P0518 – OBD-II Teeb meem Code Technical Description

Teeb meem code P0518 qhia txog qhov txawv txav ntawm lub teeb liab hauv lub tshuab hluav taws xob tsis siv neeg.

Qhov txhaum cai txhais li cas P0518?

Teeb meem code P0518 qhia tias muaj teeb meem nrog lub cav tsis ua haujlwm ceev. Qhov no txhais tau hais tias lub cav tswj module (PCM) tau kuaj pom qhov tsis sib xws hauv lub cav tsis ua haujlwm, uas yuav siab dhau lossis qis dhau los piv rau qhov ib txwm muaj rau ib lub tsheb tshwj xeeb.

Tej zaum ua rau

Qee qhov laj thawj rau P0518 teeb meem code:

• Tsis muaj teeb meem huab cua ceev sensor (IAC).
• Teeb meem nrog lub throttle txoj hauj lwm sensor (TPS).
• Kev ua haujlwm throttle tsis raug.
• Teeb meem nrog lub coolant kub sensor.
• Malfunctions nyob rau hauv lub lag luam ntawm hluav taws xob Circuit Court txuam nrog sensors thiab actuators uas tswj lub cav ceev.
• Malfunctions nyob rau hauv lub engine tswj module (PCM).
• Teeb meem ntawm lub tsheb lub tshuab hluav taws xob, xws li cov xov hlau tawg lossis luv luv.

Cov tsos mob ntawm tus lej yuam kev yog dab tsi? P0518?

Cov tsos mob rau DTC P0518 yuav suav nrog cov hauv qab no:

• Tsis ruaj tsis khov ceev: Lub cav yuav tsis ruaj khov ntawm qhov tsis ua haujlwm, txhais tau tias qhov nrawm yuav nce lossis poob qis dua li qub.
• Nce idle speed: Lub cav yuav tsis ua haujlwm ntawm qhov nrawm dua, uas yuav ua rau pom kev vibrations lossis suab nrov ntxiv.
• Lub zog poob: Yog hais tias lub sensors thiab actuators uas tswj lub cav ceev yog malfunctioning, muaj teeb meem nrog lub cav fais fab yuav tshwm sim.
• Cov suab tsis zoo los yog kev vibrations: Yog hais tias lub throttle valve los yog lwm yam khoom ntawm lub idle speed control system tsis ua hauj lwm zoo, lub suab txawv txawv los yog vibrations yuav tshwm sim.
• Pib lub cav nrog nyuaj: Tej zaum nws yuav siv sij hawm ntau dua los yog siv zog los pib lub cav vim qhov tsis ruaj khov tsis ua haujlwm.
• Ignition ntawm Check Engine Indicator: Code P0518 activates lub Cheebtsam lub teeb ntawm lub ntsuas vaj huam sib luag, qhia tau hais tias muaj teeb meem tsis ua hauj lwm ceev.

Yuav ua li cas kuaj tau tus lej txhaum P0518?

Txhawm rau kuaj xyuas DTC P0518, cov kauj ruam hauv qab no raug pom zoo:

1. Tshawb xyuas Lub Teeb Tsav Tsheb: Ua ntej, xyuas seb puas muaj lub teeb Check Engine ntawm koj lub dashboard. Yog tias nws los txog, nws yuav qhia tau tias muaj teeb meem nrog lub cav ceev tswj qhov system.
2. Siv OBD-II scanner: Txuas lub OBD-II scanner rau koj lub tsheb qhov chaw kuaj mob thiab nyeem cov lej teeb meem. Xyuas kom tseeb tias tus lej P0518 tau teev tseg.
3. Xyuas cov xov hlau thiab connectors: Tshawb xyuas cov xov hlau thiab cov khoom txuas txuas nrog lub ntsuas hluav taws xob nrawm thiab lub cav tswj module (ECM). Xyuas kom tag nrho cov xov hlau tsis zoo, tsis muaj kev puas tsuaj thiab ruaj ntseg txuas.
4. Txheeb xyuas qhov tsis siv neeg ceev sensor: Tshawb xyuas lub ntsuas ntsuas ntsuas kom tsis txhob muaj kev puas tsuaj lossis corrosion. Xyuas kom tseeb tias nws raug ntsia kom raug thiab ua haujlwm zoo.

Tom qab ua tiav cov kauj ruam no, koj tuaj yeem txheeb xyuas qhov laj thawj thiab daws qhov teeb meem uas ua rau P0518 code.

Kev kuaj mob yuam kev

Thaum kuaj pom DTC P0518, cov teeb meem hauv qab no yuav tshwm sim:

• Kev txhais tsis tseeb ntawm cov tsos mob: Ib qho yuam kev yuav yog kev txhais lus yuam kev ntawm cov tsos mob. Piv txwv li, cov tsos mob uas cuam tshuam nrog lwm yam teeb meem tuaj yeem ua yuam kev los ntawm tus lej teeb meem P0518.
• Omitting cov ntsiab lus tseem ceeb: Cov txheej txheem kuaj mob yuav plam cov khoom tseem ceeb xws li cov xov hlau, cov khoom sib txuas, lossis lub ntsuas hluav taws xob nrawm, uas tuaj yeem ua rau qhov teeb meem raug txheeb xyuas tsis raug.
• Kev daws teeb meem yuam kev: Qee qhov xwm txheej, yog tias qhov kev kuaj mob tsis txaus lossis cov ntaub ntawv tsis raug txheeb xyuas, tus kws kho tsheb yuav muab cov kev daws teeb meem tsis tsim nyog, uas yuav ua rau muaj kev nkim sijhawm ntxiv thiab cov peev txheej.
• Faulty Cheebtsam: Qee lub sij hawm tus kws kho tsheb yuav tsis pom cov khoom tsis zoo xws li qhov tsis siv neeg ceev sensor lossis lub cav tswj module, ua rau muaj kev kuaj tsis raug thiab hloov qhov tsis tsim nyog.
• Kev txawj ntse tsis txaus: Tsis muaj kev paub dhau los lossis kev txawj ntse hauv kev kuaj xyuas lub tshuab hluav taws xob hauv tsheb kuj tuaj yeem ua rau muaj qhov tsis raug thaum kuaj pom tus lej P0518.

