P0446 Evaporative emission tswj qhov cua tswj Circuit Court

P0446 – OBD-II Teeb meem Code Technical Description

evaporative emission tswj qhov cua tswj Circuit Court malfunction

Qhov txhaum cai txhais li cas P0446?

Teeb meem code P0446 muaj feem xyuam rau evaporative emissions control system (EVAP) thiab feem ntau qhia txog teeb meem nrog lub qhov cua valve. Lub valve no yog lub luag haujlwm rau kev tswj lub siab thiab tiv thaiv roj vapor los ntawm qhov system. Yog tias nws tsis ua haujlwm zoo, nws tuaj yeem ua rau ntau yam yuam kev xws li P0442 txog P0463. Kev kho muaj xws li hloov lossis kho lub qhov cua valve, xyuas cov tswj Circuit Court, thiab lwm yam kev ntsuas ntsuas.

Tej zaum ua rau

Teeb meem code P0446 yuav qhia txog cov teeb meem hauv qab no:

1. Faulty vent valve.
2. Teeb meem nrog lub qhov hluav taws xob valve tswj Circuit Court, xws li qhib, luv luv, los yog kev tiv thaiv ntau dhau.
3. Qhov cua valve clogged.
4. Tej zaum yuav muaj teeb meem nrog PCM (engine control software module).

Feem ntau ua rau ntawm qhov kev ua yuam kev no yog qhov ua yuam kev lossis txhaws qhov valve, tswj cov teeb meem hauv Circuit Court xws li faulty wiring. Kuj yuav tsum paub tias tej zaum yuav muaj lwm yam xws li lub hau roj uas ploj lawm, siv lub hau roj tsis raug, lossis muaj kev cuam tshuam hauv lub hau roj.

Cov tsos mob ntawm tus lej yuam kev yog dab tsi? P0446?

P0446 yuam kev cai feem ntau tshwm sim nws tus kheej nrog cov tsos mob hauv qab no:

1. Lub teeb kos lub cav (MIL) lossis teeb tsis ua haujlwm ntawm lub ntsuas ntsuas vaj huam sib luag tuaj.
2. Muaj peev xwm ceeb toom ntawm tsis hnov ​​tsw ntawm roj, tshwj xeeb tshaj yog thaum sawv ntawm lub tsheb.

Cov cai no qhia txog teeb meem nrog evaporative emissions control (EVAP) pa valve. Txawm li cas los xij, nws tseem tsim nyog sau cia tias lwm yam teeb meem ntawm lub tsheb tuaj yeem ua rau cov cai no tshwm sim, xws li lub tshuab hluav taws xob tsis zoo, qhov txhaws lossis cov kav dej puas lossis cov lim dej tsis zoo, lossis qhov ua txhaum ntawm EVAP system siab sensor. Qhov no kuj tseem tuaj yeem ua rau lwm yam EVAP qhov cuam tshuam txog cov lej yuam kev.

Yuav ua li cas kuaj tau tus lej txhaum P0446?

Nws raug nquahu kom koj hu rau tus kws tshaj lij los kuaj xyuas thiab daws qhov P0446 code. Lawv yuav tsum ua kom tiav cov kauj ruam hauv qab no:

2. Txheeb xyuas qhov xwm txheej ntawm lub hau roj, hloov nws yog tias tsim nyog.
3. Ntsuam xyuas EVAP system rau cov pa xau siv lub tshuab hluav taws xob pa luam yeeb.
4. Txheeb xyuas qhov xwm txheej ntawm EVAP qhov cua tswj valve, ntxuav nws lossis hloov nws yog tias tsim nyog.
5. Xyuas kom tseeb tias muaj hwj chim thiab hauv av nyob rau hauv lub tswj Circuit Court.
6. Sim nruj lub hau roj thiab tshem tawm qhov yuam kev yog tias nws puas lawm.
7. Yog tias tus lej P0446 txuas ntxiv mus tom qab cov kauj ruam saum toj no, yuav tsum muaj kev kuaj mob ntau dua.

Nws tseem tsim nyog sau cia tias P0446 code tuaj yeem tshwm sim vim muaj lwm yam teeb meem nrog EVAP system, yog li nws yog ib qho tseem ceeb uas yuav tsum tau ua txhua yam kev kuaj mob tsim nyog kom paub meej lub hauv paus ntawm qhov teeb meem.

Kev kuaj mob yuam kev

Ntu ntu ntawm tsab xov xwm "Yuam kev thaum kuaj pom P0446":

Ua yuam kev tsis quav ntsej lwm yam DTCs: Qee zaum cov kws kho tsheb tsuas yog tsom rau P0446 code thaum saib lwm cov lej cuam tshuam xws li P0442 lossis P0455 uas yuav qhia txog teeb meem cuam tshuam hauv EVAP system. Qhov no tuaj yeem ua rau tsis raug kuaj xyuas thiab kev daws teeb meem ntawm lub hauv paus ua rau P0446 code. Yog li ntawd, nws yog ib qho tseem ceeb kom ua tib zoo txheeb xyuas tag nrho cov lej yuam kev thiab ua qhov kev kuaj mob dav dav ntawm EVAP system kom raug txheeb xyuas qhov tsis raug.

Txoj cai txhaum loj npaum li cas? P0446?

Qhov hnyav ntawm P0446 code, txawm tias me, tsis txhais hais tias nws yuav tsum tsis quav ntsej. Teeb meem nrog koj lub tsheb EVAP system tuaj yeem ua rau lwm yam khoom tseem ceeb ntawm lub tsheb thiab ua rau cov lej yuam kev ntxiv tshwm sim.

P0446 Piav Qhia - EVAP Emission Control System Qhov Cuam Tshuam Tswj Circuit Court Malfunction (Kev Kho Yooj Yim)

P0446 - Cov ntaub ntawv tshwj xeeb ntawm hom

DESCRIPTION FORD P0446

Lub canister vent solenoid valve, ib feem ntawm evaporative emissions control (EVAP) system, yog nyob rau ntawm EVAP canister thiab ua haujlwm tseem ceeb hauv kev sib khi lub kaus poom. Cov khoom no teb rau cov teeb liab los ntawm Cav Tswj Module (ECM). Thaum ECM xa cov lus txib ON, lub valve tau qhib, txav lub piston thiab kaw lub qhov cua hauv lub kaus poom. Lub foob no yog tsim nyog los kuaj xyuas lwm yam khoom ntawm evaporative emission tswj system. Nws yog ib qho tseem ceeb kom nco ntsoov tias qhov solenoid valve feem ntau tseem qhib tshwj tsis yog thaum lub sijhawm kuaj mob.
