P043F Evap Leak Detection Reference Orifice Siab

OBD-II DTC Cov Ntaub Ntawv

Evaporative Emission System Leak Detection Reference Orifice High Flow

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 evaporative emissions system (EVAP) xau nrhiav pom qhov chaw thaum tus lej P043F khaws cia hauv koj lub tsheb OBD-II. Nyob rau hauv cov ntaub ntawv no, ib tug high 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 kuaj pom qhov muaj dej ntws siab dhau los ntawm EVAP cov ntaub ntawv pov thawj pom, tus lej P043F yuav raug khaws cia thiab lub teeb pom kev tsis zoo (MIL) yuav raug teeb pom kev zoo.

Dab tsi yog qhov hnyav ntawm DTC no?

EVAP cov lej kuaj pom, zoo ib yam li P043F, cuam tshuam tshwj xeeb nrog cov evaporative emission tswj system thiab yuav tsum tsis txhob raug cais raws li qhov hnyav.

Cov tsos mob ntawm txoj cai yog dab tsi?

Cov tsos mob ntawm P043F DTC tuaj yeem suav nrog:

Tsis muaj cov tsos mob yuav tshwm sim
Suab nrov lossis humming suab (txawm tias thaum lub teeb hluav taws xob kaw)
Txo txo kev siv roj me ntsis
Lwm cov EVAP cov lej kuaj xyuas cov dej xau tuaj yeem khaws cia

Dab tsi yog qee qhov ua rau pom cov cai?

Yog vim li cas rau qhov P043F cav code yuav suav nrog:

Ua tsis tau zoo EVAP siab sensor
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 P043F cov teeb meem daws teeb meem?

Lub tshuab kuaj kab mob, lub tshuab hluav taws xob digital volt / ohmmeter (DVOM), thiab cov ntaub ntawv xov xwm tsheb txhim khu kev qha yuav ua pov thawj tsim nyog rau kev kuaj xyuas tus lej P043F.

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 cov EVAP cov cai tam sim no, kuaj xyuas thiab kho cov no ua ntej sim kuaj xyuas P043F. P043F tuaj yeem cuam tshuam rau cov xwm txheej uas tau ua rau lwm cov lej EVAP.

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 kev npaj los yog qhov chaws rov pib dua. Yog tias PCM nkag mus rau hom kev npaj, koj muaj qhov teeb meem tsis sib xws (lossis koj tau kho nws tsis ua haujlwm) thiab tsis muaj ntau yam uas koj tuaj yeem ua tam sim no. Yog tias nws rov qab los tom qab, qhov xwm txheej tsis ua haujlwm yuav zoo dua thiab koj tuaj yeem ua lwm yam ntawm nws. Yog tias P043F rov pib dua, koj paub tias koj muaj qhov ua haujlwm nyuaj thiab nrawm 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 txhawm rau muab piv nrog cov chaw tsim khoom tshwj xeeb. Txhua yam khoom uas tsis sib xws nrog cov kev qhia tshwj xeeb yuav tsum tau hloov. Yog tias ua tau, nkag mus rau EVAP cov ntaub ntawv pov thawj cov ntaub ntawv pov thawj los kuaj xyuas cov pa hluav taws xob. Yog tias pom muaj cov 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 hmab xoob lossis tsis ua tiav yuav tsis ua rau tus lej P043F khaws cia
Txoj cai no tsuas yog siv rau lub tsheb EVAP uas siv lub tshuab nqus dej kom pom.
