P0468 Purge Flow Sensor Circuit Court siab

P0468 – OBD-II Teeb meem Code Technical Description

Teeb meem code P0468 qhia tau hais tias muaj teeb liab tawm tswv yim siab los ntawm kev tshem tawm cua ntws sensor. 

Qhov txhaum cai txhais li cas P0468?

Teeb meem code P0468 qhia tau hais tias muaj teeb liab tawm tswv yim siab los ntawm kev tshem tawm cua ntws sensor. Qhov no yuav qhia tau tias muaj kev ua haujlwm tsis zoo ntawm cov evaporative emission system, feem ntau yog vim muaj qhov qhib hluav taws xob nruab nrab ntawm lub tshuab nqus cua ntws thiab PCM (lub cav tswj module). Cov lej teeb meem P0440 thiab P0442 kuj tseem tuaj yeem tshwm sim nrog cov cai no, qhia txog cov teeb meem ntawm lub hau roj, thiab cov lej P0443 txog P0449, qhia txog teeb meem nrog cov evaporative emission tswj purge solenoid valve.

Tej zaum ua rau

Qee qhov laj thawj rau P0468 teeb meem code:

• Qhib Circuit Court los yog corrosion nyob rau hauv hluav taws xob Circuit Court: Teeb meem nrog cov xov hlau, kev sib txuas lossis cov khoom sib txuas ntawm lub tshuab nqus cua ntws sensor thiab PCM tuaj yeem ua rau muaj teeb meem siab.
• Purge air flow sensor malfunction: Lub sensor nws tus kheej tej zaum yuav puas los yog malfunctioning, ua rau ib tug txawv txav siab teeb liab.
• Kev puas tsuaj lossis ua haujlwm tsis zoo ntawm lwm cov evaporative emission system Cheebtsam: Qhov no suav nrog lub hau roj, roj tank, tshem tawm valve, roj vapor hoses, lub tshuab nqus tsev, roj siab thiab ntws sensors, thiab cov xov hluav taws xob thiab cov khoom sib txuas.
• Kev ua haujlwm tsis zoo ntawm PCM: Nyob rau hauv tsawg zaus, ib tug malfunction nyob rau hauv lub engine tswj module yuav ua rau lub teeb liab los ntawm lub purge air flow sensor yuav tsum tau txhais tsis raug.

Cov laj thawj no yuav yog hauv qab thiab xav tau kev kuaj mob ntxiv kom raug txheeb xyuas thiab tshem tawm qhov teeb meem.

Cov tsos mob ntawm tus lej yuam kev yog dab tsi? P0468?

Cov tsos mob rau DTC P0468 yuav suav nrog cov hauv qab no:

• Tshawb xyuas lub cav: Lub teeb pom kev ntawm lub teeb pom kev hauv lub tshuab hluav taws xob ntawm koj lub dashboard tej zaum yuav yog thawj qhov teeb meem.
• Kev ua haujlwm tsis ruaj khov ntawm lub cav: Ib theem teeb liab siab los ntawm kev tshem tawm huab cua ntws tuaj yeem ua rau lub cav tsis ruaj khov, suav nrog jerking lossis txawm tias tsis ua haujlwm thaum tsav tsheb.
• Kev siv roj ntau ntxiv: Kev ua haujlwm tsis raug ntawm cov evaporative emission system tuaj yeem ua rau muaj roj ntau ntxiv vim qhov sib xyaw ntawm cov roj thiab cua tsis raug.
• qis zog: Kev sib xyaw tsis zoo ntawm cov roj thiab cua tuaj yeem txo lub zog ntawm lub cav, ua rau lub tsheb tsis zoo.
• Cov suab tsis zoo los yog kev vibrations: Qee qhov xwm txheej, theem teeb liab siab los ntawm lub tshuab nqus cua ntws tawm tuaj yeem ua rau lub suab txawv txav lossis vibrations thaum lub cav khiav.

Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov tsos mob no tuaj yeem tshwm sim rau qhov sib txawv thiab yuav nyob ntawm qhov teeb meem tshwj xeeb thiab hom tsheb. Yog tias koj pom ib qho ntawm cov tsos mob no, nws raug nquahu kom koj hu rau tus kws kho tsheb tam sim ntawd txhawm rau kuaj xyuas thiab kho qhov teeb meem.

Yuav ua li cas kuaj tau tus lej txhaum P0468?

Txhawm rau kuaj xyuas DTC P0468, ua raws li cov kauj ruam no:

1. Tshawb xyuas cov lej yuam kev: Siv OBD-II scanner los kuaj xyuas cov lej yuam kev uas yuav khaws cia rau hauv lub cav tswj module (PCM). Paub txog cov lej ntxiv uas yuav tshwm sim nrog P0468.
