P0458 EVAP Purge Control Valve Circuit Court qis

P0458 – OBD-II Teeb meem Code Technical Description

Tsawg teeb liab theem nyob rau hauv evaporative emission system ntxuav tswj valve Circuit Court

Qhov txhaum cai txhais li cas P0458?

Ntawm cov tsheb nrog evaporative emissions control (EVAP) systems, lub cav rub cov roj vapor ntau dhau los ntawm lub tank roj los tiv thaiv emissions thiab txo kev cuam tshuam ib puag ncig. EVAP system suav nrog ntau yam khoom, suav nrog cov roj tank, charcoal canister, tank siab sensor, ntxuav valve, thiab lub tshuab nqus tsev hoses. Thaum lub cav khiav, cov khoom no ua haujlwm ua ke los tiv thaiv cov roj vapors los ntawm kev khiav tawm.

Thaum lub cav pib, lub qhov dej huv ntawm lub canister qhib, tso cai rau cov roj vapor nkag mus rau hauv lub tshuab nqus tsev manifold siv lub tshuab nqus tsev. Qhov no txhim kho cov roj / cua sib tov. Lub siab sensor nyob rau hauv lub tank saib xyuas kev hloov siab thiab thaum lub kaw lus mus txog lub xeev xav tau, ob lub valve kaw, tiv thaiv vapor los ntawm kev khiav tawm. PCM (lub cav tswj module) lossis ECM (powertrain control module) tswj cov txheej txheem no.

Code P0458 qhia txog cov teeb meem hauv EVAP system ntsig txog kev tswj lub valve. Thaum OBD-II scanner pom cov cai no, nws qhia tias tsis tshua muaj hluav taws xob hauv lub valve Circuit Court.

Tej zaum ua rau

Teeb meem code P0456 tej zaum yuav tshwm sim los ntawm cov hauv qab no:

1. Fuse los yog relay muaj qhov tsis zoo.
2. Lub purification valve yog faulty.
3. Faulty EVAP ntxuav solenoid tswj.
4. Teeb meem ntawm lub cev muaj zog hlau, xws li tawg los yog tawg nyob ntawm tej los yog luv luv Circuit Court.
5. Qhib lossis luv Circuit Court nyob rau hauv lub purge tswj solenoid.
6. Kev ua haujlwm tsis zoo ntawm PCM / ECM (lub cav lossis kis tau tus mob tswj module).

Qee qhov xwm txheej, cov cai no yuav tshwm sim los ntawm kev teeb tsa roj tsis raug. Txawm li cas los xij, muaj teeb meem loj dua tuaj yeem ua tau, xws li:

• Lub purge tswj solenoid yog faulty.
• Lub thawv thee (coal canister) puas, txhaws lossis faulty.
• Faulty lub tshuab nqus tsev hoses.
• Faulty fuel steam kab.
• Faulty siab / ntws sensor.
• Qhib lossis luv Circuit Court hauv EVAP tshem tawm tswj cov xov hlau solenoid.
• Kev puas tsuaj, corroded, xoob, qhib los yog luv luv hluav taws xob Cheebtsam nyob rau hauv EVAP purge tswj valve Circuit Court, nrog rau cov xov hlau thiab connectors.
• Txheeb xyuas qhov ua haujlwm tsis zoo ntawm EVAP tshem tawm solenoid valve.
• Ib qho qhib lossis luv luv hauv evaporative emission control (EVAP) tshem tawm solenoid valve tswj Circuit Court.

Cov tsos mob ntawm tus lej yuam kev yog dab tsi? P0458?

Feem ntau, thaum muaj P0458 code tam sim no, yuav tsis muaj lwm yam tsos mob tshwj tsis yog lub teeb pom kev zoo ntawm lub teeb pom kev tsis zoo (MIL) lossis Lub Teeb Lub Teeb / Kev Pabcuam Lub Cav Tsis ntev. Cov cai no kuj tseem tuaj yeem nrog rau lwm cov teeb meem code hauv EVAP emission control system. Muaj tsawg zaus, cov pa roj tsw qab thiab / lossis txo qis ntawm cov roj yuav tshwm sim.

Yuav ua li cas kuaj tau tus lej txhaum P0458?

Kev kuaj xyuas tus lej P0458 pib los ntawm kev kuaj xyuas cov ntawv xov xwm kev pabcuam (TSBs) uas siv rau koj lub tsheb kom txiav txim siab txog cov teeb meem paub. Qhov no yog ua raws li kev soj ntsuam pom ntawm cov xov hluav taws xob thiab cov khoom siv rau kev puas tsuaj, luv Circuit Court lossis corrosion.

