P0851 Chaw Nres Tsheb / Nruab Nrab Txoj Haujlwm Hloov Chaw Nkag Tawm Circuit Tsawg

P0851 – OBD-II Teeb meem Code Technical Description

Teeb meem code P0851 qhia tias Park/Neutral position switch input circuit is low.

Qhov txhaum cai txhais li cas P0851?

Teeb meem code P0851 qhia tias Park/Neutral Position (PNP) hloov input Circuit Court yog tsawg. Kuj tseem hu ua PRNDL ntawm kev sib kis tsis siv neeg, qhov hloov pauv no tswj hwm lub tsheb lub iav txoj haujlwm, suav nrog chaw nres tsheb thiab chaw nruab nrab. Thaum ECM pom tias lub teeb liab los ntawm PNP hloov qis dua qhov xav tau, nws tsim teeb meem code P0851.

Tej zaum ua rau

Ua tau ntawm DTC P0851:

• Park/Neutral Position (PNP) Hloov ua haujlwm tsis zoo: Hloov nws tus kheej tuaj yeem raug puas los yog ua yuam kev, ua rau nws cov xwm txheej nyeem tsis raug.
• Cov kab hluav taws xob puas lossis tawg: Cov xaim txuas ntawm PNP hloov mus rau lub cav tswj module tuaj yeem raug puas los yog tawg, ua rau muaj teeb meem qis.
• Corrosion los yog oxidation ntawm kev sib cuag: Buildup los yog corrosion nyob rau hauv cov kev sib cuag los yog connectors yuav ua rau lub teeb liab tsis tau nyeem kom raug thiab yog li ua rau P0851 code tshwm.
• Teeb meem nrog lub cav tswj module (PCM): Kev ua haujlwm tsis zoo hauv PCM, uas tswj cov teeb liab los ntawm PNP hloov, kuj tuaj yeem ua rau qhov yuam kev.
• Teeb meem hauv av los yog av: Cov av tsis txaus lossis teeb meem hauv av hauv lub cev tuaj yeem ua rau lub teeb liab qis thiab, vim li ntawd, tus lej P0851.
• Teeb meem nrog lwm lub tsheb: Qee lwm lub tsheb lossis cov khoom siv, xws li lub roj teeb lossis lub tshuab hluav taws xob, tuaj yeem cuam tshuam kev ua haujlwm ntawm PNP hloov thiab ua rau qhov yuam kev no tshwm sim.

Txhawm rau kuaj xyuas thiab kho qhov teeb meem kom raug, nws raug nquahu kom koj hu rau tus kws kho tsheb tsim nyog lossis chaw pabcuam.

Cov tsos mob ntawm tus lej yuam kev yog dab tsi? P0851?

Cov tsos mob rau DTC P0851 yuav suav nrog cov hauv qab no:

• Iav hloov teeb meem: Lub tsheb yuav tsis tuaj yeem hloov mus rau lub zog xav tau lossis tsis tuaj yeem hloov pauv txhua. Qhov no yuav ua rau lub tsheb tsis pib lossis txav tsis tau.
• Tsis muaj peev xwm pib lub cav hauv chaw nres tsheb lossis nruab nrab: Yog tias qhov hloov pauv PNP tsis ua haujlwm raug, lub tsheb yuav tsis pib thaum lub teeb hluav taws xob tig mus rau txoj haujlwm "START" lossis yuav tsum nyob hauv txoj haujlwm "P" lossis "N".

Tom qab txheeb xyuas qhov ua rau yuam kev P0851, koj yuav tsum pib tshem tawm nws.

Kev kuaj mob yuam kev

Thaum kuaj pom DTC P0851, cov teeb meem hauv qab no yuav tshwm sim:

• Tsis muaj kev saib xyuas rau cov xaim thiab cov khoom sib txuas: Yog tias cov xaim thiab cov khoom sib txuas tsis tau raug kuaj xyuas kom zoo lossis tsis pom muaj teeb meem, nws yuav ua rau qhov ua rau yuam kev.
• Txiav tawm lwm qhov ua tau: Kev tsom mus rau PNP nkaus xwb thiab tsis xav txog lwm yam ua tau, xws li teeb meem nrog ECM lossis corrosion ntawm cov khoom sib txuas, kuj tuaj yeem ua rau tsis zoo.
• Kev txhais tsis tseeb ntawm qhov tshwm sim: Kev txhais tsis raug ntawm cov txiaj ntsig kev xeem lossis kev ntsuas ntawm PNP hloov lossis xaim kuj tuaj yeem ua rau tsis raug.
• Kev kuaj mob tsis zoo ntawm lwm cov khoom: Kev kuaj mob tsis txaus ntawm lwm cov kab ke sib kis, xws li lub cav tswj module lossis sensors, yuav ua rau tsis muaj teeb meem ntxiv uas yuav cuam tshuam nrog P0851 code.
• Tsis quav ntsej txog qib thiab qhov xwm txheej ntawm cov kua dej sib kis: Tsis kuaj xyuas cov dej sib kis thiab qhov xwm txheej yuav ua rau muaj teeb meem ploj uas yuav cuam tshuam rau kev ua haujlwm ntawm PNP hloov.
• Kev tsis txaus siab rau cov kws tshaj lij: Yog tias kev kuaj mob tau ua los ntawm ib tus kws kho tsheb tsis muaj kev tshaj lij lossis tsis tsim nyog, nws yuav ua rau cov lus txiav txim tsis raug thiab kho tsis raug.

