I-P0489 Exhaust Gas Recirculation (EGR) System “A” - Isiyingi Iphansi

Ikhodi Yenkinga ye-OBD-II - P0489 - Ishidi Ledatha

Izinga lesignali eliphansi kumjikelezo wokulawula we-exhaust gas recirculation "A".

I-Code P0489 iyikhodi ye-generic powertrain ehlobene nokulawula ukukhishwa okungeziwe. Uma le khodi igciniwe, kusho ukuthi i-Exhaust Gas Recirculation (EGR) "A" control circuit ibika i-voltage ephansi yokugeleza.

Amakhodi ahlobene ne-P0489 afaka:

• I-P0405: Isignali ephansi kumjikelezo wenzwa yokuphindaphinda kwamagesi okukhipha "A"
• I-P0406: Izinga lesignali ephakeme kumjikelezo wenzwa yokuphindaphinda kwegesi yokukhipha "A"
• I-P0409: I-Exhaust Gas Recirculation Sensor "A" Circuit
• I-P0487: I-EGR Throttle Position Control Circuit
• I-P0488: I-EGR Throttle Position Control Range/Ukusebenza
• I-P0490: I-Exhaust Gas Recirculation Control Circuit High
• I-P2413: Ukusebenza kwesistimu ye-EGR

Isho ukuthini ikhodi yenkinga P0489?

Le yikhodi yokudlulisela ejwayelekile okusho ukuthi ihlanganisa konke ukwenziwa / amamodeli kusuka ngo-1996 kuye phambili. Noma kunjalo, izinyathelo ezithile zokuxazulula inkinga zingahluka kusuka emotweni kuya emotweni.

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 P0489 Exhaust Gas Recirculation Control Circuit "A" asisho ukushintsha kwamandla aphansi, okukhombisa ukuthi i-EGR iyavula noma iyavala. I-P0490 iyafana ngokuyisisekelo, kepha lokho kusho ukuthi iluphu iphezulu, hhayi phansi.

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

• Kwehliswe ukonga kukaphethiloli wezimoto kukonke
• Ukwehla kwamandla emoto
• Imoto kungase kube nzima ukuyiqalisa noma ukungayiqali nhlobo.
• Umbhobho wemoto ungase ube mnyama ngokumnyama.
• Imoto ingase ingabonisi zimpawu nhlobo ngaphandle kwekhodi egciniwe.

Izimbangela ezingenzeka P0489

Izinqubo zokulungisa

Uma imoto yakho inamamayela angaphansi kuka-100,000, kunconywa ukuthi ubuyekeze iwaranti yakho. Izimoto eziningi ziqinisekiswa ngamamayela ayi-100,000 noma ayizinkulungwane eziyi-150-200 zokulawula ukungcola. Okwesibili, ngena ku-inthanethi futhi uhlole wonke ama-TSB afanelekile (Imininingwane Yesevisi Yobuchwepheshe) ahlobene nalawa makhodi nokulungisa kwawo.

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-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.

Amaphutha Avamile Lapho Uhlonza Ikhodi P0489

I-valve ye-EGR iyingxenye ebizayo yokufaka esikhundleni, futhi ngokuvamile lapho ikhodi ye-P0489 ivela, abaningi bayishintsha ngokushesha kunokuba bahlole ngokugcwele inkinga, engase imane ilimele izintambo noma i-gasket eshile.

Ibucayi kangakanani ikhodi ye-P0489?

Njengoba ukushayela okuphephile kwemoto kungafanele kuthintwe amaphutha agcina ikhodi ye-P0489, kodwa imoto ingakhiqiza izikhithi eziyingozi kakhulu, le khodi ibhekwa njengekhodi enamandla amakhulu. Uma le khodi ibonakala, kunconywa ukuba ngokushesha uthathe imoto esikhungweni sesevisi sendawo noma umakhenikha ukuze ilungiswe futhi ixilongwe.

Yiziphi izilungiso ezingalungisa ikhodi P0489?

Ukulungiswa okuningana kungalungisa ikhodi yenkinga ye-P0489 futhi kufaka:

• Lungisa noma shintsha izintambo ezilimele noma ezingaqinile, izixhumi namahhanisi.
• Lungisa noma shintsha noma iyiphi eyonakele noma ephukile futhi evuzayo ama-vacuum hoses kanye nemigqa.
• Lungisa noma ubuyisele okonakele noma okungalungile I-EGR yokulawula i-solenoid.
• Ukukhipha ikhabhoni kuvale amaphaseji e-EGR
• Sula wonke amakhodi, hlola imoto bese uskena kabusha ukuze ubone ukuthi akhona yini amakhodi aphinde avele.
• Faka esikhundleni eyonakele noma enesici I-valve ye-EGR
