Tsamba la deta la P0170 OBD-II

Fuel System Corrector Malfunction (Bank 1)

Kodi izi zikutanthauzanji?

Izi Diagnostic Trouble Code (DTC) ndi njira yolozera, zomwe zikutanthauza kuti imagwira ntchito pamagalimoto okhala ndi OBD-II. Ngakhale zambiri, njira zina zakukonzanso zimatha kusiyanasiyana kutengera mtundu / mtundu.

Khodi iyi imadziwika kwambiri pamtundu wina wamagalimoto kuposa ena. Ndawonjezerapo zambiri za Mercedes-Benz ndikulemba nkhaniyi chifukwa zikuwoneka kuti MB (ndi VW) ndizotheka kukhala ndi P0170 pamwamba palimodzi ndi ma misfire kapena ma trim code ena. P0170 amatanthauza kuti vuto lachitika mlengalenga pamakompyuta: kuchuluka kwamafuta.

Zikuwonetsanso kuti zoyatsira mafuta zafika pamalire owonjezerapo mafuta poyesera kulipirira chuma chenicheni kapena chowoneka kuti ndi cholemera. Mafuta a mafuta akafika pamalire ochepa, PCM (powertrain control module) imayika P0170 kuti iwonetse vuto kapena kulephera kwa mafuta. Pakhoza kukhalanso P0173 yonena za kulephera komweko, koma pamzere wachiwiri.

Zizindikiro za zolakwika P0170

Zizindikiro za vuto la P0170 zitha kuphatikiza:

• MIL (Nyali Yoyendetsa Chizindikiro)
• Yambani ndi kuima
• Mafuta osauka
• Utsi wakuda pa payipi yotulutsa
• Wobble / misfire pa ulesi kapena pakatundu

zifukwa

Zomwe zingayambitse zimaphatikizira kutuluka kwa zingalowe, kutuluka kwa mpweya kosayerekezeka. Mafuta omwe ali ndi mafuta ochulukirapo omwe amathira turbocharger (ngati ali ndi zida) Chojambulira cha O2 chomwe chingakhale cholakwika (Mercedes ingafune kusinthidwa ndi chida chofananira cha M-Benz). Kuwonongeka kwamafuta mu cholumikizira cha MAF kapena zolumikizira masensa a O2. Onaninso ma coil oyatsira, cam ndi sensors crank, ndi sensa yamafuta ngati ikudontha yomwe ingalole mafuta kulowa mu zingwe zazingwe. Chojambulira cholakwika cha MAF (MAF) (makamaka pa Mercedez-Benz ndi magalimoto ena aku Europe. Pali zovuta zambiri ndimasensa osankhidwa a MAF). Woyendetsa mafuta wamafuta owonongeka Atayikira mu ma valavu oyang'anira nthawi yamagetsi (Mercedes-Benz).

Dziwani: Kwa mitundu ina ya Mercedes-Benz, pamakhala chikumbukiro chantchito ya payipi yopumira yomwe ili pansi pochulukirapo. Fufuzani kutuluka / ming'alu ndikuyang'ana ma valve mu payipi. Valavu yowunika imangoyenda mbali imodzi.

Njira zothetsera P0170

Tiyenera kunena kuchokera pa bat kuti vuto lomwe limafala kwambiri ndi code iyi ndi sensa ya MAF kapena mita yolowera mphepo. Izi ndizowona makamaka kwa Mercedes-Benz, Volkswagen ndi magalimoto ena aku Europe. Panthawi yolemba, nthawi zambiri simukuwona code iyi ndi magalimoto aku America komanso magalimoto aku Asia, ndipo kunena zowona, sindikudziwa chifukwa chake. Zikuwoneka kuti lingaliro la PCM (Powertrain Control Module) logwiritsidwa ntchito ndi opanga magalimoto ena ku Europe kukhazikitsa DTC P0170 (kapena P0173) siligwiritsidwa ntchito ndi opanga magalimoto aku America. Ma code omwe amapezeka kwambiri ndi P0171, 0174, 0172, 0175, oyikidwa molingana ndi zolakwika zazing'ono zamagalimoto aku America. Palibe zambiri pazomwe tikukonzekera P0170 kapena P0173, koma zambiri zomwe zikupezeka zikuwoneka kuti ndizosafunikira pakukonzekera P0171,4,2 & 5. Ndikutsimikiza kuti pali chifukwa chake, koma sindingathe kuti aliyense anene ine chimene icho chiri. Kufanana pakati pawo kungakhale chifukwa chomwe sitimakonda kuwona nambala iyi pagalimoto zoweta. Ndizosafunikira chabe. Chifukwa chake, mwachidule, ngati muli ndi P0170, PCM yanu yazindikira kuti zoyatsira mafuta zafika pamalire awo ochepa. Kwenikweni, ndikuwonjezera mafuta kuyesa kubwezera zovuta, zenizeni kapena zodziwika.

Ngati muli ndi code iyi komanso mwayi wogwiritsa ntchito sikani, onani kuwerengera kwa gramu / gawo kuchokera pa sensa ya MAF. Kuwerenga kumasiyana mosiyanasiyana pagalimoto, chifukwa chake mumachita bwino. Ndikakamira ndi zomwe zingakhale zachilendo Mercedes (1.8L) popeza ali ndi vuto lalikulu. Yembekezerani kuti muwoneke pa 3.5-5 g / s (moyenera). Pa 2500 rpm yopanda katundu, iyenera kukhala pakati pa 9 ndi 12 g / s. Mumayeso amsewu a WOT (Wide Open Throttle), ayenera kukhala 90 g / s kapena kupitilira apo. Ngati sichikutchulidwa, m'malo mwake. Samalani ndi Ebay MAF. Nthawi zambiri sizigwira ntchito molingana ndi mafotokozedwe a OE. MAF ikayang'aniridwa ndipo mafuta salowa cholumikizira, yang'anani kuthamanga kwa mafuta ndikuonetsetsa kuti palibe zotuluka mkati kapena kunja kwa woyang'anira. Onetsetsani zotsekemera zonse ndikuonetsetsa kuti palibe zosweka, zosadulidwa, kapena zosowa. Fufuzani kutuluka kotsukira kuchokera kumapangidwe ochulukirapo komanso kupuma kwa payipi. Ngati injini ili ndi turbocharged, onetsetsani kuti ma hoses ali bwino komanso alibe zotuluka. Kutsika kwa ma turbo hoses kumatha kudzetsa chuma. Onaninso momwe payipi yopumira ya crankcase ilili pansi pochulukitsa komanso momwe valavu ya cheke ikugwirira ntchito. (Pazifukwa Ziti?) Ngati palibe zovuta ndi mafuta, MAF, kapena ma vacuum payipi, yang'anani zolumikizira za O2 kuti mulowetse mafuta. Chojambulira choipa cha O2 chitha kuyambitsa kachidindo ka P0170 kapena P0173. Konzani zomwe zimayambitsa mafuta ndikubwezeretsanso sensa yamafuta O2.

Kodi P0170

Mukufuna thandizo lina ndi nambala yanu ya p0170?

Ngati mukufunabe thandizo ndi DTC P0170, 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.
