P0473 Cov tswv yim siab ntawm lub tshuab tso pa siab

P0473 – OBD-II Teeb meem Code Technical Description

Tus lej P0473 qhia tau hais tias lub tso pa tawm lub siab sensor muaj lub teeb liab tawm siab.

Qhov txhaum cai txhais li cas P0473?

Teeb meem code P0473 qhia lub siab tso pa roj siab sensor input teeb liab. Qhov no txhais tau hais tias lub cav tswj qhov system tau kuaj pom qhov tsis zoo ntawm qhov hluav taws xob siab nyob rau hauv cov pa roj siab sensor Circuit Court. Cov cai no feem ntau cuam tshuam nrog cov tsheb nruab nrog diesel lossis turbocharged xyaw. Cov lej yuam kev kuj tseem tuaj yeem tshwm sim nrog rau cov lej no. P0471 и P0472.

Tej zaum ua rau

Qee qhov laj thawj rau P0473 teeb meem code:

• Pa pa siab sensor ua haujlwm tsis zoo: Qhov feem ntau thiab pom tseeb qhov teeb meem ntawm qhov teeb meem yog qhov ua haujlwm tsis zoo ntawm cov pa roj cua siab sensor nws tus kheej. Qhov no tuaj yeem tshwm sim los ntawm kev hnav, kev puas tsuaj, lossis kev ua haujlwm tsis zoo ntawm lub sensor.
• Teeb meem hluav taws xob: Qhib, corrosion, los yog puas nyob rau hauv hluav taws xob Circuit Court txuas lub tso pa roj siab sensor mus rau lub engine tswj module (PCM) tej zaum yuav ua rau cov nyeem tsis raug los yog tsis muaj teeb liab los ntawm lub sensor.
• Teeb meem nrog lub tso pa tawm: Kev tso pa tsis txaus lossis tsis raug, tshwm sim los ntawm kev thaiv lossis xau hauv cov pa tawm, piv txwv li, kuj tuaj yeem ua rau tus lej P0473 tshwm.
• Turbo teeb meem: Ntawm qee lub tsheb turbocharged, muaj cov khoom siv hluav taws xob uas tuaj yeem ua rau P0473 code yog tias lawv ua haujlwm tsis raug lossis tsis ua haujlwm zoo.
• PCM software teeb meem: Qee lub sij hawm tsis raug lub cav tswj module (PCM) software lossis ua haujlwm tsis zoo tuaj yeem ua rau cov pa hluav taws xob raug kuaj pom tsis raug thiab ua rau P0473 code tshwm.
• Mechanical puas: Mechanical puas los yog deformation nyob rau hauv lub tso pa system, xws li xau los yog cov kav dej puas, kuj tuaj yeem ua rau P0473 code.

Cov tsos mob ntawm tus lej yuam kev yog dab tsi? P0473?

Cov tsos mob rau DTC P0473 yuav txawv nyob ntawm seb lub tsheb tshwj xeeb thiab lwm yam:

• Ntau cov pa luam yeeb dub los ntawm cov pa tso pa tawm: Yog tias qhov teeb meem yog vim muaj qhov tso pa tawm tsis txaus, qhov no yuav ua rau muaj cov pa luam yeeb dub ntau ntxiv los ntawm qhov tso pa tawm.
• Poob lub cav fais fab: Kev ua haujlwm tsis zoo nyob rau hauv qhov tso pa tawm tuaj yeem ua rau txo qis lub zog ntawm lub cav lossis kev ua haujlwm nrawm dua.
• Kev ua haujlwm tsis ruaj khov: Yog tias lub tshuab tso pa ua haujlwm tsis zoo, lub cav tsis muaj zog tuaj yeem tshwm sim, suav nrog kev ua haujlwm tsis sib xws lossis txawm tias lub tog raj kheej kaw.
• Cov teeb meem tshwm sim ntawm qhov ntsuas vaj huam sib luag: Yog tias pom muaj teeb meem nrog cov pa tso pa tawm, lub cav tswj lub cav yuav qhib lub teeb "Check Engine" ntawm lub ntsuas vaj huam sib luag thiab khaws P0473 yuam kev code hauv PCM nco.
• Lub suab txawv txawv: Yog hais tias lub tso pa tawm puas lawm los yog xau, lub suab txawv txawv xws li lub suab nrov nrov lossis lub suab nrov yuav tshwm sim, tshwj xeeb tshaj yog thaum lub cav ceev nce.

Yuav ua li cas kuaj tau tus lej txhaum P0473?

Txhawm rau kuaj xyuas DTC P0473, koj tuaj yeem ua cov hauv qab no:

1. Tshawb xyuas qhov kev sib txuas ntawm cov pa tso pa tawm lub siab sensor: Txheeb xyuas cov kev sib txuas rau lub tshuab nqus cua siab thiab xyuas kom cov kev sib txuas ruaj ntseg thiab tsis puas.
2. Tshawb xyuas kev sib txuas hluav taws xob thiab xaim hluav taws xob: Txheeb xyuas qhov xwm txheej ntawm cov khoom siv hluav taws xob, kev sib txuas thiab cov khoom sib txuas ua rau cov pa hluav taws xob siab sensor. Xyuas kom lawv tsis pom kev puas tsuaj, corrosion los yog tawg.
