P0259 - OBD-II Mavuto Code Kufotokozera

Mkulu mlingo wa mafuta dosing ulamuliro wa jekeseni mpope B

Kodi cholakwika chimatanthauza chiyani P0259?

Code P0259 limasonyeza mkulu mlingo wa jekeseni mpope ulamuliro metering mafuta (cam/rotor/injector). Izi zimachitika pamene mphamvu yamagetsi pa sensa imakhala pamwamba pa mlingo wotchulidwa (nthawi zambiri kuposa 4,8 V) kwa nthawi yaitali. Izi nthawi zambiri zimakhala chifukwa cha zovuta mumayendedwe amagetsi. Ndikofunikira kuchita diagnostics ndi kukonza kupewa zingakhudze yobereka mafuta ndi injini ntchito.

Izi P0259 code diagnostic imagwira ntchito injini zosiyanasiyana dizilo okonzeka ndi dongosolo OBD-II. Zitha kuchitika mu Ford, Chevy, GMC, Ram, ndi mitundu ina ya Mercedes Benz ndi VW. Komabe, njira zothetsera mavuto zitha kusiyanasiyana kutengera mtundu, mtundu, ndi kasinthidwe kagalimoto.

Pampu ya jakisoni "B" yowongolera mafuta amafuta nthawi zambiri imakhala ndi sensa yotchinga mafuta (FRP) ndi choyendetsa chamafuta ambiri. Sensa ya FRP imasintha kuchuluka kwa mafuta a dizilo omwe amaperekedwa kwa majekeseni kukhala chizindikiro chamagetsi ku powertrain control module (PCM). PCM imagwiritsa ntchito chizindikirochi kuti idziwe kuchuluka kwa mafuta omwe amaperekedwa ku injini malinga ndi momwe zilili panopa.

Code P0259 ikuwonetsa kuti chizindikiro cha FRP sensor sichikugwirizana ndi momwe injini imagwirira ntchito yomwe imasungidwa kukumbukira PCM. Khodi iyi imayang'ananso chizindikiro chamagetsi kuchokera ku sensa ya FRP pamene kiyi imatsegulidwa koyambirira.

Kuti muthe kuthana ndi mavuto, onani buku lokonzekera la mtundu wagalimoto yanu. Njira zitha kusiyanasiyana kutengera wopanga, mtundu wa sensa ya FRP, ndi mtundu wa waya, ndipo zimafunikira kuzindikira mwatsatanetsatane komanso kukonza mayendedwe amagetsi.

Zotheka

Zomwe zimayambitsa nambala ya P0259 zitha kuphatikiza:

  1. Dera lalifupi mu FRP sensor sensor circuit.
  2. Kutayika kwamagetsi kapena kukhazikika kwa sensa ya FRP.
  3. Kulephera kwa sensa ya FRP.
  4. Kulephera kwa PCM (zosatheka).
  5. jekeseni wamafuta otuluka kapena kuwonongeka.
  6. Mavuto ndi mpope mafuta.
  7. Kutaya kwa injini ya vacuum.
  8. Kuwonongeka kwa sensor ya okosijeni.
  9. Mavuto ndi kutuluka kwa mpweya wambiri kapena sensa yochuluka ya mpweya.
  10. Kusalumikizana bwino kwamagetsi.
  11. Kulephera kwa PCM.

Kupeza ndi kukonza mavutowa kumafuna kufufuza komanso mwina kukonza zida zamagetsi ndi makina a galimoto.

Kodi zizindikiro za cholakwika ndi chiyani? P0259?

Zizindikiro za vuto la P0259 zingaphatikizepo izi:

Zizindikiro zonse:

  1. Mphamvu ya injini yotsika komanso magwiridwe antchito ochepa.
  2. Kuyankha kwamphamvu kwamphamvu komanso kuzizira kovutirapo kuyambira.
  3. Kuchepetsa mphamvu yamafuta.
  4. Kuthamanga kwa injini pang'onopang'ono komanso phokoso lowonjezeka.
  5. Kulephera kwa ECM/PCM.
  6. Kuyendetsa injini ndi osakaniza olemera kapena zowonda.
  7. Injini imasokonekera komanso kutayika kwa kuyankha kwamphamvu.
  8. Kutulutsa kwa utsi kuchokera ku injini poyambitsa ndi kuchuluka kwa mpweya.

Zizindikiro zowonjezera:

  1. Kuwala kwa Malfunction indicator Light (MIL) .
  2. Kuchepetsa kwina kwamafuta owonjezera.

Momwe mungadziwire cholakwika P0259?

