P0490 Exhaust Gasi Recirculation (EGR) "A" Kudzora Circuit High

OBD-II Dambudziko Code - P0490 - Datasheet

Pedza Gasi Kudzora Kudzora Dunhu "A" Yakakwira

Ko dambudziko rekodhi P0490 rinorevei?

Iyi generic transmission kodhi zvinoreva kuti inovhara zvese zvinogadzira / mamodheru kubva 1996 zvichienda mberi. Nekudaro, matanho akasarudzika ekugadzirisa anogona kusiyana nemotokari kuenda kumotokari.

Aya makodhi ematambudziko einjini anoreva kusashanda mune exhaust gasi recirculation system. Kunyanya kunyanya, iyo yemagetsi chikamu. Iyo yekupedza gasi recirculation system chikamu chakakosha cheiyo mota exhaust system, iyo basa rekudzivirira kuumbwa kweinokuvadza NOx (nitrogen oxides) mumasilinda.

EGR inodzorwa neinjini manejimendi manejimendi. Iyo komputa inovhura kana kuvhara iyo yekuzadza gasi kudzokorodza sisitimu, zvinoenderana nemutoro, kumhanya uye tembiricha, kuitira kuchengetedza iyo chaiyo humburumbira musoro tembiricha. Kune mawaya maviri kune yemagetsi solenoid pane EGR iyo komputa inoshandisa kuimisa. Iyo potentiometer inowanikwawo mune yekudzimisa gasi yekudzokorora solenoid, iyo inoratidza chinzvimbo cheiyo EGR tsvimbo (iyo yekushandisa mashandiro ayo anovhura uye anovhara iyo duct).

Izvi zvakafanana nekudzikisira mwenje mumba mako. Paunoshandura switch, mwenje unowedzera kupenya sezvo magetsi achiwedzera. Yako injini komputa haina kuona chero magetsi shanduko painoyedza kuvhura kana kuvhara iyo EGR, zvichiratidza kuti yakanamatira mune imwechete nzvimbo. P0490 Exhaust Gesi Kuchenesa Kudzora Dunhu A zvinoreva kuti hapana shanduko yemagetsi, zvichiratidza kuti EGR iri kuvhura kana kuvhara. P0489 yakafanana chaizvo, asi zvinoreva dunhu rakadzika, kwete rakakwirira.

Unleaded mafuta anotanga kuumba NOx pakunyanyisa injini humburumbira tembiricha. Iyo EGR system inotungamira yakadzorwa huwandu hweanopedza gasi kudzokera kune yakawanda yekudyira. Chinangwa ndechekusanganisa musanganiswa wemafuta uri kuuya zvakakwana kuti uunze humburumbira musoro tembiricha pazasi peiyo panoumbwa NOx.

Kushanda kweEGR system kwakakosha kune zvikonzero zvakawanda kupfuura kudzivirira kweNOx - inopa nguva yakaringana yesimba rakawanda pasina kugogodza, uye musanganiswa wemafuta akaonda kuitira hupfumi hwemafuta huri nani.

Zviratidzo

Zviratidzo zvinosiyana zvichienderana nechinzvimbo cheiyo EGR tsono panguva yekundikana. Muzviitiko zvakawanda, iyo kodhi P0490 haina kutungamirwa nechero zviratidzo. Muridzi wemotokari ichaziviswa dambudziko neCheck Engine mwenje iri kuuya. Zvisinei, dzimwe mota dzinogona kumhanya zvisina tsarukano kana kunetsa kudzimisa. Varidzi vemotokari vanogona kune kuderera kwesimba kana kuderera kwekushandiswa kwemafuta.

• Injini yakaoma kwazvo inomhanya
• Tarisa injini mwenje iriko
• Kudonha hupfumi hwemafuta
• Kuderera musimba
• Hapana kutanga kana kunetsa kutanga kunoteverwa neyakaipisisa idle

Zvinogoneka Zvikonzero zveCode P0490

Kazhinji, yakavharwa EGR kana DPFE chiteshi imhosva yeP0490 kodhi.

Panogona zvakare kuve nepfupi kune bhatiri voltage kana kusashanda kweECU kuchikonzera iyi kodhi.

Zvikonzero zveiyi DTC zvinogona kusanganisira:

• Pfupi redunhu kusvika pasi
• Ipfupi redunhu kune bhatiri voltage
• Yakashata yekubatanidza ine yakasundidzirwa kunze mapini
• Ngura mune chinobatanidza
• Tsvina EGR tsono
• Inokanganisa chiutsi gasi kudzokorodza solenoid
• Zvakaipa EGR
• ECU inokanganisa kana komputa

Maitiro ekugadzirisa

Kana mota yako yafamba isingasviki 100,000 makiromita makumi masere, zvinokurudzirwa kuti uongorore warandi yako. Mota zhinji dzinotakura warandi ye80 kana 100,000 mamaira ekudzora. Chechipiri, enda pamhepo uye utarise ese akakodzera TSBs (technical Service Bulletins) ane hukama nemakodhi aya uye maitiro ekuagadzirisa.

Kuti uite izvi zvekuongorora maitiro, iwe unozoda zvishandiso zvinotevera:

• Volt / Ohmmeter
• Pedza gasi kudzokorora kubatana dhayagiramu
• Jumper
• Mapepa maviri emapepa kana kusona tsono

Vhura hood uye utange injini. Kana injini ikasashanda zvakanaka, bvisa ipulagi kubva kuESR system. Kana injini ikatsetseka, pini inonamira muEGR. Misa injini uye kutsiva EGR.

Tarisa pawaya yekubatanidza paEGR. Kune 5 waya, waya mbiri dzekunze dzinodyisa bhatiri voltage uye pasi. Idzo nhatu dzepakati waya i potentiometer iyo inoratidza kune komputa huwandu hwekuyerera kweEGR. Iyo yepakati terminal ndiyo 5V reference terminal.

