P0451 Evaporator Emission System Pressure Sensor Performance

I-P0451 - I-OBD-II Ikhodi Yenkinga Incazelo Yobuchwepheshe

I-Evaporative Emission Control Control Range/Ukusebenza

Isho ukuthini ikhodi yephutha P0451?

Ikhodi P0451 - "Inzwa yokucindezela ye-Evaporative Emission System"

Ikhodi P0451 iqalwa lapho imojuli yokulawula i-powertrain (PCM) yemoto ithola isignali kagesi enganembile noma engazinzile kusukela kunzwa yokucindezela yesistimu yokulawula ukuhwamuka.

I-evaporative emissions control system (EVAP) yakhelwe ukubamba futhi yelaphe umhwamuko kaphethiloli ukuze uvimbele ukuthi ungangeni emkhathini. Ikhodi P0451 ikhombisa izinkinga ngenzwa yokucindezela kulolu hlelo.

Izizathu ezingaba khona:

1. Inzwa yokucindezela ye-EVAP engalungile.
2. Intambo eyonakele noma isixhumi sikagesi esihlotshaniswa nenzwa yokucindezela.
3. Izinkinga ngohlelo lwe-EVAP, njengokuvuza noma ukuvinjwa.
4. Ukusebenza kwe-PCM okungalungile noma ezinye izinkinga zikagesi.

Kunconywa ukuthi uxhumane nomakhenikha oqeqeshiwe noma isikhungo sesevisi ukuze unqume ngokunembile futhi ulungise imbangela.

Izizathu ezingenzeka

Ikhodi ye-P0451 ingasethwa ngenxa yezizathu ezilandelayo:

• Inzwa yokucindezela ye-EVAP engalungile.
• Ikepisi yamafutha exegayo noma engekho.
• I-valve yokukhulula ingcindezi ethangini likaphethiloli ivalekile.
• Amapayipi/imigqa ye-EVAP eyonakele, ecekelwe phansi noma eshisiwe.
• Isitsha samalahle esiqhekekile noma esiphukile.

Okuvame kakhulu kulezi zimbangela ithangi likaphethiloli elingalungile, iyunithi yokudlulisa ithangi likaphethiloli engalungile, inzwa yokucindezela evulekile noma emfishane noma isekethe kunzwa yokucindezela ithangi likaphethiloli.

Yiziphi izimpawu zekhodi yephutha? P0451?

Izimpawu zekhodi ye-P0451 zingase zibe zincane futhi zihlanganisa okulandelayo:

• Izimo eziningi ezinekhodi P0451 azibonisi izimpawu.
• Kungase kube khona ukwehla kancane ukonga kukaphethiloli.
• I-Malfunction Indicator Light (MIL) ephaneli yezinsimbi iyavuleka.

Uma imoto yakho ikhiqize ikhodi engu-P0451, cishe ngeke kudingeke ubhekane nanoma yiziphi izimpawu ezibucayi. Ezimweni eziningi, okuwukuphela kophawu olubonakalayo kuzoba ukukhanya kwenjini yokuhlola kudeshibhodi yakho ezayo. Kodwa-ke, ngaphezu kwalesi sibonakaliso, ungase futhi ubone iphunga elibi likaphethiloli eliphuma enjini, elibangelwa ukukhululwa kwe-fuel vapors.

Indlela yokuxilonga ikhodi yephutha P0451?

Ukuxilonga kahle ikhodi ye-P0451 kungaba nzima. Iningi labanikazi bezimoto bakhetha ukuphathisa lo msebenzi kochwepheshe futhi balethe izimoto zabo ukuze zihlolwe.

Inqubo yokuxilonga ivamise ukuqala ngokuthi uchwepheshe afunde amakhodi agcinwe ku-PCM yemoto esebenzisa isithwebuli se-OBD-II. Lawa makhodi abe esehlaziywa futhi uchwepheshe uqala ukubuyekeza ngalinye ngendlela agcinwe ngayo ku-PCM. Ngokuvamile, ngemva kwekhodi ye-P0451, amanye amakhodi e-OBD-II ahlobene nawo angase acushwe futhi agcinwe.

