P0445 luv Circuit Court nyob rau hauv lub purge valve Circuit Court ntawm cov roj vapor tswj system

P0445 – OBD-II Teeb meem Code Technical Description

Teeb meem code P0445 qhia tias muaj teeb meem nrog lub evaporative tswj system ntxuav solenoid valve.

Qhov txhaum cai txhais li cas P0445?

Teeb meem code P0445 qhia tias muaj teeb meem nrog kev tshem tawm solenoid valve hauv evaporative tswj system. Txoj cai no txhais tau hais tias lub solenoid valve, uas tswj cov ntws ntawm cov roj vapor mus rau hauv lub cav rau combustion, tsis ua haujlwm zoo.

Tej zaum ua rau

Muaj ob peb yam ua tau rau P0445 teeb meem code:

• Faulty ntxuav solenoid valve: Feem ntau thiab tej zaum qhov teeb meem ntawm qhov teeb meem yog faulty purge solenoid valve uas tsis qhib los yog kaw kom zoo.
• Cov xaim puas lossis cov khoom sib txuas: Cov xov hlau txuas nrog lub tshuab ntxuav solenoid valve yuav raug puas tsuaj, tawg, lossis muaj kev sib txuas tsis zoo. Tsis tas li ntawd, cov connectors yuav oxidized los yog qias neeg.
• Valve txoj hauj lwm sensor malfunction: Yog hais tias lub evaporative emission tswj system muaj lub valve txoj hauj lwm sensor, ib tug malfunction ntawm no sensor kuj yuav ua rau lub P0445 code tshwm.
• Teeb meem nrog evaporative emission system: Ntxiv rau qhov kev tshem tawm ntawm nws tus kheej, cov dej ntws los yog kev puas tsuaj rau lwm yam evaporative emission system tuaj yeem ua rau P0445 code.
• Engine Control Module (ECM) malfunction: Nyob rau hauv tsawg zaus, qhov teeb meem yuav yog vim lub cav tsis ua hauj lwm tswj module uas tsis muaj peev xwm khiav lub valve kom raug.

Cov laj thawj uas ua tau no yuav tsum raug suav hais tias yog qhov pib thaum kuaj pom P0445 teeb meem code, tab sis kev soj ntsuam ntxaws ntxiv thiab kev kuaj mob yuav tsum tau txheeb xyuas qhov teeb meem.

Cov tsos mob ntawm tus lej yuam kev yog dab tsi? P0445?

Cov tsos mob rau DTC P0445 yuav suav nrog cov hauv qab no:

• Lub teeb "Check Engine" los rau: Lub cim tseem ceeb ntawm qhov teeb meem yuav yog lub teeb "Check Engine" ntawm lub tsheb dashboard tuaj. Qhov no feem ntau yog thawj lub cim qhia tias ib yam dab tsi tsis ncaj ncees lawm nrog evaporative emission tswj system.
• Lub cav tsis zoo lossis tsis ruaj khov: Lub faulty purge valve yuav ua rau lub cav khiav ntxhib, co los yog idling ntxhib.
• Kev ua haujlwm tsis zoo: Kev ua haujlwm tsis zoo hauv cov evaporative emission tswj qhov system kuj tuaj yeem ua rau lub cav ua haujlwm tsis zoo lossis cov lus teb tsis zoo.
• Roj tsw qab: Yog tias cov roj vapor rov qab los, tej zaum yuav muaj roj tsw qab nyob ib ncig ntawm lub tsheb, tshwj xeeb tshaj yog nyob rau thaj tsam ntawm lub tank.
• Poob roj: Yog hais tias lub purg valve los yog lwm yam khoom ntawm lub evaporative emission system malfunction, roj poob yuav tshwm sim, uas ua rau kom muaj roj noj thiab txo lub tank cia.

Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov tsos mob yuav txawv nyob ntawm seb qhov ua rau P0445 teeb meem code thiab lub tsheb qauv. Yog tias koj pom ib qho ntawm cov tsos mob saum toj no, nws raug nquahu kom koj hu rau tus kws tshaj lij txhawm rau kuaj xyuas thiab kho.

Yuav ua li cas kuaj tau tus lej txhaum P0445?

Txhawm rau kuaj xyuas DTC P0445, ua raws li cov kauj ruam no:
