P040C Tsawg teeb liab theem ntawm cov pa roj recirculation kub sensor

OBD-II DTC Cov Ntaub Ntawv

Tsawg teeb liab theem nyob rau hauv cov pa roj recirculation kub sensor Circuit Court

Qhov no txhais li cas?

Qhov no yog ib qho kev kuaj mob Diagnostic Trouble Code (DTC) thiab feem ntau siv rau tsheb OBD-II. Qhov no yuav suav nrog tab sis tsis txwv rau Mazda, VW, Audi, Mercedes Benz, Ford, Dodge, Ram, thiab lwm yam.

Txawm hais tias dav dav, cov txheej txheem kho kom raug yuav txawv nyob ntawm tus qauv xyoo, ua, qauv, thiab kev teeb tsa xa tawm.

Ua ntej qhov ua tau zoo ntawm kev siv cov pa tso pa rov ua dua tshiab hauv cov tsheb hauv xyoo 1970, cov tshuab ua haujlwm nquag siv roj tsis hlawv thiab tso nws mus rau huab cua. Cov hnub no, ntawm qhov tod tes, lub tsheb yuav tsum muaj qee qib kev tso pa thiaj li yuav txuas ntxiv mus.

Kev siv cov pa tso pa rov ua dua tshiab tau ua rau txo qis kev tso pa tawm los ntawm kev rov ua dua tshiab cov pa tawm los ntawm cov pa tso tawm thiab / lossis lwm qhov ntawm cov pa tso tawm thiab rov tsim dua lossis rov hlawv lawv kom ntseeg tau tias peb hlawv cov roj peb them kom muaj txiaj ntsig. los ntawm lawv txoj kev mob siab rau. khwv tau nyiaj!

Kev ua haujlwm ntawm EGR qhov ntsuas kub yog txhawm rau muab txhais rau ECM (lub cav tswj lub tshuab) los saib xyuas EGR qhov kub thiab / lossis kho qhov ntws raws nrog EGR valve. Qhov no tau ua tiav tau yooj yim nrog cov pa ntsuas qhov ntsuas qhov ntsuas kub.

Koj lub OBD (On-Board Diagnostic) cov cuab yeej scan yuav qhia P040C thiab cov lej muaj feem cuam tshuam thaum ECM pom qhov ua haujlwm tsis zoo hauv EGR ntsuas kub lossis nws cov circuits. Raws li kuv tau hais ua ntej, lub kaw lus suav nrog cov pa hluav taws kub, tsis yog li ntawd xwb, tab sis koj tab tom cuam tshuam nrog ib qho ntawm cov chaw kub tshaj plaws hauv lub tsheb, yog li ceev faj koj txhais tes / ntiv tes nyob qhov twg, txawm tias lub cav tawm rau lub sijhawm luv luv. . sij hawm.

P040C Exhaust Gas Recirculation Temperature Sensor Circuit Low yog teem los ntawm ECM thaum kuaj pom hluav taws xob qis hauv EGR "A" kub sensor Circuit Court. Nrog koj phau ntawv kho tsheb tshwj xeeb los txiav txim seb qhov twg ntawm cov saw yog "A" rau koj daim ntawv thov tshwj xeeb.

Dab tsi yog qhov hnyav ntawm DTC no?

Qhov hnyav ntawm no nyob ntawm ntau ntawm koj qhov teeb meem tshwj xeeb, tab sis kuv yuav tsis cais nws raws li qhov hnyav tau muab qhov tseeb tias tag nrho cov kab ke tau nkag mus rau hauv tsheb yooj yim raws li lub tswv yim txo qis. Uas tau hais tias, cov pa tawm tsis zoo "rau koj lub tsheb, lossis tsis xau lossis ua tsis tau zoo EGR qhov ntsuas kub, yog li kev saib xyuas yog qhov tseem ceeb ntawm no sai dua tom qab!

Piv txwv ntawm cov pa tso pa rov ntsuas kub ntsuas:

Cov tsos mob ntawm txoj cai yog dab tsi?

