Kusho ukuthini lokhu?

Le Khodi Yezinkinga Zokuxilonga (i-DTC) yikhodi yokudlulisela ejwayelekile futhi isebenza ezimotweni eziningi ze-OBD-II (1996 nezintsha). Lokhu kungafaka, kodwa kungagcini lapho, iFord, iMercedes Benz, iSprinter, iSmart, iRam, njll. Ngokujwayelekile, izinyathelo eziqondile zokulungisa zingahluka ngokuya ngemodeli yonyaka, ukwakheka, imodeli nokudluliswa kokuhanjiswa.

Ikhodi egciniwe engu-P202E isho ukuthi imojula yokulawula i-powertrain (PCM) ithole i-voltage engavamile kusekethe yokulawula yevalvu yomjovo enciphisa ibhulokhi yenjini # 1 kanye nohlelo lokuqala lwe-Selective Catalyst Reduction (SCR). I-Bank one ibhekisela eqenjini lenjini lapho i-cylinder # 1 ikhona.

Uhlelo lwe-catalyst lubhekele ukunciphisa (ikakhulukazi) konke ukukhishwa kwe-exhaust, yize ezinye izinhlelo zokusebenza nazo zifakwe isicupho se-NOx.

Izinhlelo ze-Exhaust Gas Recirculation (EGR) zithatha esinye isinyathelo ekwehliseni ukukhishwa kwe-NOx. Kodwa-ke, izinjini zikadizili zikanamuhla ezinkulu nezinamandla kakhulu azikwazi ukuhlangabezana nezindinganiso eziqinile ze-federal (US) zokukhishwa ngohlelo lwe-EGR nje, isihlungi se-particulate / catalytic converter, kanye noxhaka lwe-NOx. Ngalesi sizathu, kusungulwe izinhlelo ezikhethiwe zokunciphisa (i-SCR).

Izinhlelo ze-SCR zifaka ukwakheka okunganciphisi noma i-Diesel Exhaust Fluid (DEF) kumagesi aqeda phezulu enhla yesihlungi sezinhlayiyana, isicupho se-NOx kanye / noma isiguquli se-catalytic nge-reductant injection valve (solenoid). Umjovo onikezwe isikhathi se-DEF uphakamisa izinga lokushisa kwento yokuhlunga futhi uyivumele ukuthi isebenze kahle. Lokhu kunweba isikhathi sokusebenza sezinto zokuhlunga futhi kusiza ukunciphisa ukukhishwa kwamagesi okukhipha ayingozi emkhathini.

Uhlelo lonke lwe-SCR lulawulwa futhi luqashwe yi-PCM noma isilawuli esizimele (esisebenzisana ne-PCM). Kunoma ikuphi, isilawuli sihlola izinzwa ze-O2, NOx nezokushisa kwegesi (kanye nokunye okufakwayo) ukuthola isikhathi esifanele somjovo we-DEF (owenziwe kabusha). Umjovo we-Precision DEF uyadingeka ukugcina ukushisa kwegesi okukhipha ngaphakathi kwemingcele eyamukelekayo nokwandisa ukuhlunga kokungcola.

Kusetshenziswa ama-heater ejenti anciphisa ukuvimbela uketshezi lwenjini yedizili ekuqandeni emazingeni okushisa aphezulu. Lezi zifudumezi zivame ukutholakala echibini le-DEF kanye / noma ku-hose (s) yokuhlinzekwa kombhobho wokunciphisa i-ejenti.

Uma i-PCM ithola i-voltage kusekethe yokulawula yevalvu yomjovo edonsela phansi engaphandle kwebanga elijwayelekile noma imingcele yokusebenza yebhulokhi 1 yenjini, ikhodi ye-P1E izogcinwa futhi isibani senkomba engasebenzi kahle singakhanya.

Buyini ubunzima bale DTC?

Ikhodi egciniwe ye-P202E kufanele iphathwe ngokungathi sína futhi ilungiswe ngokushesha okukhulu. Uhlelo lwe-SCR lungakhubazeka ngenxa yalokhu. Ukulimala kweCatalyst kungenzeka uma izimo ezibe nomthelela ekuphikeleni kwekhodi zingalungiswa ngesikhathi esifanele.

