisa i-exhaust gas flow ukuze bacuphe i-turbo, ukuze ukwazi ukuyicabanga njengamandla engeziwe ngaphandle kwezindleko ezengeziwe. Kodwa-ke, bangahluleka ngokuzumayo ngenxa yezizathu ezihlukahlukene, ngakho-ke uma kunenkinga nge-turbocharger, kunconywa ukuyilungisa ngokushesha. Ngenjini ene-turbocharged, ukwehluleka kwe-turbocharger kungenza isimo sibe sibi kakhulu ngenxa yomthamo omkhulu womoya ocindezelwe.

Kubalulekile ukukhumbula ukuthi injini evamile ene-turbocharged akufanele iguqulwe ngokwandisa umfutho we-boost. Ukulethwa kukaphethiloli kanye namajika esikhathi ama-valve ezinjini eziningi awakuvumeli ukusebenza ngomfutho we-boost ophakeme, ongabangela ukulimala okukhulu kwenjini.

Qaphela: Le DTC icishe ifane ne-P0235, ehlotshaniswa ne-Turbo A.

Yiziphi izimpawu zekhodi yenkinga P0239?

Isibani se-Check Engine sikhanyisa uma i-DTC isetha. Imojuli ye-turbo ingase ikhutshazwe isilawuli senjini, okuholela ekulahlekelweni kwamandla ngesikhathi sokusheshisa.

Izimpawu zekhodi ye-P0239 zifaka:

1. Ikhodi ye-P0239 ikhombisa inkinga kusekethe yokulawula i-boost, okungenzeka ihambisane namakhodi engeziwe ahlobene nezingxenye ezithile zesekethe.
2. Ukulahlekelwa ukusheshisa kwenjini.
3. Izilinganiso ze-boost pressure zingase ziphume ebangeni: ngaphansi kwamaphawundi angu-9 noma ngaphezulu kwamaphawundi angu-14, okuyinto engavamile.
4. Imisindo engajwayelekile efana nokushaya ikhwela noma imisindo ekhencezayo evela ku-turbocharger noma amapayipi.
5. Ikhodi yenzwa engaba khona ekhombisa ukuqhunyiswa ngenxa yezinga lokushisa eliphezulu lekhanda lesilinda.
6. Ukulahlekelwa okujwayelekile kwamandla enjini.
7. Intuthu ephuma epayipini lokukhipha.
8. Amakhandlela angcolile.
9. Izinga lokushisa eliphezulu lenjini ngesivinini sokuhamba.
10. Ukuhiliza kuzwakala kufeni.

Injini Yokuhlola izosebenza futhi ikhodi izobhalelwa i-ECM lapho lokhu kungasebenzi kahle kwenzeka, okubangela ukuthi i-turbocharger ivale futhi inciphise amandla enjini ngesikhathi sokusheshisa.

Izizathu ezingenzeka

Izimbangela zekhodi yenkinga ye-P0239 zingabandakanya:

1. Vula isifunda senzwa yokucindezela kwe-turbocharger enenzuzo yangaphakathi.
2. Inzwa yokucindezela kwe-turbocharger eyonakele Isixhumi esibangela isekethe evulekile.
3. Ihhanisi lezintambo ezifushanisiwe phakathi kwenzwa ye-boost pressure kanye nemojula yokulawula injini (ECM).

Lezi zici zingabangela ukuthi ingcindezi ekhuphukayo ingaphathwa kahle, engahlotshaniswa nezinkinga ezimbalwa ezingaba khona, okuhlanganisa ukuvuza kwe-vacuum, izinkinga zesihlungi somoya, izinkinga ze-wastegate, izinkinga zokunikezwa kukawoyela we-turbo, ama-turbine blades awonakele, izinkinga zophawu lukawoyela, nokunye. Ngaphezu kwalokho, kungase kube nezinkinga ngokuxhunywa kukagesi nezinzwa.

Indlela yokuxilonga ikhodi yenkinga P0239?

