P0407 Izinga eliphansi lesifunda senzwa B yohlelo lokukhipha igesi qeda

Ikhodi Yenkinga ye-OBD-II - P0407 - Ishidi Ledatha

I-P0407 - Isignali ephansi kumjikelezo we-exhaust gas recirculation sensor B.

I-P0407 iyikhodi evamile ye-OBD-II yenkinga ye-voltage ye-EGR lapho isignali ethunyelwe isuka kumjikelezo ukuya kukhompyutha yenjini iphansi ngokungavamile futhi ayifani nemingcele eyamukelwayo yomkhiqizi.

Isho ukuthini ikhodi yenkinga P0407?

Le khodi iyikhodi yokudlulisela ejwayelekile. Kubhekwa njengendawo yonke njengoba kusebenza kukho konke ukwakheka namamodeli ezimoto (1996 nangaphezulu), yize izinyathelo ezithile zokulungisa zingahluka kancane ngokuya ngemodeli.

Kunemiklamo ehlukene yezinhlelo zokuphindaphinda igesi ephumayo, kodwa zonke zisebenza ngendlela efanayo. I-Exhaust Gas Recirculation Valve iyivalvu elawulwa yi-PCM (I-Powertrain Control Module) evumela amanani alinganiselwe amagesi e-exhaust ukuthi adlule abuyele kumasilinda ukuze ashiswe kanye nengxube yomoya/yamafutha. Ngenxa yokuthi amagesi e-exhaust ayigesi engasebenzi esusa umoya-mpilo, ukuwajova abuyele kusilinda kungehlisa izinga lokushisa elivuthayo, okusiza ukunciphisa ukukhishwa kwe-NOx (nitrogen oxide).

I-EGR ayidingeki ngesikhathi sokuqala esibandayo noma sokufaka idling. I-EGR inikwe amandla ngaphansi kwezimo ezithile, njengokuqala noma idling. Ukuphindiselwa kwegesi ekhishwa kunikezwa ngaphansi kwezimo ezithile, njengokuphenduka okuyingxenye noma ukwehla, kuye ngokushisa kwenjini nomthwalo, njll. Amagesi okukhipha ahlinzekwa ku-valve ye-EGR evela kumbhobho wokukhipha, noma i-valve ye-EGR ingafakwa ngqo kumaningi wokukhipha . Uma kunesidingo, i-valve iyasebenza, ivumela amagesi ukuthi angene kumasilinda. Amanye amasistimu aqondisa amagesi okukhipha ngqo kumasilinda, kanti amanye avele awajoje ezinqwabeni zokungenisa, kusuka lapho adonswa khona kumasilinda. kanti abanye bavele bayijoje ezinhlangothini eziningi zokudla, kusuka lapho bese idonswa kumasilinda.

Ezinye izinhlelo ze-EGR zilula impela, kanti ezinye ziyinkimbinkimbi ngokwengeziwe. Amaphayiphu wokuphinda ugesi aphethwe ugesi alawulwa ngqo yikhompyutha. Ihanisi ixhuma ku-valve uqobo futhi ilawulwa yi-PCM lapho ibona isidingo. Kungaba izintambo ezi-4 noma ezi-5. Ngokujwayelekile izizathu ezi-1 noma ezi-2, isekethe lokushisa elingu-12V, isekethe lesethenjwa elingu-5V, kanye nesekethe yempendulo. Ezinye izinhlelo zilawulwa ngomshini. Iqondile impela. I-PCM ilawula i-vacuum solenoid okuthi, uma ivulwa, ivumele i-vacuum ukuthi iye futhi ivule i-valve ye-EGR. Lolu hlobo lwe-valve ye-EGR kufanele futhi lube nokuxhumeka kagesi kwesekethe yempendulo. I-loop yempendulo ye-EGR ivumela i-PCM ukuthi ibone ukuthi iphini ye-valve ye-EGR empeleni ihamba kahle yini.