Yiziphi ezinye zezimpawu zekhodi?

Izimpawu zekhodi yenkinga ye-P202E zingafaka:

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

Yiziphi ezinye zezimbangela ezivamile zekhodi?

Izizathu zale khodi zingabandakanya:

• I-valve yokunciphisa umjovo engalungile
• Isifunda esivulekile noma esifushane kusifunda sokunciphisa i-ejenti yokulawula i-valve
• I-DEF enganele ethangini
• Isilawuli se-SCR / PCM esingalungile noma iphutha lohlelo

Yiziphi ezinye zezinyathelo zokuxazulula inkinga i-P202E?

Ukuze uhlole ikhodi ye-P202E, uzodinga ukufinyelela kusikena sokuxilonga, i-digital volt/ohmmeter (DVOM), kanye nomthombo wolwazi lokuxilonga oluqondene nemoto.

Uma ungathola i-Technical Service Bulletin (TSB) ehambelana nonyaka wokwenza, yenza nemodeli yemoto; kanye nokufuduswa kwenjini, ikhodi / amakhodi agciniwe kanye nezimpawu ezitholakele, kunganikeza imininingwane ewusizo yokuxilonga.

Kufanele uqale ukuxilonga ngokuhlola ngokubonakalayo ama-harnesses kanye nezixhumi zohlelo lwe-heater olunciphisayo. Izintambo ezishisiwe noma ezilimele kanye / noma izixhumi kufanele zilungiswe noma zifakwe esikhundleni ngaphambi kokuqhubeka.

Bese uxhuma isithwebuli kusokhethi yokuxilonga imoto bese ubuyisa wonke amakhodi agciniwe kanye nemininingwane yoqweqwe oluhambisanayo. Bhala lolu lwazi ngaphambi kokusula amakhodi bese uhlola ukushayela imoto kuze kube yilapho i-PCM ingena kumodi elungele noma ikhodi isethwe kabusha.

Ikhodi iphakathi futhi ingaba nzima kakhulu ukuxilonga (njengamanje) uma i-PCM ingena kumodi elungele. Kulokhu, izimo ezibe nomthelela ekugcineni ikhodi zingadinga ukuba zimbi kakhulu ngaphambi kokuba kutholakale ukuxilongwa okunembile.

Uma ikhodi isethwa kabusha, sesha umthombo wolwazi lwemoto yakho ukuthola imidwebo yama-diagnostic block, ama-pinouts wokuxhuma, ukubukwa kobuso bokuxhuma, nezinqubo zokuhlolwa kwengxenye nezinto ezithile. Uzodinga lolu lwazi ukuqedela isinyathelo esilandelayo ekuhlolweni kwakho.

Sebenzisa i-DVOM ukuhlola ukunikezwa kwamandla kohlelo lokulawula i-SCR. Hlola amafyuzi ngesifunda esilayishiwe ukuze ugweme ukuxilongwa okungafanele. Uma kutholakala amandla afanele (amandla webhethri) namasekethe angaphansi komhlaba, sebenzisa isithwebuli ukwenza kusebenze i-valve ye-injector (i-solenoid) enqamulelayo futhi uhlole amandla okukhipha wesekethe yokulawula. Uma i-voltage inganele, sola ukuthi isilawuli sinesici noma sinephutha lohlelo.

Uma isekethe lokukhipha i-voltage liphakathi kokucacisiwe, sebenzisa i-DVOM ukuhlola i-valve yokunciphisa umjovo okukhulunywa ngayo. Uma i-valve ingahlangabezani nezincazelo zomkhiqizi, kusolwa ukuthi yehlulekile.

• Ivelufa yomjovo onciphisayo empeleni ingu-injector osuselwa ku-solenoid ofafaza ukunciphisa uketshezi kumbhobho wokukhipha.

Udinga usizo olwengeziwe ngekhodi le-P202E?

Uma usadinga usizo nge-DTC P202E, 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.
