Txheem
P1250 – OBD-II Teeb meem Code Technical Description
Teeb meem code P1250 qhia tias cov roj theem hauv lub tank tsawg dhau hauv Volkswagen, Audi, Skoda, thiab Seat tsheb.
Qhov txhaum cai txhais li cas P1250?
Teeb meem code P1250 qhia tias muaj teeb meem nrog cov roj tank qib sensor. Qhov no txhais tau hais tias lub teeb liab los ntawm cov roj tank qib sensor mus rau ECU yog qis dua qhov xav tau, uas yuav qhia tau tias muaj teeb meem tsis zoo, kev puas tsuaj, lossis cov roj tsis raug hauv lub tank.
Tej zaum ua rau
Qee qhov ua tau rau P1250 teeb meem code yog:
- Roj qib sensor ua haujlwm tsis zoo: Lub sensor nws tus kheej yuav ua puas los yog ua tsis tiav vim hnav, corrosion, los yog lwm yam teeb meem, uas ua rau ib tug tsis ncaj ncees lawm roj theem teeb liab.
- Kev puas tsuaj rau cov xaim lossis hluav taws xob sib txuas: Cov teeb meem thaiv, tawg lossis luv luv hauv hluav taws xob hluav taws xob nruab nrab ntawm cov roj qib sensor thiab ECU tuaj yeem tiv thaiv cov teeb liab ib txwm muaj.
- Kev teeb tsa tsis raug lossis calibration ntawm roj qib sensor: Yog tias lub sensor tsis ntev los no tau hloov lossis muab kev pabcuam, kev teeb tsa tsis raug lossis tsis raug calibration yuav ua rau kev nyeem ntawv tsis raug.
- Mechanical teeb meem nrog cov roj tank: Kev puas tsuaj los yog tsis xws luag hauv lub tank roj, xws li khoov, dents, lossis blockages, tuaj yeem tiv thaiv cov roj qib sensor ua haujlwm kom raug.
- ECU teeb meem: Kev ua haujlwm tsis zoo lossis ua haujlwm tsis zoo hauv chav tswj lub cav (ECU) tuaj yeem ua rau kev txhais tsis raug ntawm lub teeb liab los ntawm cov roj qib sensor.
- Lwm cov khoom siv yog faulty: Qee yam khoom siv, xws li relays, fuses, los yog lwm cov modules uas tswj cov roj theem sensor Circuit Court, kuj yuav ua rau P1250 code.
Nws yog ib qho tseem ceeb uas yuav tsum tau ua qhov kev kuaj mob kom raug txhawm rau txiav txim siab qhov ua rau ntawm P1250 code hauv ib lub tsheb tshwj xeeb thiab ua kom raug kho kom raug.
Cov tsos mob ntawm tus lej yuam kev yog dab tsi? P1250?
Cov tsos mob rau P1250 teeb meem code tuaj yeem sib txawv thiab suav nrog cov hauv qab no:
- Cov roj nyeem tsis raug: Lub ntsuas ntsuas vaj huam sib luag tuaj yeem tso saib cov roj tsis raug, uas tsis sib haum rau qib tiag tiag hauv lub tank. Qhov no tej zaum yuav yog ib tug tsis txaus los yog ib tug overestimated tus nqi.
- Malfunction ntawm qhov taw qhia roj theem: Qhov taw qhia roj theem ntawm lub ntsuas vaj huam sib luag yuav tsis ua haujlwm zoo, xws li flashing, tsis hloov thaum roj ntxiv lossis tshem tawm, lossis qhia qhov tsis raug.
- Cov cwj pwm txawv txawv thaum refueling: Thaum refueling, lub tank los yog roj muab tub lim caj dab yuav hnov qhov tsis raug, xws li cov roj tsis siv neeg lub tshuab ua haujlwm ua haujlwm ntxov.
- "Check Engine" yuam kev tshwm: Yog tias cov roj qib sensor tau tshaj tawm cov ntaub ntawv tsis raug lossis muaj teeb meem nrog cov hluav taws xob hluav taws xob, lub cav tswj lub cav yuav qhib lub teeb "Check Engine" yuam kev ntawm lub ntsuas hluav taws xob.
- Kev ua haujlwm tsis ruaj khov ntawm lub cav: Qee zaum, txawm tias tsawg dua, cov roj tsis raug hauv lub tank lossis cov ntaub ntawv tsis raug los ntawm cov roj qib sensor tuaj yeem cuam tshuam rau kev ua haujlwm ntawm lub cav, ua rau kev ua haujlwm tsis zoo lossis txawm tias muaj peev xwm poob.
Cov tsos mob no tuaj yeem tshwm sim txawv ntawm cov tsheb sib txawv thiab tuaj yeem tshwm sim tsis yog los ntawm P1250 code, tab sis kuj los ntawm lwm cov teeb meem roj. Yog tias koj pom ib qho ntawm cov tsos mob no, nws raug nquahu kom koj hu rau tus kws kho tsheb uas tsim nyog rau kev kuaj mob thiab kev daws teeb meem.
Yuav ua li cas kuaj tau tus lej txhaum P1250?
Txhawm rau kuaj xyuas DTC P1250, ua raws li cov kauj ruam no:

- Kev xeem thiab kev xeem ntxiv: Yog tias tsim nyog, ua cov kev sim thiab kev sim ntxiv, xws li tshuaj xyuas lub tank siab, xyuas seb muaj huab cua dampers lossis li qub, kuaj xyuas qhov xwm txheej ntawm lub tank roj, thiab lwm yam.
