I-P0488 EGR Rotottle Position Control Range / Ukusebenza

Ikhodi Yenkinga ye-OBD-II - P0488 - Ishidi Ledatha

I-Exhaust Gas Recirculation Throttle Position Adjustment Range / Ukusebenza

Isho ukuthini ikhodi yenkinga P0488?

Le Generic Transmission / Engine DTC imvamisa isebenza ezinjinini zikadizili ezakhiwe ngemuva kuka-2004, kufaka phakathi kepha kungagcini kuzimoto ezithile zeFord, Dodge, GM, Mercedes, Mitsubishi, Nissan, Suzuki, neVW.

Le valve itholakala phakathi kokuphindaphindeka kokudla nesihlungi somoya, njengomzimba wempintsha. Isetshenziselwa ukudala i-vacuum encane ezodonsela amagesi okukhipha kokuphindaphindwayo kokudla.

Imodyuli yokulawula i-powertrain (PCM) itshela i-valve yokukhipha igesi (EGR) lapho ikhona. Le khodi ibheka amasiginali wamandla kagesi avela ku-EGR mpintsha wokulawula impempe ukuthola ukuthi alungile ngokuya ngokufakwa ku-PCM. Le khodi kungenzeka isethwe ngenxa yezinkinga zemishini noma zikagesi.

Izinyathelo zokuxazulula inkinga zingahluka ngokuya ngomkhiqizi, uhlobo lwe-EGR mpintsha ye-valve nemibala yocingo.

Izimpawu

Cishe ngeke uphawule noma yiziphi izimpawu lapho ikhodi yethulwa. Ikhodi iyagcinwa futhi ukukhanya kwenjini yesevisi kuyakhanya.

Izimpawu zekhodi yenjini engu-P0488 zingafaka:

• Ilambu Lenkomba Yokungasebenzi (MIL) likhanyisiwe
• Isikhathi eside kunokujwayelekile sokuvuselelwa kokuvuselelwa ngemuva kwesikhathi (kuthatha isikhathi eside ukuthi uhlelo lwe-exhaust lushise futhi lushise umusi onqwabelene ngaphakathi kwesiguquli se-DPF / catalytic)

Izimbangela zephutha P0488

Kunezimbangela ezimbalwa ezingaba khona zekhodi ye-P0488. Isizathu esivame kakhulu iziteshi zezinzwa ze-DPFE ezivalekile kanye namashaneli e-EGR. Ungase futhi uthole inzwa ye-MAP embi, inzwa ye-EGR, i-valve ye-EGR, noma i-EGR control solenoid. Ungase futhi uthole ulayini wokuhlanza ophukile noma izintambo zikagesi ezinephutha (noma izixhumi).

Izizathu ezingaba khona zokusetha le khodi:

• Vula ukujikeleza kwesiginali phakathi kwe-EGR mpintsha ye-valve ne-PCM
• I-voltage emfushane ekujikelezeni kwesiginali yegesi yokukhipha igesi.
• Okufushane phansi emjikelezweni wesiginali yegesi yokukhipha igesi.
• I-Exhaust gas recirculation throttle valve inesici - isifunda esifushane sangaphakathi
• I-PCM Yehlulekile - Akwenzeki

Izinqubo zokuxilonga nokulungisa

Iphuzu elihle lokuqala ngaso sonke isikhathi ukuhlola ama-bulletins ezinsizakalo zobuchwepheshe (i-TSB) yemoto yakho ethile. Inkinga yakho ingaba inkinga eyaziwa ngesilungisi esikhishwe ngumkhiqizi futhi ingakongela isikhathi nemali ngenkathi uxazulula inkinga.

Bese uthola i-valve yokulawula impintsha ye-EGR emotweni yakho ethile. Le valve itholakala phakathi kokuphindaphindeka kokudla kanye nesihlungi somoya, njengomzimba wempintsha. Uma usutholakele, hlola ngokubonakalayo izixhumi nezintambo. Bheka imihuzuko, izikhafu, izintambo eziveziwe, amamaki okushisa, noma ipulasitiki ebunjiwe. Nqamula izixhumi futhi uhlole ngokucophelela amatheminali (izingxenye zensimbi) ngaphakathi kwezixhumi. Bona ukuthi zibukeka zishisiwe noma zinombala oluhlaza okhombisa ukugqwala. Uma udinga ukuhlanza ama-terminals, sebenzisa i-electric contact cleaner kanye ne-plastic bristle brush. Vumela ukomisa nokufaka i-dielectric silicone grease lapho kuthinta amatheminali.