Uma isekethe lempendulo lithola ukuthi i-voltage iphansi ngokungavamile noma ingaphansi kwamandla kagesi acacisiwe, i-P0407 ingasethwa.

Qaphela: le khodi icishe ifane ne-p0405. Umehluko ukuthi i-DTC p0405 isho inzwa "A" kuthi i-P0407 ibhekisele kunzwa ye-EGR "B". Bheka ibhukwana elithile lokulungiswa kwezimoto ukuthola izinzwa "A" kanye "B".

Izimpawu

Izinjini eziningi azidingi ukuthi amasistimu e-EGR asebenze kahle njengoba ethobelana nemithethonqubo yokukhipha umoya. Lokhu kusho ukuthi ngekhodi engu-P0407, maningi amathuba okuthi umshayeli angaboni izimpawu ngaphandle kwesibani se-Check Engine. Kwezinye izimo, kungase kube khona ukwehla kokusetshenziswa kukaphethiloli noma ukushintshashintsha kancane ngesikhathi sokusheshisa.

Izimpawu zekhodi yenkinga ye-P0407 zingafaka:

• Ukukhanya kwe-MIL (Inkomba Yokungasebenzi)

Izimbangela zephutha P0407

Nakuba i-P0407 ingase ibangelwe izinkinga zomhlaba noma ikhompyutha yenjini engalungile, imbangela evame ukuba yivalvu ye-EGR ngokwayo. Ezinye izimbangela ezingenzeka zihlanganisa:

• I-valve ye-vacuum solenoid enephutha ye-EGR
• I-valve ye-EGR engalungile
• Isekhethi emfushane kusekethi ye-EGR
• Isekhethi emfushane kusekethi ye-EGR
• Izintambo ezingalungile ukusuka kuyunithi yokulawula injini ukuya kusistimu ye-EGR
• Iyunithi yokulawula injini enephutha
• Mfushane phansi emjikelezweni wesiginali we-EGR noma amasekethe wesethenjwa
• Isifunda esifushane kumandla wesekethe womhlaba noma amasekethe wesiginali wohlelo lokukhipha igesi qeda
• I-valve engalungile ye-EGR
• Izinkinga zokufaka izintambo ezimbi ze-PCM ngenxa yamatheminali abraded noma akhululekile

Izixazululo ezingenzeka

Uma ukwazi ukufinyelela ithuluzi lokuskena, ungalawula i-EGR valve ON. Uma iphendula futhi impendulo ikhombisa ukuthi i-valve ihamba kahle, inkinga ingahle ibe ngezikhathi ezithile. Kwesinye isikhathi, esimweni sezulu esibandayo, umswakama ungabanda ku-valve, ubangele ukuthi unamathele. Ngemuva kokufudumeza imoto, inkinga inganyamalala. I-Carbon noma enye imfucumfucu ingabambeka ku-valve ibangele ukuthi inamathele.

Uma i-valve yokukhipha igesi engaphenduli kwimiyalo yethuluzi lokuskena, nqamula isixhumi segesi yokukhipha igesi. Jika ukhiye uye endaweni, injini icishiwe (KOEO). Sebenzisa i-voltmeter ukuhlola u-5 V ekuholeni kokuhlolwa kwe-valve ye-EGR. Uma kungekho volts ama-5, ngabe kukhona amandla kagesi nhlobo? Uma i-voltage ingama-volts ayi-12, lungisa okufushane kuya ku-voltage kusifunda sereferensi se-volt engu-5. Uma kungekho-voltage ekhona, xhuma isibani sokuhlola kumandla ebhethri bese uhlola ucingo lwereferensi engu-5 V. Uma isibani sokuhlola sikhanyisa, isekethe lereferensi elingu-5 V lifinyelelwe phansi. Lungisa uma kunesidingo. Uma isibani sokuhlola singakhanyisi, hlola isekethe lereferensi elingu-5 V ukuze uvuleke. Lungisa uma kunesidingo.

