I-P0191 Fuel Rail Pressure Sensor “A” Circuit Range/Performance

Ikhodi Yenkinga ye-OBD-II - P0191 - Ishidi Ledatha

I-P0191 Fuel Rail Pressure Sensor "A" Ibanga Lesifunda/Ukusebenza.

I-P0191 iyikhodi Yenkinga Yokuxilonga (i-DTC) "ye-Fuel Rail Pressure Sensor Circuit Range/Performance". Lokhu kungenzeka ngezizathu ezimbalwa futhi kukumakhenikha ukuthi ahlonze imbangela ethile yale khodi eqalwa esimweni sakho.

Isho ukuthini ikhodi yenkinga P0191?

Le Generic Transmission / Engine DTC imvamisa isebenza ezinjinini eziningi zokujova uphethiloli, zombili uphethiloli nodizili, kusukela ngo-2000. Ikhodi isebenza kubo bonke abakhiqizi abanjengoVolvo, Ford, GMC, VW, njll.

Le khodi ibhekise eqinisweni lokuthi isignali yokufaka evela kunzwa yengcindezi yesitimela sikaphethiloli ayihambelani naleyo enikezwe injini. Lokhu kungaba ukwehluleka kwemishini noma ukwehluleka kukagesi, kuya ngomkhiqizi wezimoto, uhlobo lukaphethiloli nohlelo lwamafutha.

Izinyathelo zokuxazulula inkinga zingahluka ngokuya ngomenzi, uhlobo lwesistimu yengcindezi yesitimela, uhlobo lwenzwa yengcindezi yesitimela, nemibala yocingo.

Ukubhala. Le khodi ingase ihlobane ne:

• Ikhodi Yenkinga ye-OBD-II P0171 (Isistimu yesibaseli inothe kakhulu)
• Ikhodi Yenkinga ye-OBD-II P0172 (Isistimu Yezibaseli Encike Ngokweqile)

Izimpawu

Izimpawu zekhodi yenjini engu-P0191 zingafaka:

• Ilambu Lenkomba Yokungasebenzi (MIL) likhanyisiwe
• Ukuntuleka kwamandla
• Injini iyaqala kodwa ayisebenzi
• Ukwehla komnotho kaphethiloli
• Injini ingase imane noma inbaze
• Injini ingase ivale lapho imoto imiswa
• Iphunga elingavamile elivela epayipini lokukhipha umoya
• Azikho izimpawu eziphawulekayo
• Ama-DTC P0171 kanye/noma i-P0172 agcinwe kumojula yokulawula amandla.

Izimbangela zephutha P0191

Izizathu ezingaba khona zokusetha le khodi:

• Ingcindezi ephezulu kaphethiloli
• Ingcindezi kaphethiloli ephansi
• Inzwa ye-FRP eyonakele
• Ukumelana okweqile esifundeni
• Ukuvuza komshini
• Izinga eliphansi noma elingenawo uphethiloli
• Inzwa yengcindezi engaphelele
• Ukungasebenzi Kwesensa Yezinzwa Zengcindezi Yamafutha
• Isixhumi senzwa yomfutho kaphethiloli engalungile
• Isilawuli sengcindezi esinephutha

Izinqubo zokuxilonga nokulungisa

Iphuzu elihle lokuqala ngaso sonke isikhathi ukuhlola ama-bulletins ezinsizakalo zobuchwepheshe (i-TSB) yemoto yakho ethile. Inkinga yakho ingaba inkinga eyaziwa ngesilungisi esikhishwe ngumkhiqizi futhi ingakongela isikhathi nemali ngenkathi uxazulula inkinga.

Futhi, ngale khodi ethile, qiniseka ukuthi awunawo amakhodi ahlobene nompompi kaphethiloli / ingcindezi kaphethiloli. Uma unamanye amakhodi akhombisa inkinga ngepompo kaphethiloli, thola le khodi kuqala bese uyishaye indiva ikhodi ye-P0191. Ikakhulu uma kukhulunywa ngenkinga yokwethulwa.