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

Uma ikhodi ye-P0488 ibuya, kuzodingeka sihlole i-valve ye-EGR mpintsha namasekhethi ahlobene. Imvamisa, izintambo ezi-3 noma ezi-4 zixhunywe ku-valve ye-EGR mpintsha. Nqamula i-harness kusuka ku-EGR mpintsha ye-valve. Sebenzisa i-digital volt ohmmeter (i-DVOM) ukuhlola umjikelezo wesiginali ye-EGR mpintsha yokulawula isigaxa (ucingo olubomvu ukuya kusiginali yesiginali ye-valve, ucingo olumnyama kumhlabathi omuhle). Uma ingekho i-volt engu-5 ku-valve, noma uma ubona ama-volts ayi-12 ku-valve, lungisa i-wiring kusuka ku-PCM iye ku-valve, noma i-PCM enephutha.

Uma kujwayelekile, qiniseka ukuthi unenhlabathi enhle ku-valve ye-EGR mpintsha. Xhuma isibani sokuhlola ku-12V battery positive (i-terminal ebomvu) bese uthinta omunye umkhawulo wesibani sokuhlola kusifunda somhlaba esiholela emhlabathini wesifunda se-valve we-EGR. Uma isibani sokuhlola singakhanyi, sikhombisa isifunda esingalungile. Uma ikhanyisa, shintsha izintambo zokubopha izintambo eziya ku-EGR mpintsha valve ukubona ukuthi isibani sokuhlola siyacwayiza yini, okukhombisa ukuxhumana okuphakathi.

Uma zonke izivivinyo zangaphambilini zidlula futhi uqhubeka nokuthola i-P0488, kungenzeka ikhombise i-valve elawula i-EGR mpintsha yokulawula, yize i-PCM ehlulekile ingakhishwa ngaphandle kuze kufakwe i-EGR mpintsha yokulawula impintsha.

IYIZINKANI IKHODI P0488?

Ikhodi P0488 ibucayi futhi uma ungenalo ulwazi oluningi futhi ungenawo amathuluzi afanele, kufanele ihlolwe uchwepheshe oqeqeshiwe.

YIKUPHI UKULUNGISA ONGALUNGISA IKHODI P0488?

Ngokuhamba kwesikhathi, i-carbon yakheka ngaphakathi enjinini, engabangela ukuvinjelwa nokuvinjelwa. Zama ukukhipha i-valve ye-EGR. Uma uhlelo lwe-EGR lungasebenzi ngomfutho we-vacuum kuphela, i-valve ye-EGR kufanele ishintshwe. Njalo lungisa amahhanisi avuliwe noma amafushane nezixhumi njengoba kudingeka bese uphinda uhlola. Uma uxilonga isistimu ye-EGR esebenzisa i-valve ye-EGR esemgqeni, sebenzisa isikena ngaso sonke isikhathi ukuze uvule i-EGR lapho injini isamile. Uma injini ingami, susa i-EGR enjinini, uyiphendule futhi uhlole ukusebenza kwayo. Uma i-valve ye-EGR inephutha, uzodinga ukuyishintsha, usethe kabusha ikhodi bese uzama futhi. Kodwa-ke, uma isebenza, susa i-valve ye-EGR enjinini bese uqala injini. Uma injini isebenza ngesivinini esijwayelekile, uyazi ukuthi uvale amaphaseji e-EGR.

AMAPHUTHA AVAMILE LAPHO KUHLOLWA IKHODI P0488

Abantu abaningi bazobona inkulumo ethi "valve EGR" futhi, bekholelwa ukuthi inkinga i-valve, izothatha indawo ye-valve ye-EGR. Lokhu ukumiselela okumba eqolo futhi cishe ngeke kuyilungise inkinga. I-valve ye-EGR ayivamile ukuba nenkinga.

IMIBONO ENGEZIWE UKUZE UQAPHELE IKHODI P0488

Izimoto eziningi ezindala zinezinkinga zesikhashana ngenxa yokucindezeleka isikhathi eside ekudluliseni. Kuyiqiniso ukuthi ikhodi ye-P0488 inzima ukuyixilonga nokuyilungisa, kodwa akunzima ukuyilungisa njengamanye amakhodi. Uma unquma ukuzenza ngokwakho, qiniseka ukuthi ucwaninga ukuthi ungayilungisa kanjani le nkinga futhi uthole imishini efanele yokuxilonga ngaphambi kokuba uqale. Inzuzo kachwepheshe oqeqeshiwe ukuthi uzoba nemishini yokuhlola nokuqinisekisa inkinga yakho. Zizwe ukhululekile ukuthintana nochwepheshe, ngisho noma kuwukuthola nje ukuthi ungayilungisa kanjani inkinga ngokwakho.

Udinga usizo olwengeziwe ngekhodi le-p0488?

Uma usadinga usizo nge-DTC P0488, thumela umbuzo kumazwana angezansi kwalesi sihloko.

QAPHELA. Lolu lwazi lunikezwa ngenhloso yokwaziswa kuphela. Akuhloselwe ukuthi isetshenziswe njengesincomo sokulungisa futhi asinacala nganoma yisiphi isenzo osithathayo kunoma iyiphi imoto. Yonke imininingwane ekulesi siza ivikelwe yi-copyright.
