I-P20E1 igesi engasebenzi engaguquguquki / engazinzile yokukhishwa kwengcindezi yokucindezela uketshezi

Idatha ye-OBD-II DTC

Isignali engazinzile / engazinzile kumjikelezo wenzwa yokucindezela kukaphethiloli yesistimu yokwelashwa kwegesi yokuqeda

Kusho ukuthini lokhu?

Le Khodi Yezinkinga Zokuxilonga (i-DTC) yikhodi yokudlulisela ejwayelekile futhi isebenza ezimotweni eziningi ze-OBD-II (1996 nezintsha). Lokhu kungafaka, kepha kungagcini lapho, iMercedes Benz, iMitsubishi, njll. Naphezu kohlobo olujwayelekile, izinyathelo eziqondile zokulungisa zingahluka ngokuya ngohlobo lwemodeli, ukwakheka, imodeli nokudluliswa kokuhanjiswa.

Ikhodi egciniwe ye-P20E1 emotweni yakho kadizili isho ukuthi imojula yokulawula i-powertrain (PCM) ithole i-voltage engavamile kusekethi yenzwa yomfutho kaphethiloli ngemva kokwelashwa.

Uhlelo lwe-Exhaust Aftertreatment System (olubizwa nangokuthi i-Selective Catalyst Recovery System) lusetshenziselwa ukuthuthukisa amakhono wohlelo lwegesi lokukhipha amandla. Ingaqukatha eyodwa noma eziningi zalezi zinto; idizili ye-oxidation catalyst, i-particulate filter, ukunciphisa uhlelo lokujova i-ejenti, i-ammonia slip catalyst ne-nitrogen oxide (NOx) isicupho.

Isistimu yomjovo we-reductant ngokuvamile iqukethe okungenani umjovo owodwa we-reductant, ithangi lokugcina elincishiswayo, nemigqa kaphethiloli enciphisa umfutho ophezulu. Iphampu ye-electronic high pressure ngokuvamile itholakala ethangini noma kulayini wokuphakela uphethiloli. Inzwa yokucindezela kukaphethiloli ye-EAS ivumela isilawuli ukuthi sigade ingcindezi yesistimu lapho iphampu yokuphakelayo ivuliwe. Kukulesi sekhethi lapho ukungasebenzi kahle kutholwe khona ngenkathi kugcinwa ikhodi ye-P20E1.

Phakathi kwezinye izinto, amasistimu e-exhaust gas aftertreatment systems (EAS) anesibopho sokujova i-reductant / diesel engine fluid (DEF) enhlanganisweni yamagesi e-exhaust angenhla kwesihlungi se-particulate, isicupho se-NOx kanye / noma isiguquli se-catalytic nge-automated fluid storage. nohlelo lokujova. Imijovo ebalwe ngokunembile ye-DEF inyusa izinga lokushisa lezinto ezahlukahlukene zokuhlunga futhi izenze zikwazi ukusebenza kahle. Ukwengezwa kwe-DEF ohlelweni lokuguqula amandla kunweba isikhathi sokuhlunga futhi kunciphise ukukhishwa kwamagesi ayingozi wokukhipha emkhathini.

Amasistimu we-EAS kanye nama-catalysts abhekiwe futhi alawulwa yi-PCM noma isilawuli esizimele (esixhumana ne-PCM). Isilawuli sihlola ingcindezi ohlelweni lokujova oluncishisayo, i-O2, i-NOx nezinzwa zokushisa zegesi (kanye nokunye okufakwayo) ukuthola isikhathi esifanele somjovo we-DEF (owenziwe kabusha).

Uma i-PCM ithola i-voltage engavamile kusekethe yenzwa yokucindezela kukaphethiloli ye-EAS, ikhodi ye-P20E1 izogcinwa futhi isibani senkomba yokungasebenzi singakhanya.

Buyini ubunzima bale DTC?

