P0251 Mafuta oyendetsa metering amawonongeka pompopompo wamafuta

Khodi Yovuta ya OBD-II - P0251 - Kufotokozera Zaukadaulo

Kulephera kwa kayendedwe kazitsulo ka mafuta pamphamvu yamagetsi (cam / rotor / injector)

Kodi vuto la P0251 limatanthauza chiyani?

Generic Transmission / Engine DTC imatha kugwiritsidwa ntchito pamakina onse a OBD-II okhala ndi dizilo (monga Ford, Chevy, GMC, Ram, ndi zina zambiri), koma amapezeka kwambiri mgalimoto zina za Mercedes Benz ndi VW.

Ngakhale ndizazonse, njira zowongolera zenizeni zimatha kusiyanasiyana kutengera mtundu wachitsanzo, kapangidwe, kapangidwe kake, ndi kasinthidwe kakutumizirana.

Pampu ya jekeseni "A" yoyang'anira metering nthawi zambiri imakhala mkati kapena mbali ya pampu ya jekeseni, yomwe imamangiriridwa ku injini. Dera loyendetsa metering "A" limakhala ndi kachipangizo ka njanji yamafuta (FRP) komanso chopangira mafuta.

Chojambulira cha FRP chimatembenuza kuchuluka kwa mafuta a dizilo omwe amaperekedwa ndi mafuta ochulukitsa kwa ma jakisoni kukhala mbendera yamagetsi yamagetsi yamagetsi yamagetsi (PCM).

PCM imalandira chizindikiro chamagetsi ichi kuti mudziwe kuchuluka kwa mafuta omwe angaike mu injini kutengera momwe makina akugwirira ntchito. Khodi iyi ikhazikitsidwa ngati cholowetsachi sichikugwirizana ndi magwiridwe antchito ainjini osungidwa mu kukumbukira kwa PCM, ngakhale kwa mphindi, monga DTC iyi ikuwonetsera. Imawunikiranso mayendedwe amagetsi kuchokera ku sensa ya FRP kuti muwone ngati ndi yolondola pomwe kiyi idayatsidwa.

Code P0251 High Pressure Fuel Injection Pump Fuel Metering Control Kulephera kugwira ntchito (cam / rotor / injector) kumatha kukhazikitsidwa chifukwa chamakina (nthawi zambiri mavuto amakono a EVAP) kapena mavuto amagetsi (FRP sensor dera). Sayenera kunyalanyazidwa panthawi yamavuto, makamaka pakakhala vuto lakanthawi. Onaninso buku lanulo lokonza magalimoto kuti mudziwe gawo lina la unyolo womwe uli "A" kuti mugwiritse ntchito.

Njira zothetsera mavuto zimatha kusiyanasiyana kutengera wopanga, mtundu wa sensa ya FRP ndi mitundu ya waya.

Kodi kuuma kwa DTC kumeneku ndi kotani?

Kukula kwake pankhaniyi kudzakhala kotsika. Popeza uku ndi vuto lamagetsi, PCM imatha kulipirira mokwanira.

Kodi zizindikiro za P0251 ndi ziti?

Zizindikiro za vuto la P0251 zitha kuphatikiza:

• Nyali Yazizindikiro Zosagwira (MIL) Kuunikira
• Kuchepetsa mafuta
• Kuyamba pang'onopang'ono kapena osayamba
• Utsi umachokera ku chitoliro chotulutsa mpweya
• Zida za injini
• Zowonongeka pang'ono

Kodi zina mwazomwe zimayambitsa codezi ndi ziti?

Zifukwa za code iyi P0251 zitha kuphatikizira izi:

• Kutseguka mumayendedwe azizindikiro kupita ku sensa ya FRP - kotheka
• Short to voltage mu mawonekedwe amtundu wa FRP sensor - zotheka
• Wachidule mpaka pansi pozungulira chizindikiro kupita ku FRP sensor - Zotheka
• Mphamvu kapena kutsika pansi pa FRP sensor - zotheka
• Sensa yolakwika ya FRP - mwina
• PCM yolephera - Zokayikitsa
• Mafuta owonongeka, olakwika kapena oyipa
• Dirty Optical sensor
• Pampu yamafuta yotsekeka, fyuluta yamafuta kapena jekeseni wamafuta.
• Kusagwira ntchito kwa sensor kutentha kwa mpweya, crankshaft position sensor kapena accelerator pedal position sensor
• Makina owongolera mafuta olakwika
• Module yowongolera injini yolakwika
• kutayikira kwa jekeseni wamafuta
• Chachifupi mpaka pansi kapena mphamvu mu harni yolumikizidwa ndi sensa ya kutentha kwa mpweya, crankshaft position sensor, kapena accelerator pedal position sensor.
• Kuwonongeka pa sensa ya kutentha kwa mpweya, crankshaft position sensor, accelerator pedal position sensor, zolumikizira mafuta ojambulira kapena ma waya ogwirizana nawo.

Kodi ndi njira ziti zina zothetsera P0251?

Poyambira bwino nthawi zonse mumayang'ana Technical Service Bulletins (TSB) pagalimoto yanu. Vuto lanu litha kukhala vuto lodziwika bwino lokonzedwa ndi opanga ndipo limatha kukupulumutsirani nthawi ndi ndalama pakuwunika.

