P050F Kutsegula kotsika kocheperako pakuwombera mwadzidzidzi

Mapepala a OBD-II DTC

Kutulutsa kotsika kotsika kwambiri mu braking yadzidzidzi

Kodi izi zikutanthauzanji?

Code Generic Powertrain Diagnostic Trouble Code (DTC) imagwiritsidwa ntchito kwambiri pagalimoto zambiri za OBD-II. Izi zingaphatikizepo, koma sizingokhala ku, Chevrolet, Ford, VW, Buick, Cadillac, ndi zina zambiri.

Khodi yosungidwa P050F imatanthawuza kuti gawo loyendetsa mphamvu ya powertrain (PCM) lalandila zolowetsa kuchokera ku vacuum brake sensor (VBS) yomwe ikuwonetsa kuti sikokwanira kutulutsa kwa brake.

Ngakhale pali mitundu ingapo (kuphatikiza ma hydraulic ndi zamagetsi) yama brake othandizira, nambala iyi imangogwira ntchito kwa iwo omwe amagwiritsa ntchito zingalowe mu injini ndi cholimbikitsira cha servo.

Chowonjezera chotsitsira mavutowa chimakhala pakati pa choyimitsa ndi cholembera chachikulu. Amamangiriridwa kumtunda wa bulkhead (nthawi zambiri kutsogolo kwa mpando wa driver). Ikhoza kupezeka ndi hood yotseguka. Mbali ina yolumikizira yolumikizira imadutsa mumutu waukulu ndikumata dzanja lophwanyika. Mbali ina ya ndodo yogwiritsira ntchito ikukankhira pisitoni yamphamvu yamphamvu, yomwe imakankhira madzi amadzimadzi kupyola mizere yopumira ndikuyambitsa mabuleki a gudumu lirilonse.

Chombocho chimakhala ndi thupi lachitsulo lokhala ndi zotsekemera zazikulu mkati. Chilimbikitso choterechi chimatchedwa cholimbikitsira chobwezera chopumira kawiri. Pali magalimoto ena omwe amagwiritsa ntchito diaphragm amplifier imodzi, koma izi ndizochepa. Injini ikamayendetsa, chimanjamanja chimagwiritsidwa ntchito pachikopacho, chomwe chimakoka pang'ono lever. Valavu yokhotakhota (mu payipi ya zingalowe) imalepheretsa kutayika kwamphamvu injini ikamadzaza katundu.

Ngakhale magalimoto ambiri a dizilo amagwiritsa ntchito ma hydraulic booster system, ena amagwiritsa ntchito cholumikizira chopumira. Popeza injini za dizilo sizipanga chimbudzi, pampu yoyendetsedwa ndi lamba imagwiritsidwa ntchito ngati gwero loyambira. Makina ena onse opumirawo amagwiranso ntchito chimodzimodzi ndi makina amagetsi. 

Kapangidwe kamene kamakhala ndi VBS kamakhala ndi kachipangizo kamene kamakhala mkati mwa kabowo kakang'ono kotsekedwa mu pulasitiki. Kutulutsa kwamkati (kuchuluka kwa mpweya) kumayeza mu kilopascals (kPa) kapena mainchesi a mercury (Hg). VBS imalowetsedwa kudzera mu grommet yayikulu ya mphira m'nyumba yanyumba ya servo. Vuto lakutulutsidwa likukula, kutsutsana kwa VBS kumachepa. Izi zimapangitsa mphamvu ya dera la VBS. Kupanikizika kwa zingalowe kumachepa, zotsatira zake zimachitika. PCM imalandira kusintha kwamagetsi uku ngati kuthamanga kwa servo kumasintha ndikuchita mogwirizana.

PCM ikazindikira mulingo wopumira wa brake kunja kwa parameter, P050F khodi idzasungidwa ndipo nyali yowunikira (MIL) itha kuwunikira.

Chithunzi cha makina opanikizira (vacuum) a brake booster / VBS:

Kodi kuuma kwa DTC kumeneku ndi kotani?

Kutulutsa kotsika kotsika mu cholumikizira cha brake kumatha kukulitsa kuchuluka kwa mphamvu zofunikira kuti mutsegule. Izi zitha kuchititsa kuti mugundane ndi galimotoyo. Vuto P050F liyenera kukonzedwa mwachangu.

Kodi zina mwazizindikiro za code ndi ziti?

Zizindikiro za nambala ya injini ya P050F itha kuphatikizira:

• Kuyimba kwake kumamveka pamene chinsalu chanyema chimapanikizika
• Kulimbikira kuyesayesa kofunikira kuti musindikize chowombera
• Ma code ena akhoza kusungidwa, kuphatikiza manifolds a Manifold Absolute Pressure (MAP).
• Mavuto pakugwiritsa ntchito injini komwe kumachitika chifukwa chotsuka kwa vacuum

Kodi zina mwazomwe zimayambitsa codezi ndi ziti?

Zifukwa za code iyi zitha kuphatikizira izi:

• Kutayikira mkati ndikulimbikitsanso kwama brake
• Choyipa choyipa chotsukira
• Chotseka chodulira kapena cholumikizira
• Valavu ya cheke yosabwezera mu payipi yotulutsa zingalowe.
• Kutulutsa kokwanira mu injini

Ndi njira ziti zomwe zingasokoneze P050F?

