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

OBD-II Dambudziko Code - P0191 - Datasheet

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

P0191 iDiagnostic Trouble Code (DTC) ye "Fuel Rail Pressure Sensor Circuit Range/Performance". Izvi zvinogona kuitika nekuda kwezvikonzero zvakati wandei uye zviri kune mechanic kuti aone kuti chii chakakonzera kodhi iyi kukonzereswa mumamiriro ako ezvinhu.

Ko dambudziko rekodhi P0191 rinorevei?

Iyi Generic Transmission / Injini DTC inowanzo shanda kune mazhinji injini jekiseni injini, ese peturu nedhiziri, kubvira 2000. Iyo kodhi inoshanda kune vese vagadziri vakaita seVolvo, Ford, GMC, VW, nezvimwe.

Iyi kodhi yakanyatso inongedzera kuchinhu chekuti chiratidzo chekupinza kubva kune peturu peturu yekunzwa sensor hachienderane neicho chinopihwa kuinjini. Uku kunogona kuve kukundikana kwemuchina kana kukundikana kwemagetsi, zvinoenderana nemugadziri wemotokari, mhando yemafuta uye system yemafuta.

Matanho ekugadzirisa matambudziko anogona kusiyana zvichienderana nemugadziri, mhando yeturu yekumanikidza system, mhando yeturu yekumanikidza sensor, uye waya tambo.

taura pfungwa. Iyi kodhi inogona kunge yakabatana ne:

• OBD-II Dambudziko Code P0171 (Fuel system yakapfuma kwazvo)
• OBD-II Dambudziko Code P0172 (Yakanyanya Kutsamira Fuel System)

Zviratidzo

Zviratidzo zveP0191 injini kodhi inogona kusanganisira:

• Chisina kushanda Chiratidzo Lamp (MIL) yakavhenekerwa
• Kushaya simba
• Injini inotanga asi haishande
• Kuderedzwa kwehupfumi hwemafuta
• Injini inogona kumira kana kuzeza
• Injini inogona kudzima kana mota yamiswa
• Kunhuhwirira kusinganzwisisiki kubva pombi yekupedza
• Hapana zviratidzo zvinoonekwa
• DTCs P0171 uye/kana P0172 dzakachengetwa mumodule yekudzora simba.

Zvikonzero zveP0191 kodhi

Zvimwe zvikonzero zvekumisikidza kodhi iyi:

• Yakakwira mafuta kumanikidza
• Low mafuta kumanikidza
• Yakakuvara FRP sensor
• Kunyanyisa kupokana mudunhu
• Vacuum leaks
• Yakadzika kana isina huni yemafuta
• Inokanganisa mafuta kumanikidza sensor
• Fuel Pressure Sensor Circuit Malfunction
• Yakanganisa mafuta anomanikidza sensor yekubatanidza
• Yakaremara mafuta kumanikidza regulator

Kuongorora uye kugadzirisa maitiro

Nzvimbo yakanaka yekutanga nguva dzose yekutarisa technical Service Bulletins (TSB) kune yako chaiyo mota. Dambudziko rako rinogona kunge riri nyaya inozivikanwa neyakagadzirwa gadziriso-yakaburitswa gadziriso uye inogona kukusevha nguva nemari panguva yekugadzirisa matambudziko.

Zvakare, neiyi chaiyo kodhi, ita shuwa kuti hauna chero pombi yemafuta / peturu zvine hukama nemodhi. Kana iwe uine mamwe makodhi anoratidza dambudziko nepombi yemafuta, tarisa kodhi iyi kutanga wozeya iyo P0191 kodhi. Kunyanya kana zvasvika padambudziko rekutanga.

Wobva watsvaga iyo peturu peturu yekunzwa sensor pane yako chaiyo mota. Inogona kutarisa chimwe chinhu seichi:

Kana uchinge waonekwa, zviongorore ongorora zvinobatanidza uye wiring. Tsvaga ma scuffs, scuffs, waya dzakafumurwa, mamaki ekupisa, kana plastiki yakaumbwa. Bvisa ma connector uye nyatsoongorora zviteshi (simbi zvikamu) mukati mezvinobatanidza. Ona kana vachitaridzika kuva noushati, kutsva, kana kuti zvimwe girini zvichienzaniswa neyakajairika simbi kara iwe yaungangodaro wajaira kuona. Kana kuchenesa kwekupedzisira kuchidiwa, unogona kutenga kuchenesa magetsi kune chero chitoro chezvikamu. Kana izvi zvisingaite, tsvaga 91% uchikwiza doro uye kapurasitiki bristle bhurasho kuti uvachenese. Wobva warega mweya waoma, tora dielectric silicone remubatanidzwa (zvakafanana zvinhu zvavanoshandisa kune vanobata girobhu uye kumutsa waya plug) uye voisa panogumira materminal.

Wobva watarisa kuti pombi yekutsvaira inobatanidza iyo sensor kune yakawanda yekudyira haisi kubuda (kana ikashandiswa). Wongorora zvese zvekubatisa hosipaipi panjanji yekumanikidza uye yekudyira yakawanda. Tsiva kana zvichidikanwa.

Kana iwe uine scan chishandiso, bvisa iyo yekunetseka matambudziko macode kubva mundangariro uye ona kana iyo kodhi inodzoka. Kana iyi isiri iyo kesi, saka panogona kunge paine chinetso chekubatanidza.

