P0191 Fuel Rail Pressure Sensor "A" Circuit Range/Performance

Khodi Yovuta ya OBD-II - P0191 - Kufotokozera Zaukadaulo

P0191 Fuel Rail Pressure Sensor "A" Circuit Range/Performance.

P0191 ndi Diagnostic Trouble Code (DTC) ya "Fuel Rail Pressure Sensor Circuit Range/Performance". Izi zitha kuchitika pazifukwa zingapo ndipo zili kwa makinawo kuti azindikire chomwe chimayambitsa vutoli.

Kodi vuto la P0191 limatanthauza chiyani?

Izi Generic Transmission / Engine DTC nthawi zambiri imagwira ntchito pama injini ambiri opangira mafuta, mafuta ndi dizilo, kuyambira 2000. Code imagwira ntchito kwa onse opanga monga Volvo, Ford, GMC, VW, ndi zina zambiri.

Nambala iyi imangotanthauza kuti chizindikirocho cholowera munthawi yamagetsi sichikugwirizana ndi chomwe chimaperekedwa ku injiniyo. Izi zitha kukhala kulephera kwamakina kapena kulephera kwamagetsi, kutengera wopanga magalimoto, mtundu wamafuta ndi makina amafuta.

Njira zothetsera mavuto zimatha kusiyanasiyana kutengera wopanga, mtundu wa njanji yamagetsi, mtundu wa njanji yamagetsi, ndi mitundu yamawaya.

ndemanga. Khodi iyi ikhoza kukhudzana ndi:

• OBD-II Trouble Code P0171 (Mafuta amafuta olemera kwambiri)
• OBD-II Trouble Code P0172 (Njira Yotsamira Kwambiri Yamafuta)

Zizindikiro

Zizindikiro za chikhombo cha injini ya P0191 zitha kuphatikizira izi:

• Nyali Yazizindikiro Zosagwira (MIL) yaunikira
• Kupanda mphamvu
• Injini imayamba koma siyikuyenda
• Kuchepetsa mafuta
• Injini ikhoza kuyimitsa kapena kukayikira
• Injini ikhoza kuzimitsa galimoto ikayimitsidwa
• Kununkhira kwachilendo kwa chitoliro chotulutsa mpweya
• Palibe zizindikiro zowonekera
• DTCs P0171 ndi/kapena P0172 zimasungidwa mu gawo lowongolera mphamvu.

Zifukwa za P0191 kodi

Zifukwa zomwe zingakhazikitsire nambala iyi:

• Kuthamanga mafuta
• Kutsika kwa mafuta
• Kuwonongeka kwa FRP sensor
• Kukaniza kwambiri dera
• Kutuluka kosalala
• Mlingo wotsika kapena wopanda mafuta
• Opunduka kachipangizo kuthamanga mafuta
• Kusokonekera kwa Sensor Pressure Sensor yamafuta
• Cholumikizira cha sensor yamafuta olakwika
• Zowonongeka zamagetsi zamagetsi

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.

Komanso, ndi nambala iyi, onetsetsani kuti mulibe ma foni okhudzana ndi pampu wamafuta. Ngati muli ndi ma code ena omwe akuwonetsa vuto ndi pampu yamafuta, pezani nambala iyi poyamba ndikunyalanyaza nambala ya P0191. Makamaka zikafika pagulu lazoyambitsa.

Kenako pezani chojambulira cha njanji yamagalimoto m'galimoto yanu. Zitha kuwoneka ngati izi:

Mukazindikira, yang'anani zowonera zolumikizira ndi zingwe. Sakani scuffs, scuffs, mawaya owonekera, zopsereza, kapena pulasitiki wosungunuka. Chotsani zolumikizira ndikuyang'anitsitsa malo (zitsulo) mkati mwa zolumikizira. Onani ngati akuwoneka olunda, owotcha, kapena obiriwira poyerekeza ndi mtundu wachitsulo womwe mumakonda kuwawona. Ngati pakufunika kuyeretsa kosachiritsika, mutha kugula zotsukira zamagetsi pamalo aliwonse ogulitsa. Ngati izi sizingatheke, pezani 91% akusisita mowa ndi burashi ya pulasitiki yoyera kuti muyeretsedwe. Kenako awumitseni kuti awume, atenge dielectric silicone pawiri (zomwezi zomwe amagwiritsa ntchito popangira mababu ndi ma waya amagetsi) ndikuyika malo omwe amalumikizirana.

Kenako onetsetsani kuti payipi yotsekemera yolumikizira sensa ndi zochulukirapo sizikudontha (ngati zigwiritsidwa ntchito). Yendani maulalo onse azitsulo panjira yothamangitsira njanji ndikudyetsa kangapo. Sinthani ngati kuli kofunikira.

Ngati muli ndi chida chosakira, chotsani ma code azovuta zakumbukiro ndikuwona ngati nambala yanu ibwerera. Ngati sizili choncho, ndiye kuti mwina pali vuto lolumikizana.

Khodi ikabwerera, tifunikira kuyesa sensa ndi makina osinthira. Chotsani kiyi poyamba, kenako lolani makina othamangitsira mafuta. Kenako gwirizanitsani chida chowonera ndikuwona momwe mafuta akugwiritsira ntchito. Tsegulani fungulo ndikuwona kukakamira kwa gauge poyerekeza ndi kuwerenga kwa chida chosakira. Chida chojambulira ndi transducer ziyenera kukhala mkati mwa 5 psi. Kutalika mainchesi.