Tom qab kuaj xyuas thiab txheeb xyuas qhov ua rau ntawm qhov yuam kev P1250, koj tuaj yeem pib kho qhov tsim nyog lossis hloov qhov chaw. Yog tias koj tsis tuaj yeem kuaj xyuas lossis kho koj tus kheej, nws raug nquahu kom koj hu rau tus kws kho tsheb tsim nyog lossis chaw pabcuam.
Kev kuaj mob yuam kev
Thaum kuaj pom DTC P1250, cov teeb meem hauv qab no yuav tshwm sim:
- Hla cov kauj ruam tseem ceeb: Ua tsis tiav lossis ploj lawm cov txheej txheem kuaj xyuas tseem ceeb, xws li kuaj xyuas cov hluav taws xob sib txuas lossis kuaj xyuas cov xwm txheej ntawm cov roj qib sensor, tuaj yeem ua rau cov lus txiav txim tsis raug txog qhov ua rau qhov yuam kev.
- Kev txhais cov ntaub ntawv tsis raug: Kev tsis muaj peev xwm lossis tsis nkag siab txog cov ntaub ntawv kuaj mob yuav ua rau muaj kev txhais lus tsis raug ntawm cov tsos mob lossis ua rau yuam kev.
- Hloov cov khoom tsis muaj kev kuaj mob: Tsuas yog hloov cov roj qib sensor lossis lwm yam khoom siv yam tsis tau kuaj pom thawj zaug nws yuav ua rau hloov qhov tsis tsim nyog lossis tsis muaj kev puas tsuaj, uas yuav tsis daws qhov teeb meem.
- Kev tsim nyog tsis txaus: Tsis muaj kev paub dhau los lossis kev tsim nyog yuav ua rau muaj kev tshuaj xyuas cov ntaub ntawv tsis raug thiab cov lus xaus tsis raug txog qhov ua rau yuam kev.
- Siv cov cuab yeej kuaj mob tsis raug: Kev siv cov khoom siv tshuaj ntsuam xyuas tsis raug lossis tsis raug ntsuas yuav ua rau cov ntaub ntawv tsis raug thiab cov lus xaus tsis raug.
- Tsis quav ntsej tej yam tseem ceeb: Qee qhov teeb meem, xws li kev puas tsuaj rau lub tank roj lossis kev ua haujlwm tsis zoo ntawm lwm cov khoom, tuaj yeem cuam tshuam rau kev ua haujlwm ntawm cov roj qib sensor thiab yuav tsum tau coj mus rau hauv tus account thaum kuaj.
Txhawm rau zam qhov yuam kev no, nws yog ib qho tseem ceeb uas yuav tsum ua raws li cov txheej txheem kuaj mob kom raug thiab sab laj cov ntaub ntawv txhim khu kev qha.
Txoj cai txhaum loj npaum li cas? P1250?
Teeb meem code P1250 los ntawm nws tus kheej tsis yog ib qho kev txhaum cai uas tam sim ntawd ua rau muaj kev pheej hmoo rau kev nyab xeeb lossis kev ua haujlwm ntawm lub tsheb. Txawm li cas los xij, nws qhia tau hais tias muaj teeb meem nrog cov roj qib sensor, uas tuaj yeem cuam tshuam qhov tseeb cov zaub ntawm cov roj seem ntawm lub ntsuas vaj huam sib luag thiab kev tswj cov roj hluav taws xob.
Cov ntaub ntawv tsis raug los ntawm cov roj qib sensor tuaj yeem ua rau kev suav tsis raug ntawm cov roj seem, uas tuaj yeem ua rau muaj peev xwm tawm hauv lub tsheb ntawm txoj kev vim tsis muaj roj lossis tsis xav tau refueling vim tsis muaj cov cim qhia txog lub tank khoob.
Tsis tas li ntawd, yog tias qhov ua rau ntawm P1250 code tsis raug kho, nws tuaj yeem ua rau muaj teeb meem ntxiv rau cov roj thiab kev tswj lub cav, uas tuaj yeem cuam tshuam qhov kev ua tau zoo thiab kev ntseeg siab ntawm lub tsheb.
Yog li ntawd, txawm hais tias P1250 code nws tus kheej tsis yog qhov tseem ceeb hauv thawj qhov chaw, nws raug nquahu kom kuaj xyuas thiab kho qhov teeb meem sai li sai tau kom tsis txhob muaj qhov tshwm sim thiab ua kom muaj kev ntseeg siab thiab ua haujlwm ntawm koj lub tsheb.
Kev kho dab tsi yuav pab tshem tawm cov cai? P1250?
Kev daws qhov teeb meem ntawm P1250 yuav xav tau ntau yam kev kho, nyob ntawm seb qhov ua rau qhov yuam kev. Cov hauv qab no yog cov kev kho tseem ceeb:
- Hloov cov roj theem sensor: Yog tias cov roj qib sensor ua tsis tiav lossis muab cov cim tsis raug, hloov lub sensor yuav daws tau qhov teeb meem. Lub sensor tshiab yuav tsum yog cov khoom zoo thiab ua tau raws li cov chaw tsim khoom tshwj xeeb.
- Kev tshuaj xyuas thiab kho cov kev sib txuas hluav taws xob: Ua kom paub meej txog kev sib txuas hluav taws xob thiab cov xov hlau txuas nrog cov roj qib sensor. Yog tias tsim nyog, hloov cov kev sib txuas puas lossis oxidized thiab kho cov hlua.
