OBD-II DTC Cov Ntaub Ntawv

Roj vapor rov qab system Low flow control diaphragm

Qhov no txhais li cas?

Qhov no yog generic diagnostic teeb meem code (DTC) thiab feem ntau yog siv rau OBD-II tsheb uas muaj ib tug EVAP system uas siv ib tug leak detection system. Qhov no yuav suav nrog tab sis tsis txwv rau Toyota, Scion, GM, Chevrolet, Hyundai, Pontiac, Volvo, thiab lwm yam. Raws li qee cov lus ceeb toom, cov cai no zoo li muaj ntau yam ntawm Toyota hom tsheb. Txawm hais tias feem ntau, cov kauj ruam kho qhov tseeb yuav txawv nyob ntawm lub xyoo ntawm kev tsim, ua, qauv thiab kev teeb tsa kev sib kis.

PCM tau kuaj pom qhov tsis sib xws hauv EVAP tswj diaphragm thaum P043E code khaws cia hauv koj lub tsheb OBD-II. Nyob rau hauv cov ntaub ntawv no, ib tug tsawg flow condition tau qhia.

Lub EVAP system yog tsim los cuab cov roj vapors (los ntawm lub tank roj) ua ntej lawv tawm mus rau hauv qhov chaw. EVAP system siv lub vented reservoir (feem ntau hu ua lub kaus poom) khaws cov vapors ntau dhau mus txog thaum lub cav ua haujlwm raws li qhov tsim nyog kom hlawv nws zoo tshaj plaws.

Lub siab (tsim los ntawm kev khaws cov roj) ua zoo li lub tshuab nqus tsev, yuam cov vapors kom khiav tawm ntawm cov hlab thiab nws thiaj li mus rau hauv lub kaus poom. Cov pa roj carbon monoxide muaj nyob rau hauv lub kaus mom absorbs roj vapors thiab tuav lawv tso tawm thaum lub sijhawm.

Ntau cov qauv qhib, lub twj tso kua mis txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm engine bay) yog ib feem ntawm EVAP system.

Lub tshuab nqus tsev yog siv los ntawm EVAP system los rub cov roj vapors (los ntawm cov thee tank thiab los ntawm cov kab) mus rau hauv cov khoom noj khoom haus, uas lawv tuaj yeem hlawv ntau dua li qhov cua. Lub PCM hluav taws xob tswj xyuas lub valve / solenoid, uas yog lub rooj vag ntawm EVAP system. Nws yog lub luag haujlwm rau kev tswj lub tshuab nqus tsev ntawm qhov nkag mus rau EVAP canister kom cov roj vapors tsuas yog rub mus rau hauv lub cav thaum cov xwm txheej zoo tagnrho rau kev sib xyaw kom zoo tshaj plaws ntawm cov roj siab vapor.

Qee lub tshuab EVAP siv lub tshuab hluav taws xob xaim hluav taws xob txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txheeb xyuas qhov xau / ntws. Leak detection reference qhov tuaj yeem muab tso rau ntawm ib qho taw tes lossis ntau lub ntsiab lus thoob plaws hauv EVAP system. Leak detection reference ports feem ntau yog linear kom ntws tau raug ntsuas kom raug thaum lub tshuab nqus dej nqus dej tau qhib. Lub PCM siv cov khoom siv los ntawm EVAP siab thiab ntws sensors ua ke nrog cov ntaub ntawv siv chaw nres nkoj / cov chaw nres nkoj rau kev kuaj pom los txiav txim seb qhov dej xau pom tau ua haujlwm zoo. EVAP Leak Detection Reference Chaw nres nkoj tuaj yeem yog lub tshuab lim me me lossis tsuas yog ib feem ntawm EVAP kab uas txwv tsis pub khiav kom lub EVAP siab / ntws sensor tuaj yeem tau txais cov qauv raug.

Yog tias PCM pom qhov tsis tshua muaj dej ntws los ntawm EVAP Leak Detection Reference Chaw nres nkoj, P043E code yuav raug khaws cia thiab teeb pom kev tsis zoo (MIL) tuaj yeem teeb pom kev.

Dab tsi yog qhov hnyav ntawm DTC no?

EVAP leak detection codes zoo ib yam li P043E yog tshwj xeeb rau cov roj vapor tswj qhov system thiab yuav tsum tsis txhob muab cais raws li qhov hnyav.

Cov tsos mob ntawm txoj cai yog dab tsi?

DTC P043E cov tsos mob feem ntau yuav ua rau me me lossis tsis pom cov tsos mob. Koj tuaj yeem pom kev txo qis roj me ntsis thiab lwm yam EVAP kev kuaj pom cov lej.

Dab tsi yog qee qhov ua rau pom cov cai?

Yog vim li cas rau qhov P043E cav chaws yuav suav nrog:

• Ua tsis tau zoo EVAP siab sensor
• EVAP leak detection qhov puas los yog clogged.
• Carbon element (canister) torn
• Cracked los yog crushed EVAP los yog nqus kab / s
• Kev ua pa tsis zoo lossis tshem tawm cov tswj solenoid
• Ua tsis zoo los xyuas kom pom lub twj tso kua mis

Dab tsi yog qee cov kauj ruam los daws teeb meem P043E?

