I-P0487 Isifunda esivulekile sokulawulwa kwe-valve mpintsha yohlelo lokukhipha igesi qeda

Ikhodi Yenkinga ye-OBD-II - P0487 - Ishidi Ledatha

I-P0487 - I-Exhaust Gas Recirculation (EGR) "A" I-Throttle Control Circuit Open

Ikhodi P0487 ikhombisa ukungasebenzi kahle ohlelweni lwe-exhaust gas recirculation (EGR). Le khodi ingase ibe khona kanye ne-P0409.

Isho ukuthini ikhodi yenkinga P0487?

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 amasignali wamandla kagesi avela ku-EGR mpintsha wokulawula impempe ukuthola ukuthi alungile ngokuya ngokufakwa ku-PCM. Le khodi ikwazisa ngokungasebenzi kahle kwesekethe kagesi.

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

Izimpawu

Kunezimpawu ezimbalwa kakhulu ezihlotshaniswa nekhodi ye-P0487 ngaphandle kwesibani se-Check Engine esikhanyisiwe. Kodwa-ke, abanye abashayeli bangase baqaphele ukusetshenziswa kukaphethiloli okuncishisiwe, ukukhuphuka kwejubane okuguquguqukayo, nokusebenza kwenjini okungelula kunokuvamile.

Izimpawu zekhodi yenjini engu-P0487 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 ezingenzeka zeKhodi P0487

Imvamisa isizathu sokufaka le khodi sithi:

• 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
• Amaphaseji avaliwe noma avinjiwe ku-valve ye-EGR
• Ukwehluleka kwe-valve ye-EGR
• Iphutha Inzwa ye-MAP
• I-solenoid engalungile yokulawula i-EGR
• yonakele noma umugqa we-vacuum ophukile
• Izinzwa ze-DPFE ezivinjiwe (ikakhulukazi ezimotweni zakwaFord)

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-P0487 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-P0487, kungenzeka ikhombise i-valve elawula i-EGR mpintsha yokulawula, yize i-PCM ehlulekile ingakhishwa ngaphandle kuze kufakwe i-EGR mpintsha yokulawula impintsha.

Amaphutha Avamile Lapho Uhlonza Ikhodi P0487

Iphutha elilodwa elivame kakhulu ekuxilongeni ikhodi engu-P0487 ukucabanga ngokushesha ukuthi inkinga i-valve ye-EGR. Nakuba kuvamile ukuthi i-valve ngokwayo ihluleke, empeleni ngokuvamile kuba yinkinga ngomugqa we-vacuum owonakele noma i-solenoid engalungile. Ukushintsha i-valve ngeke nje kulungise inkinga, kodwa lezi zingxenye empeleni zibiza kakhulu kunezinye eziningi zokulungisa.

Ibucayi kangakanani ikhodi ye-P0487?

Ikhodi P0487 ingase ingalithinti kakhulu ikhono lakho lokushayela, kodwa ingaba yinkinga. Kuzophinde kuvimbele imoto yakho ukuthi iphumelele izivivinyo zokungcola futhi kufanele ilungiswe ngokushesha okukhulu.

Yiziphi izilungiso ezingalungisa ikhodi P0487?

Inani lokulungiswa okungenzeka lisetshenziswe ukulungisa ikhodi P0487, kuhlanganise nalokhu okulandelayo:

• Ukushintshwa kwemigqa yevacuum eyonakele
• Ukushintsha i-solenoid ehlulekile
• Ukufaka esikhundleni I-valve ye-EGR
• Ukuhlanza isiteshi se-EGR

Amazwana engeziwe okufanele acatshangelwe mayelana nekhodi P0487

Isistimu yokujikeleza kabusha kwegesi ephumayo yemoto yakho iyingxenye ebalulekile yakho kokubili isistimu yemoto yakho kanye nesistimu kaphethiloli yemoto yakho. Amagesi akhipha umoya kufanele ashiswe kabusha ukuze kuthuthukiswe ukonga kukaphethiloli futhi kuncishiswe inani lentuthu ekhishelwa emkhathini.
