I-P045C Isifunda Esilawula Ukulawulwa Kwegesi Ephansi

Idatha ye-OBD-II DTC

Isiginali ephansi esifundeni sokulawula ukukhipha igesi "B"

Kusho ukuthini lokhu?

Le Khodi Yezinkinga Zokuxilonga (i-DTC) yikhodi yokudlulisela ejwayelekile, okusho ukuthi isebenza ezimotweni ezihlome nge-OBD-II ezine-EGR. Izinhlobo zezimoto zingafaka (kepha azikhawulelwanga) kwaLand Rover, GMC, Chevrolet, Dodge, Chrysler, Ford, Toyota, Honda, njll. Noma kunjalo, izinyathelo ezithile zokulungisa zingahluka ngohlobo / ngemodeli.

Lawa makhodi enkinga yenjini asho ukungasebenzi kahle kwesistimu yokukhipha igesi ephumayo. Ngokuqondile, isici sikagesi. I-exhaust gas recirculation system iyingxenye ebalulekile yesistimu yokukhipha imoto, umsebenzi wawo ukuvimbela ukwakheka kwe-NOx eyingozi (i-nitrogen oxides) kumasilinda.

I-EGR ilawulwa yikhompyutha yokuphathwa kwenjini. Ikhompyutha ivula noma ivale ukuphindaphinda kwegesi yokukhipha ngokuya ngomthwalo, isivinini kanye namazinga okushisa ukuze kugcinwe izinga lokushisa lekhanda lesilinda elifanele. Kunezintambo ezimbili kwi-solenoid kagesi ku-EGR esetshenziswa yikhompyutha ukuyenza isebenze. I-potentiometer nayo itholakala ku-exhaust gas recirculation solenoid, ekhombisa isikhundla senduku ye-EGR (indlela yokusebenza evula futhi ivale umgudu).

Lokhu kufana kakhulu nokufiphaza amalambu asekhaya lakho. Uma uvula iswishi, ukukhanya kuyakhanya njengoba amandla kagesi enyuka. Ikhompyutha yakho yenjini ayiluboni ushintsho lwamandla lapho izama ukuvula noma ukuvala i-EGR, ekhombisa ukuthi ibhajwe endaweni eyodwa. Amakhodi P045C Exhaust Gas Recirculation Control Circuit “B” akhombisi ukushintsha kwamandla aphansi, okukhombisa ukuthi i-EGR iyavula noma iyavala. I-P045D iyafana ngokuyisisekelo, kepha isho ukuphakama kwesekethe, hhayi okuphansi. Thintana nencwajana yakho yokulungisa izimoto ukuze unqume ukuthi isiphi isekethe lokucindezela igesi elingu- “B” kuhlelo lwakho lokusebenza.

Uphethiloli ongenawo uvame ukwakha i-NOx emazingeni okushisa we-cylinder eyedlulele. Uhlelo lwe-EGR luqondisa inani elilawulwayo lokukhipha igesi emuva kokuphindaphindwayo kokudla. Inhloso ukunciphisa ingxube kaphethiloli engenayo ngokwanele ukuletha ukushisa kwekhanda lesilinda ngaphansi kwalapho kwakhiwa khona i-NOx.

Ukusebenza kwesistimu ye-EGR ibalulekile ngenxa yezizathu eziningi kunokuvimbela i-NOx - inikeza isikhathi esinembe kakhudlwana samandla engeziwe ngaphandle kokungqongqoza, kanye nengxube ethambile kaphethiloli yomnotho ongcono kaphethiloli.

izimpawu

Izimpawu zizohluka ngokuya ngesikhundla senaliti ye-EGR ngesikhathi sokuhluleka.

• Injini egijimayo kakhulu
• Isibani senjini yokuhlola sivuliwe
• Ukuwa komnotho kaphethiloli
• Ukwehla kwamandla
• Akunasiqalo noma kunzima kakhulu ukuqala kulandelwe i-idle ebukhali

Izizathu ezingenzeka

Izizathu zale DTC zingafaka:

• Isifunda esifushane ukuya phansi
• Mfushane kumandla kagesi webhethri
• Isixhumi esibi nezikhonkwane ezikhishwe ngaphandle
• Ukugqwala kusixhumi
• Inaliti ye-EGR engcolile
• I-solenoid yokubuyisela kabusha igesi engalungile
• I-EGR embi
• I-ECU noma ikhompyutha enamaphutha

Izinqubo zokulungisa

Uma imoto yakho ihambe ngaphansi kwamamayela ayi-100,000 ayi-80, kunconywa ukuthi ubuyekeze iwaranti yakho. Izimoto eziningi ziphatha iwaranti yokulawula ukukhishwa kwamamayela ayi-100,000 noma i-XNUMX. Okwesibili, ngena ku-inthanethi bese uhlola wonke ama-TSB (Ama-Bulletin Wensizakalo Yezobuchwepheshe) ahlobene nala makhodi nokuthi angawalungisa kanjani.