Nyatsoongorora chinongedzo chemapini akabuda, ngura, kana hoko dzakakungwa. Wongorora wiring tambo yakanyatso chengetedza chero kuputira kana zvingangoita maseketi mapfupi. Tarisa waya dzakavhurika dzinogona kuvhura dunhu.

• Shandisa voltmeter kuyedza chero terminal inotungamira netambo tsvuku uye vhuna iyo nhema tambo. Batidza kiyi uye tsvaga gumi nemaviri volts uye ese maviri magumo ekupedzisira.
• Kana iwo magetsi asina kuratidzwa, saka pane tambo yakavhurika pakati peESGR system uye bhazi remoto. Kana gumi nemaviri volts achiratidzwa kune rimwe divi chete, iyo EGR system ine yemukati yakavhurika redunhu. Tsiva EGR.
• Dzinga chinongedzo kubva pakuneta gasi kudzokorodza sisitimu uye nekiyi iri uye injini yabviswa, tarisa vese vekunze vanobata simba. Nyora pasi kuti ndeipi ine gumi nemaviri volts uye kutsiva chinongedzo.
• Isa chidimbu chebepa pane iyo yekupedzisira lug iyo isina kupihwa simba, iyi ndiyo yepasi lug. Batanidza jumper paperclip. Pasi pejumper. "Dzvanya" inonzwika kana iyo EGR yaitwa. Dzinga tambo yepasi uye tanga injini. Ground waya zvakare uye panguva ino injini inomhanya zvine mutsindo kana EGR ikapihwa simba uye yakapfava kana pasi yabviswa.
• Kana iyo EGR sisitimu yashandiswa uye injini inotanga kushanda nguva nenguva, saka iyo EGR system iri muhurongwa, dambudziko ndere magetsi. Kana zvisiri, misa injini uye kutsiva iyo EGR.
• Tarisa nzvimbo yekupedzisira yeiyo chiutsi gasi recirculation chinongedzo. Vhura kiyi. Kana iyo komputa iri kushanda nemazvo, 5.0 volts inoratidzwa. Dzima kiyi.
• Tarisa kune EGR wiring dhayagiramu uye tsvaga iyo EGR voltage reference terminal pakombuta. Isa pini kana pepa clip mune chinobatanidza pakombuta panguva ino kuti utarise unodzoka kumashure.
• Vhura kiyi. Kana ma5 volts aripo, komputa yakanaka uye dambudziko riri mune wiring sunga kune EGR system. Kana pasina magetsi, ipapo komputa inokanganisa.

Zano rekugadzirisa iyo yekudzimisa gasi kudzokorodza dunhu pasina kutsiva komputa: Tarisa pane wiring dhayagiramu uye tsvaga iyo inotonhorera tembiricha reti voltage terminal. Tarisa ichi chinongedzo nekiyi inosanganisirwa. Kana iyo 5 volt Ref. Voltage iripo, bvisa kiyi uye mucherechedzo matemu maviri ekutsigira anoshandiswa mune izvi bvunzo. Dhonza kunze kwekomputa chinobatanidza, solder jumper waya pakati pezvipini zviviri izvi. Isa chinongedzo uye iyo EGR system ichashanda zvakajairika pasina kutsiva komputa.

Zvakajairwa Kukanganisa Pakuongororwa Code P0490

Chikanganiso chinowanzoitika kana uchitsvaga chikonzero chekodhi P0490 ndeye otomatiki kutsiva EGR vharafu. Ichi chikamu hachiputsike kakawanda sevamwe vazhinji. zvikamu zveEGR system.

Kodhi yeP0490 yakakomba zvakadii?

Nekuti kuunganidzwa kweNOx mumasilinda emotokari kunogona kukuvadza zvakanyanya, kuvapo kwe Code P0490 yakakomba. EGR inoshanda nemazvo zvakare chinhu chakakosha kuitira hupfumi hwakanaka hwemafuta. Kugadziriswa uku kunofanirwa kugadziriswa nekukurumidza.

Ndezvipi zvinogadzirisa zvinogona kugadzirisa kodhi P0490?

Kuita chokwadi chekuti zvikamu zvemagetsi hazvina mhosva yekuchengetedza

Code P0490, mechanic ine akati wandei ekugadzirisa sarudzo:

• Shandisa scanner kutarisa EGR basa uye nemaoko enzanisa ruzivo ne zvinodiwa nemugadziri.

• Tarisa uye gadzirisa EGR valve , kudzora solenoid, sensor kana DPFE sensor. zvakakodzera.

• Bvisa tambo yevacuum uye nemaoko shandisa vacuum kune EGR valve kuti uone kushanda.

• Bvisa EGR valve uye uichenese yekuvhara.
• Ita shuwa kuti komputa iri kushanda nemazvo woitsiva kana zvichidikanwa.
• Tarisa zvese zvinongedzo uye wiring zvePCM uye kugadzirisa kana kutsiva sezvinodiwa.

Mushure mekugadzirisa kwega kwega kwakadaro, code inofanira kucheneswa uye hurongwa hunofanira kuva rechecked. Kunyanya kugadzirisa kuchaiswa mucherechedzo murunyoro, zvichava nyore nyanzvi kuderedza chikonzero chechokwadi chekodhi P0490.

Mamwe makomendi ekufunga nezve kodhi P0490

Kana kodhi P0490 inowanikwa pamotokari ine isingasviki 100 mamaira, tarisa Warranty yemugadziri kana Dealer's Warranty. Iyo EGR system inowanzovharwa pasi pewaranti yakajairwa, uye mutengo wekutsiva kana kugadzirisa unogona kuvharwa garandi.
