P0405 Qhov ntsuas qis Circuit Court ntawm lub ntsuas A ntawm cov pa tso pa rov ua haujlwm

OBD-II Teeb meem Code - P0405 ​​​​- Kev piav qhia

Tsawg teeb liab theem nyob rau hauv lub tso pa roj recirculation sensor Circuit Court.

P0405 yog ib qho generic OBD-II code qhia tias lub Cav Tswj Module (ECM) tau kuaj pom tias Lub Cav Hluav Taws Xob Hluav Taws Xob Recirculation (EGR) sensor tawm ntawm qhov ntau. Luv rau hauv av sensor input rau ECM.

Qhov teeb meem code P0405 txhais li cas?

Qhov Diagnostic Trouble Code (DTC) no yog tus lej siv dav, uas txhais tau tias nws siv rau OBD-II cov tsheb uas muaj cuab yeej siv. Txawm hais tias qhov dav dav, cov txheej txheem kho tshwj xeeb yuav txawv nyob ntawm cov khoom lag luam / qauv.

Muaj cov qauv sib txawv ntawm cov pa roj recirculation systems, tab sis lawv txhua tus ua haujlwm tib yam. Lub Nqus Pa Roj Recirculation Valve yog lub valve tswj los ntawm PCM (Powertrain Control Module) uas tso cai rau ntsuas cov pa hluav taws xob kom rov qab mus rau hauv lub tog raj kheej rau kev sib txuas nrog rau huab cua / roj sib xyaw. Vim tias cov pa hluav taws xob tso tawm yog cov roj tsis muaj zog uas hloov cov pa oxygen, kev txhaj tshuaj rov qab rau hauv lub tog raj kheej tuaj yeem txo qhov kub ntawm qhov hluav taws xob, uas yuav pab txo qis NOx (nitrogen oxide) emissions.

EGR tsis xav tau thaum lub caij txias lossis tsis ua haujlwm. EGR muaj zog nyob rau qee qhov xwm txheej, xws li pib lossis tsis ua haujlwm. EGR system tau muab rau hauv qee qhov xwm txheej, xws li ib nrab ntawm qhov ua kom qeeb lossis qeeb, nyob ntawm seb lub cav kub thiab thauj khoom, thiab lwm yam. Cov pa roj tau muab tso rau EGR valve los ntawm cov pa tso tawm, lossis EGR valve tuaj yeem teeb tsa ncaj qha rau hauv qhov tso pa tawm. . Yog tias tsim nyog, lub valve tau qhib, tso cov roj nkag mus rau hauv lub tog raj kheej. Qee lub tshuab ncaj qha tso cov pa ncaj qha mus rau hauv lub tog raj kheej, thaum lwm tus tsuas yog txhaj lawv rau hauv qhov tso pa tawm, los ntawm qhov chaw uas lawv tau rub mus rau hauv lub tog raj kheej. thaum lwm tus neeg yooj yim txhaj nws rau hauv qhov nqus dej, los ntawm qhov uas nws tau rub mus rau hauv lub tog raj kheej.

Qee lub tshuab EGR yog qhov yooj yim haum, thaum lwm tus yog qhov nyuaj me ntsis. Kev tswj hluav taws xob tso pa roj rov ua haujlwm qub yog tswj lub computer ncaj qha. Cov hlua khi txuas rau lub valve nws tus kheej thiab raug tswj los ntawm PCM thaum nws pom qhov xav tau. Nws tuaj yeem yog 4 lossis 5 xov hlau. Feem ntau 1 lossis 2 thaj chaw, 12V qhov hluav taws xob hluav taws xob Circuit Court, 5V siv Circuit Court, thiab cov lus tawm tswv yim. Lwm lub tshuab yog tswj lub tshuab nqus tsev. Nws zoo nkauj ncaj. PCM tswj lub tshuab nqus tsev solenoid uas, thaum ua haujlwm, tso cai rau lub tshuab nqus tsev mus rau thiab qhib EGR valve. Hom EGR valve no yuav tsum muaj kev sib txuas hluav taws xob rau kev tawm tswv yim Circuit Court. EGR cov lus tawm tswv yim tso cai rau PCM los saib yog tias EGR valve tus pin tau txav mus los tiag. Yog tias qhov kev tawm tswv yim ntsuas pom tias qhov hluav taws xob qis qis lossis qis dua qhov ntsuas qhov tshwj xeeb, P0405 tuaj yeem teeb tsa.