Bese uthola inzwa yengcindezi yesitimela sikaphethiloli emotweni yakho ethile. Kungabukeka okufana nalokhu:

Uma usutholakele, hlola ngokubonakalayo izixhumi nezintambo. Bheka ama-scuffs, ama-scuffs, izintambo eziveziwe, amamaki okushisa, noma ipulasitiki ebunjiwe. Nqamula izixhumi futhi uhlole ngokucophelela amatheminali (izingxenye zensimbi) ngaphakathi kwezixhumi. Bona ukuthi zibukeka zigqwalile, zishisiwe, noma kungenzeka ziluhlaza ngokuqhathaniswa nombala wensimbi ojwayelekile okungenzeka ujwayele ukuwubona. Uma kudingeka ukuhlanzwa ekugcineni, ungathenga okokuhlanza oxhumana kagesi kunoma yisiphi isitolo sezingxenye. Uma lokhu kungenzeki, thola u-91% wokuhlikihla utshwala kanye nebhulashi elilula lepulasitiki ukuze uwahlanze. Bese bewomisa umoya, bathathe i-dielectric silicone compound (into efanayo abayisebenzisela abaphathi be-bulb kanye nezintambo ze-plug plug) bese bebeka lapho amatheminali axhumana khona.

Bese ubheka ukuthi i-hose vacuum exhuma inzwa kokuphindaphindwayo kokungenisi ayivuzi (uma isetshenzisiwe). Hlola konke ukuxhumeka kwepayipi le-vacuum enjinini yengcindezi yesitimela kanye nokuphindaphindeka kokudla. Shintsha uma kunesidingo.

Uma unethuluzi lokuskena, sula amakhodi ezinkinga zokuxilonga kwimemori bese ubona ukuthi ikhodi iyabuya yini. Uma lokhu kungenjalo, kungenzeka ukuthi kunenkinga yokuxhuma.

Uma ikhodi ibuya, kuzodingeka sivivinye inzwa ngegeji yokucindezela ngomshini. Cisha ukhiye kuqala, bese uxhuma inzwa yengcindezi kaphethiloli. Bese uxhuma ithuluzi lokuskena bese ubona ingcindezi kaphethiloli kuthuluzi lokuskena. Vula ukhiye bese ubona ingcindezi esilinganisweni uma kuqhathaniswa nokufundwa kwethuluzi lokuskena. Ithuluzi lokuskena ne-transducer kufanele libe ngaphakathi kwe-5 psi. Ngokwe-intshi.

Uma zonke izivivinyo sezidlulile kuze kube manje futhi uqhubeka nokuthola ikhodi ye-P0191, into yokugcina okufanele uyihlole ukuxhumana ku-PCM. Nqamula izixhumi futhi uhlole ngokucophelela amatheminali (izingxenye zensimbi) ngaphakathi kwezixhumi. Bona ukuthi zibukeka zigqwalile, zishile, noma mhlawumbe ziluhlaza uma ziqhathaniswa nombala wensimbi ojwayelekile okungenzeka ukuthi ujwayele ukuwubona.

Uma konke ukuhlolwa kudlula, kepha usathola ikhodi ye-P0191, kungenzeka ikhombise ukwehluleka kwe-PCM. Ngaphambi kokufaka i-PCM kuvunyelwe, kunconywa ukuthi wenze ukusetha kabusha okunzima (nqamula ibhethri). Kungabuye kudingeke ukuthi ufake enye inzwa yengcindezi yesitimela sikaphethiloli.

