I-P0251 i-Fuel metering control ukungasebenzi kahle kwepompo yephethiloli ephezulu

Ikhodi Yenkinga ye-OBD-II - P0251 - Ishidi Ledatha

Ukungasebenzi kahle kolawulo lokulinganisa uphethiloli kwepompo kaphethiloli ephezulu (cam / Rotor / injector)

Isho ukuthini ikhodi yenkinga P0251?

Le Generic Transmission / Engine DTC imvamisa ingasebenza kuzo zonke izinjini zikadizili ezine-OBD-II (ezinjengeFord, Chevy, GMC, Ram, njll.), Kepha zivame kakhulu kwezinye izimoto zakwaMercedes Benz neVW.

Yize kuvamile, izinyathelo eziqondile zokulungisa zingahluka ngokuya ngemodeli yonyaka, ukwakheka, imodeli, nokucushwa kokudluliswa.

Iphampu yomjovo "A" wesifunda wokulawula amamitha uvame ukutholakala ngaphakathi noma eceleni kwepompo yomjovo, eboshelwe enjinini. Isifunda "A" sokulawula ipayipi kaphethiloli ngokuvamile siqukethe inzwa yesitimela sikaphethiloli (i-FRP) kanye ne-actuator yobuningi bephethiloli.

Inzwa ye-FRP iguqula inani likaphethiloli we-diesel ohlinzekwa yi-actuator yobuningi be-fuel ezijovweni zibe isignali kagesi eya kwi-powertrain control module (PCM).

I-PCM ithola lesi siginali sevolthi ukuthola ukuthi izofaka uphethiloli ongakanani enjinini ngokuya ngezimo zokusebenza kwenjini. Le khodi isethwe uma lokhu okufakwayo kungahambisani nezimo ezijwayelekile zokusebenza kwe-injini ezigcinwe kwimemori ye-PCM, noma umzuzwana, njengoba kukhonjisiwe yile DTC. Iphinde ibheke isignali yamandla kagesi kusuka enzwa ye-FRP ukuthola ukuthi ilungile yini lapho kuqala ukhiye uvuliwe.

I-Code P0251 High Pressure Fuel Injection Pump Fuel Metering Control Ukungasebenzi (i-cam / rotor / injector) kungasethwa ngenxa yezinkinga zemishini (imvamisa izinkinga ze-EVAP system mechanical) noma izinkinga zikagesi (FRP sensor circuit). Akufanele zinganakwa ngesikhathi sesigaba sokuxazulula inkinga, ikakhulukazi lapho kubhekwane nenkinga efika ngezikhathi ezithile. Thinta incwadi yakho yokulungisa izimoto ukuthola ukuthi iyiphi ingxenye yochungechunge engu- "A" yohlelo lwakho lokusebenza.

Izinyathelo zokuxazulula inkinga zingahluka ngokuya ngomenzi, uhlobo lwenzwa ye-FRP nemibala yocingo.

Buyini ubunzima bale DTC?

Ubukhulu kuleli cala buzoba buphansi. Njengoba lokhu kuyiphutha likagesi, i-PCM ingayinxephezela ngokwanele.

Yiziphi ezinye izimpawu zekhodi P0251?

Izimpawu zekhodi yenkinga ye-P0251 zingafaka:

• Ilambu Lenkomba Engasebenzi (MIL) Ukukhanyisa
• Ukwehla komnotho kaphethiloli
• Ukuqala okunensayo noma ukungaqali
• Intuthu ivela epayipini le-exhaust
• Izitebele zezinjini
• Ama-misfire okungenani

Yiziphi ezinye zezimbangela ezivamile zekhodi?

