P0800 Transfer Case Control System (MIL Interrogation) - Circuit Court malfunction

P0800 – OBD-II Teeb meem Code Technical Description

Teeb meem code P0800 qhia txog qhov yuam kev hloov chaw tswj qhov system Circuit Court (MIL nug)

Qhov txhaum cai txhais li cas P0800?

Teeb meem code P0800 qhia tias muaj teeb meem nrog cov ntaub ntawv hloov chaw tswj qhov system Circuit Court. Qhov no txhais tau hais tias lub powertrain tswj module (PCM) tau txais ib qho teeb meem txhaum cai nyob rau hauv lub hloov rooj plaub tswj system, uas yuav tsum tau ua kom lub malfunction qhia teeb (MIL).

PCM siv cov ntaub ntawv los ntawm ntau lub cav, kis tau tus mob thiab hloov cov ntaub ntawv sensors los txhim kho qhov tsis siv neeg kis tau tus mob hloov lub tswv yim. Cov ntaub ntawv hloov tsheb yog lub luag haujlwm rau kev hloov lub zog ntawm lub cav mus rau pem hauv ntej thiab nram qab qhov sib txawv, raws li.

Tej zaum ua rau

Tej yam ua tau rau DTC P0800 yuav suav nrog cov hauv qab no:

• Malfunction nyob rau hauv cov ntaub ntawv hloov tsheb: Teeb meem ntawm cov ntaub ntawv hloov chaw nws tus kheej, xws li kev puas tsuaj rau lub tshuab hloov pauv lossis kev ua haujlwm tsis raug ntawm lub tshuab xauv, tuaj yeem ua rau cov cai no tshwm sim.
• Teeb meem nrog sensors: Kev ua haujlwm tsis zoo ntawm cov sensors lub luag haujlwm rau kev sib txuas lus hloov pauv cov xwm txheej mus rau PCM, xws li txoj haujlwm sensor lossis ceev sensor, tuaj yeem ua rau cov cai no tshwm sim.
• Teeb meem hluav taws xob: Kev sib txuas tsis zoo, tawg, lossis luv luv hauv cov hluav taws xob hluav taws xob cuam tshuam nrog kev hloov pauv rooj plaub tuaj yeem ua rau muaj teeb meem code P0800.
• Software teeb meem: Kev ua yuam kev lossis yuam kev hauv PCM software lub luag haujlwm rau kev tswj cov ntaub ntawv hloov chaw yuav ua rau cov cai no tshwm sim.
• Teeb meem nrog iav hloov mechanisms: Cov teeb meem lossis kev hnav hauv cov ntaub ntawv hloov pauv hloov pauv tuaj yeem ua rau kev ua haujlwm tsis raug thiab ua rau DTC P0800.

Cov laj thawj no xav tau kev kuaj mob ntxiv kom raug txiav txim siab lub hauv paus ntawm qhov teeb meem.

Cov tsos mob ntawm tus lej yuam kev yog dab tsi? P0800?

Cov tsos mob tshwm sim rau DTC P0800:

• Iav hloov teeb meem: Tus neeg tsav tsheb yuav pom tias kev hloov lub iav tsis tshwm sim kom raug lossis qeeb.
• Cov suab tsis zoo los yog kev vibrations: Tej zaum yuav muaj lub suab txawv txawv lossis kev vibrations thaum lub tsheb tau tsav vim kev ua haujlwm ntawm cov ntaub ntawv hloov chaw.
• Gear indicator malfunction: Lub iav qhov taw qhia ntawm lub ntsuas vaj huam sib luag yuav qhia cov ntaub ntawv tsis raug lossis flash, qhia txog teeb meem ntawm rooj plaub hloov.
• Malfunction indicator light (MIL) tshwm: Yog tias PCM pom ib qho teeb meem hauv kev tswj cov ntaub ntawv hloov chaw, qhov taw qhia ua haujlwm tsis zoo ntawm lub ntsuas vaj huam sib luag yuav raug qhib.
• Malfunctioning tus cwj pwm ntawm lub tsheb nyob rau hauv ntau yam mob: Lub tsheb yuav pom tus cwj pwm txawv txawv thaum tsav tsheb hauv ntau hom (piv txwv li, rau pem hauv ntej, rov qab, plaub-log tsav), uas tej zaum yuav yog vim muaj teeb meem nyob rau hauv cov ntaub ntawv hloov chaw.
• Kev siv roj ntau ntxiv: Kev ua haujlwm tsis raug ntawm cov ntaub ntawv hloov pauv tuaj yeem ua rau muaj kev siv roj ntau ntxiv vim kev hloov pauv hloov tsis zoo thiab tsis muaj zog hloov pauv.

Yog tias koj pom ib qho ntawm cov tsos mob no, nws raug nquahu kom koj hu rau tus kws kho mob uas tsim nyog rau kev kuaj mob thiab kho.

Yuav ua li cas kuaj tau tus lej txhaum P0800?

Cov kauj ruam hauv qab no raug pom zoo los kuaj xyuas DTC P0800:
