P007F Lamulira Mpweya Wozizira Kutentha SENSOR Correlation Bank

Mapepala a OBD-II DTC

Limbikitsani Kutentha Kwa Mpweya Wowonongeka, Bank1 / Bank2

Kodi izi zikutanthauzanji?

Code Generic Powertrain Diagnostic Trouble Code (DTC) imagwiritsidwa ntchito kwambiri pagalimoto zambiri za OBD-II. Izi zitha kuphatikizira, koma sizingokhala mu, Ford, Range Rover, Mercedes-Benz, ndi zina zambiri.

Khodi yosungidwa P007F imatanthawuza kuti gawo loyendetsa mphamvu ya powertrain (PCM) lapeza kusagwirizana pakati pama siginecha ophatikizika pakati pama sensa a kutentha kwa mpweya (CAT) kwamagulu amainjini. Bank 1 amatanthauza gulu la injini lomwe lili ndi silinda nambala wani.

Monga mukumvetsetsa kuchokera pamafotokozedwe amtunduwu, P007F imangogwira ntchito pamagalimoto omwe ali ndi machitidwe okakamiza olowetsa mpweya komanso magwero angapo olowetsa mpweya. Kulowetsa mpweya kumaphatikizanso matupi opindika, ndipo makina okakamiza amakonzedwa mozungulira ma turbocharger ndi ma supercharger.

Masensa a CAT nthawi zambiri amakhala ndi thermistor m'nyumba yapulasitiki. Chojambulira cha CAT chimalowetsedwa kudzera pa chubu chotsitsa mpweya (kuchokera panja mpaka mkati) ndi cholumikizira choyimitsidwa pama waya awiri. Imaikidwa kuti mpweya wozungulira womwe umalowa m'malo opangira ma turbocharger (mutatuluka mpweya / intercooler) udutsemo. Chojambulira cha CAT nthawi zambiri chimapangidwa kuti chizimangiriridwa kapena kulowetsedwa muzakudya za turbocharger / supercharger pafupi ndi intercooler.

Mulingo wokana kukana kwa sensa ya CAT umatsika chifukwa kutentha kwenikweni kwamlengalenga kumawonjezeka. Izi zimapangitsa kuti voliyumu yoyendera ifike pamlingo woyenera. PCM imazindikira kusintha kumeneku pamagetsi amagetsi a CAT monga kusintha kwa kutentha kwa mpweya ndikuchitapo kanthu molingana.

Masensa a CAT amapereka chidziwitso ku PCM kuti apititse patsogolo mphamvu zamagetsi zamagetsi ndikulimbitsa magwiridwe antchito a valavu, komanso zina mwazinthu zoperekera mafuta komanso nthawi yoyatsira.

PCM ikazindikira ma voltage amagetsi kuchokera ku CAT sensors (pamizere yoyamba ndi yachiwiri yamainjini) yomwe ikuwonetsa kusiyana komwe kumadutsa magawo ovomerezeka, nambala ya P007F idzasungidwa ndipo nyali yowunikira (MIL) itha kuwunikira. Zitha kutenga mayendedwe angapo poyenda polephera kuunikira MIL.

Kodi kuuma kwa DTC kumeneku ndi kotani?

Kugwiritsa ntchito injini ndi mafuta mosakayikira zidzasokonekera chifukwa cha zomwe zingasunge P007F code. Iyenera kukhala yolemetsa.

Kodi zina mwazizindikiro za code ndi ziti?

Zizindikiro za nambala ya injini ya P007F itha kuphatikizira:

• Kuchepetsa ntchito ya injini
• Kutambasula kuposa kuyamwa kwanthawi zonse kapena kutsitsa mukamafulumira
• Kuchotsa mwachangu
• Wolemera kapena wowonda utsi
• Kuchepetsa mafuta

Kodi zina mwazomwe zimayambitsa codezi ndi ziti?

Zifukwa zamakina ophatikizira awa ndi monga:

• Chojambulira cha CAT cholakwika
• Payipi yolowera kapena yophulika yolowetsa mpweya
• Tsegulani kapena zazifupi mu waya wa CAT kapena cholumikizira
• Zowonongeka za Air Air
• Kukhazikitsa makina opangira mankhwala a methanol
• Pulogalamu ya PCM kapena PCM yolakwika

Ndi njira ziti zomwe zingasokoneze P007F?

Ndikazindikira ma code omwe amagwirizana ndi sensa ya CAT, ndimayamba ndikuwona kuti palibe choletsa kupuma kwa mpweya kudzera pa intercooler.

