P0454 Evaporator Emission System Siab Sensor Intermittent
OBD-II DTC Cov Ntaub Ntawv
Intermittent teeb liab ntawm lub siab sensor ntawm kev tswj qhov system rau tshem tawm cov roj vapor
Qhov no txhais li cas?
Qhov Diagnostic Trouble Code (DTC) yog tus lej siv dav dav, uas txhais tau tias nws siv rau OBD-II cov tsheb nruab (Dodge, Ram, Ford, GMC, Chevrolet, VW, Audi, Toyota, thiab lwm yam). Txawm hais tias dav dav, cov kev kho tshwj xeeb yuav txawv nyob ntawm cov khoom lag luam / qauv.
Thaum koj lub OBD-II nruab lub tsheb qhia code P0454, nws txhais tau hais tias lub powertrain control module (PCM) tau kuaj pom lub teeb liab tsis sib xws ntawm EVAP siab sensor Circuit Court.
Txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau nkag mus rau hauv cov huab cua, EVAP system siv lub vented reservoir.
Roj tank vapors raug tso tawm los ntawm kev nyab xeeb valve (nyob rau sab saum toj ntawm lub tank roj). Lub siab generated thaum lub sij hawm cia cov roj ua raws li ib tug propellant thiab yuam kom cov vapors khiav los ntawm ib tug network ntawm cov kav hlau thiab roj hmab hoses; nws thiaj li tau mus rau charcoal storage canister. Lub canister tsis tsuas yog absorbs roj vapors, tab sis kuj tuav lawv tso tawm thaum lub sijhawm.
Ib tug raug EVAP system muaj xws li ib tug carbon tank, ib tug EVAP siab sensor, purge valve / solenoid, lub tso pa tswj valve / solenoid, thiab ib tug intricate system ntawm hlau kav thiab roj hmab hoses uas khiav ntawm lub roj tank mus rau lub cav compartment.
Lub purge tswj valve / solenoid, uas yog lub hub ntawm EVAP system, yog hluav taws xob tswj los ntawm PCM. Purge tswj valve / solenoid yog siv los tswj lub tshuab nqus tsev ntawm qhov nkag mus rau EVAP lub kaus mom kom cov roj vapors tau kos rau hauv lub cav thaum muaj xwm txheej zoo rau hlawv li roj es tsis txhob ua rau huab cua phem.
EVAP siab yog saib xyuas los ntawm PCM siv lub EVAP siab sensor. Lub EVAP siab sensor tuaj yeem nkag mus tau yooj yim vim nws feem ntau nyob rau sab saum toj ntawm lub tank roj thiab ua rau hauv lub twj tso kua mis / roj xa khoom vaj tsev. Yog tias PCM pom tias EVAP lub teeb liab siab tsis sib xws, tus lej P0454 yuav raug khaws cia thiab lub teeb pom kev tsis zoo (MIL) tuaj yeem teeb pom kev.
Cov teeb meem cuam tshuam nrog DTCs suav nrog P0450, P0451, P0452, P0453, P0455, P0456, P0457, P0458, thiab P0459.
Txoj cai hnyav thiab cov tsos mob
Cov tsos mob ntawm txoj cai no suav nrog:
- Feem ntau, cov tsos mob nrog tus lej P0454 yuav tsis tshwm sim.
- Kev txo qis hauv roj efficiency
- MIL Illumination (Teeb Pom Teeb Pom Teeb)
yog vim li cas
Qhov laj thawj ua rau teeb tsa cov cai no:
- Ua tsis tau zoo EVAP siab sensor
- Roj tank nyem valve txhaws.
- Qhib lossis luv Circuit Court hauv cov xaim lossis cov khoom sib txuas ntawm EVAP siab sensor
- Qhib los yog tawg Charcoal Canister
Kev kuaj mob thiab kho cov txheej txheem
Yog tias kuv tuaj hla P0454 tus lej kuaj mob, kuv paub tias kuv yuav xav tau lub tshuab kuaj kab mob, lub tshuab hluav taws xob digital / ohmmeter, cov ntaub ntawv xov xwm tsheb zoo ib yam li Txhua Cov Ntaub Ntawv DIY, thiab tej zaum txawm tias lub tshuab pa luam yeeb.
Kev soj ntsuam pom ntawm cov hoses, kab, cov hlua hluav taws xob, thiab cov khoom sib txuas ntawm EVAP system yog qhov chaw zoo pib kuaj mob. Ua tib zoo saib xyuas qhov chaw nyob ze ntawm cov npoo ntse lossis cov khoom siv hluav taws xob kub. Tsis txhob hnov qab tshem lub hau roj tank, tshuaj xyuas lub foob thiab kaw kom zoo.
Tom qab ntawd kuv nyiam txuas lub scanner rau lub tsheb kuaj xyuas qhov chaw nres nkoj thiab khaws tag nrho cov lej khaws cia thiab khov cov ntaub ntawv. Nws yog ib lub tswv yim zoo los sau cov ntaub ntawv no vim nws tuaj yeem muaj txiaj ntsig zoo, tshwj xeeb tshaj yog tias nws hloov mus ua ntu ntu ntu. Tom qab ntawd, kuv nyiam tshem cov lis dej num thiab sim tsav lub tsheb kom txog thaum nws nkag mus rau OBD-II hom npaj txhij lossis cov lej raug tshem tawm. EVAP cov lej feem ntau xav tau ntau lub voj voog tsav (nrog txhua qhov tsis ua haujlwm) ua ntej rov pib dua.
Saib xyuas lub teeb liab los ntawm EVAP siab sensor siv lub scanner tus kab mob. Kuv paub tias kuv tau kho qhov xwm txheej (los ntawm kev nruj lossis hloov lub hau roj) yog tias lub kaw lus siab nyob hauv cov chaw tsim khoom tau pom zoo,
Kuv yuav tshawb xyuas EVAP siab sensor ua ntej ua qhov ntsuas pa luam yeeb vim nws yog ib qho kev sib cuam tshuam ntawm qhov ntsuas ntsuas hluav taws xob. Qhov chaw ntawm EVAP siab sensor tuaj yeem cuam tshuam qhov kev xeem raws li nws feem ntau nyob rau saum lub tank roj. Thaum nkag mus rau lub sensor, ua raws li cov chaw tsim tshuaj ntsuam cov lus qhia thiab hloov lub sensor yog tias nws tsis yog specification.
Tshem tawm tag nrho cov tswj kev sib txuas thiab xyuas ib tus neeg lub voj voog nrog DVOM yog EVAP siab sensor raws li cov chaw tsim khoom tshwj xeeb. Kho lossis hloov qhov qhib lossis luv Circuit Court raws li qhov tsim nyog thiab rov ua dua lub kaw lus.
Cov ntawv kuaj mob ntxiv:
- Tsawg lossis siab EVAP siab tuaj yeem ua rau P0454 nyob ruaj khov.
- Txoj cai no tuaj yeem tshwm sim los ntawm teeb meem hluav taws xob lossis tshuab.
