P0474 Cov pa pa tsis ruaj tsis khov siab sensor teeb liab Circuit Court

P0474 – OBD-II Teeb meem Code Technical Description

Teeb meem code P0474 qhia tias PCM tau kuaj pom qhov tsis sib xws ntawm cov pa roj cua siab sensor Circuit Court teeb liab.

Qhov txhaum cai txhais li cas P0474?

Teeb meem code P0474 qhia txog ib qho teeb meem tsis sib xws hauv cov pa roj cua siab sensor Circuit Court. Cov pa roj cua siab feem ntau yog saib xyuas hauv cov tsheb nrog diesel thiab turbocharged xyaw. Lub tso pa tawm lub siab sensor muab qhov ntsuas hluav taws xob rau ECM (lub cav tswj module) los txiav txim siab qib siab tam sim no. Yog tias tus nqi siab tiag tiag txawv ntawm tus nqi teev hauv cov chaw tsim khoom tshwj xeeb, P0474 code yuav tshwm sim.

Tej zaum ua rau

Qee qhov laj thawj rau P0474 teeb meem code:

• Pa pa siab sensor ua haujlwm tsis zoo: Cov teeb liab tsis zoo los ntawm qhov tso pa tawm lub siab sensor tuaj yeem tshwm sim los ntawm kev hnav, kev puas tsuaj lossis ua haujlwm tsis zoo.
• Teeb meem hluav taws xob: Qhib, corrosion los yog kev puas tsuaj nyob rau hauv hluav taws xob Circuit Court txuas cov pa roj siab sensor rau PCM (engine control module) tuaj yeem ua rau muaj teeb meem tsis sib haum xeeb.
• Teeb meem nrog PCM: Kev ua haujlwm tsis zoo lossis software yuam kev hauv PCM tuaj yeem ua rau P0474.
• Mechanical puas: Kev puas tsuaj los yog deformation nyob rau hauv lub tso pa tawm, xws li xau, blockages los yog teeb meem nrog lub tso pa manifold, tej zaum yuav ua rau instability nyob rau hauv lub tso pa roj siab thiab lus yuam kev.
• Turbo teeb meem: Rau cov tsheb turbocharged, teeb meem nrog lub turbo lossis boost tswj valve tuaj yeem ua rau lub siab tsis ruaj khov hauv cov pa tawm.

Cov no tsuas yog cov laj thawj dav dav thiab nws raug pom zoo kom kuaj xyuas ntxiv txhawm rau txheeb xyuas qhov teeb meem.

Cov tsos mob ntawm tus lej yuam kev yog dab tsi? P0474?

Cov tsos mob rau cov teeb meem code P0474 tuaj yeem sib txawv nyob ntawm seb qhov laj thawj tshwj xeeb thiab kev tsim tsheb, qee cov tsos mob uas yuav tshwm sim yog:

• Kos Lub Cav Teeb Illuminates: Ib qho ntawm thawj cov cim qhia ntawm qhov teeb meem yuav yog qhov ua kom lub teeb pom kev ntawm lub tshuab hluav taws xob ntawm koj lub dashboard.
• Poob lub cav fais fab: Ib qho tsis ruaj tsis khov pa roj siab sensor teeb liab yuav ua rau lub cav tsis muaj zog lossis ua haujlwm tsis zoo.
• Tsis ruaj tsis khov: Yog tias cov pa tso pa tawm tsis ruaj khov txaus, qhov tsis ua haujlwm ntawm lub cav yuav raug cuam tshuam.
• Kev siv roj ntau ntxiv: Cov pa tsis ruaj khov siab yuav ua rau muaj roj ntau ntxiv.
• Turbocharged teeb meem (rau cov tsheb turbocharged): Nyob rau hauv cov ntaub ntawv ntawm turbocharged tsheb, boost instability tuaj yeem tshwm sim, uas tuaj yeem ua rau poob ntawm lub zog thiab lwm yam teeb meem ntawm lub cav.

Yog tias koj xav tias muaj teeb meem nrog koj lub qhov tso pa tawm los yog pom cov tsos mob saum toj no, nws raug nquahu kom koj coj nws mus rau tus kws kho tsheb tsim nyog rau kev kuaj mob thiab kho.

Yuav ua li cas kuaj tau tus lej txhaum P0474?

Rau DTC P0474, ua raws li cov kauj ruam no:

• Tshawb xyuas kev sib txuas thiab cov xov hlau: Txheeb xyuas tag nrho cov kev sib txuas hluav taws xob thiab cov xov hlau txuas cov pa roj cua siab sensor rau lub cav tswj module (PCM) lossis lub cav. Ua tib zoo saib xyuas kev puas tsuaj, corrosion lossis tawg.
• Tshawb xyuas qhov tso pa tawm lub siab sensor: Siv lub tshuab ntsuas ntau los kuaj xyuas qhov ua haujlwm ntawm cov pa roj cua siab sensor.