Izizathu zale khodi ye-P0251 zingafaka:

• Ukuvuleka kumjikelezo wesiginali kunzwa ye-FRP - kungenzeka
• Okufushane kuya ku-voltage kumjikelezo wesiginali yenzwa ye-FRP - kungenzeka
• Kufushane ukuya phansi kumjikelezo wesiginali kuya kunzwa ye-FRP - Kungenzeka
• Amandla noma ikhefu lomhlaba ku-FRP sensor - kungenzeka
• Inzwa ye-FRP enephutha - mhlawumbe
• I-PCM Yehlulekile - Akwenzeki
• Uphethiloli ongcolile, ongalungile noma omubi
• Inzwa yokubona engcolile
• Iphampu yamafutha evalekile, isihlungi sikaphethiloli noma isijojo sikaphethiloli.
• Ukungasebenzi kahle kwenzwa yokushisa komoya oyithathayo, inzwa yokuma kwe-crankshaft noma inzwa ye-accelerator pedal position
• I-activator yokulawula uphethiloli engalungile
• Imojuli yokulawula injini enephutha
• ukuvuza komjovo kaphethiloli
• Kufushane ukuya phansi noma amandla kumahhanisi ahlotshaniswa nenzwa yokushisa komoya oyithathayo, inzwa yokuma kwe-crankshaft, noma inzwa yokuma kwe-accelerator.
• Ukubola kwenzwa yokushisa komoya oyithathayo, inzwa yokuma kwe-crankshaft, inzwa ye-accelerator pedal position, izixhumi zokujova uphethiloli noma amahhanisi ezintambo ahlobene

Yiziphi ezinye zezinyathelo zokuxazulula inkinga nge-P0251?

Iphuzu elihle lokuqala ngaso sonke isikhathi ukubheka i-Technical Service Bulletins (TSB) yemoto yakho. Inkinga yakho ingaba inkinga eyaziwayo ngokulungiswa okwenziwe ngumkhiqizi futhi kungakongela isikhathi nemali ngesikhathi sokuxilongwa.

Bese uthola inzwa ye-FRP emotweni yakho. Le nzwa ivame ukutholakala ngaphakathi / ohlangothini lwempompo kaphethiloli eboshelwe enjinini. Uma usutholakele, bheka ngokubonakalayo isixhumi nentambo. Bheka imihuzuko, izikhafu, izintambo eziveziwe, amamaki okushisa, noma ipulasitiki ebunjiwe. Nqamula isixhumi futhi uhlole ngokucophelela amatheminali (izingxenye zensimbi) ngaphakathi kwesixhumi. Bona ukuthi zibukeka zishisiwe noma zinombala oluhlaza okhombisa ukugqwala. Uma udinga ukuhlanza ama-terminals, sebenzisa i-electric contact cleaner kanye ne-plastic bristle brush. Vumela ukomisa nokufaka igrisi kagesi lapho amatheminali ethinta khona.

Uma unethuluzi lokuskena, sula ama-DTCs kwimemori bese ubona ukuthi iyabuya yini i-P0251. Uma lokhu kungenjalo, kungenzeka ukuthi kunenkinga yokuxhuma.

Uma ikhodi ye-P0251 ibuya, kuzodingeka sihlole inzwa ye-FRP namasekethe ahambisanayo. Ngokucisha ukhiye, nqamula isixhumi senzwa ye-FRP. Xhuma ukuhola okumnyama kusuka ku-DVM kuye ekugcineni kwensimbi kusixhumi se-harp senzwa ye-FRP. Xhuma ukuhola okubomvu kusuka ku-DVM kuye esigungwini samandla kusixhumi se-harness senzwa ye-FRP. Vula ukhiye, injini icishiwe. Bheka imininingwane yomkhiqizi; i-voltmeter kufanele ifunde ama-volts ayi-12 noma ama-volts ama-5. Uma kungenjalo, lungisa ugesi noma ucingo lwaphansi noma ubeke i-PCM esikhundleni.

Uma ukuhlolwa kwangaphambilini kudlula, kuzodingeka sihlole ucingo lwesiginali. Ngaphandle kokukhipha isixhumi, hambisa intambo ebomvu ye-voltmeter kusuka esigungwini sezintambo zamandla kuya esigungwini sentambo yesiginali. I-voltmeter manje kufanele ifunde ama-volts ama-5. Uma kungenjalo, lungisa ucingo lwesiginali noma ungene esikhundleni se-PCM.