Yog tias qhov teeb meem tsis daws tau, tus kws kho tsheb yuav xav kuaj xyuas tias lub hau roj tau teeb tsa kom raug, vim qhov no tuaj yeem yog qhov laj thawj yooj yim rau P0458 code. Tom qab ntawd, cov cai yuav tsum tau muab tshem tawm thiab lub kaw lus rov xyuas dua.

Yog tias tus lej rov qab los, koj tus kws kho tsheb yuav tsum ua kom paub meej ntxiv ntawm EVAP purge tswj valve Circuit Court. Qhov no yuav suav nrog kev kuaj xyuas hluav taws xob ua haujlwm ntawm kev tshem tawm cov tswj solenoid thiab cov pins txuas, nrog rau kev kuaj xyuas PCM / ECM cov lus txib kom qhib EVAP system.

Kev kuaj mob yuam kev

Teeb meem code P0458 muaj feem xyuam rau evaporative emission control (EVAP) system thiab qhia txog cov teeb meem nrog rau kev tshem tawm valve. Txawm hais tias txoj cai no tsis yog qhov tseem ceeb rau kev nyab xeeb ntawm kev tsav tsheb tam sim, nws yuav tsum tau saib xyuas thiab kho kom raws sijhawm.

Ua ntej ntawm tag nrho cov, P0458 tuaj yeem ua rau muaj kev cuam tshuam me me hauv kev siv roj. Kev kho tsis tiav ntawm cov roj vapors tuaj yeem ua rau poob ntawm cov khoom siv roj muaj txiaj ntsig thiab nce emissions ntawm cov khoom tsis zoo rau hauv qhov chaw, uas tsis yog kev coj ua ib puag ncig. Tsis tas li ntawd, yog tias tus lej P0458 rov tshwm sim dua, kev kuaj mob ntxiv yuav tsum tau ua kom pom thiab kho cov teeb meem EVAP hnyav dua uas tuaj yeem cuam tshuam rau lub tsheb qhov kev ntseeg siab thiab kev ua haujlwm ntev.

Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias tsis quav ntsej qhov yuam kev no tuaj yeem ua rau muaj kev cuam tshuam ntau dua rau ib puag ncig thiab cov nqi roj hauv lub sijhawm. Yog li, nws raug nquahu kom koj muaj kev kuaj xyuas tus kws tshaj lij thiab daws P0458 code tam sim kom tswj tau qhov kev ua tau zoo ntawm evaporative emission control system thiab txo qhov tsis zoo ntawm ib puag ncig thiab kev lag luam roj.

Txoj cai txhaum loj npaum li cas? P0458?

Teeb meem code P0458 tsis yog qhov tseem ceeb, tab sis yuav tsum tau ua tib zoo saib vim nws tuaj yeem ua rau cov roj tsis zoo thiab emissions.

Kev kho dab tsi yuav pab tshem tawm cov cai? P0458?

Txhawm rau daws qhov yuam kev P0458, cov kauj ruam kho hauv qab no raug pom zoo:

1. Tshawb xyuas thiab hloov qhov kev tswj xyuas lub valve: Thawj kauj ruam yog los xyuas qhov xwm txheej thiab kev ua haujlwm ntawm kev tshem tawm valve. Yog tias lub valve tsis ua haujlwm zoo, nws yuav tsum tau hloov.
2. Tshawb xyuas thiab kho cov kev sib txuas hluav taws xob: Tshawb xyuas cov kev sib txuas hluav taws xob, cov xov hlau thiab cov khoom sib txuas hauv lub tshuab ntxuav lub valve. Hloov lossis kho cov xov hlau puas lossis tawg.
3. Kev kuaj xyuas thiab hloov lub purge tswj solenoid: Yog tias pom tias muaj kev ua haujlwm tsis zoo nrog kev tshem tawm cov tswj solenoid, nws yuav tsum tau hloov nrog ib qho tshiab thiab ua haujlwm.
4. Tshawb xyuas lub tshuab nqus tsev hoses thiab kev sib txuas: Ua tib zoo tshuaj xyuas lub tshuab nqus tsev hoses thiab kev sib txuas hauv EVAP system. Hloov cov hoses puas los yog txhaws.
5. Xyuas thiab hloov lub siab / ntws sensor: Tshawb xyuas lub siab lossis roj ntws sensor hauv EVAP thiab hloov nws yog tias tsim nyog.
6. PCM/ECM Diagnostics: Yog tias lwm cov khoom siv ua haujlwm tau zoo tab sis P0458 code tseem tshwm sim, tej zaum yuav muaj teeb meem nrog PCM / ECM. Ua kev kuaj mob ntxiv thiab hloov PCM / ECM yog tias tsim nyog.

Tom qab ua tiav cov kev kho no, P0458 code yuav tsum raug daws. Txawm li cas los xij, nws tseem pom zoo kom koj EVAP system kuaj xyuas kom nws ua haujlwm tau zoo thiab zam cov teeb meem yav tom ntej.