Txhawm rau tiv thaiv cov kev ua yuam kev no, nws yog ib qho tseem ceeb uas yuav tsum tau ua kom tiav kev kuaj mob, ua raws li cov txheej txheem kev tshaj lij thiab cov lus pom zoo ntawm cov chaw tsim khoom tsheb.

Txoj cai txhaum loj npaum li cas? P0518?

Idle ceev teeb meem code P0518 tuaj yeem muaj qhov sib txawv ntawm qhov hnyav nyob ntawm seb qhov laj thawj tshwj xeeb thiab cov ntsiab lus ntawm lub tsheb ua haujlwm. Feem ntau, txoj cai no tsis yog qhov tseem ceeb thiab feem ntau tsis ua rau muaj kev phom sij rau kev nyab xeeb tam sim lossis kev tso tseg tam sim ntawm lub tsheb khiav haujlwm.

Txawm li cas los xij, siab lossis qis qis qis tuaj yeem cuam tshuam tsis zoo rau kev ua haujlwm ntawm lub cav, kev ua haujlwm thiab kev lag luam roj. Tsis siv neeg ceev ceev tuaj yeem ua rau lub cav tsis ruaj khov thiab ua rau lub cav nres, tshwj xeeb tshaj yog thaum nres ntawm lub teeb tsheb lossis hauv tsheb khiav. Kev kub ceev tuaj yeem ua rau lub cav tsis tsim nyog hnav thiab siv roj ntau ntxiv.

Tsis tas li ntawd, qhov txhaum uas ua rau P0518 code tuaj yeem muaj kev cuam tshuam rau lwm lub tshuab hauv lub tsheb, uas tuaj yeem ua rau muaj teeb meem loj dua yog tias nws tsis kho raws sijhawm.

Yog li, txawm hais tias tus lej P0518 tsis yog ib qho xwm txheej ceev, nws tseem xav tau kev saib xyuas thiab kho kom raws sijhawm kom tsis txhob muaj teeb meem ntxiv nrog lub cav thiab lwm lub tsheb.

Kev kho dab tsi yuav pab tshem tawm cov cai? P0518?

Txhawm rau daws DTC P0518, ua raws cov kauj ruam no:

1. Tshawb xyuas Idle Air Speed ​​​​Sensor (IAC): Txheeb xyuas qhov xwm txheej thiab kev ua haujlwm ntawm qhov tsis siv neeg ceev sensor. Ntxuav nws ntawm av los yog hloov nws yog tias tsim nyog.
2. Tshawb xyuas cov cua ntws: Txheeb xyuas cov cua lim thiab cua ntws kom ntseeg tau tias cov cua sib xyaw hauv lub piston yog qhov tseeb.
3. Txheeb xyuas qhov Throttle Position Sensor (TPS): Txheeb xyuas qhov ntsuas qhov ntsuas qhov ntsuas kom ua haujlwm kom raug. Ntxuav nws ntawm av los yog hloov nws yog tias tsim nyog.
4. Tshawb xyuas qhov nqus dej: Tshawb xyuas lub tshuab nqus tsev rau cov dej xau uas yuav cuam tshuam rau lub cav idling.
5. Tshawb xyuas cov khoom siv roj: Tshawb xyuas cov twj tso kua mis thiab cov roj twj tso kua mis kom ua haujlwm kom raug. Xyuas kom tseeb tias cov roj system ua haujlwm kom raug thiab muab roj txaus.
6. Txheeb xyuas cov kab hluav taws xob thiab cov khoom sib txuas: Txheeb xyuas cov hlua hluav taws xob thiab cov khoom sib txuas nrog lub ntsuas hluav taws xob nrawm thiab lwm yam sensors kom paub tseeb tias tsis muaj kev tawg lossis xeb.
7. Software firmware (yog tias tsim nyog): Qee zaum, qhov teeb meem yuav cuam tshuam nrog PCM software. Hauv qhov no, koj yuav tsum hloov kho lossis rov kho cov software los kho qhov teeb meem.
8. Kev hloov PCM: Nyob rau hauv tsawg zaus, PCM malfunctions tej zaum yuav muaj feem xyuam rau ib tug malfunction ntawm lub module nws tus kheej. Nyob rau hauv rooj plaub no, PCM yuav tsum tau hloov los yog reprogrammed.

Tom qab ua tiav tag nrho cov kauj ruam no, nws raug nquahu kom koj sim tsav thiab rov kuaj xyuas kom paub meej tias P0518 teeb meem code tsis tshwm sim lawm. Yog tias qhov teeb meem tshwm sim, nws raug nquahu kom koj hu rau tus kws kho tsheb tsim nyog lossis chaw pabcuam kom paub meej ntxiv thiab kho.
