MAP/MAF - Kulumikizana kwa Throttle Position

Kodi cholakwika 0068 chimatanthauza chiyani?

Code Yovutikira Kuzindikira (DTC) ndi nambala yotumizira. Imawerengedwa kuti ndiyaponseponse momwe imagwirira ntchito popanga mitundu yonse yamagalimoto (1996 ndi atsopano), ngakhale njira zowongolera zingasiyane pang'ono kutengera mtunduwo.

Khodi yolakwika yonse P0068 amatanthauza vuto la kuwongolera injini. Pali kusiyana pakati pa masensa apakompyuta pakati pamavuto amlengalenga omwe amalowa munthawi zambiri.

PCM imadalira masensa atatu kuti iwonetse voliyumu ya mpweya kuti iwerenge maukadaulo amafuta ndi nthawi. Masensawa amaphatikizira sensa yotulutsa mpweya wambiri, malo othamangitsira mawonekedwe, komanso mawonekedwe amtundu wamagetsi (MAP). Pali masensa ambiri pa injini, koma atatu amalumikizidwa ndi nambala iyi.

The mass air flow sensor ili pakati pa air cleaner ndi throttle body. Ntchito yake ndikuwonetsa kuchuluka kwa mpweya womwe ukudutsa mu thupi la throttle. Kuti muchite izi, kachidutswa kakang'ono ka waya wokaniza wokhuthala ngati tsitsi amakokedwa kudzera mu cholowera cha sensa.

Kompyutayi imagwiritsa ntchito magetsi pama waya awa kuti awutenthe mpaka kutentha komwe kudakonzedweratu. Momwe mpweya ukuwonjezeka, pamafunika ma voliyumu ambiri kuti kutentha kuzikhala. Komanso, voliyumu ya mpweya ikamachepa, pamafunika magetsi ochepa. Kompyutayo imazindikira mphamvu imeneyi ngati chisonyezo cha kuchuluka kwa mpweya.

Chojambulira chazakudya chimakhazikika mbali yina yokhotakhota mthupi lopumira. Mukatseka, valavu yampweya imalepheretsa mpweya kulowa mu injini. Mpweya wofunikiratu umadutsa valavu yampweya pogwiritsa ntchito mota wothamanga.

Mitundu yambiri yamagalimoto yamtsogolo imagwiritsa ntchito bolodi lamkati lam'mwamba pamwamba pa cholembera. Chophimbacho chikakhumudwa, kachipangizo kamene kamangotumizidwa kamatumiza magetsi ku magetsi, omwe amayendetsa kutsegula kwa valavu.

Pogwira ntchito, throttle position sensor sichinthu choposa rheostat. Pamene throttle imatsekedwa popanda ntchito, throttle position sensor imalembetsa pafupi kwambiri ndi 0.5 volts, ndipo ikatsegulidwa, monga panthawi yothamanga, mphamvuyi imakwera pafupifupi 5 volts. Kusintha kuchokera ku 0.5 mpaka 5 volts kuyenera kukhala kosalala kwambiri. Kompyuta ya injini imazindikira kuwonjezeka kwa magetsi ngati chizindikiro chosonyeza kuchuluka kwa mpweya ndi liwiro lotsegula.

Manifold Absolute Pressure (MAP) amatenga mbali ziwiri pantchitoyi. Imadziwika ndi kupsinjika kochulukirapo, komwe kumakonzedwa chifukwa cha kutentha kwa mpweya chifukwa cha kutentha, chinyezi komanso kutalika. Imalumikizidwanso ndikudya kosiyanasiyana kudzera payipi. Valavu ya fulumizitsa ikatseguka modzidzimutsa, kuthamanga kambiri kumatsika mwadzidzidzi ndikudzukanso pamene mpweya ukuwonjezeka.

Makompyuta oyang'anira injini amafunikira masensa onse atatuwa kuti adziwe molondola nthawi yotsegulira jakisoni ndi kuchuluka kwa nthawi yoyatsira kuti mafuta azikhala 14.5 / 1. pangani zolondola ndikuyika DTC P0068.