Ngemva kokuqedwa kokuskena, uchwepheshe wenza ukuhlola okubonakalayo kwemoto nazo zonke izinzwa namamojula ahlobene.

Ukuskena nokuxilonga ikhodi ye-P0451 kuyinqubo eyinkimbinkimbi futhi kunconywa ukuthi iyekelwe kuchwepheshe. Esikhundleni sokuzama ukuzixilonga, kungcono ukuya kochwepheshe abanolwazi.

Ngemva kokuskena nokukhomba ikhodi, uchwepheshe uzoqala ngokuhlola okubukwayo, lapho ezohlola khona izintambo, izixhumi, namasekethe ngomonakalo. Uma amaphutha akhonjiwe esexazululiwe, ikhodi ye-P0451 izosulwa futhi uhlelo luzohlolwa kabusha.

Uma uchwepheshe ecabanga ukuthi konke kuhamba ngohlelo, uzoqhubeka nokuhlola isitsha samalahle, i-valve yokuhlanza, i-vacuum ne-steam hoses, nazo zonke ezinye izakhi ezihlobene nohlelo lokulawula ukuhwamuka. Ingxenye ngayinye izobhekwa futhi, uma kunesidingo, ilungiswe. Amakhodi azosulwa futhi injini ihlolwe kabusha kuze kube yilapho inkinga yekhodi isixazululiwe.

Sicela uqaphele ukuthi uhlu olunemininingwane eyengeziwe lwezikhungo zesevisi eziseduze nawe lungatholakala ohlwini lwe-KBB Service Centre.

Lapho uxilonga ikhodi P0451, amathuluzi alandelayo nezinyathelo zingadingeka:

• Isithwebuli sokuxilonga.
• Digital volt/ohmmeter.
• Umthombo othembekile wolwazi mayelana nemoto yakho, njenge-All Data DIY.
• Umshini wokubhema (okungenzeka).
• Hlola ngokubonakalayo amapayipi nemigqa yesistimu ye-EVAP, kanye namahhanisi nezixhumi zikagesi.
• Rekhoda ulwazi lwekhodi futhi umise idatha yozimele.
• Ihlola ingcindezi yesistimu ye-EVAP kusetshenziswa ukugeleza kokuxilonga (isikena).
• Ihlola inzwa yokucindezela kwe-EVAP.
• Ukuhlola amasekhethi kagesi kusetshenziswa i-DVOM.
• Shintsha amasekhethi aphukile noma amafushane njengoba kudingeka.

Khumbula ukuthi ingcindezi ephansi noma ephezulu ye-EVAP ingabangela ukuthi i-P0451 ivele, futhi ingabangelwa izinkinga zikagesi noma zemishini.

Amaphutha okuxilonga

Ukuziba amanye amakhodi amaphutha

Iphutha elilodwa elijwayelekile lapho uxilonga ikhodi ye-P0451 ukunganaki amanye amakhodi ezinkinga. Uma kunezinkinga ngohlelo lwe-evaporative emission control (EVAP), amanye amakhodi enkathazo ahlobene nawo angase acushwe, njenge-P0440, P0442, P0452, njalo njalo. Ukuziba lawa makhodi engeziwe kungase kuphumele ekulahlekeni kwezinkomba ezibalulekile futhi kube nzima inqubo yokuxilonga.

Ukuhlola okungabonwayo kwesistimu ye-EVAP

Elinye iphutha ukungahloli isistimu ye-EVAP ngokubukeka ngokwanele. Kwesinye isikhathi inkinga ingadalwa amapayipi alimele, izixhumi, noma ukuvuza ohlelweni. Ukungaziniki isikhathi sokuhlolisisa lezi zingxenye kungenza kube nzima ukubona umsuka wenkinga.

