Kunyumba »Mauthenga P2700-P2799» P2768

Mapepala a OBD-II DTC

Kulephera kwa sensa yoyendera "B" yolowetsa liwiro / chopangira mphamvu

Kodi izi zikutanthauzanji?

Izi Diagnostic Trouble Code (DTC) ndi njira yotumizira, zomwe zikutanthauza kuti imagwira ntchito pagalimoto zonse kuyambira 1996 (Ford, Honda, Mazda, Mercedes, VW, etc.). Ngakhale zambiri, njira zina zakukonzanso zimatha kusiyanasiyana kutengera mtundu / mtundu.

Mukalandira DTC P2768, zikuwoneka kuti chifukwa powertrain control module (PCM) yapeza kulowetsa kwamagetsi kosakhazikika kuchokera kuzowonjezera (kapena chopangira mphamvu) dera loyendetsa liwiro lotchedwa "B". Ngakhale masensa olowera ndi ma turbo othamanga amafanana chimodzimodzi ndipo amatumikiranso cholinga chomwecho, matchulidwe amawu amasiyana ndi wopanga.

Nthawi zambiri, cholowera / chopangira mphamvu liwiro limakhala lamagetsi yamagetsi yamagetsi yamagetsi itatu yomwe imagwiritsidwa ntchito poyang'anira liwiro la polowera mu gearbox pamphindi (rpm). Sensulo nthawi zambiri imakhala pafupi ndi kumbuyo kwa belu (pa shaft yolowera) ndipo imayikidwa ndi bolt / stud kapena yolumikizidwa molunjika munyumba yotumizira.

Shaft yayikulu (kapena yolowetsera) yotumizirayo imalumikizidwa kwathunthu ndi gudumu lamagiya oyendetsera kapena malo opangidwira mwapadera. Injini yoyendetsa ikadutsa rpm kupita kufalikirako, shaft yolowetsera (kapena jet wheel) imayenda pafupi kumapeto kwa sensa. Shaft shaft (kapena gudumu lamagetsi) imamaliza bwino magetsi / magetsi amagetsi okhala ndi sensa. Njira yamagetsi imapangidwa pomwe dera limasokonezedwa ndi zigawo zopindika (kapena notched) zomwe zimadutsa sensa. Dera limazindikiridwa ndi PCM ngati mawonekedwe amawu, omwe amapangidwa kuti azimasulira ngati kulowetsa mphamvu yamagetsi / liwiro la chopangira mphamvu.

Kutumiza kwa liwiro, liwiro lolowetsa liwiro / liwiro la chopangira mphamvu, kuthamanga kwa injini, kupumira, kuchuluka kwa injini, ndi zinthu zina zimafaniziridwa ndikuwerengedwa kuti mudziwe liwiro lolowera / chopangira mphamvu. P2768 code isungidwa (ndipo nyali yosagwira bwino ingawunikire) ngati ma RPM / RPM kapena ma voliyumu azigawo sangakhale olondola mkati mwa nthawi inayake.

P2768 imawonetsa kulowererapo kwapakati pamagetsi oyimitsira yolowetsa / chopangira mphamvu.

Zizindikiro

Zizindikiro za chikhombo cha P2768 zitha kuphatikizira izi:

• Ntchito yosakhazikika ya speedometer (odometer)
• Kutumiza sikusuntha moyenera
• Speedometer ndi / kapena odometer sizigwira ntchito konse
• Malo osunthira otumizira amakhala osasintha kapena ovuta
• Kuchepetsa mafuta

zifukwa

Zifukwa zomwe zingakhazikitsire nambala iyi:

• Cholakwika cholowera liwiro sensa B
• Mawaya owonongeka, otayirira kapena owotcha ndi / kapena zolumikizira
• Cholakwika cha PCM kapena pulogalamu ya PCM yolakwika
• Kudzikundikira kwa zinyalala zazitsulo pa maginito

Njira zowunikira ndikukonzanso

Malo oyambira nthawi zonse amayang'ana ma bulletins aukadaulo (TSB) pagalimoto yanu. Vuto lanu limatha kukhala vuto lodziwika bwino lokonzedwa ndi wopanga ndipo limatha kukupulumutsirani nthawi ndi ndalama mukamayesa kusaka.

