I-P0454 Evaporator Emission System Pressure Sensor Intermittent

I-P0454 Evaporator Emission System Pressure Sensor Intermittent

Idatha ye-OBD-II DTC

Isiginali engena ngaphakathi esenzweni sokucindezela sohlelo lokulawula ukususwa komphunga kaphethiloli

Kusho ukuthini lokhu?

Le Khodi Yezinkinga Zokuxilonga (i-DTC) yikhodi yokudlulisela ejwayelekile, okusho ukuthi isebenza ezimotweni ezifakiwe ze-OBD-II (iDodge, iRam, iFord, i-GMC, i-Chevrolet, i-VW, i-Audi, iToyota, njll.). Yize kuvamile emvelweni, izinyathelo ezithile zokulungisa zingahluka ngokuya ngohlobo lomkhiqizo / imodeli.

Lapho imoto yakho ene-OBD-II ikhombisa ikhodi engu-P0454, kusho ukuthi imodyuli yokulawula amandla we-powertrain (PCM) ithole isignali engenayo evela kusekethe ye-EVAP pressure sensor circuit.

Ukubamba umusi kaphethiloli ngaphambi kokuba abalekele emkhathini, uhlelo lwe-EVAP lisebenzisa inqolobane evunguziwe (evame ukubizwa ngokuthi i-canister) ukugcina umusi owedlulele uphethiloli kuze kube yilapho injini isebenza ngaphansi kwezimo ezifanele ukuzishisa kahle.

Imiphunga ethangini likaphethiloli ikhishwa nge-valve yokuphepha (phezulu ethangini likaphethiloli). Ingcindezi eyenziwe ngesikhathi sokugcinwa kukaphethiloli isebenza njengesihambisayo futhi iphoqa ukuba umhwamuko ubaleke ngenethiwekhi yamapayipi ensimbi namabhande enjoloba; ekugcineni ufike ebhokisini lokugcina amalahle. I-canister ayigcini nje ngokumunca umusi kaphethiloli, kodwa futhi iyabamba ukuze ikhululwe ngesikhathi esifanele.

Uhlelo olujwayelekile lwe-EVAP luqukethe ithangi lekhabhoni, inzwa yengcindezi ye-EVAP, i-purge valve / solenoid, i-exhaust control valve / solenoid, kanye nohlelo oluyinkimbinkimbi lwamapayipi ensimbi namapayipi enjoloba asuka ethangini likaphethiloli aye egunjini lenjini.

I-purge control valve / solenoid, okuyihabhu yohlelo lwe-EVAP, ilawulwa nge-elektroniki yi-PCM. I-purge control valve / i-solenoid isetshenziselwa ukulawula i-vacuum esangweni ku-EVAP canister ukuze kutholakale umusi kaphethiloli enjinini lapho izimo zilungele ukushiswa njengophethiloli esikhundleni sokungcolisa umoya.

Ingcindezi ye-EVAP ibhekwa yi-PCM isebenzisa inzwa yokucindezela ye-EVAP. Inzwa yengcindezi ye-EVAP ingaba nzima ukuyifinyelela njengoba imvamisa itholakala phezulu ethangini likaphethiloli futhi ishumekelwe kufemu yezindlu yepompo kaphethiloli / yokulethwa kukaphethiloli. Uma i-PCM ithola ukuthi isignali yengcindezi ye-EVAP iphakathi nendawo, kuzogcinwa ikhodi engu-P0454 bese ilambu le-Malfunction Indicator (MIL) lingakhanyisa.

Ama-DTC ahlanganisiwe afaka i-P0450, P0451, P0452, P0453, P0455, P0456, P0457, P0458, ne-P0459.