Ngati palibe zotchinga mu intercooler ndipo fyuluta ya mpweya ndiyabwino; kuyang'anitsitsa mawonekedwe onse a CAT sensor wiring ndi zolumikizira zili bwino.

Ngati galimotoyo ili ndi makina opangira mankhwala a methanol, PCM imafunikira kukonzedwa kuti ikwaniritse magwiridwe antchito. PCM nthawi zambiri imapitilizabe kusunga malamulowo mpaka pomwe kukonzanso kumachitika.

Ndidzafunika chowunikira, digito volt / ohmmeter (DVOM) ndi gwero lodalirika lamagalimoto poyesera kupeza nambala ya P007F.

Ndikadapitilizabe kulumikiza sikaniyo padoko lodziwitsa anthu zagalimotoyi ndikupeza ma nambala onse osungidwa ndikuimitsa chimango. Sungani deta yazithunzi imapereka chithunzithunzi cha zomwe zidachitika panthawi yolakwitsa yomwe idatsogolera ku P007F code yosungidwa. Ndikulemba izi chifukwa zitha kukhala zothandiza ndikamafufuza mozama momwe ndikufunira. Tsopano ndimatsitsa ma code ndikuyesa kuyendetsa galimoto kuti ndiwone ngati nambala yachotsedwayo.

Ngati P007F yasinthidwa nthawi yomweyo:

1. Gwiritsani ntchito mayeso oyeserera kuchokera ku DVOM kuti muziyesa mayendedwe olumikizira sensa ndi mayeso oyipa kuti muyese kulumikizana ndi nthaka.
2. Tsegulani fungulo ndi injini (KOEO) ndikuyang'ana ma voltage (makamaka 5V) ndi pansi pazolumikizira za CAT.

Pakapezeka voliyumu yoyenera ndi nthaka:

1. Lumikizaninso transducer ndikuyesa mayendedwe a CAT transducer ndi mayeso oyeserera a DVOM (kafukufuku wapansi atakhazikika pamalo abwino odziwika bwino).
2. Tsegulani kiyi ndi injini yomwe ikuyendetsa (KOER) ndikuyang'ana dera loyendetsa kachipangizo pomwe injini ikuyenda. Kungakhale kofunikira kuonjezera liwiro la injini kapena kuyendetsa galimotoyo kuti muyese bwino mayendedwe amtundu wa CAT sensor.
3. Chiwembu cha kutentha motsutsana ndi magetsi atha kupezeka pagwero lazidziwitso zamagalimoto. Gwiritsani ntchito kuti muwone ngati sensa ikugwira ntchito bwino
4. Ngati masensa aliwonse a CAT sakuwonetsa mulingo woyenera wamagetsi (wogwirizana ndi CAT weniweni), akuwakayikira kuti ndi olakwika. Mutha kugwiritsa ntchito laser pointer infrared thermometer kuti muyike CAT weniweni.

Ngati dera lama sensor likuwonetsa mulingo woyenera wamagetsi:

• Gwiritsani ntchito DVOM kuyesa gawo lazizindikiro (za sensa yomwe ikufunsidwa) pa cholumikizira cha PCM. Ngati chizindikirocho chikupita ku chojambulira koma osati PCM chojambulira, konzani dera lotseguka pakati pa zinthu ziwirizi.

Mutha kungoyesa mayendedwe amtundu uliwonse pogwiritsa ntchito DVOM mutachotsa PCM (ndi owongolera onse). Tsatirani cholumikizira cholumikizira ndi zingwe zolumikizira kuti muwone kulimbana ndi / kapena kupitilira kwa dera lanu.

Ngati ma circuits onse akugwira ntchito monga mukuyembekezera, mutha kugwiritsa ntchito DVOM (ndi gwero lanu lazidziwitso zodalirika zamagalimoto) kuyesa masensa ena a CAT. Onaninso gwero lazidziwitso zamagalimoto anu pazomwe mungayese poyesa zigawo zikuluzikulu ndikuyika DVOM kumalo osagwirizana. Onetsetsani masensa mukamasula. Masensa a CAT omwe sagwirizana ndi zofunikira za opanga ayenera kuonedwa ngati olakwika.

Ingokayikirani kulephera kwa PCM kapena pulogalamu ya PCM ngati masensa onse a CAT ndi ma circuits ali munjira.

• Mwa kufananitsa galimotoyo, zizindikilo, ndi manambala omwe amasungidwa m'makalata aukadaulo (TSBs), mutha kupeza thandizo pakuwunika.

Zokambirana zokhudzana ndi DTC

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

Mukufuna thandizo lina ndi nambala yanu ya P007F?

Ngati mukufunabe thandizo ndi nambala ya P007F, lembani funso m'mawu pansipa.

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.