Kenako pezani sensa ya FRP pagalimoto yanu. Chojambulira ichi nthawi zambiri chimakhala mkati / pambali pa pampu yamafuta yolumikizidwa ku injini. Mukapezeka, yang'anani zowunikira cholumikizira ndi zingwe. Fufuzani zokopa, scuffs, mawaya owonekera, mabala owotchera, kapena pulasitiki wosungunuka. Chotsani cholumikizira ndikuyang'anitsitsa malo (zitsulo) mkati mwa cholumikizacho. Onani ngati akuwoneka owotcha kapena ali ndi utoto wobiriwira wosonyeza dzimbiri. Ngati mukufuna kuyeretsa malo, gwiritsani ntchito zotsukira zamagetsi ndi burashi ya pulasitiki. Lolani kuti muumitse ndikupaka mafuta amagetsi pomwe ma terminals amakhudza.

Ngati muli ndi chida chosakira, chotsani ma DTC pamtima ndikuwona ngati P0251 ibwerera. Ngati sizili choncho, ndiye kuti vuto ndilokulumikizana.

Ngati nambala ya P0251 ibwerera, tifunika kuyesa sensa ya FRP ndi ma circuits ena. Mukatsegula fungulo, tulutsani cholumikizira chamagetsi cha FRP. Lumikizani mtovu wakuda kuchokera ku DVM kupita kumalo osungira nthaka pazitsulo zolumikizira za FRP sensor. Lumikizani kutsogolera kofiira kwa DVM kumalo opangira magetsi pazitsulo zolumikizira za FRP sensor. Tsegulani kiyi, injini izima. Chongani specifications wopanga; voltmeter iyenera kuwerengera ma volts 12 kapena 5 volts. Ngati sichoncho, konzani magetsi kapena waya wapansi kapena m'malo mwa PCM.

Ngati mayeso am'mbuyomu adutsa, tifunika kuyang'ana waya wamagetsi. Popanda kuchotsa cholumikizira, sungani waya wofiira wa voltmeter kuchokera pamagetsi amagetsi kupita kumalo opangira ma waya. Voltmeter iyenera tsopano kuwerenga ma volts 5. Ngati sichoncho, konzani waya wamagetsi kapena m'malo mwa PCM.

Ngati mayesero onse am'mbuyomu adadutsa ndikupitiliza kulandira P0251, zikuwonetsa kuti cholephera cha FRP / mafuta ochulukirapo olephera, ngakhale PCM yolephera siyingachotsedwe mpaka pomwe kachipangizo ka FRP / mafuta ochulukirapo asinthidwa. Ngati simukudziwa, pemphani thandizo kwa katswiri wodziwa zamagalimoto. Kuti muyike bwino, PCM iyenera kukonzedwa kapena kusinthidwa pagalimoto.

KODI MACHHANIC DIAGNOSTIC KODI P0251 Imatani?

• Imawonetsa DTC amaundana deta kuti adziwe kufunikira kwa sensor ya kuwala, crankshaft position sensor, accelerator pedal position sensor, ndi sensor kutentha kwa mpweya.
• Imagwiritsa ntchito chida chojambulira kuti muwone mayankho anthawi yeniyeni kuchokera ku sensa ya kuwala, crankshaft position sensor, accelerator pedal position sensor, ndi sensa ya kutentha kwa mpweya.
• Pogwiritsa ntchito ma multimeter, yang'anani kuchuluka kwa ma voliyumu ndi kuchuluka kwa mphamvu * ya Optical sensor, crankshaft position sensor, accelerator pedal position sensor, ndi sensa ya kutentha kwa mpweya.
• Onani mtundu wamafuta
• Amayesa kuthamanga kwamafuta

* Mphamvu yamagetsi ndi kukana kwa gawo lililonse liyenera kutsata zomwe wopanga amapanga. Zofotokozera zidzasiyana malinga ndi chaka chopangidwa ndi mtundu wagalimoto. Zambiri zamagalimoto anu zitha kupezeka patsamba monga ProDemand kapena pofunsa makaniko.

ZOPHUNZITSA ZAMBIRI PAMENE AMADZIWA KODI P0251

Pali zinthu zambiri zomwe zingayambitse vuto la P0251. Ndikofunikira kuyesa mozama zigawo zomwe zalembedwa ngati zomwe zingayambitse vuto musananene kuti zili ndi vuto. Choyamba, fufuzani kuti ndi zigawo ziti zomwe zimagwira ntchito pagalimoto yanu. Kenako yang'anani sensor ya kuwala, crankshaft position sensor, accelerator pedal position sensor ndi kutentha kwa mpweya, ngati kuli koyenera.

KODI KUKONZA KODI KUUNGAKONZE KODI P0251)?

• Kusintha kachipangizo kolakwika ka crankshaft
• Kulowetsa sensor yolakwika ya throttle position
• Kulowetsa sensor yolakwika ya kutentha kwa mpweya
• Kusintha kachipangizo kamene kamasokonekera

• Kuthana ndi vuto lalifupi, lotseguka pansi, kapena pansi pa waya wolumikizidwa ndi sensor ya kuwala

ZOWONJEZERA ZOWONJEZERA KUDZIWA KODI P0251

Zindikirani kuti mutatha kusintha sensor yolephera, chida chojambulira chiyenera kugwiritsidwa ntchito kuti mupezenso malo opangira cam.

P0251 ✅ ZIZINDIKIRO NDI KUTHETSA ZOYENERA ✅ - Khodi yolakwika OBD2

Mukufuna thandizo lina ndi code P0251?

Ngati mukufunabe thandizo ndi DTC P0251, lembani funso mu ndemanga pansipa pamutuwu.

ZINDIKIRANI. Izi zimaperekedwa kuti zidziwitse zokha. Sikuti tizigwiritsa ntchito ngati malingaliro okonzanso ndipo sitili ndi udindo pazomwe mungachite pagalimoto iliyonse. Zomwe zili patsamba lino ndizotetezedwa ndi zovomerezeka.
