P0102 Low MAF Dera

Kufotokozera zaukadaulo za cholakwika P0102

Sensa yothamanga kwambiri ya mpweya (yomwe zoyamba zake zimayimira mawu akuti "mass air flow)" adapangidwa kuti aziyesa kuchuluka kwa mpweya ndi kachulukidwe ka mpweya wolowa mu injini, ndipo sensa iyi imatha kukhazikitsidwa mwachindunji patope yotengera mpweya wa injini.

Sensa iyi ya misala ya air flow imangokhala ndi udindo woyeza kachigawo kakang'ono ka mpweya ukubwera, ntchito yake ndikutenga mtengo uwu ndikuwerengera kuchuluka kwa mpweya womwe ukubwera, ndipo ntchito ya PCM ndiyo kugwiritsa ntchito kuwerenga uku pamodzi ndi zina. khazikitsani magawo. kugwiritsa ntchito sensa kuti muwonetsetse mafuta oyenera nthawi zonsekotero kuti palibe kutaya mphamvu mu galimoto kapena injini.

Ngati sensa ya misa ya mpweya ili yolakwika, code ya OBDII P0102 idzawala.

Kodi P0102 imatanthauza chiyani?

Izi Kuzindikira Mavuto Code (DTC) ndi njira yotumizira, zomwe zikutanthauza kuti imagwira ntchito pamagalimoto okhala ndi OBD-II omwe ali ndi sensa ya MAF. Mtunduwu umaphatikizapo, koma suli malire, Toyota, Infiniti, Nissan, Jaguar, Audi, Mercedes, Dodge, Hyundai, Chevy, Ford, ndi zina zambiri.

The mass air flow (MAF) sensor ndi sensa yomwe ili mu injini yagalimoto yotengera mpweya pambuyo pa fyuluta ya mpweya ndipo imagwiritsidwa ntchito kuyeza kuchuluka ndi kuchuluka kwa mpweya womwe umakokedwa mu injini. The mass air flow sensor palokha imangoyesa gawo la mpweya wolowa, ndipo mtengo uwu umagwiritsidwa ntchito powerengera kuchuluka kwa mpweya wolowa ndi kuchuluka kwake.

Powertrain control module (PCM) imagwiritsa ntchito kuwerenga uku molumikizana ndi magawo ena amagetsi kuti zitsimikizire kuti pamafunika mafuta oyenera nthawi zonse kuti akhale ndi mphamvu yokwanira komanso mafuta.

Izi Diagnostic Trouble Code (DTC) P0102 zimatanthauza kuti chizindikiro chotsika chimapezeka mu sensa kapena dera lama misa. PCM imazindikira kuti chizindikiro chenicheni cha MAF sensor frequency sichikhala munthawi yofananira yamtengo wowerengera wa MAF.

Zindikirani. Masensa ena a MAF amakhalanso ndi mawonekedwe otenthetsera mpweya, womwe ndi mtengo winanso womwe PCM imagwiritsa ntchito makina moyenera.

Zizindikiro zoyandikana kwambiri za dera la MAF zimaphatikizapo P0100, P0101, P0103, ndi P0104.

Chithunzi cha masensa otulutsa mpweya wambiri (kutulutsa kwamlengalenga):

Kodi zizindikiro za P0102 ndi ziti?

Zizindikiro za chikhombo cha P0102 zitha kuphatikizira izi:

• Nyali Yazizindikiro Zosagwira (MIL) yowunikiridwa (yomwe imadziwikanso kuti nyali yochenjeza ya injini)
• Injini yoyendetsa pafupifupi
• Utsi wakuda kuchokera ku chitoliro cha utsi
• Kuyimilira
• Injini imayamba molimbika kapena pakhoma poyambira
• Zizindikiro zina zowongolera kapena osakhala nazo
• Kumverera roughness ndi otsika fluidity mu injini.
• Anamamatira poyambitsa injini, zomwe zingayambitse kuzimitsa basi.
• Kuvuta kuyendetsa.

Zifukwa zotani?

