P0375 High Resolution B Signal Phase Timing Malfunction

P0375 – OBD-II Teeb meem Code Technical Description

Teeb meem code P0375 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 P0375?

Teeb meem code P0375 qhia txog teeb meem nrog lub siab daws teeb meem crankshaft siv (CKP) sensor teeb liab. Qhov no txhais tau hais tias lub tsheb lub cav tswj module (ECM) lossis kis tau tus mob tswj module (PCM) tau kuaj pom qhov txawv txav ntawm lub teeb liab uas ib txwm siv los ua kom zoo rau lub cav thiab kev sib kis.

Tej zaum ua rau

Muaj ntau qhov laj thawj uas tuaj yeem ua rau P0374 teeb meem code:

• Faulty crankshaft txoj hauj lwm (CKP) sensor: Lub CKP sensor yog lub luag hauj lwm rau kev xa cov crankshaft txoj hauj lwm teeb liab mus rau lub cav tswj system. Yog hais tias lub sensor yog faulty los yog muab lub teeb liab tsis raug, nws tuaj yeem ua rau P0374.
• Teeb meem nrog kev xaim thiab kev sib txuas: Qhib, luv luv, lossis lwm yam teeb meem nrog cov xaim, kev sib txuas, lossis cov khoom sib txuas ntawm CKP sensor thiab lub cav tswj module tuaj yeem ua rau P0374.
• Crankshaft sensor disc: Kev puas tsuaj lossis hnav rau lub crankshaft sensor disc yuav ua rau lub teeb liab tsis tau nyeem kom raug, ua rau P0374.
• Teeb meem nrog lub cav tswj module (ECM) lossis kis tau tus mob tswj module (PCM): Kev ua haujlwm tsis zoo hauv ECM lossis PCM, uas yog lub luag haujlwm rau kev ua cov cim qhia los ntawm CKP sensor thiab synchronizing cov haujlwm ntawm lub cav thiab tsis siv neeg kis, tuaj yeem ua rau P0374 code.
• Teeb meem nrog lub ignition system los yog roj txhaj system: Kev ua haujlwm tsis zoo ntawm lwm cov khoom ntawm lub tshuab hluav taws xob lossis cov roj txhaj tshuaj, xws li ignition coils, spark plugs lossis injectors, tuaj yeem ua rau CKP sensor malfunction thiab ua rau P0374 code.
• Teeb meem nrog lub crankshaft iav los yog hniav: Yog hais tias lub crankshaft iav los yog cov hniav puas lawm los yog hnav, nws yuav cuam tshuam lub teeb liab los ntawm CKP sensor thiab ua rau P0374.

Cov no tsuas yog qee qhov piv txwv ntawm qhov ua rau, thiab txhawm rau txiav txim siab qhov ua rau ntawm P0374 code, nws raug nquahu kom koj ua cov ncauj lus kom ntxaws ntawm lub tsheb uas siv cov cuab yeej kuaj mob lossis hu rau tus kws kho tsheb tus kws tshaj lij.

Cov tsos mob ntawm tus lej yuam kev yog dab tsi? P0375?

Cov tsos mob rau DTC P0375 yuav suav nrog cov hauv qab no:

• Teeb meem nrog pib lub cav: Rough engine pib los yog ua tiav tsis kam pib tej zaum yuav yog ib qho ntawm thawj cov cim qhia ntawm ib qho teeb meem nrog lub crankshaft txoj hauj lwm (CKP) teeb liab.
• Rough engine ua haujlwm: Kev soj ntsuam kev ua haujlwm tsis zoo ntawm lub cav, xws li rattling, jerking, lossis ntxhib idling, kuj tseem qhia tau tias muaj teeb meem nrog CKP teeb liab.
• Lub zog tsis muaj zog: Yog tias CKP teeb liab tsis raug, lub cav yuav poob lub zog, ua rau lub tsheb tsis zoo tag nrho.
• Kev siv roj ntau ntxiv: Kev ua haujlwm tsis raug ntawm CKP teeb liab yuav ua rau tsis muaj roj combustion, uas yuav ua rau muaj roj ntau ntxiv.
• Kos qhov taw qhia cav: Lub tshuab kuaj xyuas lub teeb tig rau ntawm koj lub tsheb dashboard yog ib qho ntawm cov tsos mob tshwm sim ntawm P0375 code. Qhov ntsuas no ceeb toom tus neeg tsav tsheb ntawm cov teeb meem tshwm sim nrog lub cav ua haujlwm.
• Iav hloov teeb meem (rau kev sib kis tsis siv neeg): Yog hais tias lub tsheb yog nruab nrog ib tug tsis siv neeg kis tau tus mob, yuam kev nrog CKP teeb liab yuav ua rau muaj teeb meem nrog lub iav hloov los yog tam sim ntawd txav.

Cov tsos mob no yuav tshwm sim rau qhov sib txawv thiab nyob ntawm qhov teeb meem tshwj xeeb. Yog tias koj ntsib cov tsos mob no, nws raug nquahu kom koj tam sim ntawd hu rau tus kws kho tsheb kws kho mob kom kuaj xyuas thiab kho qhov teeb meem.

Yuav ua li cas kuaj tau tus lej txhaum P0375?

Cov kauj ruam hauv qab no raug pom zoo los kuaj xyuas DTC P0375:

1. Kev txheeb xyuas cov lej yuam kev: Siv lub tshuab kuaj kab mob los nyeem cov lej yuam kev hauv kev tswj hwm lub cav. Txheeb xyuas tias P0375 code muaj tseeb nyob hauv ECM (lossis PCM) nco thiab xyuas kom meej tias qhov no yog qhov teeb meem hauv paus.
