Idatha ye-OBD-II DTC

I-Fuel Pressure Sensor B Circuit Out of Range / Performance

Kusho ukuthini lokhu?

Le Khodi Yezinkinga Zokuxilonga (i-DTC) yikhodi yokudlulisela ejwayelekile, okusho ukuthi isebenza ezimotweni ezihlome nge-OBD-II ezinenzwa yokucindezela uphethiloli (Chevrolet, Ford, GMC, Chrysler, Toyota, njll.). Noma kujwayelekile, izinyathelo zokulungisa ngqo zingahluka ngokuya ngokwenziwa / imodeli. Okuxakayo ukuthi le khodi ibonakala ivame kakhulu ezimotweni zeGM (GMC, Chevrolet, njll.) Futhi ingahle ihambisane nekhodi engu-P018C kanye / noma amanye amakhodi ngasikhathi sinye.

Izimoto eziningi zesimanje zine-sensor ye-fuel pressure (FPS). I-FPS ingenye yokokufaka okuyinhloko kwimodyuli yokulawula i-powertrain (PCM) yokulawula ipompo kaphethiloli kanye / noma i-injector ye-fuel.

Inzwa yokucindezela uphethiloli iwuhlobo lwenzwa ebizwa ngokuthi i-transducer. Lolu hlobo lwenzwa lushintsha ukumelana kwalo kwangaphakathi nengcindezi. I-FPS ivamise ukugxunyekwa ku-fuel rail noma kulayini kaphethiloli. Ngokuvamile kuba nezintambo ezintathu eziya ku-FPS: ireferensi, isignali kanye nomhlabathi. Inzwa ithola i-voltage eyireferensi ku-PCM (imvamisa engu-5 volts) futhi ibuyisela i-voltage yempendulo ehambisana nokucindezela kukaphethiloli.

Endabeni yale khodi, u- “B” ukhombisa ukuthi inkinga iyingxenye yochungechunge lohlelo hhayi uphawu oluthile noma ingxenye ethile.

I-P018B isethwe lapho i-PCM ithola inkinga yokusebenza ngenzwa yokucindezela komoya. Amakhodi ahlanganisiwe afaka i-P018A, P018C, P018D, ne-P018E.

Isibonelo se-Fuel pressure sensor:

Ukuqina kwekhodi nezimpawu

Ukuqina kwalawa makhodi kumaphakathi kuya kokuqina. Kwezinye izimo, lawa makhodi angabangela imoto ukuthi ingaqali. Kunconywa ukuthi ulungise le khodi ngokushesha okukhulu.

Izimpawu zekhodi yenkinga ye-P018B zingafaka:

• Hlola Injini Yokukhanya
• Injini enzima ukuqala noma engeke iqale
• Ukusebenza kabi kwenjini

Izimbangela Ezivamile Zale DTC

Izizathu ezingaba khona zale khodi zingafaka:

• Inzwa yengcindezi engaphelele
• Izinkinga zokulethwa kukaphethiloli
• Izinkinga zokufaka izintambo
• I-PCM enamaphutha

Izinqubo zokuxilonga nokulungisa

Qala ngokubheka inzwa yengcindezi kaphethiloli kanye nezintambo ezihambisanayo. Bheka ukuxhumana okuxekethile, izintambo ezilimele, njll. Uma kutholakala umonakalo, lungisa lapho kudingeka khona, sula ikhodi bese ubona ukuthi iyabuya yini. Bese ubheka ama-bulletins wensizakalo yezobuchwepheshe (ama-TSB) ukuthola inkinga. Uma kungatholakali lutho, kuzodingeka uqhubekele ekuhlolweni kwesistimu ngezinyathelo.

Okulandelayo inqubo ejwayelekile njengoba ukuhlolwa kwale khodi kwehlukile emotweni kuya emotweni. Ukuze uvivinye ngokunembile isistimu, udinga ukubhekisa kutchartchch flowchart yomkhiqizi.

Hlola izintambo

Ngaphambi kokuqhubeka, udinga ukuxhumana nemidwebo yezintambo zemboni ukuthola ukuthi yiziphi izintambo. I-Autozone inikeza imihlahlandlela yokulungisa online yamahhala yezimoto eziningi kanti i-ALLDATA inikeza ukubhaliswa kwemoto eyodwa.

Hlola ingxenye yesifunda se-voltage voltage.