Cov tsos mob

Cov tsos mob ntawm P0405 teeb meem chaws yuav suav nrog:

• MIL Illumination (Qhov Taw Qhia Tsis Ua Haujlwm)
• Lub teeb Check Engine yuav los thiab cov cai yuav muab khaws cia rau hauv ECM.
• ECM tuaj yeem qhib EGR valve ntau tshaj qhov tsim nyog yog tias qhov hluav taws xob qis dhau, ua rau lub cav nres lossis wobble thaum nrawm.
• Lub cav EGR system tuaj yeem ua rau lub cav khiav tsis zoo, oscillate, lossis txawm tias nws tsis qhia qhov tseeb ntawm EGR valve ntawm ECM.
• Lub ECM tuaj yeem thaiv lub valve los ntawm kev qhib thaum nws pom qhov ua haujlwm tsis zoo, thiab lub cav tuaj yeem ua ntej ignite ntawm acceleration.

Ua rau P0405 code

Ua tau ntawm P0405 cov cai suav nrog:

• Luv mus rau hauv av hauv EGR cov teeb liab hluav taws xob lossis cov ntawv siv hluav taws xob
• Cov hluav taws xob luv luv rau qhov hluav taws xob hauv av hauv av lossis cov hluav taws xob hluav taws xob ntawm cov pa tso pa tawm
• Tsis zoo EGR valve
• Teeb meem PCM cov xov hluav taws xob tsis zoo vim qhov tawg lossis plam qhov kawg

Cov kev daws teeb meem

Yog tias koj muaj kev nkag mus rau lub cuab yeej scan, koj tuaj yeem hais kom EGR valve ON. Yog tias nws tau teb thiab tawm tswv yim qhia tias lub valve txav mus tau zoo, qhov teeb meem tuaj yeem sib quas ntus. Qee zaum, thaum huab cua txias, cov dej noo tuaj yeem khov hauv lub valve, ua rau nws lo. Tom qab ua kom sov lub tsheb, qhov teeb meem yuav ploj mus. Cov pa roj carbon lossis lwm yam khib nyiab tuaj yeem daig hauv lub qhov dej ua rau nws lo.

Yog tias cov pa tso pa tawm rov qab tsis teb rau cov cuab yeej ntsuas ntsuas, tshem tawm cov pa tso pa rov ua kom sib txuas. Tig tus yuam sij rau txoj haujlwm "ntawm", lub cav tawm (KOEO). Siv lub ntsuas hluav taws xob los ntsuas 5 V ntawm qhov ntsuas ntawm EGR valve. Yog tias tsis muaj 5 volts, puas muaj qhov hluav taws xob txhua? Yog tias qhov hluav taws xob yog 12 volts, kho qhov luv luv rau qhov hluav taws xob ntawm 5 volt siv hluav taws xob. Yog tias tsis muaj qhov hluav taws xob tam sim no, txuas lub teeb ntsuas rau lub roj teeb hluav taws xob thiab tshawb xyuas 5 V siv hlau. Kho yog tsim nyog. Yog tias lub teeb ntsuas tsis pom kev, ntsuas qhov ntsuas 5 V rau qhov qhib. Kho yog tsim nyog.

Yog tias tsis muaj teeb meem tshwm sim thiab tsis muaj qhov siv 5 volt, PCM tej zaum yuav muaj qhov tsis xws, txawm li cas los xij lwm cov lej muaj feem yuav tshwm sim. Yog tias muaj 5 volt nyob rau hauv kab lus siv, txuas 5 volt jumper hlau mus rau EGR teeb liab Circuit Court. Cov cuab yeej ntsuas EGR txoj haujlwm yuav tsum tam sim no nyeem 100 feem pua. Yog tias nws tsis txuas lub teeb ntsuas mus rau lub roj teeb hluav taws xob, xyuas lub teeb liab Circuit Court kom pom cov pa tso pa tawm. Yog tias nws nyob, ces lub teeb liab Circuit Court luv rau hauv av. Kho yog tsim nyog. Yog tias qhov ntsuas tsis pom kev, kos rau qhib rau hauv EGR teeb liab Circuit Court. Kho yog tsim nyog.