Ukuhlonza izinkinga ze-turbo ngokuvamile kuqala ngezinketho ezivamile, futhi ukusebenzisa amathuluzi alula njengegeji yomshini wokuvala kanye negeji yokudayela kungase kusebenze kakhulu. Ngezansi ukulandelana kwezinyathelo zokuxilonga:

1. Qiniseka ukuthi injini isebenza ngokujwayelekile, awekho ama-spark plug amabi, futhi awekho amakhodi ahlobene nenzwa yokungqongqoza.
2. Ngokubanda kwenjini, hlola ukucinana kwezinsimbi endaweni yokuphuma ye-turbine, i-intercooler kanye ne-throttle body.
3. Zama ukunyakazisa i-turbine ku-outlet flange ukuze uqiniseke ukuthi inamathiselwe ngokuvikelekile.
4. Hlola ukuvuza okuningi kokuthathayo, okuhlanganisa namapayipi evacuum.
5. Khipha i-actuator lever ku-wastegate bese usebenzisa i-valve ngesandla ukuze ubone izinkinga ezingase zibe khona.
6. Faka i-vacuum gauge esikhaleni endaweni oyithathayo bese uhlola ivacuum ngenjini esebenzayo. Lapho kungenzi lutho, i-vacuum kufanele ibe phakathi kwamayintshi angu-16 no-22. Uma ingaphansi kuka-16, lokhu kungase kubonise isiguquli se-catalytic esinephutha.
7. Khulisa isivinini senjini sibe ngu-5000 rpm futhi ukhulule i-throttle ngenkathi ubheka umfutho okhulayo kugeji. Uma ingcindezi ingaphezu kwamakhilogremu angu-19, inkinga ingase ibe ngevalve yokudlula. Uma inzuzo ingashintshi phakathi kuka-14 no-19 lbs, imbangela ingase ibe inkinga nge-turbo ngokwayo.
8. Pholisa injini bese uhlola i-turbine, khipha ipayipi le-exhaust futhi uhlole isimo samablade eturbine angaphakathi ukuze ubone umonakalo, ama-blade agobile noma angekho, kanye nowoyela ku-turbine.
9. Hlola imigqa kawoyela ukusuka ebhulokhini lenjini ukuya endaweni ephakathi nendawo ye-turbine kanye nomugqa wokubuya ukuze uvuze.
10. Faka inkomba yokudayela ekhaleni le-turbine ephumayo futhi uhlole ukudlala kokuphela kwe-shaft ye-turbine. Uma umdlalo wokugcina ungaphezu kwamayintshi angu-0,003, kungase kubonise inkinga ngokuveza okumaphakathi.

Uma i-turbo isebenza ngokujwayelekile ngemva kokwenza lezi zivivinyo, isinyathelo esilandelayo singaba ukuhlola inzwa yokuthuthukisa kanye nezintambo usebenzisa i-volt/ohmmeter. Hlola amasignali phakathi kwenzwa kanye neyunithi yokulawula injini. Kubalulekile ukukhumbula ukuthi akuwona wonke amakhodi we-OBD2 atolikwa ngokufanayo ngabakhiqizi abahlukene, ngakho-ke kufanele ubheke imanuwali efanelekile ukuze uthole imininingwane eqondile.

Amaphutha okuxilonga

Ukuze uvimbele ukuxilonga, landela lezi ziqondiso ezilula:

1. Hlola ipayipi lenzwa ye-boost pressure ukuze uthole ukuvinjwa nama-kinks.
2. Qiniseka ukuthi uxhumo lukagesi lwenzwa luvikelekile nokuthi akukho ukuvuza noma ukugoba emapayipini okucindezela.

Ikuphi ukulungisa okuzolungisa ikhodi ye-P0239?

Uma i-boost sensor ingathumeli idatha yengcindezi efanele ku-ECM:

1. Shintshanisa inzwa yokuthuthukisa.
2. Hlola amapayipi enzwa ye-turbo kanye noxhumo ukuze uthole ama-kinks noma ama-blockages futhi uwalungise noma uwashintshe uma kunesidingo.
3. Lungisa izintambo zenzwa noma shintsha uxhumano ukuze ubuyisele ukusebenza okuvamile.

Ibucayi kangakanani ikhodi yenkathazo P0239?

Ukuthatha amandla okufushane kumjikelezo wezinzwa kungabangela ukushisa kwangaphakathi kwe-ECM, ikakhulukazi uma i-voltage yesifunda esifushane ingaphezu kuka-5 V.

Uma i-ECM ishisa kakhulu, kunengozi yokuthi imoto ngeke iqale futhi ingase ime.