Zomwe zingayambitse DTC iyi ingaphatikizepo:

• Choyipa kapena chonyansa MAF sensa
• Choyipa cholakwika cha MAF
• Kulowetsa mpweya
• MAF sensor wiring harness kapena wiring vuto (lotseguka, dera lalifupi, kuvala, kulumikizana koyipa, ndi zina zambiri)

Dziwani kuti ma code ena atha kupezeka ngati muli ndi P0102. Mutha kukhala ndi ma misfire kapena ma code a O2, chifukwa chake ndikofunikira kuti mukhale ndi "chithunzi chachikulu" cha momwe makina amagwirira ntchito limodzi ndikukhudzirana akamazindikira.

Kodi ndingatani kuti ndipeze ndikukonzekera Engine Code P0102?

• Yang'anirani makina onse a MAF ndi zolumikizira kuti muwonetsetse kuti ali olimba, osaduka, osweka, oyendetsedwa pafupi kwambiri ndi mawaya oyatsira / ma coil, ma relays, ma injini, ndi zina zambiri.
• Yang'anirani zowoneka ngati kutuluka kwa mpweya m'dongosolo lolowetsa mpweya.
• Poyang'ana * mosamala * yang'anani mawaya a tepi a MAF (MAF) kapena tepi kuti muwone zonyansa monga dothi, fumbi, mafuta, ndi zina zambiri.
• Ngati fyuluta ya mpweya ndi yakuda, ikani m'malo mwake ndi fyuluta yatsopano yoyambira kwa ogulitsa anu.
• Sambani MAF bwino ndi MAF yoyeretsa kutsitsi, nthawi zambiri njira yabwino yoyezera / kukonza.
• Ngati pali thumba pantchito yolowetsa mpweya, onetsetsani kuti ndi yoyera (makamaka VW).
• Kutayika kwa makina pa MAP sensor kumatha kuyambitsa DTC iyi.
• Kutulutsa kotsika kocheperako kudzera mu bowo la sensa kumatha kuyambitsa DTC iyi kuti izikhala paulesi kapena pakusintha. Fufuzani ngati zingalowe m'malo othamangitsira pansi pa MAF sensa.
• Gwiritsani ntchito chida chowunikira kuti muwone momwe nthawi yeniyeni ya MAF imagwirira ntchito, masensa a O2, ndi zina zambiri.
• Fufuzani Technical Service Bulletins (TSB) pazomwe mungapangire / mtundu wamavuto omwe amadziwika ndi galimoto yanu.
• Anmospheric Pressure (BARO), yomwe imagwiritsidwa ntchito kuwerengera MAF yomwe idanenedweratu, idayamba kutengera sensa ya MAP pomwe kiyi ili.
• Kulimbana kwakukulu pamtunda wapansi wa MAP sensor kumatha kuyika DTC iyi.

Ngati mukufunikiradi m'malo mwa MAF sensa, timalimbikitsa kuti mugwiritse ntchito chojambulira cha OEM choyambirira kuchokera kwa wopanga m'malo mogula zina.

Chidziwitso: Kugwiritsa ntchito fyuluta yamafuta yomwe ingagwiritsidwenso ntchito kumatha kuyambitsa nambala iyi ngati yasungunuka kwambiri. Mafuta amatha kulowa pama waya kapena kanema wocheperako mkati mwa sensa ya MAF ndikuipitsa. Muzochitika izi, gwiritsani ntchito ngati kutsuka MAF kuyeretsa kutsuka MAF. Sitikulimbikitsa kugwiritsa ntchito zosefera zamafuta.

Kukonza injini P0102 kodi

Mukufuna thandizo lina ndi nambala yanu ya p0102?

Ngati mukufunabe thandizo ndi DTC P0102, lembani funso mu ndemanga pansipa pamutuwu.

ZINDIKIRANI. Izi zimaperekedwa kuti zidziwitse zokha. Sikuti tizigwiritsa ntchito ngati malingaliro okonzanso ndipo sitili ndi udindo pazomwe mungachite pagalimoto iliyonse. Zomwe zili patsamba lino ndizotetezedwa ndi zovomerezeka.
