I-P2043 Circuit Reductant Sensor Circuit Out of Range / Performance

Idatha ye-OBD-II DTC

Isekhethi Yenzwa Yezinga Lokushisa Eyehlisayo Iphuma Kubanga Lokusebenza

Kusho ukuthini lokhu?

Le Khodi Yezinkinga Zokuxilonga (i-DTC) yikhodi yokudlulisela ejwayelekile futhi isebenza ezimotweni eziningi ze-OBD-II (1996 nezintsha). Lokhu kungabandakanya kepha akukhawulelwanga kwaMercedes, Sprinter, Ford, GMC, Chevrolet, njll. Ngenkathi kukonke, izinyathelo eziqondile zokulungisa zingahluka ngokuya ngemodeli yonyaka, ukwakheka, imodeli nokudluliswa kokuhanjiswa.

Ikhodi egciniwe engu-P2043 isho ukuthi imodyuli yokulawula amandla we-powertrain (PCM) ithole isilinganiso esingajwayelekile samandla kusekethe yokunciphisa inzwa yokushisa. Le khodi iboniswa kuphela ezimotweni ezinenjini ehlanzekile kadizili.

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. Inweba impilo yensiza yezinto zokuhlunga futhi isiza ekwehliseni ukukhishwa kwamagesi ayingozi wokukhipha 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 (owehlisayo). Umjovo we-Precision DEF uyadingeka ukugcina ukushisa kwegesi okukhipha ngaphakathi kwemingcele eyamukelekayo nokwandisa ukuhlunga kokungcola.

Iphampu yokunciphisa / yokuvuselela isetshenziselwa ukucindezela i-DEF ohlelweni lokunciphisa uketshezi lokusetshenziswa lapho kudingeka. I-PCM ihlola amandla empompo okuhlinzeka ngokushintshashintsha okuqhubekayo namaphesenti wokulayisha. I-PCM ibuye ibheke inzwa eyodwa noma ngaphezulu yengcindezi ohlelweni lokuhlinzeka ngokunciphisa ukuthola ukuthi kukhona yini ukuvuza kuhlelo.

Uma i-PCM ithola ileveli ye-voltage kusekethe yenzwa yezinga lokushisa enciphisayo engaphandle kobubanzi, ikhodi engu-P2043 izogcinwa futhi isibani senkomba esingasebenzi kahle (MIL) singakhanyiswa. Ukukhanyisa kwe-MIL kungase kudinge imijikelezo eminingi yokuthungela - uma kwenzeka kwehluleka.

Isibonelo setangi lokwehlisa i-ejenti DEF:

Buyini ubunzima bale DTC?

Ikhodi egcinwe ku-P2043 kufanele iphathwe ngokungathi sína futhi kufanele isingathwe 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-P2043 zingafaka:

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

Yiziphi ezinye zezimbangela ezivamile zekhodi?

Izizathu zale khodi zingabandakanya:

• Ukunciphisa inzwa yokushisa kwe-ejenti kunesici
• Isifunda esivulekile noma esifushane esifundeni kuhlelo lokunciphisa inzwa lokushisa
• Isilawuli se-SCR / PCM esingalungile noma iphutha lohlelo

Yiziphi ezinye zezinyathelo zokuxazulula inkinga nge-P2043?

Ukuhlonza ikhodi ye-P2043 kudinga isithwebuli sokuxilonga, i-digital volt / ohmmeter (i-DVOM), nomthombo wokuxilonga oqondene nemoto.

Ungasebenzisa umthombo wolwazi lwemoto yakho ukuthola i-Technical Service Bulletin (TSB) efana nonyaka wemoto yakho, ukwakheka kwayo kanye nemodeli yakho; kanye nokususwa kwenjini, amakhodi agciniwe nezimpawu ezitholakele. Uma uyithola, ingahlinzeka ngemininingwane ewusizo yokuxilonga.

Sebenzisa isithwebuli (esixhunywe kusokhethi yokuxilonga yemoto) ukuthola wonke amakhodi agciniwe kanye nedatha yozimele efriziwe. Kunconywa ukuthi ubhale phansi lolu lwazi ngaphambi kokususa amakhodi bese uhlola ukushayela imoto kuze kube yilapho i-PCM ingena kumodi elungele noma ikhodi isuliwe.

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

Uma ikhodi isethwa kabusha ngokushesha, isinyathelo esilandelayo sokuxilonga sizodinga ukuthi useshe umthombo wolwazi lwemoto yakho ukuthola imidwebo yama-block diagnostic, ama-pinout, ama-faceplates okuxhuma, nezinqubo / imininingwane yokuhlolwa kwengxenye.

Isinyathelo 1

Sebenzisa i-DVOM ukuhlola inzwa yokushisa enganciphisi ngokuya ngemininingwane yomkhiqizi. Izinto ezihluleka ukuhlolwa ngaphakathi kwemingcele ephezulu evunyelwe kufanele zithathwe njengezingenasici.

Isinyathelo 2

Uma ukushisa kwangempela okuncishisiwe kungaphakathi kokucacisiwe, ikhodi ye-P2043 igcinwa futhi inzwa okukhulunywa ngayo iyasebenza, sebenzisa i-DVOM ukuhlola amasekethe wokufaka nawokukhipha phakathi kwenzwa yokushisa nesilawuli se-PCM / SCR. Nqamula bonke abalawuli ngaphambi kokusebenzisa i-DVOM ukuhlola.

• Amakhodi wezinzwa zokushisa anciphise imvamisa ahlotshaniswa nenzwa enephutha noma enqanyuliwe.
