P04A2 Isignali ephezulu yegesi yokukhipha ingcindezi yokulawula igesi B

Idatha ye-OBD-II DTC

I-valve elawula ukucindezela kwegesi ephumayo "B" iphezulu

Kusho ukuthini lokhu?

Le Generic Transmission / Engine DTC imvamisa isebenza ezinjinini zikadizili okubandakanya, kodwa kungagcini lapho, ezimotweni ezithile zeFord Powerstroke, Dodge Cummins, Mercedes, Nissan, neVW.

Le khodi ingasetshenziswa nasemalolini anezinjini zikadizili namabhuleki e-exhaust afakwe kumthengisi.

I-valve ibekwa emfudlaneni we-exhaust ongaphansi kobubanzi be-exhaust ukukhiqiza ukushisa ngendlela yengcindezi yangemuva ku-qeda. Lokhu kushisa kanye / noma ingcindezi yangemuva kungasetshenziselwa ukufudumala ngenkathi kuqala ukubanda. Ingasetshenziswa futhi ukumelana nengcindezi emasilindini aqhamuka kumasilinda wenjini avela kumagesi e-exhaust, ngaleyo ndlela anciphise injini nemoto nayo. Lokhu kuyasiza ikakhulukazi lapho kudonswa.

Le khodi ibhekise eqinisweni lokuthi isignali yokufaka evela kwinzwa yokucindezela igesi ayifani nengcindezi yokudla okuningana noma ingcindezi yomoya ngesikhathi sokushayela okujwayelekile. Lokhu kungaba inkinga yomshini noma iphutha likagesi, kuya ngomkhiqizi wemoto.

Izinyathelo zokuxazulula inkinga zingahluka ngokuya ngomkhiqizi, uhlobo lwesilawuli sokuqeda ukucindezela emuva kanye nemibala yezintambo ku-solenoid yokulawula. Bheka ibhukwana lakho lokulungisa izimoto ukuthola ukuthi iyiphi i-valve "B" eyenzelwe icala lakho.

izimpawu

Izimpawu zekhodi yenjini engu-P04A2 zingafaka:

• Ilambu Lenkomba Yokungasebenzi (MIL) likhanyisiwe
• Ukuntuleka kwamandla
• Ayikho ibhuleki yenjini
• Yinde kunesikhathi esivamile sokufudumeza injini ebandayo

Izimbangela Ezingenzeka P04A2

Imvamisa isizathu sokufaka le khodi sithi:

• Stuck qeda emuva ingcindezi valve
• Ukukhipha okulinganiselwe
• Vula isekethe lomhlabathi kunzwa yokukhipha ingcindezi yegesi
• Vula isekethe yesiginali phakathi kwenzwa yokucindezela kwe-exhaust ne-PCM
• Isifunda esifushane ku-voltage kusifunda sesiginali senzwa yokucindezela igesi
• Inzwa yokucindezela kwe-exhaust enephutha - ukufushane kwangaphakathi ku-voltage
• Ishubhu yokucindezela inzwa yokucindezela igesi evimbekile
• I-turbocharger ingahle ilayishwe ngokweqile.
• Kungenzeka ukuthi i-PCM iphahlazekile (akunakwenzeka)

Izinqubo zokuxilonga nokulungisa

Iphuzu elihle lokuqala ngaso sonke isikhathi ukuthola i-Technical Service Bulletin (TSB) yemoto yakho ethile. Umkhiqizi wezimoto angaba ne-flash memory / PCM reprogramming ukulungisa le nkinga futhi kufanele uyihlole ngaphambi kokuthi uzithole uhamba indlela ende / engalungile. I-PCM = Imodyuli Yokulawula i-Powertrain.

Bese uthola inzwa ye-exhaust pressure ethi “B” emotweni yakho ethile. Uma usutholakele, bheka ngokubukeka izixhumi nezintambo. Bheka ama-scuffs, ama-scuffs, izintambo ezivuliwe, izimpawu zokusha, noma ipulasitiki encibilikisiwe. Nqamula izixhumi futhi uhlole ngokucophelela amatheminali (izingxenye zensimbi) ngaphakathi kwezixhumi. Bona ukuthi zibukeka zigqwalile, zishile, noma ngokunokwenzeka ziluhlaza uma ziqhathaniswa nombala wensimbi ovamile cishe ojwayele ukuwubona. Uma ukuhlanzwa kwetheminali kuyadingeka, ungathenga isihlanzi sikagesi kunoma yisiphi isitolo sezingxenye. Uma lokhu kungenzeki, thola u-91% wotshwala obuhlikihla kanye nebhulashi elincane le-bristle lepulasitiki ukuze uzihlanze. Bese uziyeke zome emoyeni, uthathe inhlanganisela ye-silicone ye-dielectric (into efanayo abayisebenzisela izibambi zama-bulb nezintambo ze-spark plug) futhi ubeke lapho amatheminali ethintana khona.

