P0129 Barometric siab tsawg dhau

P0129 – OBD-II Teeb meem Code Technical Description

Atmospheric siab tsawg heev

Thaum nws los txog rau qhov teeb meem code P0129, barometric siab plays lub luag haujlwm tseem ceeb. Cov huab cua qis tuaj yeem ua rau muaj kev txhawj xeeb, tshwj xeeb tshaj yog thaum taug kev ntawm qhov siab siab. Koj puas tau pom qhov no ntawm qhov siab li qub? Yuav ua li cas thaum qhov no tshwm sim? Koj tuaj yeem tshem tawm cov tsos mob li cas? Tshawb nrhiav txhua yam koj xav paub txog P0129 code.

Qhov teeb meem code P0129 txhais li cas?

Thawj "P" nyob rau hauv qhov kev kuaj mob teeb meem code (DTC) qhia txog qhov system uas tus lej siv. Nyob rau hauv cov ntaub ntawv no, nws yog kis tau tus mob system (cav thiab kis tau tus mob). Tus cim thib ob "0" qhia tias qhov no yog qhov teeb meem dav dav OBD-II (OBD2). Lub cim thib peb "1" qhia tias muaj kev ua haujlwm tsis zoo hauv cov roj thiab cua ntsuas qhov system, nrog rau hauv cov khoom siv hluav taws xob emission tswj. Ob lub cim kawg “29” sawv cev rau tus lej DTC tshwj xeeb.

yuam kev code P0129 txhais tau hais tias lub barometric siab yog tsawg dhau. Qhov no tshwm sim thaum lub powertrain tswj module (PCM) pom lub siab uas qis dua tus tsim khoom tsim nqi. Hauv lwm lo lus, P0129 code tshwm sim thaum lub manifold cua siab (MAP) sensor lossis barometric cua siab (BAP) sensor yog faulty.

Code P0129 loj npaum li cas?

Qhov teeb meem no tsis tseem ceeb rau lub sijhawm no. Txawm li cas los xij, nws yog ib qho tseem ceeb kom tsis tu ncua xyuas nws yog nyob rau hnub thiab kho nws ua ntej kom tsis txhob muaj teeb meem loj dua.

* Txhua lub tsheb yog qhov tshwj xeeb. Cov yam ntxwv txhawb nqa los ntawm Carly txawv ntawm lub tsheb qauv, xyoo, kho vajtse, thiab software. Txuas lub scanner mus rau OBD2 chaw nres nkoj, txuas rau daim ntawv thov, ua qhov kev kuaj mob thawj zaug thiab xyuas seb cov haujlwm twg muaj rau koj lub tsheb. Thov nco ntsoov tias cov ntaub ntawv muab rau hauv qhov chaw no yog rau cov ntaub ntawv xov xwm nkaus xwb thiab yuav tsum tau siv ntawm koj tus kheej txaus ntshai. Mycarly.com tsis yog lub luag haujlwm rau kev ua yuam kev lossis kev tso tseg lossis rau cov txiaj ntsig tau los ntawm kev siv cov ntaub ntawv no.

Txij li qhov teeb meem no tuaj yeem ua rau lub cav tsis zoo thiab cov pa roj nkag mus rau hauv lub tsheb sab hauv, nws yog ib qho tseem ceeb los kho nws sai li sai tau thaum cov tsos mob saum toj no tshwm sim.

Cov tsos mob ntawm tus lej P0129 yog dab tsi

Koj tuaj yeem xav tias qhov yuam kev no yog tias koj pom cov tsos mob hauv qab no:

1. Xyuas seb lub cav lub teeb yog nyob rau.
2. Pom zoo siv roj ntau.
3. Lub cav ua haujlwm tsis zoo.
4. Cav misfiring.
5. Kev hloov pauv hauv lub cav ua haujlwm thaum lub sijhawm acceleration.
6. Cov pa emissions dub pa luam yeeb.

Yog vim li cas rau code P0129

Tej yam ua tau rau cov cai no suav nrog:

1. Corroded MAF / BPS sensor connector nto.
2. Lub tshuab nqus tsev tsis txaus vim lub cav hnav, misfire lossis clogged catalytic converter.
3. Faulty BPS (manifold cua siab sensor).
4. Qhib lossis luv MAP thiab/lossis BPS sensor thaiv.
5. Tsis txaus system grounding ntawm MAF/BPS.
6. Faulty PCM (engine control module) lossis PCM programming yuam kev.
7. Malfunction ntawm lub manifold cua siab sensor.
8. Lub barometric cua siab sensor yog faulty.
9. Teeb meem nrog kev xaim lossis cov khoom sib txuas.
10. Corrosion ntawm lub connector nto ntawm ib qho ntawm cov sensors.
11. Clogged catalytic converter.
12. Tsis muaj qhov system grounding ntawm lub sensors.

