P0489 Exhaust Gas Recirculation (EGR) "A" - Circuit Low

Khodi Yovuta ya OBD-II - P0489 - Kufotokozera Zaukadaulo

Otsika chizindikiro mlingo mu dera ulamuliro wa utsi mpweya recirculation "A".

Code P0489 ndi generic powertrain code yokhudzana ndi kuwongolera kowonjezera kwa mpweya. Ngati khodiyi yasungidwa, zikutanthauza kuti Exhaust Gas Recirculation (EGR) "A" control circuit ikuwonetsa kutsika kwa magetsi.

Zizindikiro zokhudzana ndi P0489 ndi:

• P0405: chizindikiro chochepa mu gawo la sensa ya recirculation ya mpweya utsi "A"
• P0406: Mkulu wa siginecha mu gawo la sensa ya kubwereza kwa mpweya wotulutsa "A"
• P0409: Sensor ya Exhaust Gasi Recirculation "A" Dera

• P0488: EGR Throttle Position Control Range/Magwiridwe
• P0490: Kutulutsa kwa Gasi Kuwongolera Kuzungulira Kwambiri
• P2413: magwiridwe antchito a EGR

Kodi vuto la P0489 limatanthauza chiyani?

Iyi ndi nambala yofalitsira yomwe imatanthawuza kuti imakhudza mitundu yonse kuyambira 1996 mpaka mtsogolo. Komabe, njira zina zothetsera mavuto zimatha kusiyanasiyana ndi galimoto.

Zizindikiro zamavuto a injiniwa zimatanthawuza kusokonekera kwa makina otulutsa mpweya wotulutsa mpweya. Mwachindunji, mbali yamagetsi. Dongosolo la kutulutsa mpweya wotulutsa mpweya ndi gawo lofunikira la makina otulutsa magalimoto, ntchito yake ndikuletsa kupanga NOx (nitrogen oxides) m'masilinda.

EGR imayang'aniridwa ndi makina oyang'anira injini. Kompyutayo imatsegula kapena kutseka utsi womwe umabwezeretsanso kutengera kutengera katundu, kuthamanga komanso kutentha kuti pakhale kutentha kwamphamvu kwamphamvu. Pali zingwe ziwiri zamagetsi zamagetsi pa EGR zomwe kompyuta imagwiritsa ntchito kuti iyatse. Potentiometer imapezekanso mu utsi wamafuta oyendetsera mpweya, womwe umawonetsa malo a ndodo ya EGR (makina opangira omwe amatsegula ndikutseka ngalande).

Izi zikufanana kwambiri ndi kuzimitsa magetsi m'nyumba mwanu. Mukatsegula switch, kuwala kumawalako pamene magetsi akuwonjezeka. Makompyuta anu a injini samawona kusintha kwamagetsi ikayesa kutsegula kapena kutseka EGR, kuwonetsa kuti yakhala pamalo amodzi. Zizindikiro P0489 Exhaust Gas Recirculation Control Circuit "A" sikutanthauza kusintha kwamagetsi kochepa, kuwonetsa kuti EGR ikutsegula kapena kutseka. P0490 imafanana, koma izi zikutanthauza kuti kuzungulira kwake ndikokwera, osati kutsika.

Mafuta osasunthika amatha kupanga NOx pamagetsi otentha kwambiri amafuta. Dongosolo la EGR limayang'anira kuchuluka kwa mpweya wokwanira kubwereranso kuzambiri. Cholinga ndikuchepetsa mafuta omwe akubwera mokwanira kuti abweretse kutentha kwa mutu wam'munsi pansi pa NOx.

Kugwira ntchito kwa dongosolo la EGR ndikofunikira pazifukwa zambiri kuposa kupewa kwa NOx - kumapereka nthawi yolondola ya mphamvu zambiri popanda kugogoda, komanso kusakaniza kwamafuta ochepa kuti pakhale mafuta abwino.