Futhi, uma imoto yakho ifakwe, susa ishubhu yenzwa exhuma inzwa yokucindezela emuva emuva kokuphindaphinda. Zama ukugqashula kulokhu. Uma lokhu kungenzeki, lokhu futhi kuyisizathu sokuthi le khodi ivele.

Uma unethuluzi lokuskena, sula amakhodi ezinkinga zokuxilonga kwimemori bese ubona ukuthi ikhodi iyabuya yini. Uma lokhu kungenjalo, kungenzeka ukuthi kunenkinga yokuxhuma.

Uma ikhodi ibuya, kuzodingeka uhlole ukuthi ukukhuphula i-turbocharger kusebenza kahle. Uzodinga ithuluzi lokuskena elingafunda ingcindezi yokuqinisa i-turbocharger. Ungadinga ukuqapha ingcindezi eningi yokudla ngoba lokhu kuzokunikeza imininingwane efanayo. Naka ingcindezi ngokhiye uvuliwe, kodwa injini icishiwe. Bese uqala injini, ushayele imoto ngejubane eliphephile, bese uyisheshisa kancane kancane injini ifike kuvuleke mpintsha ivuleke, uqiniseke ukuthi isivinini senjini asidluli ku-2500-3000 rpm. Kufanele uqaphele ushintsho okungenani lwe-18 psi, mhlawumbe ngaphezulu ngokuya ngomkhiqizi wezimoto nonyaka wemodeli.

Uma lokhu kuhlolwa kudlula noma ungakwazi ukuhlola amandla we-turbocharger, kuzodingeka sihlole inzwa namasekhethi ahlobene. Ngokuvamile kunezintambo ezi-3 kunzwa yokucindezela kokukhipha.

Nqamula i-harness kusuka kunzwa yokucindezela yokukhipha. Sebenzisa i-digital volt ohmmeter (i-DVOM) ukubheka isekethe yokuphakelwa kwamandla ka-5V eya enzwa ukuqinisekisa ukuthi ivuliwe (ucingo olubomvu kuya ku-5V wesekethe yokuhambisa ugesi, ucingo olumnyama emhlabathini omuhle). Uma inzwa ingama-volts ayi-12 lapho kufanele kube ama-volts ama-5, lungisa i-wiring kusuka ku-PCM iye kwinzwa ngama-volts amafushane kuya kwayi-12 noma i-PCM enephutha.

Uma lokhu kujwayelekile, ne-DVOM, qiniseka ukuthi une-5V kusekethe yesignali yesignali yesifutho (ucingo olubomvu ukuya kusiginali yesiginali yenzwa, ucingo olumnyama kumhlabathi omuhle). Uma kungekho-volts ama-5 enzwa, noma uma ubona ama-volts ayi-12 enzwa, lungisa i-wiring kusuka ku-PCM iye kwinzwa, noma futhi, mhlawumbe i-PCM enephutha.

Uma kujwayelekile, hlola ukuthi inzwa yengcindezi yokukhipha isisekelo esifanele yini. Xhuma isibani sokuhlola ku-12 V battery positive (i-terminal ebomvu) bese uthinta omunye umkhawulo wesibani sokuhlola esisekelweni somhlaba esiholela emhlabathini wesifunda sokucindezela igesi. Uma isibani sokuhlola singakhanyi, sikhombisa isifunda esingalungile. Uma ifika, nyakazisa amahanisi wezintambo uya kunzwa yengcindezi yokukhipha ukuze ubone ukuthi isibani sokuhlola siyacwayiza yini, okukhombisa ukuxhumana okuphakathi.

Uma zonke izivivinyo zangaphambilini zidlulile futhi uqhubeka nokuthola ikhodi ye-P04A2, cishe izobonisa inzwa yokucindezela yokuphelelwa amandla engalungile, nakuba i-valve yokucindezela ephumayo evaliwe ibambekile noma i-PCM ehlulekile ayikwazi ukukhishwa kuze kube yilapho inzwa izoshintshwa.
