P0845 Kev ua haujlwm tsis zoo ntawm cov hluav taws xob hluav taws xob ntawm qhov kis tau tus mob siab sensor "B"

P0845 – OBD-II Teeb meem Code Technical Description

Teeb meem code P0845 qhia tias muaj kev ua haujlwm tsis zoo hauv kev sib kis cov kua dej siab sensor "B" Circuit Court.

Qhov txhaum cai txhais li cas P0845?

Teeb meem code P0845 qhia tias tsis siv neeg kis tau tus mob tswj module (PCM) tau kuaj pom qhov txawv txav voltage nyeem los ntawm kis tau tus mob kua siab sensor B. Qhov kev ua yuam kev no feem ntau nrog rau lwm cov lej ntsig txog lub zog hloov pauv lub kaw lus, hloov solenoid valve, iav slippage, iav piv los yog kaw. Ntau yam sensors yog siv los txiav txim siab qhov xav tau rau kev sib kis kom ua haujlwm. Yog tias cov kua dej siab sensor tsis pom lub siab kom raug, nws txhais tau hais tias qhov xav tau kev sib kis ntawm cov kua siab tsis tuaj yeem ua tiav. Hauv qhov no, qhov yuam kev P0845 tshwm sim.

Tej zaum ua rau

Qee qhov ua rau muaj teeb meem code P0845:

Yuav ua li cas kuaj tau tus lej txhaum P0845?

Txhawm rau kuaj xyuas qhov teeb meem code P0845, ua raws li cov kauj ruam no:

1. Txheeb xyuas cov kev sib txuas thiab kev xaim: Ua ntej ntawm tag nrho cov, xyuas cov xwm txheej ntawm tag nrho cov kev sib txuas hluav taws xob thiab cov xov hlau cuam tshuam nrog kev sib kis ntawm cov kua dej siab sensor. Nco ntsoov tias tag nrho cov kev sib cuag tau ruaj ntseg thiab tsis muaj cov cim qhia ntawm corrosion los yog oxidation.
2. Txheeb xyuas qhov kis tau tus mob siab sensor: Siv lub multimeter los xyuas qhov tsis kam thiab qhov hluav taws xob ntawm qhov kis tau tus mob siab sensor. Xyuas kom tseeb tias nws ua haujlwm kom raug thiab tsim cov teeb liab raug.
3. Txheeb xyuas qib thiab qhov xwm txheej ntawm cov kua dej sib kis: Xyuas kom tseeb tias cov dej sib kis nyob rau hauv qhov kev pom zoo thiab xyuas kom muaj kev sib kis los yog impurities.
4. Yuam kev scanning: Siv OBD-II scanner los kuaj xyuas lwm cov lej yuam kev hauv kev tswj hwm lub cav. Cov lej ntxiv tuaj yeem muab cov ntaub ntawv ntxiv txog qhov teeb meem.
5. Txheeb xyuas cov kab thiab cov li qub: Txheeb xyuas qhov xwm txheej thiab kev ua haujlwm ntawm lub tshuab nqus tsev thiab cov li qub uas cuam tshuam nrog kev tswj kev sib kis.
6. Xyuas lub cav tswj module (PCM): Yog tias tag nrho lwm cov khoom siv thiab cov tshuab zoo nkaus li zoo, qhov teeb meem yuav yog nrog PCM nws tus kheej. Nyob rau hauv rooj plaub no, kev kuaj mob thiab kho kev tshaj lij yuav tsum tau ua.

Kev kuaj mob yuam kev

Thaum kuaj pom DTC P0845, cov teeb meem hauv qab no yuav tshwm sim:

• Kev txhais tsis tseeb ntawm cov tsos mob: Qee cov tsos mob, xws li kev hloov pauv hauv kev sib kis tau zoo, yuav raug txhais tsis raug raws li cov teeb meem ntawm kev sib kis ntawm cov kua dej siab sensor. Qhov no yuav ua rau lub sensor hloov tsis tsim nyog.
• Cov teeb meem thaiv kab mob: Qhov yuam kev tuaj yeem yog vim kev ua haujlwm tsis raug ntawm lub tshuab hluav taws xob lossis cov xaim hluav taws xob. Undetected puas nyob ntawm tej los yog faulty hu tuaj yeem ua rau cov lus xaus tsis raug.
• Malfunction ntawm lwm yam Cheebtsam: Cov tsos mob zoo li no tuaj yeem tshwm sim tsis yog los ntawm kev ua txhaum ntawm kev sib kis ntawm cov kua dej siab sensor, tab sis kuj los ntawm lwm yam teeb meem hauv kev sib kis lossis kev tswj hwm lub cav. Piv txwv li, teeb meem nrog li qub, gaskets, lossis kis tau tus kheej tuaj yeem tshwm sim nrog cov tsos mob zoo sib xws.
• Kev txhais tsis raug ntawm cov ntaub ntawv scanner: Cov kws tshaj lij tsis paub qab hau tuaj yeem txhais cov ntaub ntawv scanner yuam kev, uas yuav ua rau muaj kev kuaj mob tsis raug thiab hloov cov khoom tsis raug.
• Teeb meem nrog PCM nws tus kheej: Muaj tsawg zaus, qhov yuam kev tuaj yeem tshwm sim los ntawm qhov tsis raug ntawm lub cav tswj module (PCM) lossis lwm yam khoom siv hluav taws xob cuam tshuam nrog kev tswj kev sib kis.

Txoj cai txhaum loj npaum li cas? P0845?

Teeb meem code P0845 qhia tias muaj teeb meem nrog cov kis tau tus mob siab sensor. Txawm hais tias qhov teeb meem no tsis yog qhov tseem ceeb rau kev nyab xeeb ntawm kev tsav tsheb tam sim ntawd, nws tuaj yeem ua rau muaj teeb meem loj nrog kev sib kis tau zoo, uas tuaj yeem ua rau lub tsheb tsis ua haujlwm. Yog li, nws raug nquahu kom koj ua tam sim ntawd los kuaj xyuas thiab kho qhov teeb meem tom qab P0845 code zoo nkaus li kom tsis txhob muaj kev puas tsuaj ntxiv rau kev sib kis thiab cov teeb meem cuam tshuam.

Kev kho dab tsi yuav pab tshem tawm cov cai? P0845?

Kev daws teeb meem teeb meem code P0845 suav nrog cov kauj ruam hauv qab no:

1. Tshawb xyuas qhov kis tau tus mob siab sensor: Pib los ntawm kev kuaj lub sensor nws tus kheej rau kev puas tsuaj, corrosion, lossis corrosion. Xyuas nws cov kev sib txuas rau luv luv Circuit Court lossis qhib teeb liab.
2. Tshawb xyuas Cov Hluav Taws Xob thiab Cov Hluav Taws Xob: Tshawb xyuas cov xaim los ntawm cov xaim hluav taws xob xa hluav taws xob mus rau PCM rau kev puas tsuaj, qhib, lossis luv. Ua tib zoo tshuaj xyuas thiab xyuas qhov xwm txheej ntawm txhua qhov txuas.
3. Kev Hloov Hloov Sensor: Yog tias pom tias qhov kev sib kis ntawm cov kua dej siab sensor ua yuam kev, hloov nws nrog ib qho tshiab.
4. Tshawb xyuas thiab hloov cov kua xa hluav taws xob: Tshawb xyuas qib thiab qhov xwm txheej ntawm cov kua xa hluav taws xob. Hloov nws yog tias tsim nyog thiab xyuas kom meej tias qib yog lawm.
5. Kev kuaj xyuas thiab rov ua dua PCM: Yog tias tag nrho cov kev ntsuas saum toj no tsis daws qhov teeb meem, PCM yuav tsum tau kuaj xyuas thiab, yog tias tsim nyog, rov ua dua.
6. Kev Xeem Ntxiv: Hauv qee kis, yuav tsum tau ua cov kev sim ntxiv txhawm rau txheeb xyuas lwm yam teeb meem cuam tshuam txog kev sib kis.

Tom qab ua tiav cov kauj ruam no, nws tsim nyog rov pib dua qhov teeb meem code thiab ua qhov kev sim ua kom tiav kom paub tseeb tias qhov teeb meem raug daws. Yog tias qhov chaws tsis tshwm sim dua thiab kev sib kis tau zoo, qhov teeb meem raug txiav txim siab daws.