Ungenzi ukuxilonga okuphelele

Iphutha futhi lilele eqinisweni lokuthi ukuxilonga kukhawulelwe kumakhodi wephutha okufunda kuphela nokufaka esikhundleni senzwa yokucindezela kwe-EVAP. Le khodi ingabangelwa izizathu ezihlukahlukene, futhi ukushintshwa okungalawulwa kwenzwa ngaphandle kokuxilongwa okujulile kungase kube isilinganiso esingasebenzi futhi esibizayo.

Ibucayi kangakanani ikhodi yephutha? P0451?

Ikhodi P0451 ingenye yamakhodi e-OBD-II abucayi kakhulu. Ngokuvamile okuwukuphela kophawu oluphawulekayo ukukhanya kwenjini yokuhlola okuvela kudeshibhodi yemoto yakho. Nokho, nakuba zingekho izimpawu ezisobala, imoto yakho ingase ikhiphe intuthu kaphethiloli eyingozi nengemnandi kanye nephunga. Ngakho-ke, kubalulekile ukuthi ube nochwepheshe oqeqeshiwe ohlola imoto yakho futhi alungise inkinga ngokwentshisekelo yezempilo nokuphepha.

Yikuphi ukulungisa okuzosiza ukuqeda ikhodi? P0451?

Ukulungiswa okulandelayo kuyadingeka ukuze kuxazululwe ikhodi P0451:

1. Shintsha noma lungisa inzwa yokucindezela kwe-EVAP uma inephutha.
2. Hlola bese ubuyisela ikepisi yethangi likaphethiloli uma ilahlekile noma ilimele.
3. Hlanza noma shintsha i-valve yokukhulula ithangi likaphethiloli uma ivalekile noma inephutha.
4. Hlola futhi ubuyisele wonke amapayipi nemigqa ye-EVAP eyonakele, ecekeleke phansi, noma eshile.
5. Ukushintsha ithini le-carbon filter ephukile noma eliphukile uma lonakele.

Kunconywa ukuthi ukuxilongwa nokulungiswa kwenziwe ngochwepheshe abaqeqeshiwe njengoba ukuxilonga i-P0451 kungase kudinge okokusebenza okukhethekile nolwazi.

P0451 - Ulwazi oluthize lomkhiqizo

Ikhodi yenkinga i-P0451 yikhodi ehlobene nenzwa yokucindezela kwesistimu yokukhipha umusi. Le khodi ingasetshenziswa ezinhlobonhlobo zezimoto ezifakwe uhlelo lwe-OBD-II. Nazi izincazelo ze-P0451 zeminye imikhiqizo ethile:

1. I-Chevrolet/GMC: I-P0451 isho ukuthi “Inzwa Yokucindezela Yesistimu Yokuphuma Evaporative/Ukushintsha”. Lena ikhodi ehlotshaniswa nesistimu yokulawula ukungcola okuhwamukayo.
2. Ford: I-P0451 ihunyushwa ngokuthi “Inzwa Yokucindezela Kwethangi Yamafutha”. Le khodi ibonisa izinkinga zokucindezela ohlelweni lwethangi likaphethiloli.
3. Toyota: I-P0451 isho ukuthi "Iphutha Lenzwa Yokucindezela Kwesistimu ye-EVAP." Le khodi ihlobene nesistimu ye-EVAP kanye nokucindezela kwayo.
4. IVolkswagen/Audi: I-P0451 ingachazwa ngokuthi “Inzwa Yokucindezela Kwesistimu ye-EVAP”. Lokhu kungenxa yesistimu yokulawula ukukhishwa kwe-evaporative.
5. Dodge/Ram: I-P0451 isho ukuthi "Iphutha Lenzwa Yokucindezela Kwesistimu ye-EVAP." Le khodi ihlobene nesistimu ye-EVAP.

Sicela uqaphele ukuthi incazelo eqondile yekhodi ingase ihluke kancane kuye ngokuthi yenziwe kanjani nemodeli yemoto ethile, ngakho-ke kunconywa ukuthi uhlole incwadi yesevisi nokulungisa imoto yakho ethile noma uthintane nomakhenikha oqeqeshiwe ukuze uthole ukuxilonga nokukhanda okunembe kakhudlwana. .