Kana iyo kodhi ikadzoka, isu tichafanirwa kuyedza iyo sensor ine michina yekumanikidza geji. Bvisa kiyi kutanga, wobva wabatanidza iyo yekumanikidza yekunzwa sensor. Wobva wabatanidza scan scan uye wotarisa kumanikidza kwemafuta pane chishandiso che scan. Batidza kiyi uye uone kumanikidza kweseji maringe nekuverenga pane chishandiso che scan. Iyo scan chishandiso uye transducer inofanira kunge iri mukati me5 psi. Inch yakaparadzana.

Kana bvunzo dzese dzapfuura kusvika zvino uye ukaramba uchiwana P0191 kodhi, chinhu chekupedzisira kutarisa kubatana muPCM. Bvisa zvibatanidza uye nyatsoongorora materminals (metal parts) mukati mezvibatanidza. Ona kana vachitaridzika seine ngura, yakatsva, kana pamwe yakasvibira kana ichienzaniswa neyakajairika simbi ruvara rwaungangove wajaira kuona.

Kana bvunzo dzese dzikapfuura, asi iwe uchiri kuwana iyo P0191 kodhi, ingangodaro inoratidza kukundikana kwePCM. Usati watsiva iyo PCM inofanirwa, zvinokurudzirwa kuti iwe uite yakaoma reset (regedza bhatiri). Izvo zvinogona zvakare kuve zvakafanira kutsiva iyo peturu njanji yekumanikidza sensor.

Yambiro! Painjini dzedhiziri dzakajairwa njanji mafuta masisitimu: kana njanji njanji yekumanikidza sensor ichifungidzirwa, unogona kuve nenyanzvi yekuisa iyo sensor yako. Iyi sensor inogona kuiswa yakaparadzana kana inogona kunge iri chikamu chechitima chemafuta. Chero zvazvingaitika, njanji yemafuta einjini dzedhiziri pakudziya isingaite inowanzoita 2000 psi, uye pasi pemutoro inogona kudarika 35,000 psi. Kana isina kuvharwa zvakanaka, iyi mafuta anomanikidza anogona kucheka ganda, uye mafuta edhiziri ane mabhakitiriya mairi anogona kukonzera chepfu muropa.

Makanika anoongorora sei kodhi yeP0191?

• Iye makanika achashandisa OBD-II scanner kuti awane kuomesa furemu data kuti aone kuti mota yanga iri papi pakaiswa DTC P0191 nepower control module (PCM).
• Inopedza bvunzo yekutyaira uye inoshandisa chaiyo-nguva data kuona kana kuverenga kwemafuta kwakajairwa.
• Inoshandisa mafuta ekumanikidza tester kuona kana paine dambudziko re sensor kana dambudziko remafuta.
• Kana kudzvanywa kwemafuta kuri OK, vanozoshandisa oscilloscope kutarisa mafuta njanji yekumanikidza sensor yekubatanidza uye wiring. Chinangwa cheizvi ndechekusimbisa kuti sensor circuitry yakamira.
• Iyo sensor ndiyo inonyanya kukanganisa kana iyo chaiyo mafuta yekumanikidza iri OK uye sensor circuitry yakanaka.

Zvakajairwa Kukanganisa Pakuongororwa Code P0191

Chikanganiso chakajairika kana uchiongorora DTC P0191 ndeye kufuratira zvimwe zvinhu zvingangoda kugadziriswa uye kutsiva mafuta njanji yekumanikidza sensor kutanga.

Waya dzisina kusimba kana dzakapwanyika, chibatiso chemafuta chakashata, kana pombi yemafuta isina kunaka zvinhu zvisingawanzo cherechedzwa pakuongorora nekupedza kugadzirisa.

Kodhi yeP0191 yakakomba zvakadii?

DTC P0191 inoonekwa seyakakomba sezvo ichizivikanwa kukonzera nyaya dzekutyaira. Kutyaira neiyi kodhi kunogona kuita kuti mota imire kana kutenderera ichityaira. Panogonawo kuwedzera kushandiswa kwemafuta, izvo zvinogona kudhura. Zvakakosha kutora iyi kodhi zvakanyanya uye kuongorora uye kuigadzirisa nekukurumidza sezvinobvira.

Ndezvipi zvinogadzirisa zvinogona kugadzirisa kodhi P0191?

• Kutsiva pombi yemafuta
• Kutsiva peturu kumanikidza gadziriro
• Gadzirisa chero waya dzakatyoka, dzakapwanyika, kana dzakapfupika dzinotungamira kuhutsi hwekunzwa.
• Kugadziriswa kwechibatanidza chine ngura kune iyo mafuta pressure sensor
• Fuel pressure sensor replacement
• Kugadzirisa chero vacuum inodonha muinjini

Mamwe makomendi ekufunga nezve kodhi P0191

Kazhinji, pane zvimwe zvikamu zvinokonzeresa DTC iyi. Tora nguva yako uye funga nezvese zvingangoitika usati wapedzisa kuti iyo mafuta njanji pressure sensor haina kukwana. Zvakare, ita shuwa kuti une maturusi akakodzera anodiwa pakuongororwa. Iwe unozoda OBD-II scanner uye oscilloscope.

Unoda rumwe rubatsiro neiyo p0191 kodhi?

Kana iwe uchiri kuda rubatsiro neDTC P0191, tumira mubvunzo mune zvakataurwa pazasi peichi chinyorwa.

ONA. Ruzivo urwu rwunopihwa nekuda kweruzivo chete. Izvo hazvina kuitirwa kushandiswa sezano rekugadzirisa uye isu hatisi mhosva kune chero chiito chaunotora pane chero mota. Ruzivo rwese pane ino saiti rwakachengetedzwa nekodzero.