Uma zonke izivivinyo zangaphambilini zidlula futhi uqhubeka nokuthola i-P0251, kungenzeka ukuthi ikhombise i-FRP inzwa / i-actuator yobuningi ehlulekile, yize i-PCM ehlulekile ingakhishwa ngaphandle kuze kube yilapho inzwa ye-FRP / i-fuel quantity actuator ishintshwa. Uma ungaqiniseki, funa usizo kudokotela oqeqeshiwe wezimoto. Ukufaka kahle, i-PCM kufanele ihlelwe noma ilinganiselwe imoto.

IYENZA KANJANI IKHODI YE-MCHHANIC DIAGNOSTIC P0251?

• Ibonisa idatha yozimele ye-DTC ukuze inqume amanani enzwa yokubona, inzwa yendawo ye-crankshaft, inzwa ye-accelerator pedal position, kanye nenzwa yokushisa komoya oyithathayo.
• Isebenzisa ithuluzi lokuskena ukuze ibuke impendulo yesikhathi sangempela kusukela kunzwa yokubona, inzwa yokuma kwe-crankshaft, inzwa ye-accelerator pedal position, nenzwa yezinga lokushisa lomoya.
• Usebenzisa i-multimeter, hlola ukufundwa kwamandla kagesi namazinga okumelana* wenzwa yokubona, inzwa yokuma kwe-crankshaft, inzwa yokuma kwe-accelerator, kanye nenzwa yokushisa komoya oyithathayo.
• Hlola izinga likaphethiloli
• Yenza ukuhlolwa komfutho kaphethiloli

* Amandla kagesi kanye nokumelana nengxenye ngayinye kufanele kuhambisane nemibandela yomkhiqizi. Imininingwane izohluka kuye ngonyaka wokukhiqiza kanye nemodeli yemoto. Imininingwane yemoto yakho ethile ingatholakala kuwebhusayithi efana ne-ProDemand noma ngokubuza umakhenikha.

AMAPHUTHA AVAMILE LAPHO KUHLOLWA IKHODI P0251

Kunezinto eziningi ezingabangela ikhodi yenkathazo ye-P0251. Kubalulekile ukuhlola ngokucophelela izingxenye ezifakwe ohlwini njengembangela engaba khona yenkinga ngaphambi kokubika ukuthi inesici. Okokuqala, thola ukuthi yiziphi izingxenye ezisebenzayo emotweni yakho. Bese uhlola inzwa yokubona, inzwa yokuma kwe-crankshaft, inzwa ye-accelerator pedal position kanye nenzwa yokushisa komoya oyithathayo, uma kusebenza.

YIKUPHI UKULUNGISA ONGALUNGISA IKHODI P0251?

• Ukushintsha inzwa yokuma ye-crankshaft enephutha
• Ukushintsha inzwa yokuma kwe-throttle enephutha
• Ukushintsha inzwa yokushisa komoya yokungenisa engalungile
• Ukushintsha inzwa yokubona enesici
• Ukuhlanza inzwa ye-optical engcolile

• Ukulungisa isekethe evulekile, emfushane noma ephezulu kusekethi yenzwa yokushisa komoya wokungena
• Ukulungisa okufushane, okuvulekile, noma okuphansi kusekethe yenzwa ye-throttle position.
• Ukulungisa indawo evulekile, emfushane noma ephansi kusekethe yenzwa yendawo ye-crankshaft
• Ukushintsha imojuli yokulawula injini ehlulekile
• Ukuxazulula inkinga emfushane, evuleleke phansi, noma phansi kuzintambo ezihlotshaniswa nenzwa yokubona

IMIBONO ENGEZIWE UKUZE UQAPHELE IKHODI P0251

Qaphela ukuthi ngemva kokushintsha inzwa yokubona ehlulekile, ithuluzi lokuskena kufanele lisetshenziswe ukuze kutholwe kabusha ama-setpoints ekhamera.
