P0470 - OBD-II Mavuto Code Kufotokozera

Utsi mpweya kuthamanga kachipangizo wonongeka

Kodi cholakwika chimatanthauza chiyani P0470?

Izi ambiri diagnostic code code ikugwira ntchito kwa mitundu yosiyanasiyana ya magalimoto, kuphatikizapo Ford, Mercedes ndi Nissan, ndi mitundu yosiyanasiyana ya injini, kuphatikizapo mafuta ndi dizilo, kuyambira 2005. Zimakhudzana ndi kuthamanga kwa mpweya wotulutsa mpweya ndipo zingasonyeze vuto lamagetsi kapena makina. Nthawi zina imatha kutsagana ndi nambala ya P0471, yomwe imasiyana nthawi ndi mtundu wa kulephera kwa sensor yotulutsa mphamvu. Masitepe okonza amadalira wopanga, mtundu wamafuta ndi mtundu wa waya.

Khodi yamavuto P0470 ndiyofala pamapangidwe osiyanasiyana ndi mitundu yamagalimoto. Zimasonyeza vuto ndi mphamvu ya mpweya wotulutsa mpweya ndipo ikhoza kukhala chifukwa cha mavuto a magetsi kapena makina. Nthawi zina zimatsagana ndi nambala ya P0471, yomwe imasiyana nthawi ya vuto komanso mtundu wa kulephera kwa sensa. Kukonza kungasiyane kutengera wopanga, mtundu wamafuta, ndi mtundu wa waya.

Sensa ya Exhaust Back Pressure (EBP) imakhala ndi gawo lofunikira pakuyezera kuthamanga kwa mpweya wotulutsa mpweya ndipo imalola kuwongolera kwa Exhaust Back Pressure Regulator (EPR) mwa lamulo lochokera ku Engine Control Module (ECM).

Chitsanzo Exhaust Anzanu kuyeza:

Ma Code Othandizira a Exhaust Pressure Sensor Trouble Code:

  • P0471 Exhaust Gas Pressure Sensor "A" Circuit Range/Magwiridwe
  • P0472 Low siginali mlingo mu utsi mpweya kuthamanga sensa dera "A"
  • P0473 Exhaust gas pressure sensor "A" dera lalitali
  • P0474 Exhaust mpweya kuthamanga sensa "A" dera kulephera

Zotheka

Khodi iyi ya P0470 ikhoza kuwoneka pazifukwa izi:

  1. Pali kutsekeka mu chubu pakati pa manifold otopetsa ndi sensor sensor.
  2. Mavuto ndi EGR kapena makina otengera mpweya, kuphatikiza kutulutsa mpweya.
  3. Sensor yolakwika ya exhaust gas pressure sensor.
  4. Zosowa: Kuwonongeka kotheka kwa Powertrain Control Module (PCM), ngakhale sizingatheke.
  5. Pali kutsekeka mu payipi yolumikiza sensor yoponderezedwa ndi zotulutsa zambiri.
  6. Dongosolo lotulutsa mpweya wotulutsa mpweya silikuyenda bwino, zomwe zimatha kutulutsa mpweya.
  7. Sensor yolakwika ya exhaust backpressure sensor.
  8. Mavuto ndi ma waya otsekera a backpressure sensor, monga otsegula kapena mabwalo amfupi.
  9. Kulumikizana kosakwanira kwamagetsi mu exhaust backpressure sensor circuit.

Kodi zizindikiro za cholakwika ndi chiyani? P0470?

Zizindikiro za nambala ya P0470 ndi:

  1. Kuwala kwa Malfunction Indicator Light (MIL), komwe kumadziwikanso kuti cheke injini kuwala, kumabwera.
  2. Kuwoneka kotheka kwa "Check Engine" kuunikira pagawo lowongolera lomwe lili ndi cholakwika chosungidwa mu kukumbukira kwa ECM.
  3. Kutayika kwa mphamvu ya injini.
  4. Kuthekera kuletsa chowongolera mpweya wotulutsa mpweya.

Khodi ya P0470 imaonedwa kuti ndi yofunika kwambiri chifukwa imatha kukhudza momwe galimoto imagwiritsidwira ntchito. Koma imatha kuthetsedwa mosavuta ndikulowetsa kachipangizo kolakwika kagasi kawo.

Zizindikiro za nambala ya P0470 zingaphatikizepo:

  1. Nyali ya injini ya cheki imakhala yoyaka nthawi zonse.
  2. Kusowa mphamvu.
  3. Kukanika kukonzanso fyuluta ya dizilo, zomwe zingapangitse injini kulephera.

Momwe mungadziwire cholakwika P0470?

Njira yabwino yoyambira kuzindikira khodi ya P0470 ndikuwunika za Technical Service Bulletin (TSB) pamapangidwe anu agalimoto. Wopanga atha kupereka zosintha zamapulogalamu (firmware) kuti PCM ikonze vutoli. Kenako, pezani sensor yotulutsa mpweya pagalimoto yanu ndikudula chubu yomwe imayilumikiza ndi njira zambiri zotulutsa mpweya.

Yesani kuchotsa chubu ili kuti muchotse mpweya uliwonse womwe ukuyambitsa P0470 code. Ngati chubu ndi choyera, yang'anani zolumikizira ndi mawaya ngati zawonongeka kapena zadzimbiri. Kenako, yesani mabwalo amagetsi a 5V ndi masensa pogwiritsa ntchito digito volt-ohmmeter (DVOM).

Onetsetsani kuti sensor yakhazikika bwino. Ngati mayesero onse apita, m'malo mwa sensa yotulutsa mpweya wotuluka pangafunike. Ngati code ya P0470 ikupitiriza kuonekera, PCM yolakwika ingakhalenso chifukwa, koma ikhoza kuchotsedwa pambuyo posintha sensa ndikuchita mayesero owonjezera.

Zolakwa za matenda

Zomwe zingayambitse P0470 code

Mukazindikira kachidindo ka P0470, ndikofunikira kuganizira zingapo zomwe zingayambitse khodiyi. M'munsimu muli zinthu zofunika kuziganizira:

  1. Kutsekeka mu chubu kuchokera ku manifold otopetsa kupita ku sensor sensor: Chochitika chimodzi chotheka ndi chakuti carbon imamanga mu dongosolo lotayira, zomwe zingayambitse kutsekeka mu chubu yomwe sensor yokakamiza imalandira chidziwitso. Izi zitha kubweretsa kuwerengedwa kolakwika ndi nambala ya P0470.
  2. Mavuto ndi dongosolo la exhaust gas recirculation (EGR), kutengera mpweya kapena kutulutsa mpweya: Mavuto ndi makina otulutsa mpweya kapena mpweya amatha kusokoneza kupanikizika muzitsulo zotulutsa mpweya ndipo zimayambitsa P0470 code. Kuzindikira kodalirika kwa zigawozi kungakhale sitepe yofunikira.
  3. Kulephera kwa sensor yotulutsa mpweya wotulutsa mpweya: Mphamvu yamagetsi yotulutsa mpweya yokha imatha kulephera kapena kupanga ma siginecha olakwika, zomwe zimapangitsa P0470 code.
  4. Mavuto a Sensor Exhaust Back Pressure (EBP): The exhaust backpressure sensor ndi gawo lofunikira la dongosolo loyang'anira injini ndipo limatha kulumikizidwa ndi code P0470.
  5. Mavuto ndi mawaya ndi kulumikizana ndi magetsi: Mawaya owonongeka, dzimbiri, kapena kulumikizana kolakwika kwa magetsi pakati pa masensa ndi makina owongolera kungayambitse zizindikiro zolakwika ndi code P0470.

Izi zomwe zingayambitse khodi ya P0470 ndizofunikira kuziganizira panthawi ya matenda ndi kukonza kuti muzindikire ndi kukonza gwero la vuto.

Kodi zolakwika ndizovuta bwanji? P0470?

Khodi yamavuto P0470 ikuwonetsa vuto ndi sensa yotulutsa mpweya kapena mphamvu yotulutsa mpweya. Izi zitha kusokoneza magwiridwe antchito a injini, magwiridwe antchito komanso kugwiritsa ntchito mafuta. Ngakhale kuti iyi si vuto lalikulu, ndi vuto lalikulu lomwe lingayambitse mavuto aakulu ngati silinakonzedwe. Ndikofunikira kuti injini yanu izindikiridwe ndikukonzedwa ndi makaniko pomwe code ya P0470 ikuwoneka kuti ikulepheretsa kuwonongeka kwa injini ndikusunga magwiridwe antchito a injini.

Kodi kukonza kungathandize kuthetsa code? P0470?

Kuthetsa nambala ya P0470 kumaphatikizapo njira zingapo, kutengera chomwe chadziwika:

  1. Kuyang'ana Ma Bulletin a Utumiki Waumisiri (TSB): Yambani ndikuyang'ana zambiri m'makalata aukadaulo, omwe angakhale ndi malingaliro opanga kuti athetse vutoli. Wopangayo atha kuwunikira / kuwunikiranso kwa PCM komwe kungathe kuchotsa kachidindo.
  2. Kuwona mphamvu ya exhaust sensor: Lumikizani chojambulira chotulutsa mpweya ndikuwunika ma depositi a kaboni kapena kuwonongeka. Chotsani kapena kusintha sensa ngati kuli kofunikira.
  3. Kuwunika kwa Wiring: Yang'anani m'maso mawaya, yang'anani kuwonongeka, dzimbiri kapena mawaya osweka. Lumikizani zolumikizira ndikuziyeretsa ngati kuli kofunikira.
  4. Kuyang'ana mphamvu ndi ma siginoloji: Pogwiritsa ntchito mita ya digito volt-ohm (DVOM), yang'anani mphamvu za 5V ndi mabwalo azizindikiro akupita ku sensa. Onetsetsani kuti voteji ikugwirizana ndi zomwe wopanga amapanga.
  5. Kuyang'ana pansi: Yang'anani ngati chojambulira cha mpweya wotulutsa mpweya wakhazikika bwino.
  6. Kuyang'ana chubu ndi maulumikizidwe: Yang'anani mosamala chubu cholumikiza turbocharger kuchulukidwe cholowera kuti chatsikira.
  7. Kuchotsa zolakwika: Gwiritsani ntchito scanner ya OBD-II kuti muchotse khodi ya P0470 pa kukumbukira kwa PCM. Pambuyo pake, yendetsani galimotoyo ndikuwona ngati cholakwikacho chikuwonekeranso.
  8. Kusintha kwa sensor: Ngati vutoli silingathe kuthetsedwa ndi njira zina, sinthani makina otulutsa mpweya.
  9. Zotsatira za PCM: Ngati zonse zomwe zili pamwambazi sizithetsa vutoli, pakhoza kukhala vuto ndi PCM. Komabe, njira iyi iyenera kuonedwa ngati njira yomaliza.

Kumbukirani kuti kuzindikira ndi kukonza kuyenera kuchitidwa ndi makaniko oyenerera kapena malo othandizira kuti atsimikizire chomwe chimayambitsa komanso kukonza bwino kwa khodi ya P0470.
