P0377 Kev daws teeb meem siab B teeb liab theem tswj - tsawg dhau pulses

P0377 – OBD-II Teeb meem Code Technical Description

Teeb meem code P0377 yog ib qho kev cai dav dav uas qhia tias PCM tau kuaj pom muaj teeb meem nrog lub tsheb lub sijhawm ua haujlwm siab daws teeb meem siv "B" teeb liab.

Qhov txhaum cai txhais li cas P0377?

Teeb meem code P0377 qhia tias muaj teeb meem nrog lub tsheb lub sijhawm ua haujlwm siab daws teeb meem siv "B" teeb liab. Qhov no txhais tau hais tias lub cav tswj module (PCM) tau kuaj pom qhov txawv txav ntawm lub sijhawm teeb tsa siab (ntau dhau ob peb pulses) uas xa los ntawm optical sensor mounted ntawm lub twj tso kua mis roj. Teeb meem code P0377 qhia tias tus naj npawb ntawm cov pulses kuaj pom los ntawm lub sensor tsis sib xws rau cov pulses xav tau rau kev ua haujlwm ntawm lub cav lub sijhawm.

Tej zaum ua rau

Qee qhov laj thawj rau P0377 teeb meem code:

• Optical sensor malfunction: Cov khoom siv kho qhov muag uas xa cov teeb liab daws teeb meem tuaj yeem raug puas los yog ua tsis tiav vim hnav, corrosion, lossis lwm yam teeb meem.
• Teeb meem nrog kev xaim thiab cov khoom sib txuas: Kev tawg, kev xeb, lossis kev sib txuas tsis zoo hauv cov xaim lossis cov khoom sib txuas ntawm cov khoom siv kho qhov muag thiab lub cav tswj module (PCM) tuaj yeem ua rau P0377.
• Mechanical teeb meem nrog lub sensor disk: Lub sensor disk uas lub teeb liab nyeem yuav raug puas ntsoog, misaligned, los yog qias neeg, tiv thaiv lub teeb liab los ntawm kev nyeem kom raug.
• Teeb meem nrog lub cav tswj module (PCM): Kev ua haujlwm tsis zoo lossis ua yuam kev hauv kev ua haujlwm ntawm PCM nws tus kheej tuaj yeem ua rau P0377 code.
• Teeb meem nrog cov roj txhaj tshuaj: Qhov tsis sib xws ntawm cov pulses ntawm lub sensor dial tuaj yeem tshwm sim los ntawm cov teeb meem nrog cov roj txhaj tshuaj, xws li cov twj tso kua mis tsis raug lossis cov twj tso kua mis.
• Lwm yam teeb meem hluav taws xob lossis tshuab: Qee zaum, lwm yam teeb meem, xws li teeb meem ntawm lub tsheb lub tshuab hluav taws xob lossis teeb meem ntawm kev siv tshuab, tuaj yeem ua rau P0377 code.

Txhawm rau txiav txim siab qhov ua yuam kev, nws raug nquahu kom ua qhov kev kuaj mob kom ntxaws siv cov cuab yeej kuaj mob lossis hu rau tus kws kho tsheb tsim nyog.

Cov tsos mob ntawm tus lej yuam kev yog dab tsi? P0377?

Cov tsos mob rau DTC P0377 tuaj yeem sib txawv nyob ntawm qhov xwm txheej tshwj xeeb thiab qhov xwm txheej ntawm qhov teeb meem, qee cov tsos mob tshwm sim yog:

• Lub teeb Check Engine los rau: Ib qho ntawm feem ntau cov cim qhia ntawm ib qho teeb meem yog lub Check Engine teeb ntawm koj lub tsheb dashboard tuaj.
