Qhov txhaum cai txhais li cas P0452?

Teeb meem code P0452 cuam tshuam rau evaporative emission (EVAP) system. Koj lub tsheb tau nruab nrog lub roj tank siab sensor uas muab cov ntaub ntawv rau lub cav tswj lub tshuab computer (ECM). Cov cai no yog ib qho kev kuaj mob dav dav rau OBD-II cov tsheb nruab, uas txhais tau hais tias nws siv rau feem ntau thiab cov qauv ntawm cov tsheb tsim xyoo 1996 thiab tom qab ntawd.

Thaum koj ECM pom qhov txawv txav tsis zoo, uas tuaj yeem qhia txog teeb meem nrog EVAP system, nws tsim P0452 code. Qhov no sensor yog siv los saib xyuas cov roj vapor siab hauv lub tank roj. Lub sensor tuaj yeem ntsia tau sib txawv hauv ntau hom tsheb. Piv txwv li, nws yuav nyob rau hauv ib tug roj kab txuas los ntawm cov roj module nyob rau sab saum toj ntawm lub tank roj, los yog ncaj qha rau saum lub tank. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias qhov sensor no feem ntau yog siv rau kev tswj emissions thiab tsis muaj kev cuam tshuam ncaj qha rau kev ua haujlwm ntawm lub cav.

P0452 code tej zaum yuav zoo sib xws rau ntau lub tsheb, tab sis lawv yuav muaj qhov sib txawv ntawm cov khoom siv sensor. Piv txwv li, lub sensor ntawm ib lub tsheb yuav tso tawm 0,1 volts ntawm qhov zoo tank siab thiab mus txog 5 volts ntawm qhov tsis zoo siab (nqus), thaum nyob rau lwm lub tsheb qhov voltage yuav nce raws li zoo tank siab nce.

Associated evaporative emissions system teeb meem cov lej suav nrog P0450, P0451, P0453, P0454, P0455, P0456, P0457, P0458, thiab P0459.

Thov nco ntsoov tias nws yog ib qho tseem ceeb uas yuav tsum tau kuaj xyuas kom raug thiab daws qhov teeb meem cuam tshuam nrog P0452 code kom ntseeg tau tias kev ua haujlwm ruaj khov thiab zoo ib puag ncig ntawm evaporative emission control system.

Tej zaum ua rau

Tej yam ua tau ntawm tus lej P0452 suav nrog:

  1. Malfunction ntawm roj tank siab sensor.
  2. Qhib los yog luv Circuit Court nyob rau hauv lub sensor thaiv.
  3. Kev sib txuas hluav taws xob tsis raug rau FTP sensor.
  4. Kev tawg lossis tawg ntawm cov kab hluav taws xob ua rau lub tshuab nqus tsev.
  5. Qhov zoo ntawm chav dej ua rau lub tank tawg lossis tawg.
  6. Clogged kab hauv evaporative emission control (EVAP) system.
  7. Pa roj gasket nyob rau hauv lub roj twj tso kua mis module.
  8. Loose gas cap, uas tuaj yeem ua rau lub tshuab nqus tsev vacuum.
  9. Pinched chav kab.

Tsis tas li ntawd, P0452 code tej zaum yuav yog vim muaj kev ua haujlwm tsis zoo ntawm Emissions Evaporative Control (EVAP) siab sensor lossis teeb meem nrog lub ntsuas hluav taws xob.

Txoj cai no qhia txog cov teeb meem uas muaj feem cuam tshuam nrog kev tswj hwm evaporative emission control (EVAP) thiab yuav tsum tau kuaj xyuas thiab kho kom ntseeg tau tias lub tshuab ua haujlwm tau zoo.

Cov tsos mob ntawm tus lej yuam kev yog dab tsi? P0452?

Tsuas yog kos npe uas qhia tias tus lej P0452 yog thaum qhov kev pabcuam lossis kuaj lub teeb lub cav los. Nyob rau hauv tsawg zaus, ib tug hnov ​​tsw ntawm roj vapor tej zaum yuav tshwm sim.

Yuav ua li cas kuaj tau tus lej txhaum P0452?

Qhov teeb meem no yuav tsum tsis muaj kev saib xyuas vim qhov chaw ntawm lub sensor thiab cov cuab yeej xav tau los kuaj xyuas qhov teeb meem. Lub sensor nyob rau sab saum toj ntawm cov roj tank sab hauv lossis nyob ib sab ntawm lub tshuab hluav taws xob roj twj tso kua mis.

Thawj qhov koj yuav tsum tau ua yog tshuaj xyuas tag nrho cov ntawv xov xwm pabcuam rau koj lub tsheb. Qhov no yog ib qho kev xyaum zoo raws li lawv yuav muaj cov lus qhia.

Qhov thib ob, koj yuav pom cov teeb meem uas cov neeg siv khoom ntsib nrog cov qauv no thiab cov kauj ruam pom zoo los daws lawv.

Thaum kawg, cov tsheb feem ntau muaj kev tiv thaiv ntev heev ntawm cov khoom siv hluav taws xob, xws li 100 mais, yog li nws yuav yog qhov zoo los xyuas koj qhov warranty thiab coj kom zoo dua yog tias koj muaj.

