Txoj cai txhaum loj npaum li cas? P1002?

Lub Transmission Control Module (TCM) siv lub sijhawm tseem ceeb los ua lwm yam kev kuaj mob. Txhawm rau kom ntseeg tau qhov tseeb ntawm kev ua kom muaj kev kuaj mob, TCM kuaj xyuas tias lub tshuab hluav taws xob tawm lub sijhawm ua haujlwm raug. Lub ignition off timer tus nqi yog muab cia rau hauv lub cabin compartment node (CCN). CCN xa cov lus hloov hluav taws xob lub sijhawm mus rau Totally Integrated Power Module (TIPM). TIPM xa lub sijhawm no los ntawm lub npav CAN.

Lub TCM tau txais cov lus thiab sib piv cov ignition OFF timer tus nqi nrog lub cav coolant kub thaum lub ignition yog OFF thiab lub cav coolant pib kub lus. Yog hais tias lub sij hawm ignition txiav tsawg dua tus nqi ntsuas raws li lub cav coolant ignition txiav kub thiab lub cav coolant crank kub, ib tug diagnostic teeb meem code (DTC) yuav teem.

Kev kho dab tsi yuav pab tshem tawm cov cai? P1002?

Cov lej yuam kev, suav nrog P1002, qhia txog teeb meem nrog lub tsheb lub cev. Kev daws tus lej P1002 yuav xav tau kev kuaj mob thiab hais txog qhov laj thawj. Nov yog qee cov kauj ruam kho tau:

  1. Xyuas thiab hloov sensors: Code P1002 qee zaum cuam tshuam nrog cov teeb meem nrog cov sensors xws li huab cua huab cua txaus (MAF) sensors lossis manifold cua siab sensors. Ua cov kev kuaj mob thiab, yog tias tsim nyog, hloov cov sensors tsis raug.
  2. Xyuas thiab ntxuav lub roj system: Teeb meem nrog cov roj system tuaj yeem ua rau muaj teeb meem. Tshawb xyuas lub twj tso kua mis roj, roj lim thiab cov tshuaj txhaj tshuaj rau cov teeb meem thiab, yog tias tsim nyog, ntxuav lossis hloov lawv.
  3. Xyuas qhov system intake: Huab cua xau los yog teeb meem nrog kev noj haus tuaj yeem ua rau P1002 code. Tshawb xyuas lub kaw lus rau kev xau thiab xyuas kom muaj kev sib txuas ruaj ntseg.
  4. Xyuas lub ignition system: Teeb meem nrog lub ignition system, xws li faulty spark plugs los yog ignition coils, yuav ua rau yuam kev. Tshuaj ntsuam xyuas thiab hloov cov faulty Cheebtsam.
  5. Tshawb xyuas lub ignition hloov lub sij hawm: Xyuas kom lub ignition off timer ua haujlwm kom raug. Yog tias tsim nyog, hloov lub timer faulty.
  6. Tshawb xyuas kev sib txuas hluav taws xob: Kev sib txuas hluav taws xob tsis raug yuav ua rau muaj teeb meem. Tshawb xyuas cov hlua thiab cov khoom sib txuas rau kev puas tsuaj lossis corrosion.
  7. Calibration thiab programming: Qee cov khoom, xws li sensors, yuav xav tau calibration lossis programming tom qab hloov.

Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov lus pom zoo no tau muab rau hauv cov ntsiab lus dav dav thiab cov kev ua tshwj xeeb yuav nyob ntawm koj lub tsheb tsim thiab qauv, nrog rau cov ntaub ntawv kuaj mob ntxiv. Yog tias koj tsis muaj kev paub txog kev kho tus kheej, nws raug nquahu kom hu rau tus kws tshaj lij kev pabcuam tsheb rau kev kuaj mob kom raug thiab tshem tawm qhov teeb meem.