NGOKUQAPHELA! Ezinjinini zikadizili ezinamasistimu kawoyela kaloliwe ajwayelekile: uma kusolwa inzwa yomfutho wesitimela kaphethiloli, ungaba nochwepheshe abakufakela inzwa. Le nzwa ingase ifakwe ngokuhlukile noma ingaba yingxenye yesitimela sikaphethiloli. Kunoma ikuphi, umfutho wesitimela sikaphethiloli walezi zinjini zikadizili lapho ingenzi lutho ngokufudumele ngokuvamile okungenani u-2000 psi, futhi ngaphansi komthwalo ungaba ngaphezu kuka-35,000 psi. Uma ungavalwanga kahle, lo mfutho kaphethiloli ungasika isikhumba, futhi uphethiloli kadizili unamagciwane kuwo angabangela ushevu egazini.

Umakhenikha uyihlonza kanjani ikhodi ye-P0191?

• Umakhenikha uzosebenzisa isikena se-OBD-II ukuze athole idatha yozimele wokuqandisa ukuze athole ukuthi imoto yayikusiphi isimo ngenkathi i-DTC P0191 isethwa imojula yokulawula amandla (PCM).
• Iqedela idrayivu yokuhlola futhi isebenzisa idatha yesikhathi sangempela ukuze inqume ukuthi ukufundwa kwengcindezi kaphethiloli kuyinto evamile yini.
• Isebenzisa isihloli somfutho kaphethiloli ukuze inqume ukuthi kunenkinga yenzwa noma inkinga yomfutho kaphethiloli.
• Uma ukucindezela kukaphethiloli KULUNGILE, bazosebenzisa i-oscilloscope ukuze bahlole isixhumi senzwa yokucindezela kwesitimela sikaphethiloli kanye nezintambo. Inhloso yalokhu ukuqinisekisa ukuthi i-sensor circuitry iphelele.
• Inzwa cishe inephutha uma umfutho wangempela kaphethiloli ULUNGILE futhi ukujikeleza kwenzwa kuhle.

Amaphutha Avamile Lapho Uhlonza Ikhodi P0191

Iphutha elivamile lapho uxilonga i-DTC P0191 iwukuziba ezinye izingxenye ezingase zidinge ukulungiswa bese ubuyisela inzwa yomfutho wesitimela sikaphethiloli kuqala.

Izintambo ezixegayo noma eziphukile, isilawuli somfutho kaphethiloli esingalungile, noma iphampu kaphethiloli engalungile yizinto ezivame ukunganakwa lapho kuhlolwa futhi kuqedwa ukulungisa.

Ibucayi kangakanani ikhodi ye-P0191?

I-DTC P0191 ithathwa njengebucayi njengoba yaziwa ngokudala izinkinga zokushayeleka. Ukushayela ngale khodi kungase kubangele imoto ukuthi ime noma inyakaze ngenkathi ushayela. Kungase kube nokwenyuka kokusetshenziswa kukaphethiloli, okungase kubize. Kubalulekile ukuthatha le khodi ngokungathi sína futhi uyihlole futhi uyilungise ngokushesha okukhulu.

Yiziphi izilungiso ezingalungisa ikhodi P0191?

• Ukufaka esikhundleni sephampu kaphethiloli
• Ukufaka esikhundleni sesilawuli sengcindezi kaphethiloli
• Lungisa noma yiziphi izintambo eziphukile, eziphukile, noma ezimfushane eziholela kunzwa yokucindezela kukaphethiloli.
• Ukulungiswa kwesixhumi esigqwalile senzwa yokucindezela kukaphethiloli
• Ukushintshwa kwenzwa yengcindezi yamafutha
• Ukulungisa noma yikuphi ukuvuza kwevacuum enjinini

Amazwana engeziwe okufanele acatshangelwe mayelana nekhodi P0191

Ezimweni eziningi, kunezinye izingxenye ezibangela le DTC. Thatha isikhathi sakho futhi ucabange ngawo wonke amathuba ngaphambi kokuphetha ngokuthi inzwa yomfutho wesitimela sikaphethiloli ayisebenzi. Futhi, qiniseka ukuthi unamathuluzi adingekayo okuxilongwa. Uzodinga isithwebuli se-OBD-II kanye ne-oscilloscope.
