P0405 Isibonisi esiphansi sesekena senzwa A yohlelo lokukhipha igesi qeda

Ikhodi Yenkinga ye-OBD-II - P0405 - Ishidi Ledatha

Ileveli yesignali ephansi kusekethe yenzwa yokukhipha igesi ephumayo.

I-P0405 iyikhodi evamile ye-OBD-II ebonisa ukuthi I-Engine Control Module (ECM) ithole ukuthi inzwa ye-Engine Exhaust Gas Recirculation (EGR) ayikho ebangeni. Okokufaka kwenzwa okufushane ukuya phansi ku-ECM.

Isho ukuthini ikhodi yenkinga P0405?

Le Khodi Yezinkinga Zokuxilonga (i-DTC) yikhodi yokudlulisela ejwayelekile, okusho ukuthi isebenza ezimotweni ezihlomele i-OBD-II. Yize kuvamile emvelweni, izinyathelo ezithile zokulungisa zingahluka ngokuya ngohlobo lomkhiqizo / imodeli.

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-12 volt, isekhethi eliyi-5 volt, 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. Impendulo ye-valve 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-P0405 ingasethwa.

Izimpawu

Izimpawu zekhodi yenkinga ye-P0405 zingafaka:

• Ukukhanya kwe-MIL (Inkomba Yokungasebenzi)
• Ukukhanya Kwenjini Yokuhlola kuzokhanya futhi ikhodi izogcinwa ku-ECM.
• I-ECM ingase ivule i-valve ye-EGR ngaphezu kwalokho okudingekayo uma i-voltage iphansi kakhulu, okubangela injini ukuthi ime noma inyakaze lapho igijima.
• Isistimu ye-EGR yenjini ingabangela injini ukuthi isebenze kabi, igwebe, noma imile uma ingabonisi indawo elungile yevalvu ye-EGR ku-ECM.
• I-ECM ingakwazi ukuvimba i-valve ukuthi ingavuleki lapho ibona ukungasebenzi kahle, futhi injini ingavutha ngaphambili uma isheshisa.

Izimbangela zephutha P0405

Izimbangela ezingaba khona zekhodi ye-P0405 zifaka:

• 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, P0406, P0407, P0408, P0409

IYENZA KANJANI IKHODI YE-MCHHANIC DIAGNOSTIC P0405?

• Iskena amakhodi nedatha imisa amadokhumenti ozimele ukuze kuqinisekiswe inkinga
• Sula amakhodi enjini nokuhlolwa komgwaqo ukuze ubone ukuthi ukwesaba namakhodi kuyabuya yini.
• Igada i-pid yenzwa ye-EGR kusikena ukuze ibone ukuthi ingabe inzwa ikhombisa ukuthi ivalvu isendaweni efanele evaliwe noma uma impendulo ye-voltage yenzwa ingaphansi kwesicaciso.
• Ikhipha isixhumi senzwa ye-EGR, ihlola isixhumi ukugqwala futhi isihlanze uma kudingeka.
• Hlola isixhumi uma ireferensi engu-5 volt ifinyelela kusixhumi senzwa.
• Xhuma i-voltage yereferensi yenzwa kanye nezikhonkwane zempendulo bese uhlola isikena ukuze ubonise amandla kagesi ayireferensi kunzwa ye-pid yenzwa ye-EGR.
• Ingena esikhundleni senzwa ye-EGR noma ilungisa izintambo njengoba kudingeka, bese ihlola kabili ukufundwa kwesistimu okulungile.

AMAPHUTHA AVAMILE LAPHO KUHLOLWA IKHODI P0405

• Ungaxhumi i-voltage yereferensi yenzwa kanye nesignali yempendulo ndawonye ukuze uqiniseke ukuthi zonke izintambo zilungile ngaphambi kokushintsha inzwa yendawo ye-EGR.
• Ukuhluleka ukuhlola izintambo nokuxhumeka kunzwa yendawo ye-EGR ukuze uthole isekethe emfushane noma isekethe evulekile ngaphambi kokushintsha inzwa yendawo ye-EGR.

IYIZINKANI IKHODI P0405?

• I-ECM ingakhubaza isistimu ye-EGR futhi iyenze ingasebenzi uma le khodi isebenza.
• Ukukhanya kwesibani se-Check Engine kuzoholela ekuhlulekeni kokuhlolwa kwe-emission.
• Ukuma kwe-EGR kubalulekile ukuze i-ECM ilawule kahle ukuvulwa nokuvalwa kwe-valve ye-EGR futhi ingabangela injini ukuba ihambe kabi futhi ime.

YIKUPHI UKULUNGISA ONGALUNGISA IKHODI P0405?

• Shintshanisa inzwa yendawo ye-EGR, wenze isiqiniseko sokuthi izintambo zilungile.
• Okunamathiselwe Kwezintambo Ezimfushane Kunzwa Yesimo Se-EGR noma Isixhumi Sokubuyisela Isiginali
• Ukuqedwa kwekhefu ku-voltage eyireferensi kunzwa ye-EGR

IMIBONO ENGEZIWE UKUZE UQAPHELE IKHODI P0405

Ikhodi P0405 iqalwa lapho indawo ye-EGR iphansi kunendawo yenzwa ye-ECM elindelwe futhi imbangela evame kakhulu ukuthi inzwa ye-EGR inomjikelezo ovulekile wangaphakathi.