Yog tias, tom qab txuas 5 V siv lub voj voos mus rau EGR lub teeb liab hluav taws xob, lub cuab yeej luam theej tawm qhia txog EGR txoj haujlwm ntawm 100 feem pua, tshuaj xyuas qhov tsis zoo ntawm qhov chaw nyob ntawm EGR qhov txuas txuas. Yog tias qhov thaiv tau zoo, hloov EGR valve.

Cov lej EGR cuam tshuam: P0400, P0401, P0402, P0403, P0404, P0406, P0407, P0408, P0409

YUAV UA LI CAS MECHANIC DIAGNOSIS A P0405 CODE?

• Tshawb xyuas cov lis dej num thiab cov ntaub ntawv khov cov ntaub ntawv kom paub meej tias qhov teeb meem
• Clear engine codes thiab txoj kev kuaj xyuas seb puas ntshai thiab cov lej rov qab los.
• Saib xyuas lub pid ntawm EGR sensor ntawm lub scanner kom pom tias lub sensor qhia tias lub valve yog nyob rau hauv qhov raug kaw txoj hauj lwm los yog lub sensor voltage tawm tswv yim hauv qab specification.
• Tshem tawm EGR sensor connector, tshuaj xyuas lub connector rau corrosion thiab ntxuav yog tsim nyog.
• Kos lub connector yog hais tias 5 volt siv mus txog lub sensor connector.
• Txuas lub ntsuas hluav taws xob siv hluav taws xob thiab cov lus tawm tswv yim ua ke thiab tshawb xyuas lub tshuab luam ntawv kom pom qhov siv hluav taws xob ntawm EGR sensor pid sensor.
• Hloov lub EGR sensor lossis kho cov xaim raws li xav tau, tom qab ntawd muab ob npaug rau kev nyeem ntawv kom raug.

COMMON yuam kev thaum kuaj xyuas tus lej P0405

• Tsis txhob txuas lub ntsuas hluav taws xob siv hluav taws xob thiab cov lus qhia tawm tswv yim ua ke kom paub tseeb tias txhua txoj hlua hluav taws xob zoo ua ntej hloov EGR txoj hauj lwm sensor.
• Tsis tuaj yeem kuaj xyuas cov xaim thiab txuas rau EGR txoj hauj lwm sensor rau luv luv Circuit Court lossis qhib Circuit Court ua ntej hloov EGR txoj hauj lwm sensor.

YUAV TSUM TAU TXAIS P0405 YOG?

• ECM tuaj yeem lov tes taw EGR system thiab ua rau nws ua haujlwm tsis tau thaum tus lej no ua haujlwm.
• Illumination ntawm Check Engine lub teeb yuav ua rau lub emission test tsis ua hauj lwm.
• Txoj hauj lwm ntawm EGR yog qhov tseem ceeb rau ECM kom tswj tau qhov qhib thiab kaw ntawm EGR valve thiab tuaj yeem ua rau lub cav khiav tsis zoo thiab nres.

Kev kho dab tsi tuaj yeem kho tus lej P0405?

• Hloov EGR txoj hauj lwm sensor, xyuas kom cov xaim zoo.
• Short Harness Attachment to EGR Position Sensor lossis Signal Return Connector
• Tshem tawm ntawm kev tawg hauv qhov siv hluav taws xob rau EGR sensor

YUAV TSUM TAU TXAIS NTAWM CODE P0405

Code P0405 yog tshwm sim thaum EGR txoj hauj lwm qis dua qhov xav tau ECM sensor txoj hauj lwm thiab feem ntau yog vim li cas EGR sensor muaj qhov qhib sab hauv.