Kuti muzindikire bwino nambala ya P0259 ndikuthetsa zomwe zimayambitsa, tsatirani izi:

  1. Onani zolemba zaukadaulo (TSB): Yambani powona zidziwitso zaukadaulo zokhudzana ndi galimoto yanu. Vuto lanu likhoza kukhala kale lodziwika ndi kuthetsedwa vuto, ndipo wopanga wapereka njira yoyenera, yomwe ingakupulumutseni nthawi ndi ndalama pofufuza.
  2. Pezani sensa ya FRP: Pezani sensor ya njanji yamafuta (FRP) pagalimoto yanu. Kachipangizo kameneka kamakhala mkati kapena pambali pa mpope wa jekeseni wamafuta ndipo amabowoleredwa ku injini.
  3. Onani cholumikizira ndi mawaya: Yang'anani mosamala cholumikizira ndi mawaya okhudzana ndi sensa ya FRP. Yang'anani zokala, scuffs, mawaya owonongeka, zoyaka kapena pulasitiki yosungunuka.
  4. Yeretsani ndikutumikira cholumikizira: Ngati kuli kofunikira kuyeretsa ma terminals, gwiritsani ntchito chotsukira chapadera chamagetsi ndi burashi yapulasitiki. Pambuyo pake, perekani mafuta amagetsi kumalo okhudzana.
  5. Yang'anani ndi chida chodziwira matenda: Ngati muli ndi chida chojambulira, chotsani ma DTC pamtima ndikuwona ngati nambala ya P0259 ikubwerera. Ngati izi sizichitika, vuto likhoza kukhala ndi maulumikizidwe.
  6. Onani sensa ya FRP ndi dera lake: Kiyi itazimitsidwa, chotsani cholumikizira chamagetsi cha FRP ndikuwunika mphamvu. Lumikizani chiwongolero chakuda cha voltmeter ya digito ku terminal yapansi ya cholumikizira ndi chowongolera chofiyira ku terminal yamagetsi. Yatsani kiyi ndikuwonetsetsa kuti zowerengerazo zikufanana ndi opanga magalimoto (nthawi zambiri 12V kapena 5V). Ngati sichoncho, konzani kapena kusintha mawaya amagetsi kapena pansi, kapena PCM.
  7. Yang'anani chingwe cha chizindikiro: Sunthani chiwongolero chofiyira cha voltmeter kuchokera pagawo lamagetsi kupita ku cholumikizira chingwe cholumikizira. Voltmeter iyenera kuwerenga 5V. Apo ayi, konzani chingwe cha chizindikiro kapena m'malo mwa PCM.
  8. Onani dongosolo lamafuta: Yang'anani thanki yamafuta, mizere yamafuta, ndi fyuluta yamafuta ngati yawonongeka kapena yawonongeka.
  9. Onani kuthamanga kwamafuta: Tengani kuwerengera kwamafuta pamanja panjanji yamafuta ndikufananiza ndi zomwe zimapangidwira. Gwiritsani ntchito makina ojambulira kuti mufananize zowerengerazi ndi zowerengera pamanja.
  10. Onani pampu yamafuta ndi majekeseni: Yang'anani mosamala momwe jekeseni yamafuta ikuwonongeka kapena kutayikira, ndikusintha kapena kukonzanso ngati kuli kofunikira. Kuti muwone momwe jekeseni ikuyendera, gwiritsani ntchito chizindikiro cha Noid ndikuyesa phokoso.
  11. Onani PCM: Onani zolakwika za PCM (module yowongolera injini). Ngakhale iwo sali

Zolakwa za matenda

Kuti muzindikire bwino ndikuthetsa vutoli, njira zotsatirazi ziyenera kutsatiridwa:

  1. Kuzindikira mozama: Ndikofunikira kusanthula mwatsatanetsatane vutolo, kuchotsa kuthekera kwa zinthu zobisika.
  2. Zofunikira zofunika kuziwona: Chidwi kwambiri chiyenera kuperekedwa ku zigawo zotsatirazi:
  • Sefa yamafuta: Yang'anani momwe fyulutayo ilili, chifukwa kutseka kungakhudze kutumiza mafuta.
  • Kuwongolera kwamafuta: Yang'anirani momwe makina owongolera amagwirira ntchito, chifukwa kulephera kwake kungayambitse cholakwika.
  • Pampu yamafuta: Yang'anani momwe pampuyo ilili, chifukwa mapampu olakwika amatha kuyambitsa vutoli.
  • Mizere yamafuta: Yang'anani mizere yamafuta ngati ikutha, zomwe zingayambitse nambala ya P0259.
  • Powertrain Control Module (PCM): Yang'anani PCM kuti isagwire ntchito, ngakhale kuti zochitika zoterezi ndizosowa, zingakhudze dongosolo loperekera mafuta ndikuyambitsa zolakwika.
  • Wiring ndi ma harnesses: Yang'anani mosamala momwe ma waya amagetsi ndi ma harnesses alili, chifukwa mavuto omwe ali nawo amatha kukhala olakwika.

Kukhazikika kokhazikika kwa magawo onse ozindikira matenda ndikuwunika mosamalitsa gawo lililonse lazigawo zomwe zatchulidwazi kudzakuthandizani kudziwa bwino chomwe chimayambitsa cholakwikacho ndikuyamba kuchichotsa.

Kodi kukonza kungathandize kuthetsa code? P0259?

Zina mwa magawo omwe angafunike kusinthidwa mwachangu ndi awa:

  • Fyuluta yamafuta
  • Majekeseni amafuta
  • Mafuta owongolera
