26.05.2022 /

P0496 – OBD-II Teeb meem Code Technical Description

Cov teeb meem code qhia tau hais tias muaj teeb meem nrog kev tshem tawm hauv cov evaporative emission system.

Qhov txhaum cai txhais li cas P0496?

Teeb meem code P0496 qhia txog qhov teeb meem nrog kev tshem tawm hauv cov evaporative emission system. Qhov no txhais tau hais tias lub tshuab nqus tsev ntau dhau tau muab nkag rau hauv evaporative emission system, uas tuaj yeem ua rau muaj roj ntau thaum ntxuav. Yog tias lub tshuab nqus tsev ntau dhau ua rau hauv lub tshuab evaporative emission, code P0496 yuav tshwm sim.

Kev txhaum cai P0496.

Tej zaum ua rau

Qee qhov laj thawj rau P0496 teeb meem code:

  • Qhov tsis zoo evaporative evacuation valve (EVAP).
  • Leak nyob rau hauv cov roj vapor rov qab system.
  • Malfunction ntawm lub tshuab nqus tsev vacuum los yog lub tshuab nqus tsev sensor.
  • Txhim kho tsis raug lossis puas lub tank roj.
  • Teeb meem nrog cov khoom siv hluav taws xob ntawm evaporative emission system.
  • Kev ua haujlwm tsis raug ntawm lub siab sensor hauv cov roj vapor rov qab system.
  • Txhim kho tsis raug lossis puas lub tank roj.

Cov tsos mob ntawm tus lej yuam kev yog dab tsi? P0496?

Cov tsos mob rau DTC P0496 yuav txawv nyob ntawm seb qhov ua rau thiab qhov xwm txheej ntawm lub tsheb:

  • Lub Check Engine teeb ntawm lub ntsuas vaj huam sib luag los rau.
  • Cov ntxhiab tsw txawv txawv hauv lossis ib ncig ntawm lub tsheb.
  • Lub cav ua haujlwm tsis zoo, suav nrog kev ua haujlwm tsis zoo lossis tsis muaj zog.
  • Kev siv roj ntau ntxiv.
  • Cov suab tsis zoo los yog tsis tau piav qhia los ntawm cov roj tank lossis thaj chaw evaporative system.
  • Poob roj siab.
  • Deterioration nyob rau hauv engine kev ua tau zoo.

Txawm li cas los xij, nws tsim nyog sau cia tias cov tsos mob no tuaj yeem qhia tau lwm yam teeb meem nrog lub tsheb, yog li nws raug nquahu kom ua qhov kev kuaj mob txhawm rau txheeb xyuas qhov ua rau.

Yuav ua li cas kuaj tau tus lej txhaum P0496?

Txhawm rau kuaj xyuas DTC P0496, cov kauj ruam hauv qab no raug pom zoo:

  1. Txheeb xyuas Lub Teeb Tsav Tsheb: Xyuas kom tseeb tias lub teeb Check Engine tiag tiag los. Siv OBD-II scanner nyeem cov teeb meem code thiab tau txais cov ntaub ntawv ntxiv.
  2. Xyuas cov roj theem: Xyuas kom tseeb tias cov roj theem hauv lub tank yog nyob rau theem pom zoo. Qib roj tsawg tuaj yeem ua rau tsis txaus siab nyob rau hauv evaporative emission system.
  3. Kev soj ntsuam: Tshawb xyuas lub tank roj, cov kab roj thiab cov kev sib txuas rau kev xau lossis kev puas tsuaj.
  4. Txheeb xyuas qhov evaporative tswj valve (CCV): Txheeb xyuas qhov xwm txheej ntawm cov roj vapor tswj valve kom xau lossis puas. Xyuas kom nws kaw kom raug thiab qhib thaum xav tau.
  5. Tshawb xyuas cov roj av ntes (EVAP) system: Tshawb xyuas cov khoom siv hluav taws xob hauv hluav taws xob xws li cov twj tso kua mis siab, cov li qub thiab cov khoom sib khi rau kev puas tsuaj lossis cov xau.
  6. Kev kuaj mob siv OBD-II scanner: Siv OBD-II scanner los nyeem cov ntaub ntawv ntxiv xws li evaporative emission system kev ua tau zoo thiab lub zog siab.
  7. Tshawb xyuas kev sib txuas hluav taws xob: Tshawb xyuas cov kev sib txuas hluav taws xob thiab cov xov hlau txuas nrog cov evaporative emission system rau kev puas tsuaj lossis oxidation.
  8. Xyuas cov sensors: Txheeb xyuas cov haujlwm ntawm cov sensors cuam tshuam nrog lub evaporative emission system, xws li lub siab sensor, kub sensor thiab lwm yam, rau kev puas tsuaj lossis ua haujlwm tsis zoo.
  9. Ua kev kuaj lub tshuab nqus tsev: Ua cov kev ntsuam xyuas lub tshuab nqus tsev kom paub meej tias kev ua haujlwm zoo ntawm lub tshuab nqus tsev tswj.