Digito volt / ohmmeter (DVOM), buku lothandizira opanga makina, chojambulira chowunikira, komanso oscilloscope chithandizira kuzindikira molondola nambala ya P2768.

Nthawi zambiri ndimayambitsa matenda anga ndikuwunika mawonekedwe a zingwe zamagetsi ndi zolumikizira. Ndikanakonza masekete aliwonse ofupika bwino kapena otseguka komanso / kapena zolumikizira ndisanapite. Onetsetsani kuti mwayang'ana batire, zingwe zama batri ndi chingwe chikutha panthawiyi, ndikuwonanso zomwe jenereta yatulutsa.

Kenako ndinalumikiza sikaniyo ku doko lodziwira, ndikutenga ma code onse osungidwa, ndikulemba kuti ndigwiritse ntchito mtsogolo. Ndimayang'aniranso pazithunzi zoyimitsa panthawiyi.

Gwiritsani ntchito seweroli posanthula kuti mudziwe dera lomwe lili lolakwika ngati kulumikizana ndi ma sensa akupezeka. Kuti mumve zambiri zolondola ndi sikani, chepetsani kusuntha kwanu kuti mukhale ndi zofunikira zokha.

Zinyalala zazitsulo zamagetsi zamagetsi zamagetsi zolowera ndi / kapena zotumphukira zimatha kuyambitsa masensa apakatikati. Chotsani sensa ndikufufuza zinyalala zachitsulo. Chotsani zinyalala zowonjezera pamaginito musanabwezeretse. Ndimayang'ananso malo opumira ndi / kapena notches pa gudumu la riyakitala kuti iwonongeke kapena kuvala.

Ndimagwiritsa ntchito DVOM kuyesa kulimbana ndi mphamvu zamagetsi zamagetsi zamagetsi zamagetsi zamagetsi ndi mphamvu zamagawo motsatira zomwe wopanga (onani Service Manual kapena data yonse). Ndingasinthe masensa omwe sakukwaniritsa zofunikira za wopanga.

Kulephera kwa owongolera kumatha kuchitika ngati owongolera onse osatsekedwa asanayesedwe kukana kapena kupitiriza ndi DVOM.

Ganizirani zolakwika za PCM kapena PCM ngati pulogalamu ya P2768 yasungidwa ndipo ma circuits onse ndi masensa ali muntchito yoyenera ndikukwaniritsa zofunikira zaopanga.

Zowonjezera zowonjezera:

• Zinyalala zowonjezera zazitsulo (zomwe zimakopeka ndi mphamvu yamagetsi yamagetsi) zimatha kuyambitsa zolakwika za I / O zowunikira mwachangu.
• Kusiyana pakati pa sensa ndi riyakitala ndikofunikira. Onetsetsani kuti mawonekedwe omwe akukwera / mabowo omangika ndiwowonekeratu pazinyalala ndi zotchinga.
• Ngati kuli kofunikira kuti muchotse masensa olowera ndi / kapena otulutsira kufalikira, samalani. Madzi otentha otentha amatha kutuluka mdzenje.
• Fufuzani madzi otengera m'dera la cholumikizira cholumikizira liwiro, chifukwa masensa ena amatha kutayikira mkati.

Zokambirana zokhudzana ndi DTC

• Pakadali pano palibe mitu yofananira m'mabwalo athu. Tumizani mutu watsopano pamsonkhano tsopano.

Mukufuna thandizo lina ndi nambala yanu ya p2768?

Ngati mukufunabe thandizo ndi DTC P2768, 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.