Txhawm rau nkag mus rau lub sensor, koj yuav tsum tshem lub tank roj. Txoj hauj lwm nyuaj thiab me ntsis txaus ntshai no yog qhov zoo tshaj plaws rau tus kws tshaj lij nrog lub elevator.

Hauv ntau dua 75 feem pua ​​​​ntawm cov neeg mob, ib tus neeg tsis siv sijhawm los "latch" lub hau roj. Thaum lub hau roj tsis kaw nruj nreem kaw, lub tank tsis tuaj yeem tsim lub tshuab nqus tsev nqus thiab vapor siab tsis nce, ua rau cov input voltage qis thiab P0452 code los teeb. Qee lub tsheb tam sim no muaj lub teeb "check fuel cap" ntawm lub dashboard los qhia rau koj thaum koj xav tau rov kaw lub hau.

Koj tuaj yeem tshawb xyuas cov kav dej los ntawm sab saum toj ntawm lub tank roj los ntawm hauv qab lub tsheb txhawm rau saib seb puas muaj kab tawg lossis khoov. Muaj peb lossis plaub kab khiav ntawm sab saum toj ntawm lub tank ua rau tus neeg tsav tsheb sab ncej rail uas tuaj yeem kuaj xyuas. Tab sis yog tias lawv yuav tsum tau hloov, lub tank yuav tsum tau qis dua.

Tus kws tshaj lij yuav siv cov cuab yeej kuaj mob tshwj xeeb uas yuav kuaj xyuas lub sensor hauv lub tsheb, nrog rau tag nrho cov kab thiab lub tank siab, kho qhov kub, av noo thiab qhov siab. Nws tseem yuav qhia rau tus kws tshaj lij yog tias cov kab hluav taws xob ua haujlwm tsis raug thiab yog tias cov kev sib txuas hluav taws xob ua haujlwm tau zoo.

Kev kuaj mob yuam kev

Qhov yuam kev hauv kev kuaj mob P0452 tuaj yeem ua rau tsis raug txhais lus ntawm cov ntaub ntawv roj tank siab sensor thiab, vim li ntawd, hloov cov khoom tsis raug. Nws yog ib qho tseem ceeb uas yuav tau ua qhov kev kuaj mob kom tsis txhob muaj cov nqi tsim nyog thiab ua kom ntseeg siab daws qhov teeb meem. Nov yog qee qhov yuam kev uas yuav tsum zam thaum kuaj pom tus lej P0452.

  1. Unchecked roj cap: Ib qho laj thawj heev ntawm P0452 code yog lub hau roj xoob. Ua ntej ua qhov kev kuaj mob nyuaj, xyuas kom tseeb tias lub tank lub hau kaw kom zoo thiab tsim lub tshuab nqus tsev. Qee lub tsheb muaj lub teeb ntawm lub dashboard uas ceeb toom koj yog tias lub npog tsis raug.
  2. Tsis quav ntsej Service Bulletins: Cov neeg tsim khoom tuaj yeem tshaj tawm cov ntawv tshaj tawm txog cov teeb meem P0452. Kev tshuaj xyuas lawv tuaj yeem pab koj nkag siab yog tias muaj teeb meem paub txog koj tus qauv tsheb.
  3. Qhov muag tsis pom kev hloov pauv: Teeb meem code P0452 tsis yog ib txwm muaj feem xyuam rau cov roj siab sensor. Hloov cov sensor no yam tsis tau kuaj pom thawj zaug nws yuav ua rau cov nqi tsis tsim nyog. Nws yog ib qho tseem ceeb los xyuas tag nrho cov khoom sib txuas xws li cov xov hlau, hoses thiab kev sib txuas ua ntej hloov lub sensor.

Tshem tawm tag nrho cov teeb meem saum toj no thiab kuaj xyuas lawv tuaj yeem txuag koj ntau lub sijhawm thiab nyiaj txiag thaum daws teeb meem P0452 code ntawm koj lub tsheb.

Txoj cai txhaum loj npaum li cas? P0452?

Teeb meem code P0452 feem ntau tsis loj heev thiab tsis cuam tshuam rau kev nyab xeeb ntawm kev tsav tsheb, tab sis tuaj yeem ua rau muaj teeb meem me me thiab kev lag luam roj.

Kev kho dab tsi yuav pab tshem tawm cov cai? P0452?

Cov kauj ruam hauv qab no yuav tsum tau kho kom daws tau P0452 code:

  1. Hloov lub siab sensor hauv lub tank roj.
  2. Tshawb xyuas thiab hloov cov kab hluav taws xob sensor yog tias muaj kev tawg lossis luv luv.
  3. Tshawb xyuas thiab kho cov kev sib txuas hluav taws xob rau FTP sensor.
  4. Hloov lossis kho cov kab tawg tawg lossis tawg.
  5. Disassemble lub tank roj los hloov cov roj twj tso kua mis module foob (yog tias tsim nyog).
  6. Xyuas lub gas tank cap kom nruj.
  7. Kos thiab, yog tias tsim nyog, hloov cov kav dej.

Nws raug nquahu kom kuaj xyuas thiab kho los ntawm tus kws tshaj lij uas tsim nyog, vim tias kev kho tsis raug yuav ua rau muaj teeb meem ntxiv.