Yog tias muaj kev ua haujlwm tsis zoo lossis tsis paub meej txog kev kuaj mob, nws raug nquahu kom koj hu rau tus kws kho tsheb tsim nyog lossis chaw pabcuam rau kev kuaj mob ntxiv thiab kho.

Kev kuaj mob yuam kev

Thaum kuaj pom DTC P0496, cov teeb meem hauv qab no yuav tshwm sim:

  • Kev ntsuas tsis txaus ntawm qhov evaporative vapor rov qab (EVAP) system: Yog tias kev kuaj mob tsuas yog tsuas yog nyeem cov cai txhaum cai xwb, yam tsis tau kuaj xyuas tag nrho EVAP cov txheej txheem, cov xwm txheej uas tuaj yeem ua rau qhov txhaum yuav ploj mus.
  • Kev txhais tsis raug ntawm OBD-II scanner cov ntaub ntawv: Qee qhov tsis tau muab los ntawm OBD-II scanner yuav raug txhais yuam kev. Qhov no tuaj yeem ua rau misdiagnosis thiab hloov qhov tsis tsim nyog.
  • Tsis quav ntsej kev txheeb xyuas lub cev ntawm cov khoomNco tseg: Kev cia siab ib leeg ntawm OBD-II cov ntaub ntawv scanner yam tsis tau kuaj xyuas lub cev EVAP cov khoom hauv lub cev tuaj yeem ua rau ploj lossis puas tsuaj uas yuav tsis pom ntawm lub tshuab luam ntawv.
  • Tsis saib xyuas kev sib txuas hluav taws xob: Kev kuaj xyuas tsis raug lossis tsis quav ntsej txog qhov xwm txheej ntawm kev sib txuas hluav taws xob thiab cov xov hlau cuam tshuam nrog EVAP system tuaj yeem ua rau muaj teeb meem cuam tshuam txog kev sib cuag tsis zoo lossis luv luv.
  • OBD-II scanner malfunction: Muaj tsawg zaus, kev txhais lus yuam kev ntawm tus lej teeb meem yuav yog vim muaj teeb meem nrog OBD-II scanner nws tus kheej lossis nws cov software.

Txhawm rau tiv thaiv cov teeb meem no, nws raug nquahu kom siv cov kev kuaj mob dav dav, suav nrog kev kuaj xyuas lub cev, tshuaj xyuas OBD-II cov ntaub ntawv scanner, kuaj xyuas cov hluav taws xob sib txuas thiab xov hlau, thiab hu rau tus kws tshaj lij yog tias tsim nyog.

Txoj cai txhaum loj npaum li cas? P0496?

Teeb meem code P0496, uas qhia txog kev tshem tawm cov teeb meem nyob rau hauv evaporative emission control (EVAP) system, feem ntau tsis yog qhov tseem ceeb lossis loj heev. Txawm li cas los xij, tsis quav ntsej nws tuaj yeem ua rau kev ua haujlwm tsis zoo ntawm cov roj vapor rov qab ua haujlwm, uas tuaj yeem ua rau muaj kev puas tsuaj rau ib puag ncig kev ua haujlwm ntawm lub tsheb thiab nce emissions ntawm cov khoom tsis zoo rau hauv qhov chaw.

Txawm hais tias qhov cuam tshuam tam sim ntawd ntawm kev ua haujlwm ntawm lub tsheb thiab kev nyab xeeb feem ntau yog tsawg, nws raug pom zoo tias qhov teeb meem yuav tsum tau daws sai li sai tau kom tsis txhob muaj teeb meem ntxiv nrog rau cov evaporative emission tswj system thiab ua rau muaj kev puas tsuaj rau lwm yam khoom hauv lub tsheb. Tsis tas li ntawd, qhov teeb meem EVAP tuaj yeem ua rau lub tsheb ua tsis tau qhov kev ntsuas emission nyob rau hauv qee thaj tsam, uas tuaj yeem ua rau raug nplua lossis lub tsheb tsis siv tau ib ntus ntawm txoj kev.

Kev kho dab tsi yuav daws tau tus lej P0496?

Kev daws teeb meem DTC P0496 yuav suav nrog cov kauj ruam kho hauv qab no:

  1. Tshawb xyuas thiab hloov cov roj poob valve (FTP) lossis evaporative tswj valve (EVAP).
  2. Ntxuav los yog hloov cov lim roj carbon ntawm cov roj vapor rov qab system.
  3. Tshawb xyuas thiab hloov lub tshuab nqus tsev hoses thiab cov raj cuam tshuam nrog cov roj vapor rov ua haujlwm.
  4. Xyuas thiab ntxuav lub Idle Air Control Valve (IAC) thiab Intake Air Control Valve (PCV).
  5. Tshawb xyuas thiab ntxuav lub tank roj thiab nws lub hau.
  6. Tshawb xyuas thiab hloov kho PCM (lub cav tswj module) software (firmware) los daws cov teeb meem software.

Txij li vim qhov ua rau P0496 code yuav txawv, nws raug nquahu kom koj hu rau tus kws kho tsheb lossis chaw pabcuam rau kev kuaj mob kom raug thiab txiav txim siab txog kev kho kom zoo.
