P0371 – OBD-II Teeb meem Code Technical Description

Teeb meem code P0371 yog qhov teeb meem dav dav uas qhia tias Lub Cav Tswj Xyuas Module (ECM) tau kuaj pom muaj teeb meem nrog lub tsheb lub sijhawm ua haujlwm siab daws teeb meem "A" siv teeb liab.

Qhov txhaum cai txhais li cas P0371?

Teeb meem code P0371 qhia tias lub tsheb lub tshuab hluav taws xob tswj tau kuaj pom qhov kev hloov pauv ntawm lub tshuab hluav taws xob lub sijhawm ua haujlwm siab, tshwj xeeb tshaj yog cov pulses ntau dhau. Qhov no tuaj yeem tshwm sim los ntawm ntau yam teeb meem, xws li lub cev muaj zog crankshaft txoj hauj lwm sensor, teeb meem thaiv, lossis teeb meem hluav taws xob.

Tej zaum ua rau

Teeb meem code P0371 tuaj yeem tshwm sim los ntawm ntau yam laj thawj, suav nrog:

• Tsis zoo crankshaft txoj hauj lwm (CKP) sensor: Yog tias CKP sensor tsis ua haujlwm zoo lossis ua tsis tiav, nws yuav ua rau P0371 code.
• Teeb meem nrog kev xaim lossis hluav taws xob sib txuas: Qhib, luv Circuit Court lossis lwm yam teeb meem nrog kev xaim lossis hluav taws xob sib txuas ntawm CKP sensor thiab ECU tuaj yeem ua rau qhov yuam kev.
• Malfunctions nyob rau hauv lub ignition system: Kev ua haujlwm tsis zoo hauv lub tshuab hluav taws xob, xws li lub tshuab hluav taws xob tsis zoo, cov hluav taws xob, lossis cov xov hlau, tuaj yeem ua rau CKP sensor ua haujlwm tsis zoo thiab ua rau muaj teeb meem code P0371.
• Teeb meem nrog lub crankshaft iav los yog hniav: Yog hais tias lub crankshaft iav los yog cov hniav puas los yog qias neeg, nws yuav ua rau lub CKP sensor nyeem cov teeb liab tsis raug thiab ua rau muaj kev ua yuam kev.
• Teeb meem nrog ECU (electronic control unit): Kev ua haujlwm tsis raug lossis kev puas tsuaj rau ECU nws tus kheej kuj tuaj yeem ua rau P0371.

Txhawm rau txiav txim siab qhov ua rau muaj qhov yuam kev, nws raug nquahu kom ua qhov kev kuaj mob ntxaws ntawm lub tsheb siv cov cuab yeej tsim nyog thiab, yog tias tsim nyog, hloov lossis kho cov khoom cuam tshuam.

Cov tsos mob ntawm tus lej yuam kev yog dab tsi? P0371?

Cov tsos mob rau DTC P0371 yuav txawv nyob ntawm seb qhov ua rau ntawm txoj cai thiab cov yam ntxwv ntawm lub tsheb. Qee cov tsos mob uas tshwm sim nrog qhov yuam kev no yog:

• Nyuaj pib lub cav: Ib qho tsis xws luag crankshaft txoj hauj lwm sensor tuaj yeem ua rau muaj teeb meem pib lub cav lossis txawm tias tsis ua tiav lub cav pib.
• Rough engine ua haujlwm: Kev nyeem ntawv crankshaft tsis raug tuaj yeem ua rau lub cav khiav tsis zoo, tsis ruaj khov ceev, lossis txawm tias poob lub zog.
• Ignition tsis zoo: Yog hais tias lub crankshaft txoj hauj lwm sensor tsis ua hauj lwm zoo, nws yuav ua rau ib tug misfire, uas yuav manifest nws tus kheej nyob rau hauv lub rattling los yog jerking engine.