Uma ukukhanyisa kwemoto kuvuliwe, sebenzisa i-multimeter yedijithali esethwe kuvoltheji ye-DC ukuze uhlole i-voltage eyireferensi (ngokuvamile engu-5 volts) esuka ku-PCM. Ukuze wenze lokhu, xhuma i-negative meter lead emhlabathini bese imitha ephozithivu iholele kutheminali yenzwa engu-B+ ohlangothini lwehhanisi lesixhumi. Uma ingekho isignali yereferensi, xhuma imitha esethwe ku-ohms (i-ignition OFF) phakathi kwetheminali ye-voltage eyireferensi kunzwa yokucindezela kukaphethiloli kanye netheminali ye-voltage eyireferensi ku-PCM. Uma ukufundwa kwemitha kuphelelwe ukubekezelelana (OL), kukhona isifunda esivulekile phakathi kwe-PCM kanye nenzwa okudingeka itholakale futhi ilungiswe. Uma isibali sifunda inani lezinombolo, kukhona ukuqhubeka.

Uma konke kuhamba kahle kuze kube manje, uzofuna ukuhlola ukuthi amandla aphuma ku-PCM. Ukuze wenze lokhu, vula i-ignition bese usetha imitha ku-voltage njalo. Xhuma umzila oqondile wemitha kutheminali ye-voltage yereferensi ye-PCM kanye nomthofu ongemuhle phansi. Uma ingekho i-voltage yereferensi evela ku-PCM, i-PCM cishe inephutha. Kodwa-ke, ama-PCM awavamile ukuhluleka, ngakho-ke kuwumqondo omuhle ukuhlola kabili umsebenzi wakho kuze kufike kulelo phuzu.

Bheka ingxenye yesifunda.

Lapho ukuthungela kwemoto KUVALIWE, sebenzisa i-resistor DMM ukuhlola ukuqhubeka komhlaba. Xhuma imitha phakathi kwetheminali yomhlabathi yesixhumi senzwa yokucindezela uphethiloli nomhlabathi we-chassis. Uma i-counter ifunda inani lezinombolo, kunokuqhubeka. Uma ukufundwa kwemitha kungaphandle kokubekezelelana (i-OL), kunesekethe evulekile phakathi kwe-PCM nenzwa edinga ukutholakala nokulungiswa.

Bheka ingxenye yesekethe yesiginali yokubuyisa.

Vala umlilo wemoto bese usetha inani lokumelana ku-multimeter. Xhuma umkhondo owodwa wokuhlola kutheminali yesignali yokubuyisela ku-PCM kanye nomunye kutheminali yokubuyisela kusixhumi senzwa. Uma inkomba ibonisa ngaphandle kobubanzi (OL), kukhona umjikelezo ovulekile phakathi kwe-PCM kanye nenzwa edinga ukulungiswa. Uma isibali sifunda inani lezinombolo, kukhona ukuqhubeka.

Qhathanisa ukufundwa kusuka kunzwa yengcindezi kaphethiloli nengcindezi yangempela kaphethiloli.

Ukuhlolwa okwenziwe kuze kube manje kukhombisa ukuthi isekhethi yesensa yengcindezi kaphethiloli ilungile. Ngemuva kwalokho uzofuna ukuhlola inzwa uqobo ngokucindezela kwangempela kaphethiloli. Ukuze wenze lokhu, qala ngokunamathisela igeji yokufaka ingcindezi kusitimela kaphethiloli. Bese uxhuma ithuluzi lokuskena emotweni bese ukhetha inketho yedatha ye-FPS ongayibuka. Qala injini ngenkathi ubuka ithuluzi lokuskena ingcindezi yangempela kaphethiloli nedatha yenzwa ye-FPS. Uma ukufundwa kungekho ngaphakathi kwe-psi embalwa yomunye nomunye, inzwa inephutha futhi kufanele ithathelwe indawo. Uma zombili lezi zifundo zingaphansi kwengcindezi ebaluliwe yomkhiqizi, i-FPS ayinaphutha. Esikhundleni salokho, kungenzeka kube nenkinga yokuphakelwa kukaphethiloli efana nepompo kagesi ehlulekile ezodinga ukuxilongwa nokulungiswa.

Izingxoxo ezihlobene ze-DTC

• Ikhodi P018B ngemva kokuhambisa inzwa yokucindezela kukaphethiloli - 2013 Camaro ZL 1I-P018B 2013 Camaro ZL1 LSA 6.2L Inzwa yengcindezi ye-Fuel isuswe kabusha ukuguqula uphethiloli we-E85, kudingeke ukuthi yelule izintambo izinyawo ezi-3 ukwamukela isihlungi sevolumu ephezulu. izintambo ezinwetshiwe zisebenzisa ukusebenza okuphezulu kwe-64 core 14ga wire wires, 1 gauge ... 

Udinga usizo olwengeziwe ngekhodi p018B?

Uma usadinga usizo nge-DTC P018B, thumela umbuzo kumazwana angezansi kwalesi sihloko.

QAPHELA. Lolu lwazi lunikezwa ngenhloso yokwaziswa kuphela. Akuhloselwe ukuthi isetshenziswe njengesincomo sokulungisa futhi asinacala nganoma yisiphi isenzo osithathayo kunoma iyiphi imoto. Yonke imininingwane ekulesi siza ivikelwe yi-copyright.
