OBD-II DTC Cov Ntaub Ntawv

EGR Vent Control Circuit Siab

Qhov no txhais li cas?

Qhov no yog lub zog ntsuas hluav taws xob kuaj pom teeb meem (DTC) thiab feem ntau siv rau tsheb OBD-II. Cov npe tsheb tuaj yeem suav nrog, tab sis tsis txwv rau, Citroen, Peugeot, Sprinter, Pontiac, Mazda, Chevy, GMC, Ford, Dodge, Ram, thiab lwm yam.

EGR (Kev Siv Hluav Taws Xob Kev Siv Hluav Taws Xob) tau saib xyuas tas li thiab tswj hwm los ntawm ECM (Kev Tswj Lub Tshuab Qauv) thaum peb tsav peb lub tsheb. Cov pa roj rov ua dua tshiab (EGR) cov tshuab tso cai rau koj lub tsheb lub cav kom rov siv roj / cua sib tov uas tau dhau los ntawm cov txheej txheem tua hluav taws tab sis tseem tsis tau hlawv tawm tag nrho thiab muaj txiaj ntsig. Los ntawm kev rov ua dua qhov sib xyaw ua ke ib nrab hlawv thiab rov pub nws rau lub cav, EGR ib leeg ua rau kom muaj kev lag luam roj ntau ntxiv, tsis hais txog kev txhim kho kev tso tsheb tag nrho.

Feem ntau EGR li qub niaj hnub no yog tswj hluav taws xob los ntawm hluav taws xob solenoids, kho tshuab los ntawm lub tshuab nqus tsev tswj solenoids, thiab ntau yam lwm txoj hauv kev ua tau raws li koj tsim thiab qauv. Cov pa tso pa tawm rov ua pa solenoid feem ntau yog siv los tshem cov pa nkev uas tsis tsim nyog yuav tsum tau rov ua dua tshiab. Lawv feem ntau pov tseg qhov tso pa tsis huv no rov qab mus rau qhov tso pa tawm tom qab dhau los ntawm cov hloov pauv catalytic, resonators, mufflers, thiab lwm yam. los ntawm kev tso tsheb tawm sai. EGR lub qhov hluav taws xob tswj qhov hluav taws xob tuaj yeem xa mus rau ib qho xaim tshwj xeeb uas ua rau lub cev tsis ua haujlwm, nco ntsoov xa mus rau koj phau ntawv qhia kev pabcuam txhawm rau txiav txim siab qhov tseeb ntawm lub cev uas koj tab tom ua haujlwm ntawm no.

Los ntawm kev saib xyuas thiab kho ntau qhov ntsuas, hloov pauv, tsis hais txog lwm lub tshuab, ECM (Lub Cav Tswj Tus Qauv) tau qhib P2145 thiab / lossis cov lej cuam tshuam (P2143 thiab P2144) kom qhia rau koj paub tias muaj teeb meem nrog EGR qhov cua tswj. lub tswv yim

Nyob rau hauv rooj plaub ntawm P2145, qhov no txhais tau tias muaj qhov hluav taws xob siab tau pom hauv EGR lub qhov rooj tswj qhov cua.

Dab tsi yog qhov hnyav ntawm DTC no?

Hais txog qhov hnyav, kuv yuav hais tias qhov no yog qhov ua yuam kev me ntsis, thiab kuv yuav qhia koj vim li cas. Cov pa roj rov ua dua tshiab (EGR) system yog xaiv tau rau lub cav ua haujlwm. Txawm li cas los xij, nws txo qis thiab tseem pab koj lub cav kom ua haujlwm tau zoo nyob rau ntau yam xwm txheej, yog li nws qhov kev ua tau zoo yog qhov tseem ceeb yog tias koj xav kom koj lub tsheb ua haujlwm thiab ua haujlwm tau zoo. Tsis txhob hais txog, yog tias nyob rau qhov ntev txaus, soot dhau los ntawm cov kab ke no tuaj yeem txhim kho thiab ua rau muaj teeb meem / teeb meem yav tom ntej. Tswj EGR system kom zoo kom tsis txhob mob taub hau.

Cov tsos mob ntawm txoj cai yog dab tsi?

Cov tsos mob ntawm P2145 tus lej kuaj mob tuaj yeem suav nrog:

• Txo lub cav fais fab
• Rough engine idling
• Kev nrawm nrawm
• Kev lag luam roj tsis zoo
• CEL (kos lub cav teeb) rau
• Cov tsos mob zoo ib yam li lub cav tsis raug

Dab tsi yog qee qhov ua rau pom cov cai?