Ngati mayesero onse adutsa mpaka pano ndipo mukupitiriza kupeza P0191 code, chinthu chomaliza kuyang'ana ndi kugwirizana kwa PCM. Lumikizani zolumikizira ndikuwunika mosamala ma terminals (zigawo zachitsulo) mkati mwa zolumikizira. Onani ngati zikuwoneka zadzimbiri, zopserera, kapena zobiriwira poyerekeza ndi mtundu wachitsulo wanthawi zonse womwe mwina mwazolowera kuwona.

Ngati mayeso onse atadutsa, koma mupezabe nambala ya P0191, zikuwoneka kuti yalephera PCM. Musanalowe m'malo mwa PCM ndikofunikira, tikulimbikitsidwa kuti musinthe mwamphamvu (siyani batri). Kungakhale kofunikira kusinthitsa mphamvu yamagetsi yamagetsi.

Chenjezo! Pa injini za dizilo zokhala ndi mafuta a njanji wamba: ngati chiwongolero cha njanji yamafuta chikuganiziridwa, mutha kukhala ndi katswiri kuti akuyikireni sensa. Sensa iyi ikhoza kuyikidwa padera kapena kukhala gawo la njanji yamafuta. Mulimonse momwe zingakhalire, mphamvu ya njanji yamafuta a injini za dizilo ikatentha kwambiri imakhala yosachepera 2000 psi, ndipo ponyamula katundu imatha kupitilira 35,000 psi. Ngati sichimasindikizidwa bwino, kuthamanga kwamafuta kumeneku kumatha kudula khungu, ndipo mafuta a dizilo amakhala ndi mabakiteriya omwe angayambitse poizoni m'magazi.

Kodi makaniko amazindikira bwanji code ya P0191?

• Makaniko adzagwiritsa ntchito scanner ya OBD-II kuti apeze deta yoziziritsa kuti adziwe momwe galimotoyo inalili pamene DTC P0191 idakhazikitsidwa ndi gawo lowongolera mphamvu (PCM).
• Imamaliza kuyesa ndikugwiritsa ntchito data yeniyeni kuti idziwe ngati kuwerengera kwamafuta kuli koyenera.
• Amagwiritsa ntchito choyezera kuthamanga kwamafuta kuti adziwe ngati pali vuto la sensa kapena vuto la kuthamanga kwamafuta.
• Ngati kuthamanga kwa mafuta kuli bwino, adzagwiritsa ntchito oscilloscope kuti ayang'ane cholumikizira cholumikizira njanji yamafuta ndi waya. Cholinga cha izi ndikutsimikizira kuti ma sensor circuitry ndi osasunthika.
• Sensa imakhala yolakwika kwambiri ngati kuthamanga kwenikweni kwamafuta kuli bwino ndipo ma sensor circuitry ndi abwino.

Zolakwa Zomwe Zimachitika Mukamazindikira Khodi P0191

Kulakwitsa kofala mukazindikira DTC P0191 ndikunyalanyaza zinthu zina zomwe zingafunike kukonzedwa ndikulowetsa kachipangizo kambiri ya njanji yamafuta.

Mawaya osokonekera kapena osokonekera, chowongolera mphamvu yamafuta olakwika, kapena pampu yamafuta yolakwika ndi zinthu zomwe nthawi zambiri zimamanyalanyazidwa pofufuza ndi kumaliza kukonza.

Kodi P0191 ndi yowopsa bwanji?

DTC P0191 imadziwika kuti ndiyowopsa chifukwa imadziwika kuti imayambitsa zovuta zoyendetsa. Kuyendetsa ndi kachidindo kameneka kungapangitse galimoto kuyimilira kapena kugwedezeka pamene mukuyendetsa. Pakhoza kukhalanso kuwonjezeka kwa mafuta ogwiritsidwa ntchito, omwe angakhale okwera mtengo. Ndikofunika kuti mutenge kachidindo kameneka ndikuzindikira ndikukonza mwamsanga.

Ndi kukonza kotani komwe kungakonze P0191?

• Kuchotsa pampu yamafuta
• Kuchotsa owongolera wamagetsi
• Konzani mawaya aliwonse othyoka, ophwanyika, kapena achidule omwe amatsogolera ku sensor yamafuta.
• Kukonza cholumikizira cha dzimbiri ku sensa yamafuta
• Kusintha kwa sensor yamafuta amafuta
• Kukonza zotayikira zilizonse mu injini

Ndemanga zowonjezera zomwe muyenera kuziganizira ponena za code P0191

Nthawi zambiri, pali zigawo zina zomwe zimayambitsa DTC iyi. Tengani nthawi yanu ndikuganizira zotheka zonse musanaganize kuti sensor yamafuta njanji ili ndi vuto. Komanso, onetsetsani kuti muli ndi zida zoyenera kuti muzindikire. Mufunika sikani ya OBD-II ndi oscilloscope.

Mukufuna thandizo lina ndi nambala yanu ya p0191?

Ngati mukufunabe thandizo ndi DTC P0191, lembani funso mu ndemanga pansipa pamutuwu.

Zindikirani. Izi zimaperekedwa pazambiri zokha. Sitiyenera kugwiritsidwa ntchito ngati upangiri wokonza ndipo sitili ndi udindo pazomwe mungachite pagalimoto iliyonse. Zonse zomwe zili patsamba lino zimatetezedwa ndi kukopera.