Cov tsos mob ntawm P040C teeb meem cov cai yuav suav nrog:

• Ua tsis tiav lub xeev / xeev cov pa taws los yog kev tso pa tawm
• Lub suab nrov ntawm lub cav (knocking, rattling, ringing, thiab lwm yam)
• Tso zis ntau dua
• Muaj pa tsw qab heev

Dab tsi yog qee qhov ua rau pom cov cai?

Yog vim li cas rau qhov P040C cav code yuav suav nrog:

• Tsis zoo lossis puas EGR qhov ntsuas kub.
• Cov pa roj rov ua dua tshiab ntsuas qhov ntsuas qhov ntsuas roj av
• Cov kab tawg los yog xau tawm hauv qhov chaw uas lub ntsuas tau teeb tsa
• Cov hlua hluav taws kub hnyiab thiab / lossis sensor
• Cov hlau tsis zoo (qhib Circuit, luv rau lub zog, luv rau hauv av, thiab lwm yam)
• Cov khoom puas
• ECM (Engine Control Module) teeb meem
• Kev sib txuas tsis zoo

Dab tsi yog qee cov kauj ruam los daws teeb meem P040C?

Kauj ruam yooj yim # 1

Thawj qhov kuv xav ua ntawm no yog txheeb xyuas txhua yam peb tuaj yeem pom los ntawm qhov pom yooj yim tshuaj xyuas lub sensor thiab ib puag ncig EGR system, tshwj xeeb yog saib rau qhov tso pa tawm. Kuj xyuas lub sensor thiab nws txoj hlua thaum koj nyob ntawd. Nco qab qhov kuv tau hais txog cov kub no? Lawv tuaj yeem ua rau cov yas thiab cov roj hmab puas tsuaj, yog li xyuas lawv kom zoo.

TSWV YIM: Cov hmoov av dub tuaj yeem qhia qhov tso pa tawm sab hauv tsev.

Kauj ruam yooj yim # 2

Ntau qhov teeb meem EGR kuv tau pom yav dhau los tau tshwm sim los ntawm cov hmoov av tsim tawm hauv lub cev, uas tuaj yeem tshwm sim los ntawm ntau qhov laj thawj (kev saib xyuas tsis zoo, tsis zoo roj, thiab lwm yam). Qhov no tsis muaj qhov tshwj xeeb hauv qhov no, yog li nws yuav muaj txiaj ntsig los ntxuav lub EGR system, lossis tsawg kawg ntawm qhov ntsuas kub. Nco ntsoov tias cov cim teeb tsa hauv lub tshuab tso pa tuaj yeem hnov ​​pinched thaum sim tshem tawm.

Nco ntsoov tias cov ntsuas no raug rau qhov hloov pauv ntawm qhov kub thiab txias, yog li siv cua sov me ntsis siv lub tswb hluav taws xob OAC (tsis yog rau tus tso) tuaj yeem pab ua kom lub zog tsis muaj zog. Tom qab tshem lub ntsuas cua, siv lub tshuab nqus tsev carburetor lossis cov khoom sib xws los ua kom cov dej so zoo. Siv cov xaim txhuam kom tshem cov quav ntau dhau los ntawm thaj chaw sib sau ua ke. Thaum rov txhim kho lub ntsuas kom huv, nco ntsoov thov tiv thaiv kev txeeb cov khoom sib xyaw rau cov xov kom tiv thaiv kev thab plaub.

Nco tseg. Qhov kawg uas koj xav ua ntawm no yog rhuav tshem lub sensor hauv lub manifold / exhaust manifold. Qhov no tuaj yeem yog qhov yuam kev kim, yog li siv koj lub sijhawm thaum tawg lub sensor.

Kauj ruam yooj yim # 3

Txheeb xyuas qhov tseeb ntawm lub ntsuas cua los ntawm kev ntsuas qhov ntsuas hluav taws xob tiag tiag piv rau cov chaw tsim khoom xav tau qhov tseem ceeb. Ua qhov no nrog lub ntsuas cua thiab ua raws cov txheej txheem kev pov thawj tiv toj.