PCM thiab BAP sensor

Atmospheric siab sib txawv nyob rau hauv kev faib ua feem rau altitude saum toj no hiav txwv theem. Lub barometric cua siab (BAP) sensor plays lub luag haujlwm tseem ceeb hauv kev tso cai rau lub cav tswj module (PCM) los saib xyuas cov kev hloov no. PCM siv cov ntaub ntawv los ntawm BAP los tswj cov roj xa tawm thiab thaum lub cav pib.

Ntxiv mus, qhov siv hluav taws xob, roj teeb hauv av, thiab ib lossis ntau qhov hluav taws xob tso zis hluav taws xob raug xa mus rau qhov ntsuas ntsuas barometric siab. BAP kho qhov hluav taws xob siv hluav taws xob thiab hloov qhov kev tiv thaiv raws li qhov ntsuas barometric tam sim no.

Thaum koj lub tsheb nyob ntawm qhov siab siab, lub siab barometric hloov pauv thiab yog li cov qib tsis kam ntawm BAP hloov, uas cuam tshuam rau qhov hluav taws xob xa mus rau PCM. Yog tias PCM pom tias qhov hluav taws xob hluav taws xob los ntawm BAP tsawg dhau, nws yuav ua rau P0129 code tshwm.

Yuav kuaj xyuas thiab kho li cas P0129 code?

Txoj kev daws teeb meem rau P0129 code tuaj yeem sib txawv heev nyob ntawm lub tsheb tsim, vim tias cov lus qhia tshwj xeeb ntawm BAP thiab MAP sensors tuaj yeem sib txawv heev. Piv txwv li, cov txheej txheem rau kev daws teeb meem P0129 ntawm Hyundai yuav tsis tsim nyog rau Lexus.

Txhawm rau kuaj xyuas qhov yuam kev, koj yuav xav tau lub tshuab luam ntawv, lub tshuab hluav taws xob digital / ohmmeter thiab lub tshuab nqus tsev ntsuas. Ua raws li cov kauj ruam no yuav pab koj kuaj xyuas thiab txiav txim siab cov txheej txheem kho tsim nyog:

1. Pib nrog kev tshuaj xyuas qhov muag txhawm rau txheeb xyuas cov kab hluav taws xob puas thiab cov khoom sib txuas. Txhua qhov kev puas tsuaj uas pom yuav tsum tau kho ua ntej kuaj mob ntxiv.
2. Txij li thaum lub roj teeb tsis tshua muaj hluav taws xob tuaj yeem ua rau P0129, xyuas lub roj teeb muaj peev xwm thiab lub davhlau ya nyob twg.
3. Sau tag nrho cov lej los xyuas kom meej tias qhov teeb meem tsuas yog nrog cov sensors hais thiab cov kab ke, tshem tawm lwm yam teeb meem tshwm sim.
4. Ua lub tshuab nqus tsev kuaj xyuas lub cav. Nco ntsoov tias yav dhau los lub cav ntws cov teeb meem xws li daig catalytic converters, txwv tsis pub siv lub tshuab, thiab roj tsawg kuj tuaj yeem cuam tshuam rau lub tshuab nqus tsev.
5. Yog tias tag nrho cov sensors thiab circuits nyob rau hauv cov chaw tsim khoom tshwj xeeb, xav tias PCM tsis raug lossis PCM software.
6. Txhua qhov kev puas tsuaj pom nyob rau hauv cov xov hlau thiab cov khoom sib txuas yuav tsum tau kho.

Ua raws li cov kauj ruam no yuav pab koj kuaj xyuas tau zoo thiab daws qhov teeb meem yuam kev P0129 ntawm koj lub tsheb.

Nws raug nqi npaum li cas los kho tus lej P0129?

Kev txheeb xyuas tus lej yuam kev P0129 tuaj yeem yog cov txheej txheem siv sijhawm thiab feem ntau raug nqi ntawm 75 thiab 150 euros ib teev. Txawm li cas los xij, cov nqi ua haujlwm yuav txawv nyob ntawm qhov chaw thiab ua ntawm koj lub tsheb.

Koj puas tuaj yeem kho qhov chaws koj tus kheej?

Nws yog ib txwm zoo dua los nrhiav kev pab cuam raws li kev daws teeb meem yuav tsum muaj qee theem ntawm kev paub. Qhov no kuj yog vim qhov yuam kev code qee zaum nrog rau ntau lwm yam teeb meem codes. Txawm li cas los xij, yog tias koj muaj cov tsos mob, koj tuaj yeem kuaj xyuas thiab nrhiav kev pab thaum ntxov.
