P0804 – OBD-II Teeb meem Code Technical Description

Teeb meem code P0804 qhia tias muaj kev ua haujlwm tsis zoo hauv 1-4 upshift ceeb toom teeb (hla iav) tswj Circuit Court.

Qhov txhaum cai txhais li cas P0804?

Teeb meem code P0804 qhia tias muaj teeb meem hauv lub tsheb hloov lub teeb tswj qhov system (qee zaus hu ua hloov lub teeb tswj qhov system). Cov cai no qhia tau hais tias lub powertrain control module (PCM) tau kuaj pom muaj kev ua haujlwm tsis zoo hauv cov hluav taws xob hluav taws xob uas tswj tau lub teeb upshift. Yog li ntawd, tus neeg tsav tsheb yuav ntsib teeb meem hloov lub zog los yog pom tias lub teeb ua haujlwm tsis raug. Thaum pom qhov teeb meem no, PCM khaws P0804 code thiab qhib lub teeb pom kev tsis zoo (MIL) kom ceeb toom tus neeg tsav tsheb ntawm qhov teeb meem.

Tej zaum ua rau

Teeb meem code P0804 tuaj yeem tshwm sim los ntawm ntau yam laj thawj:

• Hluav taws xob Circuit Court tsis zoo: Teeb meem ntawm cov xaim, cov khoom sib txuas, lossis cov kev sib txuas uas tswj lub teeb hloov tuaj yeem ua rau cov cai no tshwm sim.
• Lub iav hloov pauv tsis zoo: Yog tias lub iav hloov pauv tsis ua haujlwm zoo lossis raug kho, nws tuaj yeem ua rau P0804 code.
• Powertrain Control Module (PCM) Cov teeb meem: Cov teeb meem tsis zoo hauv Powertrain Control Module nws tus kheej tuaj yeem ua rau lub teeb hloov pauv hloov pauv tsis raug, ua rau P0804.
• Cov teeb meem ntawm Cav Tswj Module (ECM): Txij li ntau TCMs tau koom ua ke nrog ECM hauv tib PCM, teeb meem nrog ECM kuj tuaj yeem ua rau P0804 code.
• Kev cuam tshuam hluav taws xob lossis kev cuam tshuam hauv lub tsheb hluav taws xob: Cov teeb liab hluav taws xob tsis tswj lossis teeb meem hluav taws xob tuaj yeem ua rau lub tshuab hluav taws xob tswj tsis ua haujlwm thiab ua rau muaj teeb meem code P0804.

Txhawm rau txheeb xyuas qhov ua tau kom raug, nws yog qhov yuav tsum tau kuaj xyuas qhov kis tau tus mob siv cov cuab yeej tshwj xeeb lossis hu rau tus kws kho tsheb tsim nyog.

Cov tsos mob ntawm tus lej yuam kev yog dab tsi? P0804?

Cov tsos mob rau P0804 teeb meem code yuav txawv nyob ntawm seb qhov teeb meem tshwj xeeb nrog lub teeb tswj kev hloov pauv, tab sis qee cov tsos mob muaj xws li:

• Hloov Teebmeem: Tus neeg tsav tsheb yuav ntsib teeb meem lossis tsis muaj peev xwm hloov lub zog, tshwj xeeb tshaj yog thaum nce.
• Kev Ua Haujlwm Tsis raug: Lub iav hloov lub teeb ntawm lub ntsuas vaj huam sib luag yuav tsis ua haujlwm kom raug lossis tso saib cov ntaub ntawv tsis raug txog cov iav tam sim no.
