Mayeso a Emissions Alephera ? Konzani 10 Common OBD-II Codes Musanayang'anenso

Magalimoto amakono amadalira dongosolo la On-Board Diagnostics II (OBD-II) kuti liwunikire momwe injini ikugwirira ntchito ndi mpweya. Galimoto yanu ikalephera kuyesa mpweya, doko la OBD-II limakhala chida chanu chabwino kwambiri chodziwira ndi kuthetsa mavuto. Pansipa, tikufotokozera momwe makina ojambulira a OBD-II amagwirira ntchito ndikupereka njira zothetsera mavuto 10 omwe angayambitse kulephera kwa mpweya.

Momwe OBD-II Scanners Imathandizira Kuzindikira Mavuto Otulutsa

  1. Werengani Ma Diagnostic Trouble Codes (DTCs):
    • Makanema a OBD-II amapezanso ma code (mwachitsanzo, P0171, P0420) omwe amalozera kulephera kwadongosolo komwe kumakhudza mpweya.
    • Chitsanzo: AP0420code ikuwonetsa kulephera kwa chosinthira chothandizira.
  2. Live Data Streaming:
    • Yang'anirani data ya sensa ya nthawi yeniyeni (monga mphamvu ya sensa ya okosijeni, kudula kwamafuta) kuti muwone zolakwika.
  3. Chongani "Readiness Monitors":
    • Mayeso otulutsa mpweya amafuna kuti ma monitor onse (mwachitsanzo, EVAP, catalytic converter) akhale "okonzeka." Makana amatsimikizira ngati makina amaliza kudzifufuza okha.
  4. Yendetsani Mafelemu Data:
    • Onaninso zomwe zasungidwa (kuchuluka kwa injini, RPM, kutentha) panthawi yomwe code idayambitsidwa kuti ibwereze ndikuzindikira zovuta.
  5. Chotsani Makhodi ndikukhazikitsanso zowunikira:
    • Pambuyo pokonza, yambitsaninso dongosolo kuti litsimikizire zokonza ndikukonzekera kuyesedwanso.

10 Zizindikiro Zodziwika za OBD-II Zomwe Zimayambitsa Kulephera Kutulutsa

1. P0420/P0430 - Kugwiritsa Ntchito Njira Yothandizira Pansi Pansi Pansi

  • Chifukwa:Kulephera kutembenuza catalytic, sensa ya okosijeni, kapena kutulutsa mpweya.
  • Konzani:
    • Yesani ntchito ya sensa ya oxygen.
    • Yang'anirani ngati kutayikira kwatulutsa.
    • Bwezerani chosinthira chothandizira ngati chawonongeka.

2. P0171/P0174 - Dongosolo Lawonda Kwambiri

  • Chifukwa:Kutuluka kwa mpweya, sensor yolakwika ya MAF, kapena pampu yamafuta ofooka.
  • Konzani:
    • Yang'anani kutuluka kwa vacuum (mapaipi osweka, ma gaskets olowera).
    • Yeretsani / m'malo mwa MAF sensor.
    • Yesani kuthamanga kwamafuta.

3. P0442 - Kutayikira kwakung'ono kwa Evaporative Emission

  • Chifukwa:Chipewa cha gasi chotayirira, paipi ya EVAP yosweka, kapena valavu yotsuka yolakwika.
  • Konzani:
    • Mangitsani kapena sinthani chipewa cha gasi.
    • Yesani dongosolo la EVAP kuti mupeze kutayikira.

4. P0300 - Mosasinthika/Multiple Cylinder Misfire

  • Chifukwa:Ma spark plugs owonongeka, ma coils oyatsira oyipa, kapena kuponderezedwa pang'ono.
  • Konzani:
    • Bwezerani ma spark plugs/makoyilo oyatsira moto.
    • Chitani mayeso a compression.

5. P0401 - Kuthamanga kwa Gasi Wotulutsa (EGR) Kuyenda Kosakwanira

  • Chifukwa:Ndime zotsekeka za EGR kapena valavu ya EGR yolakwika.
  • Konzani:
    • Tsukani mpweya wa carbon kuchokera ku EGR valve ndi ndime.
    • Sinthani valavu ya EGR yokhazikika.

6. P0133 - O2 Sensor Circuit Slow Response (Banki 1, Sensor 1)

  • Chifukwa:Kuwonongeka kwa sensor ya oxygen kumtunda.
  • Konzani:
    • Bwezerani kachipangizo ka oxygen.
    • Yang'anani mawaya awonongeka.

7. P0455 - Kutayikira Kwakukulu kwa EVAP

  • Chifukwa:Paipi ya EVAP yolumikizidwa, chitoliro chamalala cholakwika, kapena thanki yamafuta yomwe yawonongeka.
  • Konzani:
    • Onani mapaipi a EVAP ndi zolumikizira.
    • Bwezerani chitini cha makala ngati chasweka.

8. P0128 - Kuwonongeka kwa Thermostat Yozizira

  • Chifukwa:Thermostat idatsekedwa, zomwe zidapangitsa injini kuzizira kwambiri.
  • Konzani:
    • Bwezerani chotenthetsera.
    • Onetsetsani kuti madzi ozizira akuyenda bwino.

9. P0446 - Kuwonongeka kwa EVAP Vent Control Circuit

  • Chifukwa:Kulowera kolakwika kwa solenoid kapena chingwe chotsekeka cholowera.
  • Konzani:
    • Yesani mpweya wa solenoid.
    • Chotsani zinyalala pamzere wolowera.

10. P1133 – Fuel Air Metering Correlation (Toyota/Lexus)

  • Chifukwa:Kusalinganika kwa mpweya / mafuta chifukwa cha sensor ya MAF kapena kutayikira kwa vacuum.
  • Konzani:
    • Sensa yoyera ya MAF.
    • Yang'anirani ngati mpweya watsikira popanda mita.

Njira Zowonetsetsa Kuti Mayeso a Emissions Apambana

  1. Dziwani Makhodi Poyambirira:Gwiritsani ntchito scanner ya OBD-II kuti muzindikire zovuta masabata angapo musanayesedwe.
  2. Konzani Mwachangu:Yambitsani zovuta zazing'ono (mwachitsanzo, kutuluka kwa mpweya) zisanayambitse ma code ovuta kwambiri.
  3. Kumaliza Koyendetsa:Pambuyo pochotsa ma code, malizitsani kuzungulira pagalimoto kuti mukonzenso zowunikira.
  4. Jambulanitu Mayeso:Onetsetsani kuti palibe ma code omwe abwerera ndipo oyang'anira onse ali "okonzeka" asanaunike.

Malangizo Omaliza

  • Invest in ascanner yapakatikati ya OBD-II(mwachitsanzo, iKiKin) kuti muwunike mwatsatanetsatane ma code.
  • Pamakhodi ovuta (mwachitsanzo, kulephera kosinthira kothandizira), funsani katswiri wamakaniko.
  • Kusamalira nthawi zonse (ma spark plugs, zosefera mpweya) kumalepheretsa zinthu zambiri zokhudzana ndi mpweya.

Pogwiritsa ntchito luso la sikani yanu ya OBD-II, mutha kuzindikira ndikukonza zovuta zomwe zimatulutsa mpweya wabwino, ndikuwonetsetsa kuyenda bwino pakuwunika kwanu kotsatira!
