P0489 Exhaust Gasi Recirculation (EGR) System "A" - Circuit Low

OBD-II Dambudziko Code - P0489 - Datasheet

Yakaderera chiratidzo nhanho mukudzora dunhu re exhaust gasi recirculation "A".

Code P0489 ndeye generic powertrain kodhi ine chekuita nekuwedzera emission control. Kana iyi kodhi yakachengetwa, zvinoreva kuti Exhaust Gasi Recirculation (EGR) "A" control circuit iri kuudza yakaderera kuyerera voltage.

Makodhi ane hukama neP0489 anosanganisira:

• P0405: Chiratidzo chakaderera mudenderedzwa re sensor yekudzokorodza kweanopedza gasi "A"
• P0406: Yakakwira chiratidzo nhanho mudunhu reiyo sensor yekudzokorodza kweanopedza gasi "A"
• P0409: Exhaust Gasi Recirculation Sensor "A" Circuit
• P0487: EGR Throttle Position Control Circuit
• P0488: EGR Throttle Position Control Range/Performance
• P0490: Exhaust Gasi Recirculation Control Circuit High
• P2413: EGR system performance

Ko dambudziko rekodhi P0489 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 nekudzikisa 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. Makodhi P0489 Exhaust Gesi Kudzokorodza Kudzora Dunhu "A" zvinoreva kuti hapana yakaderera magetsi shanduko, zvichiratidza kuti EGR iri kuvhura kana kuvhara. P0490 yakafanana chaizvo, asi izvo zvinoreva kuti chiuno chakakwirira, kwete pasi.

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.

• Injini yakaoma kwazvo inomhanya
• Tarisa injini mwenje iriko
• Kudonha hupfumi hwemafuta
• Kuderera musimba
• Hapana kutanga kana kunetsa kutanga kunoteverwa neyakaipisisa idle
• Yambiro kana cheki mwenje weinjini inogona kuuya
• Injini inogona kuita rough kana kushata pakusaita basa
• Yakaderedzwa huwandu hwemafuta emotokari
• Kudonha kwemagetsi emotokari
• Motokari inogona kunetsa kuimisa kana kusatomboimutsa.
• Exhaust yemotokari inogona kunge yakasviba.
• Motokari inogona kusaratidza chero zviratidzo zvachose kunze kwekodhi yakachengetwa.

Zvinogoneka Zvinokonzera P0489

Zvikonzero zveiyi DTC zvinogona kusanganisira:

• Pfupi redunhu kusvika pasi

Maitiro ekugadzirisa

Kana mota yako iine isingasviki 100,000 mamaira, zvinokurudzirwa kuti uongorore waranti yako. Mota zhinji dzakavimbiswa 100,000 kana 150-200 zviuru zvemamaira yekudzora kuburitsa. Chechipiri, enda online uye tarisa ese akakodzera maTSB (Technical Service Bulletins) ane chekuita nemakodhi aya uye kugadzirisa kwawo.

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 P0489

EGR valve chinhu chinodhura chinotsiva, uye kazhinji kana kodhi yeP0489 ichionekwa, vazhinji vanokurumidza kuitsiva pane kunyatsoongorora dambudziko, iro rinogona kungokuvadzwa wiring kana gasket rakatsva.

Kodhi yeP0489 yakakomba zvakadii?

Sezvo kutyaira kwakachengeteka kwemotokari kusingafanirwe kukanganiswa nezvikanganiso zvinochengeta kodhi yeP0489, asi mota inogona kuburitsa zvinokuvadza zvinoburitsa, iyi kodhi inoonekwa seyakakomba kodhi. Kana iyi kodhi yaonekwa, zvinokurudzirwa kuti uende nemotokari kunzvimbo yemunharaunda yebasa kana mechanic kuti igadziriswe uye kuongororwa.

Ndezvipi zvinogadzirisa zvinogona kugadzirisa kodhi P0489?

Kugadzirisa kwakawanda kunogona kugadzirisa iyo P0489 dambudziko kodhi uye inosanganisira:

• Gadzirisa kana kutsiva yakakuvadzwa kana yakasununguka wiring, zvinobatanidza, uye harnesses.
• Gadzirisa kana kutsiva chero yakakuvara kana yakaputsika uye inodonha vacuum hoses uye mitsetse.
• Gadzirisa kana kutsiva yakakuvara kana yakaremara EGR kudzora solenoid.
• Carbon clearing yakavharira EGR ndima
• Bvisa makodhi ese, edza mota uye tarisazve kuti uone kana paine macode anobuda zvakare.
• Tsiva yakakuvara kana kuti yakaremara EGR valve