Uma ingekho inkinga esobala futhi ingekho ireferensi ye-volt engu-5, i-PCM ingahle ibe nephutha, kepha amanye amakhodi kungenzeka abekhona. Uma ama-volts ama-5 akhona kusifunda sereferensi, xhuma i-5 volt jumper wire kusifunda sesiginali se-EGR. Ithuluzi lokuskena indawo yokukhipha igesi manje kufanele ifunde amaphesenti ayi-100. Uma ingaxhumi isibani sokuhlola kumthamo webhethri, hlola isekethe yesiginali yokuphindwa kabusha kwegesi yokukhipha. Uma ivuliwe, isifunda sesiginali sifushiselwa phansi. Lungisa uma kunesidingo. Uma inkomba ingakhanyisi, hlola ukuvuleka kwisekethe yesiginali ye-EGR. Lungisa uma kunesidingo.

Uma, ngemuva kokuxhuma isekhethi lereferensi engu-5 V kusiginali yesiginali ye-EGR, ithuluzi lokuskena libonisa indawo ye-EGR engamaphesenti ayi-100, hlola ukungezwani okungalungile kumatheminali esixhumi se-valve se-EGR. Uma i-wiring ilungile, shintsha i-valve ye-EGR.

Amakhodi E-EGR Ahlanganisiwe: P0400, P0401, P0402, P0403, P0404, P0405, P0406, P0408, P0409

AMAPHUTHA AVAMILE LAPHO KUHLOLWA IKHODI P0407

Ngokudabukisayo, i-valve ye-EGR ayihlali iyimbangela yekhodi ye-P0407, futhi kungabiza ukuyishintsha ngokushesha ngaphandle kokuxilongwa okufanele. Kufanele uhlole izingxenye ezingabizi kakhulu kuqala, njenge-wiring ne-solenoid, ngaphambi kokufaka i-valve ngokwakho. Ukuhlanza ishibhile kunokushintsha.

IYIZINKANI IKHODI P0407?

I-valve ye-EGR engalungile ingakhuphula umoya wemoto yakho futhi ithinte ukusebenza kwayo, kodwa ngokuvamile ayibangeli imiphumela emibi kakhulu. Kufanele ukuhlole ngokushesha noma kamuva, kodwa uhambo olusheshayo olumbalwa nge-P0407 ngeke kwenze noma yimuphi umonakalo omkhulu.

YIKUPHI UKULUNGISA ONGALUNGISA IKHODI P0407?

Ukulungiswa okuvame kakhulu kwe-P0407 imi kanje:

• Sula ikhodi ngesikena futhi ubeke iso kukhodi ezobuyiswa.
• Hlola ngokubuka i-valve ye-EGR kanye nezintambo ezihlotshaniswayo nemigqa yokuvala ukuze uthole izinkinga ezisobala.
• Hlanza i-valve ye-EGR, sula ikhodi bese ubona ukuthi isilawuli siyasebenza futhi.
• Hlola i-voltage ne-grounding, lungisa izintambo uma kunesidingo.
• Hlola imigqa ye-vacuum ku-EGR kanye ne-EGR solenoid - lungisa uma kunesidingo.
• Vula futhi uvale umazibuthe ukuze uhlole ukuthi isebenza kahle yini.
• Shintshanisa i-valve ye-EGR.

IMIBONO ENGEZIWE MAYELANA NEKHODI P0407 CABANGA

I-P0407 akuyona ikhodi yenjini ebangela ukwethuka, kodwa futhi akufanele ishaywe indiva njengoba amasistimu e-EGR edlala indima ebalulekile ekwehliseni i-carbon footprint yemoto. Ama-valve amaningi kuzoba lula ukuwathola njengoba evamise ukuba seduze nendawo edonsayo injini ukuze amagesi e-exhaust akwazi ukujikeleza kabusha. Kwezinye izimoto ezisetshenzisiwe, abanikazi bangaphambili bazisusile lezi zinhlelo ukuze zibe lula.
