I-P2061 Izinga eliphezulu lokunciphisa isekhethi yokulawulwa kwepompo yomoya

Idatha ye-OBD-II DTC

I-Reductant Injection Air Pump Control Circuit Isiginali Ephakeme

Kusho ukuthini lokhu?

Le Khodi Yezinkinga Zokuxilonga (i-DTC) iyikhodi yokudlulisela ejwayelekile futhi isebenza ezimotweni eziningi ze-OBD-II (1996 nangaphezulu). Lokhu kungafaka, kepha akukhawulelwe ku, iDodge, iRam, i-Sprinter, iMercedes Benz, iFord, i-Audi, iVolkswagen, njll. Naphezu kohlobo olujwayelekile, izinyathelo zokulungisa ngqo zingahluka ngokuya ngonyaka wokwenziwa, ukwenziwa, imodeli nokulungiswa ukudluliswa.

Ikhodi egcinwe i-P2061 isho ukuthi imodyuli yokulawula amandla we-powertrain (PCM) ithole i-voltage eyeqile kumjikelezo wokulawulwa kwepompo womoya wokunciphisa umjovo. Igama elithi "vula" lingashintshwa kufakwe igama elithi "disabled".

Izinjini zikadizili ezinkudlwana, ezinamandla (ezinemvelo) zanamuhla azikwazi ukuhlangabezana nezindinganiso eziqinile ze-federal (i-US) zokukhishwa nge-EGR kuphela, isihlungi se-particulate / catalytic converter, kanye noxhaka lwe-NOx. Ngalesi sizathu, kusungulwe izinhlelo ezikhethiwe zokunciphisa (i-SCR).

Uhlelo lwe-SCR lujova ukwakheka okunganciphisi noma i-Diesel Exhaust Fluid (DEF) emagesi e-exhaust kanye nenani elichaziwe lomoya ongena ngenhla kwesihlungi se-particulate, isicupho se-NOx kanye / noma isiguquli se-catalytic nge-reductant injection valve (solenoid). Umjovo obalwa ngokunembile we-DEF / womoya uphakamisa izinga lokushisa kwento yokuhlunga futhi uyivumele ukuthi isebenze kahle. Inweba impilo yensiza yezinto zokuhlunga futhi isiza ekwehliseni ukukhishwa kwamagesi okukhipha ayingozi emkhathini. Lonke uhlelo lwe-SCR lubhekiwe futhi lulawulwa yi-PCM noma isilawuli esizimele sodwa (esisebenzisana ne-PCM). Kunoma ikuphi, isilawuli sihlola izinzwa zokushisa zegesi i-O2, NOx nokukhipha (kanye nokunye okufakwayo) ukuthola isikhathi esifanele se-DEF (esinciphisayo) nomjovo womoya. Umjovo we-Precision DEF uyadingeka ukugcina ukushisa kwegesi okukhipha ngaphakathi kwemingcele eyamukelekayo nokwenza ngcono 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 i-voltage eyeqile kusekethi yokulawula iphampu yomoya yomjovo ereductant, ikhodi P2061 izogcinwa futhi Isibani Senkomba Esingasebenzi (MIL) singakhanya. Kungase kuthathe imijikelezo embalwa yokubasa ukuze i-MIL ikhanyise - uma yehluleka.

Buyini ubunzima bale DTC?

Ikhodi egcinwe ku-P2061 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-P2061 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 i-ejenti yomshini womoya womoya kunenkinga
• Ukunciphisa i-ejenti yomjovo wompompo womoya ongaphelele
• Isifunda esivulekile noma esifushane kuketanga ohlelweni lwenzwa yomfutho womoya yomjovo we-reductant
• Isilawuli se-SCR / PCM esingalungile noma iphutha lohlelo

Yiziphi ezinye zezinyathelo zokuxazulula inkinga nge-P2061?

Qiniseka ukuthi uhlelo lokunciphisa / lokuvuselela alulahli ingcindezi (yangaphakathi noma yangaphandle). Vula ipompo ukuze wakhe ingcindezi bese uhlola uhlelo ukuthi akukho ukuvuza kwangaphandle yini. Sebenzisa isihloli sengcindezi kaphethiloli ukuqapha mathupha ingcindezi ohlelweni olunciphisayo. Bheka ipompo yokuphakelayo nombhobho wokuvuza. Uma kutholakala ukuvuza (kwangaphakathi noma kwangaphandle), kufanele kulungiswe ngaphambi kokuqhubeka nokuxilongwa.

Ukuhlonza ikhodi ye-P2061 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 amasekethe wokulawula umjovo wokunciphisa umjovo, izingxenye nezinzwa ngokuya ngemininingwane yomkhiqizi. Ama-DTC wesekethe angabangelwa izingxenye ezinamaphutha noma izinzwa. Izinzwa nezakhi ezingaphumeleli esivivinyweni ngaphakathi kwemingcele ephezulu evumelekile zizothathwa njengeziphutha.

Isinyathelo 2

Uma ingcindezi yomoya ye-reductant ingaphakathi kokucacisiwe, ikhodi ye-P0259 igcinwa futhi wonke amasekethe okuqala, izingxenye nezinzwa ziyasebenza, sebenzisa i-DVOM ukuhlola amasekethe wokufaka nawokukhipha phakathi kwezinzwa nesilawuli se-PCM / SCR. Nqamula bonke abalawuli ngaphambi kokusebenzisa i-DVOM ukuhlola.

• Amakhodi wesekethe wokulawula impompo yomoya anciphise imvamisa ahlotshaniswa namaphampu okuphakelayo anokuvuza kwangaphakathi.

Udinga usizo olwengeziwe ngekhodi engu-P2061?

Uma usadinga usizo nge-DTC P2061, 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.