Choyamba, ngati phokoso laphokoso limamveka mukamakanikiza chidule ndikudina chidacho kumafunikira kulimbikira, cholumikizira chake chimakhala cholakwika ndipo chiyenera kusinthidwa. Tikulimbikitsidwa kuti mugwiritse ntchito cholimbikitsira cholemera (chogulitsidwa ndi chida chamagetsi) chifukwa kutayika kwamphamvu ndi chinthu chachikulu pakulephera kwachilimbikitso.

Mufunika makina osakira matenda, chopukusira chokhala ndi dzanja, digito volt / ohmmeter, ndi gwero lodalirika lazidziwitso zamagalimoto kuti mupeze nambala ya P050F.

Kuzindikira kwa nambala ya P050F kuyambira (kwa ine) ndikuwunika mawonekedwe a payipi yotulutsa vutoli. Ngati payipi ilumikizidwa ndikugwira bwino ntchito, yambitsani injini (KOER) ndikuteteza galimotoyo poyimika magalimoto kapena posalowerera ndale. Chotsani mosamala valavu yoyendera njira imodzi (kumapeto kwa payipi yopumira) kuchokera ku chilimbikitso ndikuwonetsetsa kuti pali cholowa chokwanira ku chilimbikitsocho. Ngati mukukayika, mutha kugwiritsa ntchito cholembera chamagetsi kuti muwone ngati zingalowe.

Zofunikira pakutsuka kwama injini zitha kupezeka pagwero lazidziwitso zamagalimoto. Ngati injini sikutulutsa zingalowe zokwanira, ziyenera kukonzedwa musanapitilize ndi vutoli. Ngati chilimbikitso chili ndi zingalowe zokwanira ndipo zikuwoneka kuti zikugwira bwino ntchito, funsani gwero lazidziwitso zamagalimoto anu pazomwe mungayesere poyeserera ndi malongosoledwe ake. Muyeneranso kupeza zithunzi zolumikizira, zolumikizira mawonekedwe, ndi ma pinout olumikizira. Izi zidzafunika kuti matenda athe.

Chotsegulira ndi kuyimitsa (KOEO), chotsani cholumikizira ku VBS ndikugwiritsa ntchito mayeso oyeserera kuchokera ku DVOM kuti muwone voliyumu yolowera pa pini yoyenera pa cholumikizira. Fufuzani kuti muone ngati muli ndi mayeso olakwika. Ngati magetsi ndi nthaka zilipo, pitani pa 2.

mwatsatane 2

Gwiritsani ntchito DVOM (pamalo a Ohm) kuti muwone VBS. Tsatirani njira zoyeserera zomwe wopanga amapanga ndi mawonekedwe ake poyesa VBS. Ngati sensa ilibe tanthauzo, ndiyopanda ntchito. Ngati sensa ili bwino, pitani ku 3.

mwatsatane 3

Ndi KOER, gwiritsani ntchito malo abwino a DVOM nipple kuyeza mphamvu yamagetsi pa cholumikizira cha VBS. Pansi poyesedwa koyipa kumabweretsa batire yabwino. Mphamvu yamagetsi iyenera kuwonetsedwa pamlingo wofanana ndi sensa ya MAP pazowonetsa deta. Chithunzi cha kukakamizidwa motsutsana ndi zingalowe motsutsana ndi magetsi chimapezekanso pazomwe mungapeze pagalimoto yanu. Yerekezerani ndi magetsi omwe amapezeka mdera lazizindikiro ndi zolowera pachithunzicho. Ndikuganiza kuti VBS ndiyolakwika ngati sikugwirizana ndi chithunzicho. Ngati magetsi ali mkati mwazinthu, pitani ku gawo 4.

mwatsatane 4

Pezani PCM ndikugwiritsa ntchito DVOM kuti muwone ngati VBS yamagetsi yamagetsi ilipo pamenepo. Yesani dera lazizindikiro za VBS pogwiritsa ntchito mayeso oyeserera ochokera ku DVOM. Lumikizani mayeso oyipa kutsogolera ku nthaka yabwino. Ngati chizindikiro cha VBS chomwe mwapeza pa cholumikizira cha VBS sichipezeka pamayendedwe ofanana ndi cholumikizira cha PCM, mukuganiza kuti muli ndi gawo lotseguka pakati pa PCM ndi VBS. Ngati ma circuits onse ali bwino ndipo VBS ikwaniritsa zofunikira; Mutha kukhala ndi vuto la PCM kapena pulogalamu ya PCM.

• Unikani za Technical Service Bulletins (TSB) za zolembedwa zomwe zili ndi zizindikilo zomwezo. TSB yolondola imatha kukuthandizani pakuzindikira.
• Tsutsani RMB pokhapokha zina zonse zitatha

Zokambirana zokhudzana ndi DTC

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

Mukufuna thandizo lina ndi nambala yanu ya P050F?

Ngati mukufunabe thandizo ndi nambala ya P050F, 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.