Ib lub tshuab kuaj kab mob, cov volt / ohmmeter (DVOM) thiab cov ntaub ntawv xov xwm tsheb txhim khu kev qha yuav ua pov thawj tseem ceeb rau kev kuaj xyuas P043E code.

Siv koj lub tsheb cov ntaub ntawv xov xwm los tshuaj xyuas cov ntawv xov xwm kev pabcuam (TSBs) uas phim cov tsos mob thiab cov lej qhia hauv lub tsheb raug kuaj. Yog tias koj tuaj yeem nrhiav TSB qhov tsim nyog, nws feem ntau yuav coj koj mus rau qhov tseeb ntawm qhov teeb meem yam tsis tas siv sijhawm ntau thiab siv zog.

Yog tias muaj lwm qhov system EVAP cov lej, kuaj xyuas thiab kho lawv ua ntej sim kuaj xyuas P043E. P043E tuaj yeem teb rau cov xwm txheej uas ua rau lwm tus EVAP cov lej.

Ua ntej koj tau txais koj txhais tes qias neeg, txuas lub scanner rau lub tsheb qhov chaw kuaj mob thiab khaws tag nrho cov lej khaws cia thiab khov cov ntaub ntawv. Kuv nyiam sau cov ntaub ntawv no tseg vim nws tuaj yeem pab tau thaum kuv qhov kev kuaj mob mus ntxiv. Thaum koj ua tiav qhov no, tshem cov lej thiab sim tsav lub tsheb kom paub tseeb tias cov lej raug tshem tawm.

Qhov zoo tshaj plaws, koj xav sim tsav lub tsheb kom txog thaum ib qho ntawm ob yam tshwm sim; PCM nkag mus rau hom npaj txhij los yog code cleared. Yog tias PCM nkag mus rau hauv hom kev npaj, koj muaj teeb meem ib ntus (lossis koj yuam kev kho nws) thiab tsis muaj ntau yam koj tuaj yeem ua tam sim no. Yog tias nws rov qab los tom qab, qhov kev ua tsis tiav yuav tshwm sim thiab koj tuaj yeem sim dua. Yog tias P043E rov pib dua, koj paub tias koj muaj teeb meem loj thiab nws yog lub sijhawm los khawb thiab nrhiav nws.

Pib los ntawm kev soj ntsuam pom tag nrho EVAP kab hluav taws xob thiab cov khoom sib txuas uas koj tuaj yeem nkag mus rau hauv lub sijhawm tsim nyog. Obviously, koj yuav tsis tshem tawm tej yam tseem ceeb los saib, tab sis theej tsom koj cov kev siv zog ntawm qhov kub thiab txias thiab qhov chaw uas thaiv, txuas, kab nqus tsev vacuum, thiab chav hoses tuaj yeem cuam tshuam cov khoom txav. Ntau lub tsheb tau kho thaum lub sijhawm no ntawm cov txheej txheem kuaj mob, yog li ua kom pom tseeb thiab siv zog me ntsis.

Txuas lub scanner rau lub tsheb kuaj qhov chaw nres nkoj thiab saib xyuas cov ntaub ntawv ntws. EVAP ntws thiab cov ntaub ntawv siab yuav tsum ua raws li cov chaw tsim khoom tshwj xeeb thaum lub kaw lus qhib. Feem ntau, kev ua kom lub EVAP system (purge solenoid valve thiab / los yog cov twj tso kua mis) tuaj yeem ua tiav siv lub tshuab scanner. Qee qhov kev ntsuas EVAP sensor yuav tsum tau ua nrog lub kaw lus qhib.

Siv DVOM los ntsuas EVAP sensors thiab solenoids los sib piv rau cov chaw tsim khoom tshwj xeeb. Txhua yam khoom siv uas tsis muaj qhov tshwj xeeb yuav tsum tau hloov. Yog tias ua tau, nkag mus rau EVAP qhov chaw kuaj xyuas kom pom cov hluav taws xob. Yog tias pom muaj pa paug paug, xav tias EVAP canister tau raug cuam tshuam.

Ua ntej ntsuas qhov system circuits nrog DVOM, txiav tawm tag nrho cov tswj kev cuam tshuam los tiv thaiv kev puas tsuaj. Txheeb xyuas qhov kev tiv thaiv tsim nyog thiab qib txuas ntxiv ntawm tus kheej EVAP cov khoom thiab PCM siv DVOM. Chains uas tsis ua raws li cov lus qhia tshwj xeeb yuav tsum tau kho lossis hloov.

• Lub hau roj xoob lossis tsis zoo yuav tsis khaws P043E code.
• Txoj cai no tsuas yog siv rau lub tsheb EVAP uas siv lub tshuab nqus dej kom pom.

Lwm yam kev sib tham DTC

• 05 Corolla P2419, P2402, P2401, P043F, P043ENyob zoo sawv daws Qhov no yog kuv thawj zaug ntawm lub rooj sab laj. Yog li nws zoo li kuv muaj teeb meem nrog kuv Corolla. Nws tau tsav dhau 300,000 km thiab zoo li ua haujlwm zoo. Lub cav teeb tuaj txog, Kuv tau kuaj xyuas cov lej thiab tau txais cov lej hauv qab no: P2419, P2402, P2401, P043F, P043E Txhua yam txuas nrog lub evaporator ...