Ukuqina kwekhodi nezimpawu

Izimpawu zale khodi zingafaka:

• Ezimweni eziningi, izimpawu ezinekhodi engu-P0454 ngeke zivele.
• Nciphisa kancane ekusebenziseni uphethiloli
• Ukukhanya kwe-MIL (Isibani Sesikhombi Sokungasebenzi Kahle)

izizathu

Izizathu ezingaba khona zokusetha le khodi:

• Inzwa yengcindezi ye-EVAP engalungile
• Ivalu yethangi likaphethiloli ivalekile.
• Isifunda esivulekile noma esifushane ezintanjeni noma ezixhumi zenzwa yengcindezi ye-EVAP
• Ibhokisi Lamalahle Lamalahle Aqhekekile noma Aphukile

Izinqubo zokuxilonga nokulungisa

Uma ngithola i-P0454 diagnostic code, ngiyazi ukuthi ngizodinga isithwebuli sokuxilonga, i-digital volt / ohmmeter, umthombo othembekile wolwazi lwemoto njenge-All Data DIY, futhi mhlawumbe nomshini wentuthu.

Ukuhlolwa okubonakalayo kwamapayipi, imigqa, amahhanisi kagesi, nezixhumi zohlelo lwe-EVAP kuyindawo enhle yokuqala ukuxilonga. Naka ngokukhethekile izingxenye eziseduze nemiphetho ebukhali noma izingxenye zesistimu yokukhipha umoya oshisayo. Ungakhohlwa ukukhipha isivalo sethangi likaphethiloli, hlola uphawu bese uluqinisa ngendlela efanele.

Ngemuva kwalokho ngithanda ukuxhuma isithwebuli ethekwini lokuxilonga imoto bese ngithola wonke amakhodi agciniwe futhi ngifrize idatha yozimele. Kungumqondo omuhle ukubhala lolu lwazi phansi ngoba lungaba wusizo olukhulu, ikakhulukazi uma kutholakala ukuthi luyikhodi yezikhathi ezithile. Ngemuva kwalokho, ngithanda ukusula amakhodi nokuhlola ukushayela imoto ize ingene kumodi yokulungela i-OBD-II noma ikhodi isuliwe. Amakhodi we-EVAP adinga imijikelezo eminingi yedrayivu (ngokwehluleka ngakunye) ngaphambi kokusetha kabusha.

Bheka isignali evela kunzwa yokucindezela ye-EVAP usebenzisa ukusakazwa kokuxilongwa kwesithwebuli. Ngiyazi ukuthi ngisilungisile isimo (ngokuqinisa noma ngokufaka ikepisi likaphethiloli) uma ingcindezi yohlelo ingaphakathi kokucacisiwe komkhiqizi,

Ngingabheka inzwa yengcindezi ye-EVAP ngaphambi kokwenza ukuhlolwa kwentuthu ngoba iyikhodi yesekethe yokuzwa ingcindezi yangaphakathi. Indawo inzwa yengcindezi ye-EVAP ingaba nzima ekuhlolweni njengoba ijwayele ukutholakala phezulu kwethangi likaphethiloli. Lapho usufinyelele inzwa, landela imihlahlandlela yokuhlola yomkhiqizi bese ushintsha inzwa uma ingekho esimisweni.

Nqamula zonke izilawuli ezihambisanayo futhi uhlole amasekethe angawodwana nge-DVOM uma inzwa yengcindezi ye-EVAP ihlangabezana nokucaciswa komkhiqizi. Lungisa noma shintsha amasekethe avulekile noma amafishane njengoba kudingeka bese uphinde uzame uhlelo.

Amanothi wokuxilonga angeziwe:

• Ukucindezela okuphansi noma okuphezulu kwe-EVAP kungadala ukuthi i-P0454 iqhubeke.
• Le khodi ingadalwa yizinkinga zikagesi noma ezisebenza ngomshini.

Udinga usizo olwengeziwe ngekhodi le-p0454?

Uma usadinga usizo nge-DTC P0454, thumela umbuzo kumazwana angezansi kwalesi sihloko.

QAPHELA. Lolu lwazi lunikezwa ngenhloso yokwaziswa kuphela. Akuhloselwe ukuthi isetshenziswe njengesincomo sokulungisa futhi asinacala nganoma yisiphi isenzo osithathayo kunoma iyiphi imoto. Yonke imininingwane ekulesi siza ivikelwe yi-copyright.
