P0441 Evaporative emission tswj system tshem tawm cov dej tsis raug

P0441 – OBD-II Teeb meem Code Technical Description

Evaporative emissions tswj system. Kev lim dej tsis raug.

Qhov txhaum cai txhais li cas P0441?

DTC P0441 yog ib tug generic code rau evaporative emission tswj (EVAP) system thiab siv rau OBD-II nruab tsheb. Nws qhia tau hais tias muaj teeb meem nrog EVAP system, uas tiv thaiv cov roj vapor mus rau hauv qhov chaw.

EVAP system muaj ntau yam khoom, suav nrog lub hau roj, roj kab, charcoal canister, ntxuav valve, thiab hoses. Nws tiv thaiv cov roj vapors los ntawm kev khiav tawm ntawm cov roj hluav taws xob los ntawm kev coj lawv mus rau hauv lub charcoal canister cia. Tom qab ntawd, thaum lub cav ua haujlwm, lub tshuab nqus tsev tswj lub valve qhib, tso cai rau lub tshuab nqus tsev los ntawm lub cav kom tso cov roj vapor mus rau hauv lub cav rau combustion es tsis tso rau hauv qhov chaw.

Tus lej P0441 tau tshwm sim thaum ECU pom qhov txawv txav ntawm cov dej ntws hauv EVAP, uas tuaj yeem tshwm sim los ntawm ntau qhov laj thawj suav nrog cov khoom tsis xws luag lossis kev ua haujlwm. Cov cai no feem ntau yog nrog rau lub teeb Check Engine ntawm lub dashboard.

Kev daws qhov teeb meem no yuav xav tau kev kuaj mob thiab hloov lossis kho EVAP cov khoom siv xws li kev tswj xyuas lub valve, lub tshuab nqus tsev hloov, lossis lwm yam khoom.

Tej zaum ua rau

Code P0441 tuaj yeem tshwm sim los ntawm cov laj thawj hauv qab no:

1. Faulty lub tshuab nqus tsev hloov.
2. Cov kab puas lossis tawg lossis EVAP canister.
3. Qhib hauv PCM clear command circuit.
4. luv luv Circuit Court los yog qhib Circuit Court nyob rau hauv Circuit Court muab voltage rau lub solenoid ntxuav.
5. Solenoid tshem tawm tsis zoo.
6. Kev txwv hauv kev ua haujlwm ntawm solenoid, kab lossis canister ntawm EVAP system.
7. Corrosion los yog tsis kam nyob rau hauv lub solenoid connector.
8. Faulty gas cap.

Txoj cai no qhia txog cov teeb meem nrog evaporative emission control (EVAP) system thiab yuav tsum muaj kev kuaj mob los txiav txim seb qhov ua rau qhov yuam kev.

Cov tsos mob ntawm tus lej yuam kev yog dab tsi? P0441?

Feem ntau, cov neeg tsav tsheb yuav tsis muaj cov tsos mob cuam tshuam nrog P0441 code uas tsis yog kev ua kom lub teeb pom kev ntawm lub teeb pom kev ntawm lub dashboard. Tsis tshua muaj, cov roj tsw qab yuav tshwm sim, tab sis qhov no tsis yog qhov tshwm sim ntawm qhov teeb meem.

Yuav ua li cas kuaj tau tus lej txhaum P0441?

Tus kws tshaj lij yuav pib los ntawm kev txuas lub cuab yeej scan rau ECU txhawm rau txheeb xyuas cov lej yuam kev. Nws mam li luam cov ntaub ntawv tseem duab uas qhia tias thaum twg cov cai tau teeb tsa.

Tom qab ntawd, cov cai yuav raug tshem tawm thiab kev sim tsav yuav raug ua.

Yog tias tus lej rov qab los, kev tshuaj xyuas pom ntawm EVAP system yuav raug ua.

Siv lub scanner, cov ntaub ntawv tam sim no ntawm cov roj siab hauv lub tank yuav raug kuaj xyuas qhov tsis raug.

Lub hau roj yuav raug tshuaj xyuas thiab kuaj.

Tom ntej no, lub tshuab kuaj kab mob yuav raug siv los xyuas kom meej tias lub tshuab nqus tsev vacuum thiab ntxuav lub valve ua haujlwm raug.

Yog tias tsis muaj ib qho ntawm cov kev ntsuam xyuas saum toj no muab cov lus teb meej, yuav tsum kuaj cov pa luam yeeb kom pom cov xau hauv EVAP.

Thaum kuaj pom P0441 OBD-II teeb meem code, cov kauj ruam hauv qab no yuav tsum tau:

1. Hloov lub twj tso kua mis kom pom (LDP) yog ib qho kev kho rau Chrysler.
2. Kho cov kab EVAP puas los yog cov kab canister.
3. Kho qhov qhib lossis luv Circuit Court nyob rau hauv qhov hluav taws xob muab hluav taws xob mus rau qhov ntxuav solenoid.
4. Kho qhov qhib Circuit Court hauv PCM clear command circuit.
5. Hloov lub purge solenoid.
6. Hloov lub tshuab nqus tsev hloov.
7. Txwv kev kho rau kab evaporator, canister lossis solenoid.
8. Tshem tawm tsis kam nyob rau hauv lub solenoid connector.
9. Hloov lub PCM (electronic engine control module) yog tias tag nrho lwm yam tsis daws teeb meem.

Nws tseem tsim nyog saib rau lwm cov EVAP yuam kev lis dej num xws li P0440, P0442, P0443, P0444, P0445, P0446, P0447, P0448, P0449, P0452, P0453, P0455 thiab P0456.

Kev kuaj mob yuam kev

Feem ntau, kev ua yuam kev tshwm sim vim tsis muaj cov khoom tseem ceeb lossis cov kauj ruam kuaj mob. Qee zaum nws yuav tsum tau kuaj xyuas cov pa luam yeeb. Rau kev ntseeg tau ntawm qhov kev sim no, cov roj qib hauv lub tank yuav tsum nyob rau hauv thaj tsam ntawm 15% txog 85%.

Txawm hais tias lub hau roj yog qhov ua rau ntau tshaj plaws ntawm P0441 code, nws yuav tsum tau ua tib zoo tshuaj xyuas thiab kuaj. Lub hau roj tuaj yeem raug kuaj xyuas siv lub tshuab nqus tsev nqus los yog siv lub tshuab nqus tsev vacuum, uas tuaj yeem nthuav tawm cov pa tawm ntawm lub hau roj.

Txoj cai txhaum loj npaum li cas? P0441?

Code P0441 feem ntau tsis yog qhov hnyav thiab feem ntau tsuas yog cov tsos mob tshwm sim yog lub teeb pom kev ntawm lub cav. Txawm li cas los xij, nws yuav tsum tau muab sau tseg tias nyob rau hauv ntau lub xeev, lub tsheb nrog lub teeb pom kev ntawm lub cav yuav tsis dhau OBD-II emissions tests, yog li nws pom zoo kom kho qhov txhaum tam sim ntawd. Cov roj tsw qab me ntsis uas qee zaum nrog EVAP teeb meem hauv lub cev tuaj yeem ua rau muaj kev txhawj xeeb rau qee tus tswv.

Kev kho dab tsi yuav pab tshem tawm cov cai? P0441?

• Hloov cov roj tank cap.
• Txhim kho qhov xau hauv EVAP system.
• Kho cov khoom puas EVAP uas tau raug txheeb xyuas tias muaj teeb meem.
• Hloov cov pa tawm valve.
• Hloov lub tshuab nqus tsev vacuum faulty.
• Kho lossis hloov cov hlau puas.