Ikhodi egciniwe ye-P20E1 kufanele ithathwe njengebucayi futhi ilungiswe ngokushesha okukhulu. Uhlelo lwe-EAS lungonakala ngenxa yezimo ezibe nomthelela ekuphikeleleni kwekhodi ye-P20E1.

Yiziphi ezinye zezimpawu zekhodi?

Izimpawu zekhodi yenkinga ye-P20E1 zingafaka:

• Ukunciphisa ukusebenza kwenjini
• Intuthu emnyama eyeqile ephuma ekuqothulweni kwezimoto
• Ukwehla kwamandla kaphethiloli
• Amanye amakhodi ahlobene ne-EAS / SCR

Yiziphi ezinye zezimbangela ezivamile zekhodi?

Izizathu zale khodi zingabandakanya:

• Inzwa yengcindezi engaphelele ye-EAS
• Ipompo ye-EAS enamaphutha
• Isifunda esivulekile noma esifushane sezintambo ku-EAS circuit pressure sensor sensor
• Isilawuli esibi se-EAS / PCM noma iphutha lohlelo

Yiziphi ezinye zezinyathelo ze-P20E1 zokuxazulula inkinga?

Ukuthola ikhodi ye-P20E1 kudinga isithwebuli sokuxilonga, i-digital volt / ohmmeter (i-DVOM), nomthombo wokuxilonga oqondene nemoto.

Sesha i-Technical Service Bulletin (TSB) efana nonyaka wokwenziwa, ukwenziwa nemodeli yemoto; kanye nokufuduswa kwenjini, amakhodi agciniwe, kanye nezimpawu ezitholakele kunganikeza imininingwane ewusizo yokuxilonga.

Ngithanda ukuqala ukuxilongwa kwami ​​ngokuhlola ngamehlo izintambo zokubopha ze-EAS nezixhumi. Izintambo ezishisiwe noma ezilimele kanye / noma izixhumi kufanele zilungiswe noma zifakwe esikhundleni ngaphambi kokuqhubeka.

Ngangiqhubeka ngokuxhuma isithwebuli kusixhumi sokuxilonga semoto bese ngithola wonke amakhodi agciniwe kanye nedatha yozimele efriziwe. Bhala phansi lolu lwazi ngaphambi kokusula amakhodi. Hlola ukushayela imoto kuze kube yilapho i-PCM ingena kumodi yokulungela noma ikhodi isuliwe.

Uma i-PCM ingena kumodi elungile ngalesi sikhathi, ikhodi iphakathi futhi ingaba nzima kakhulu ukuxilonga. Uma kunjalo, izimo ezibe nomthelela ekugcineni ikhodi zingadinga ukuba zimbi kakhulu ngaphambi kokuba kutholakale ukuxilongwa okunembile.

Uma ikhodi isetha kabusha ngokushesha, isinyathelo esilandelayo sokuxilonga sizodinga ukusesha umthombo wolwazi lwemoto ukuthola imidwebo yebhulokhi yokuxilonga, ama-pinout, ubuso bokuxhuma, nezinqubo zokuhlolwa kwengxenye kanye nemininingwane.

Sebenzisa i-DVOM ukuhlola (ukwehla kwamandla kagesi) kuzo zonke izizathu zohlelo lwe-EAS. Qhubeka nokuhlola ukunikezwa kwamandla wesistimu yokulawula i-EAS. Hlola amafyuzi ngesifunda esilayishiwe ukuze ugweme ukuxilongwa okungafanele.

Uma onke amafiyuzi ohlelo elungile, sebenzisa i-DVOM ukuhlola inzwa yengcindezi ye-EAS namasekethe wezinzwa. Uma enye yalezi zingxenye ingahlangabezani nemininingwane yomkhiqizi, sola ukuthi inephutha.

Udinga usizo olwengeziwe ngekhodi le-P20E1?

Uma usadinga usizo nge-DTC P20E1, thumela umbuzo wakho 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.