Ukwenza lezi zinqubo zokuxilonga, uzodinga amathuluzi alandelayo:

• I-Volt / Ohmmeter
• Umdwebo wokuxhuma wokukhipha igesi
• Ijuma
• Iziqeshana ezimbili zephepha noma izinaliti zokuthunga

Vula i-hood bese uqala injini. Uma injini ingasebenzi kahle, susa ipulagi ohlelweni lwe-EGR. Uma injini ibushelelezi, iphini liyanamathela ku-EGR. Misa injini bese ushintsha i-EGR.

Bheka isixhumi sezintambo ku-"B" EGR. Kunezintambo ezi-5, izintambo ezimbili zangaphandle ziphakela i-voltage yebhethri nomhlabathi. Izintambo ezintathu ezimaphakathi ziyi-potentiometer ebonisa kukhompuyutha inani lokugeleza kwe-EGR. Itheminali emaphakathi iyitheminali eyinkomba engu-5V.

Hlolisisa isixhumi ngezikhonkwane ezikhishiwe, ukugqwala, noma izikhonkwane ezigoqiwe. Hlola i-harness wiring ngokucophelela nganoma yikuphi ukwahlukanisa noma amasekhethi amafushane. Bheka izintambo ezivulekile ezingavula isekethe.

• Sebenzisa i-voltmeter ukuhlola noma yikuphi ukuhola okubulalayo ngocingo olubomvu bese ugaya ucingo olumnyama. Vula ukhiye bese uthola ama-volts ayi-12 nawo womabili amatheminali okuphela.
• Uma i-voltage ingakhonjisiwe, khona-ke kukhona ucingo oluvulekile phakathi kohlelo lwe-EGR nebhasi lokuthungela. Uma ama-volts ayi-12 akhonjiswa ohlangothini olulodwa kuphela, isistimu ye-EGR inesifunda esivulekile sangaphakathi. Faka esikhundleni se-EGR.
• Nqamula isixhumi ohlelweni lokukhipha igesi qeda bese ucisha ukhiye nenjini, uhlole amandla oxhumana nabo bangaphandle bangaphandle. Bhala phansi ukuthi iyiphi enama-volts ayi-12 bese ushintsha isixhumi.
• Beka isiqeshana sephepha ku-terminal lug ebinganikwe amandla, lesi yisiga somhlabathi. Namathisela i-jumper esiqeshini se-paperclip. Phansi kweqa. "Ukuchofoza" kuzozwakala lapho kwenziwa i-EGR. Nqamula intambo yomhlabathi bese uqala injini. Phinda ucindezele ucingo futhi kulokhu injini izosebenza kanzima lapho i-EGR inikwa amandla futhi ithambile lapho umhlaba ususwa.
• Uma uhlelo lwe-EGR lusebenza futhi injini iqala ukusebenza ngezikhathi ezithile, uhlelo lwe-EGR luhlelekile, inkinga ingugesi. Uma kungenjalo, misa injini bese ushintsha i-EGR.
• Hlola indawo yokugcina yesikhungo sokuxhuma igesi. Vula ukhiye. Uma ikhompyutha isebenza kahle, kukhonjiswa ama-volts angu-5.0. Vala ukhiye.
• Bheka umdwebo wiring we-EGR bese uthola i-EGR voltage reference terminal kukhompyutha. Faka iphini noma isiqeshana sephepha kusixhumi esikukhompuyutha kuleli qophelo ukuhlola oxhumana naye emuva.
• Vula ukhiye. Uma ama-volts ama-5 akhona, ikhompyutha ilungile futhi inkinga ikuzintambo zokubophela uhlelo lwe-EGR. Uma kungekho voltage, khona-ke ikhompyutha ayilungile.

Iseluleko sokulungisa isekethe yokubuyisela kabusha igesi ngaphandle kokufaka ikhompyutha: Bheka umdwebo wiring bese uthola indawo yokugcina amandla okushisa okushisa okupholile. Bheka lesi siginali ngokhiye ofakiwe. Uma u-5 volt Ref. I-voltage ikhona, cisha ukhiye bese umaka amatheminali amabili osizo asetshenziswe kulezi zivivinyo. Khipha isixhumi sekhompiyutha, faka i-jumper wire phakathi kwalezi zikhonkwane ezimbili. Faka isixhumi futhi uhlelo lwe-EGR luzosebenza ngokujwayelekile ngaphandle kokufaka ikhompyutha esikhundleni.
