P0251 Fuel metering kudzora kusashanda kweiyo yakakwira yekumanikidza peturu pombi

OBD-II Dambudziko Code - P0251 - Datasheet

Kusashanda kwemafuta emagetsi ekudzora epombi yekumanikidza peturu (cam / rotor / injector)

Ko dambudziko rekodhi P0251 rinorevei?

Iyi Generic Transmission / Injini DTC inowanzo shanda kune ese OBD-II enjini dzedhiziri (dzakadai seFord, Chevy, GMC, Ram, nezvimwewo), asi yakajairika mune dzimwe mota dzeMercedes Benz neVW.

Kunyangwe yakajairika, matanho chaiwo ekugadzirisa anogona kusiyanisa zvichienderana negore remodheru, gadzira, modhi, uye gadziriso yekufambisa.

Iyo jekiseni pombi "A" metering yekudzivirira wedunhu inowanzo kuve iri mukati kana kudivi repombi jekiseni, iro rakanamirwa kune injini. Iyo "A" peturu pombi yemamita ekudzora wedunhu kazhinji ine chinzvimbo chemafuta peturu nzvimbo (FRP) sensor uye huwandu hwemafuta actuator.

Inzwa yeFRP inoshandura huwandu hwedhiziri hunowanikwa nemafuta ekuwedzera actuator kune majekiseni kuita chiratidzo chemagetsi kune powertrain control module (PCM).

Iyo PCM inogashira iyi voltage chiratidzo kuti ione kuti yakawanda sei mafuta iyo yaizoisa muinjini zvichibva painjini yekushandisa mamiriro. Iyi kodhi inoiswa kana iko kuiswa kusingaenderane neyakajairika injini yekushandisa mamiriro akachengetwa muPCM memory, kunyangwe kwechipiri, sekuratidzira kweiyi DTC. Inotarisawo chiratidzo chemagetsi kubva kuFRP sensor kuona kana chiri chechokwadi kana kiyi yatanga kuvhurwa.

Code P0251 Yakakwira Pressure Fuel Pump Fuel Metering Kudzora Kusashanda (cam / rotor / injector) kunogona kumisikidzwa nekuda kweanogadzira (kazhinji EVAP sisitimu yemagetsi matambudziko) kana emagetsi (FRP sensor redunhu) matambudziko. Ivo havafanirwe kufuratirwa panguva yechinetso chekutambudza, kunyanya kana uchiita nedambudziko repakati. Tarisa bhuku rako chairo rekugadzirisa mota kuti uone chikamu checheni ichi "A" kune chako chaicho chikumbiro.

Matanho ekugadzirisa matambudziko anogona kusiyana zvichienderana nemugadziri, FRP sensor mhando, uye waya mawara.

Chii chakakomba cheiyi DTC?

Kuomarara mune ino kesi kunenge kuri kushoma. Sezvo uku kukundikana kwemagetsi, iyo PCM inogona kuripa zvakakwana.

Ndezvipi zvimwe zviratidzo zvekodhi P0251?

Zviratidzo zveP0251 kodhi kodhi inogona kusanganisira:

• Kukanganisa Chiratidzo Lamp (MIL) Kujekesa

• Ipfupi kusvika pasi kana simba mune harness yakabatana neinopinza yemhepo tembiricha sensor, crankshaft chinzvimbo sensor, kana accelerator pedal position sensor.
• Corrosion pane inopinza tembiricha yemhepo sensor, crankshaft position sensor, accelerator pedal position sensor, fuel injector connectors kana mawiring harnesses.

Ndeapi mamwe matanho ekutambudza iyo P0251?

Nzvimbo yakanaka yekutanga nguva dzose yekutarisa technical Service Bulletins (TSB) yemotokari yako. Dambudziko rako rinogona kunge riri nyaya inozivikanwa ine inozivikanwa inogadzira-yakaburitswa gadziriso uye inogona kukuisira nguva nemari panguva yekuongorora.

Wobva watsvaga iyo FRP sensor pamotokari yako. Iyi sensor inowanzo kuve iri mukati / padivi pepombi yemafuta yakasungirirwa kune injini. Paunenge wawanikwa, zviongorore ongorora chinobatanidza uye wiring. Tarisa mitsetse, scuffs, waya dzakafumurwa, kupisa maki, kana plastiki yakanyungudika. Dzinga chinongedzo uye nyatsoongorora zviteshi (simbi zvikamu) mukati mechibatanidzi. Tarisa uone kana vachitaridzika kunge akatsva kana vane tint yegirini inoratidza kuora. Kana iwe uchida kuchenesa zviteshi, shandisa yemagetsi yekubata yakachenesa uye purasitiki bristle bhurasho. Rega kuomesa nekuzora mafuta emagetsi panobatwa zviteshi.

Kana iwe uine turusi rekushandisa, bvisa maDTCs kubva mundangariro uye uone kana P0251 ichidzoka. Kana iyi isiri iyo kesi, saka panogona kunge paine chinetso chekubatanidza.

Kana iyo P0251 kodhi ikadzoka, isu tichafanirwa kuyedza iyo FRP sensor uye maseketi akabatana. Nekiyi OFF, patsanura iyo FRP sensor yemagetsi yekubatanidza. Unganidza mutema mutema kubva kuDVM kuenda kune yepasi terminal pane harness yekubatanidza yeiyo FRP sensor. Unganidza iyo tsvuku inotungamira kubva kuDVM kuenda kune yekupedzisira magetsi pane harness yekubatanidza yeiyo FRP sensor. Batidza kiyi, injini yakadzimwa. Tarisa zvigadzirwa zvemugadziri; voltmeter inofanirwa kuverenga kana gumi nemaviri volts kana mashanu volts. Kana zvisiri, gadzirisa iyo tambo yemagetsi kana yepasi kana kutsiva iyo PCM.

Kana bvunzo yapfuura ikapfuura, isu tichafanirwa kutarisa waya weshumo. Pasina kubvisa chinobatanidza, fambisa iyo tsvuku voltmeter waya kubva kune yemagetsi waya tambo kune iyo chiratidzo waya waya terminal. Iyo voltmeter inofanirwa kuverengera mashanu volts. Kana zvisiri, gadzirisa tambo yechiratidzo kana kutsiva iyo PCM.

Kana bvunzo dzese dzakapfuura ukaramba uchingogamuchira P0251, zvingangotaridza kuti yakakundikana FRP sensor / peturu yeactuator, kunyangwe iyo PCM yakundikana isingabvisirwe kunze kusvikira iyo FRP sensor / mafuta yakawanda actuator yatsiviwa. Kana iwe usina chokwadi, tsvaga rubatsiro kubva kune anokwanisa mota diagnostician. Kuisa nenzira kwayo, PCM inofanirwa kuve yakagadzirirwa kana kuyerwa pamotokari.
