P0372 Kev daws teeb meem siab teeb tsa lub sijhawm tswj "A" - ob peb lub pulses

P0372 – OBD-II Teeb meem Code Technical Description

Teeb meem code P0372 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 P0372?

Teeb meem code P0372 qhia tias lub cav tswj module (ECM) lossis kis tau tus mob tswj module (PCM) tau kuaj pom muaj teeb meem nrog lub tsheb qhov kev daws teeb meem siab "A" siv lub teeb liab hauv lub tsheb lub sijhawm. Cov teeb liab no feem ntau yog siv los synchronize cov roj txhaj tshuaj thiab saib xyuas cov pulses kuaj pom ntawm lub sensor disk mounted ntawm lub twj tso kua mis roj. Hauv cov ntsiab lus yooj yim, teeb meem code P0372 qhia tias tus naj npawb ntawm cov teeb liab sensor pulses tsis yog tus lej xav tau.

Tej zaum ua rau

Teeb meem code P0372 tuaj yeem tshwm sim los ntawm ntau yam laj thawj:

• 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, nws yuav ua rau P0372 code.