Txhawm rau kuaj xyuas tau zoo thiab daws qhov teeb meem ntawm P0851, nws yog ib qho tseem ceeb uas yuav tau hu rau tus kws kho tsheb lossis chaw pabcuam, tshwj xeeb tshaj yog tias koj ntsib teeb meem lossis tsis paub tseeb thaum lub sijhawm kuaj mob.

Txoj cai txhaum loj npaum li cas? P0851?

Teeb meem code P0851 qhia tias muaj teeb meem nrog Park/Neutral Position (PNP) hloov, uas yog ib qho tseem ceeb ntawm kev tswj kev sib kis. Nyob ntawm seb qhov hloov pauv lossis cov xaim puas raug puas tsuaj, qhov teeb meem no tuaj yeem muaj qhov txawv txav. Qhov hnyav ntawm P0851 chaws yuav siab vim yog cov hauv qab no:

• nres tsheb: Yog tias lub tsheb tsis tuaj yeem pib lossis hloov mus rau hom kev mus los vim muaj teeb meem nrog PNP hloov, nws yuav ua rau lub tsheb nres, uas yuav ua rau tsis yooj yim lossis txaus ntshai ntawm txoj kev.
• Tsis muaj peev xwm hloov cov iav kom raug: PNP hloov txoj haujlwm tsis raug lossis tsis ua haujlwm yuav ua rau lub tsheb tsis tuaj yeem hloov mus rau hauv lub iav kom raug, uas yuav ua rau tsis muaj kev tswj xyuas lub tsheb.
• Tsis muaj peev xwm siv kev ruaj ntseg thiab kev nyab xeeb: Kev ua haujlwm tsis raug ntawm PNP hloov kuj tseem tuaj yeem ua rau qee lub tsheb ruaj khov lossis kev nyab xeeb tsis muaj, uas yuav ua rau muaj kev pheej hmoo ntawm kev sib tsoo.
• Tsis muaj peev xwm pib lub cav hauv qhov chaw nyab xeeb: Yog tias qhov hloov pauv PNP tsis ua haujlwm raug, nws yuav ua rau lub tsheb pib hauv hom tsis tsim nyog, uas yuav ua rau muaj kev sib tsoo lossis kev puas tsuaj rau kev sib kis.

Raws li cov xwm txheej no, P0851 teeb meem code yuav tsum raug txiav txim siab loj thiab yuav tsum tau kuaj xyuas thiab kho sai li sai tau txhawm rau ua kom muaj kev nyab xeeb thiab ua haujlwm zoo ntawm lub tsheb.

Kev kho dab tsi yuav pab tshem tawm cov cai? P0851?

Kev daws teeb meem teeb meem code P0851 tuaj yeem koom nrog ob peb kauj ruam:

1. Hloov PNP hloov: Yog hais tias qhov chaw nres tsheb/Neutral Position (PNP) hloov yog tiag tiag faulty, nws yuav tsum tau hloov nrog ib tug tshiab thawj los yog zoo hloov.
2. Kho lossis hloov cov hlau puas: Yog tias muaj kev puas tsuaj los yog tawg nyob rau hauv cov xaim txuas PNP hloov mus rau lub cav tswj module, cov xov hlau sib txuas yuav tsum tau kho lossis hloov.
3. Ntxuav lossis hloov cov khoom sib txuas: Yog tias pom muaj corrosion los yog oxidation ntawm cov pins connector, lawv yuav tsum tau ntxuav los yog hloov.
4. Diagnostics thiab hloov lub cav tswj module: Yog tias tag nrho cov kauj ruam dhau los tsis daws qhov teeb meem, qhov teeb meem yuav yog nrog lub cav tswj module (PCM). Hauv qhov no, nws yog ib qho tsim nyog yuav tsum tau kuaj xyuas ntxiv thiab, yog tias tsim nyog, hloov PCM.
5. Kev kuaj xyuas thiab kev pabcuam kev sib kis: Tom qab kho qhov teeb meem hloov PNP, koj yuav tsum tau kuaj xyuas qhov xwm txheej thiab kev ua haujlwm ntawm lwm yam ntawm cov kab ke sib kis kom txiav txim siab txog cov teeb meem tshwm sim.

Nws raug nquahu kom kuaj xyuas thiab kho los ntawm tus kws kho tsheb uas tsim nyog lossis lub chaw pabcuam raug tso cai los xyuas kom meej tias qhov teeb meem raug kho kom raug thiab lub tsheb rov qab ua haujlwm zoo.