Yog vim li cas rau tus lej P2145 no suav nrog:

• Quav / txhaws EGR system (EGR valve)
• Kev tso pa tawm rov ua pa qhov cua solenoid valve puas
• Cov pa tso pa tawm rov qhib qhov quav
• Nqus tawm
• Twisted lub tshuab nqus tsev kab
• Teeb meem txuas
• Teeb meem thaiv (qhib Circuit, corrosion, puas, luv Circuit Court, thiab lwm yam)
• Qhov teeb meem ECM

Dab tsi yog qee cov kauj ruam txhawm rau txheeb xyuas thiab daws teeb meem P2145?

Thawj kauj ruam hauv txheej txheem daws teeb meem yog los tshuaj xyuas cov ntawv xov xwm kev pabcuam (TSBs) kom paub cov teeb meem nrog lub tsheb tshwj xeeb.

Cov txheej txheem kuaj mob tau dhau los ua lub tsheb tshwj xeeb thiab yuav xav tau cov cuab yeej tsim nyog thiab kev paub kom tau ua kom raug. Peb piav qhia cov theem pib hauv qab no, tab sis hais txog koj lub tsheb / ua / qauv / kev kho cov ntawv kho mob rau cov qib tshwj xeeb rau koj lub tsheb.

Kauj ruam yooj yim # 1

Thawj qhov koj yuav tsum tau ua yog cia koj lub tsheb lub cav txias. Feem ntau, EGR cov txheej txheem kub heev vim tias lawv feem ntau tau teeb tsa ncaj qha rau ntawm lub tshuab tso pa. Txawm li cas los xij, yog tias koj tsis tso cai rau lub cav kom txias kom zoo, koj yuav raug kub hnyiab. Raws li tau hais dhau los, EGR li qub feem ntau tau teeb tsa ncaj qha rau ntawm qhov tso pa. Cov cua tshuab cua uas tswj qhov cua ntawm EGR qhov system tau teeb tsa nyob txhua qhov chaw hauv lub cav cav, feem ntau ntawm lub firewall. Feem ntau hais lus, lub qhov hluav taws xob solenoid yog qhov nqus nqus solenoid sib txawv, yog li ntau lub tshuab nqus roj hmab tuaj yeem khiav ntawm nws mus rau EGR system.

Nco ntsoov sov li cas nyob ntawm no? Cov kab nqus no tsis tuaj yeem tiv qhov kub tau zoo, yog li nco ntsoov tshuaj xyuas cov kab no kom zoo thaum saib ib puag ncig koj ib puag ncig. Ib txoj kab uas raug hlawv lossis tawg yuav tsum tau hloov lossis kho. Cov kab ntawv tsis kim, yog li kuv ib txwm pom zoo kho dua txhua kab nrog cov tshiab, tshwj xeeb tshaj yog tias koj pom tias ib qho ntawm lawv tsis raug xaj, yog tias ib qho ntawm lawv tsis raug xaj, feem ntau yuav yog, lwm tus tsuas yog nyob ib puag ncig.

Kauj ruam yooj yim # 2

Nco ntsoov ua tib zoo txheeb xyuas qhov ncaj ncees ntawm txoj siv txoj siv sia. Lawv khiav nrog thiab nyob ib ncig ntawm cov yeeb nkab tso tawm, yog li nws yuav yog lub tswv yim zoo los khi ib qho xaim xaim lossis txoj hlua txoj hlua. Yog tias koj pom cov hlua hluav taws kub hnyiab thiab / lossis xaim, muab cov hlua txuas sib txuas thiab xyuas kom tseeb tias lawv raug thaiv kom raug. Txheeb xyuas qhov nqus cua rau qhov tawg thiab / lossis nkag mus rau hauv dej. Xav txog qhov tseeb tias cov ntsuas no tau nthuav tawm rau cov khoom thiab ua los ntawm yas, rau feem ntau, koj yuav tsum paub txog qee qhov ua tau tsis raug. Tsis tas li, nco ntsoov tias cov khoom txuas tau txuas nrog hluav taws xob kom raug thiab tias cov tab tsis ua haujlwm thiab tsis tawg.

Kauj ruam yooj yim # 3

Yog tias muaj thiab yooj yim, koj tuaj yeem tshem lub qhov tso pa rov qab los txhawm rau tshuaj xyuas nws qhov mob. Cov li qub no raug rau cov ntsiab lus soot tseem ceeb. Siv lub tshuab nqus tsev carburetor thiab txhuam hniav kom tshem cov hmoov av tawm ntawm qhov chaw mus-mus tau yooj yim.
