P2426 Inkomba ephansi yesekethe yokulawula i-valve yokupholisa yohlelo lokukhipha igesi qeda

Idatha ye-OBD-II DTC

Isiginali ephansi kusifunda sokulawula se-valve yokupholisa yohlelo lokukhipha igesi qeda

Kusho ukuthini lokhu?

Le Khodi Yezinkinga Zokuxilonga (i-DTC) iyikhodi yokudlulisela ejwayelekile futhi isebenza ezimotweni eziningi ze-OBD-II (1996 nezintsha). Lokhu kungafaka, kepha akukhawulelwe ku, i-VW, iNissan, i-Audi, i-Ford, njll. Naphezu kohlobo olujwayelekile, izinyathelo eziqondile zokulungisa zingahluka ngokuya ngohlobo lwemodeli, ukwakheka, imodeli nokudluliswa kokuhanjiswa.

Ikhodi egciniwe engu-P2426 isho ukuthi imodyuli yokulawula amandla we-powertrain (PCM) ithole i-voltage enganele kwisekethe yokulawula i-valve ye-EGR. Izinhlelo zokupholisa ze-EGR zisetshenziswa kuphela ezinjinini zikadizili.

Uhlelo lwe-EGR lwenzelwe ukubuyisela amanye amagesi e-inert exhaust ohlelweni lokungenisa izinjini, lapho luthatha indawo yomoya ohlanzekile onomoya-mpilo. Ukufaka esikhundleni segesi yokukhipha umoya ocebile nge-oxygen kunciphisa inani lezinhlayiya ze-nitrogen oxide (NOx). I-NOx ilawulwa ngumthetho wesifundazwe futhi ingesinye sezakhi zokukhishwa kwegesi eqeda u-ozone.

Izinhlelo zokupholisa ze-EGR zisetshenziselwa ukunciphisa izinga lokushisa lamagesi e-EGR ngaphambi kokungena ohlelweni lokungenisa umoya lwenjini. Uhlelo lokupholisa lwe-EGR lusebenza njenge-radiator noma i-heater core. Isipholisi senjini sivalwe ngaphakathi kwendawo efingqiwe ebekwe ukuvumela amagesi e-EGR ukuthi adlule. I-fan yokupholisa nayo kwesinye isikhathi iyasetshenziswa. I-valve yokupholisa i-EGR elawulwa ngogesi ilawula ukuhamba kokupholisa injini ku-EGR cooler ngaphansi kwezimo ezithile.

I-PCM isebenzisa okokufaka okuvela kwinzwa yokupholisa i-injini (ECT) ne-EGR cooler temperature sensor / sensors ukuthola ukuthi i-valve yokupholisa i-EGR ivula noma ivala ngasiphi isikhathi noma ngasiphi isikhathi. I-PCM ibheka i-voltage ohlelweni lokulawula i-valve yokupholisa i-EGR isikhathi ngasinye lapho kuvulwa ukhiye.

Izinzwa zokushisa ezipholile ze-EGR ne-EGR zipholisa i-PCM ngoshintsho ku-EGR cooler kanye ne-engine coolant temperature. I-PCM iqhathanisa lokhu okokufaka ukubala ukuthi uhlelo lokupholisa lwe-EGR lusebenza kahle yini. Izinzwa zokushisa zokushisa kwegesi eziphumayo zivame ukutholakala eduze kwe-valve yokukhipha igesi, kuyilapho izinzwa ze-ECT zivame ukutholakala kujeke lamanzi lasekhanda lamanzi noma ijakhethi yamanzi eningi.

Uma i-voltage yokulawula i-valve yokupholisa i-EGR iphansi kakhulu, ngaphansi kwebanga elijwayelekile elihleliwe, noma uma okokufaka okuvela kwinzwa yokushisa / izinzwa ze-EGR akufani nalezo ezivela enzwa ye-ECT, i-P2426 izogcinwa futhi isibani sesibonisi sokungasebenzi kahle singakhanyiswa .

I-valve yokukhipha igesi yokukhipha iyingxenye yohlelo lokukhishwa kabusha kwegesi:

Buyini ubunzima bale DTC?

Ikhodi egciniwe engu-P2426 isho uhlelo lwe-EGR. Akufanele ihlukaniswe njengosindayo.

Yiziphi ezinye zezimpawu zekhodi?

Izimpawu zekhodi yenkinga ye-P2426 zingafaka:

• Azikho izimpawu (ngaphandle kokugcina ikhodi)
• Ukushisa kwesilinda okwandisiwe
• Ukunciphisa ukusebenza kwephethiloli
• Amakhodi Okushisa Okushisa Kwegesi
• Amakhodi enzwa yokushisa kwenjini

Yiziphi ezinye zezimbangela ezivamile zekhodi?

Izizathu zale khodi zingabandakanya:

• Isifunda esivulekile noma esifushane ku-wiring noma izixhumi zokulawula i-valve yokukhipha igesi yokukhipha igesi
• Izinga lokupholisa injini ephansi
• Inzwa / amaphutha wokushisa wohlelo lokukhishwa kwegesi lokukhipha
• Exhaust igesi recirculation cooler ivalekile
• Ukushisa ngokweqile kwenjini
• Exhaust igesi recirculation Ukupholisa fan onesici

Yiziphi ezinye zezinyathelo zokuxazulula inkinga nge-P2426?

Isistimu yokupholisa injini kufanele igcwaliswe ezingeni elifanele ngesipholisi esifanele ngaphambi kokuqhubeka. Uma kukhona ukuvuza kwezinjini okupholisa noma injini ishisa kakhulu, kufanele ilungiswe ngaphambi kokuqhubeka nokutholakala kwe-P2426 egciniwe.

Iskena sokuxilonga, i-digital volt/ohmmeter, umthombo wolwazi lwemoto, kanye ne-infrared thermometer (ene-laser pointer) amanye amathuluzi engingawasebenzisa ukuxilonga i-P2426.

Ngingaqala ngokuhlola ngokubonakalayo izintambo nezixhumi ezihambisana nenzwa yokushisa ye-EGR kanye nenzwa ye-ECT. Amabhande asondele kakhulu emapayipini okushisa okushisayo kanye nezinqwaba kufanele ahlolwe ngokucophelela.

Xhuma isithwebuli esikhumulweni semoto sokuxilonga bese uthola wonke amakhodi agciniwe kanye nedatha yozimele efriziwe. Ngaphambi kokusula amakhodi nokuhlola imoto, ngithanda ukuqopha lolu lwazi uma kwenzeka kuvela ukuthi luyikhodi engena ngezikhathi ezithile.

Ngalesi sikhathi, eyodwa yezinto ezimbili izokwenzeka: kungaba i-PCM ingena kumodi yokulinda (awekho amakhodi agciniwe), noma i-P2426 izosulwa.

Uma i-PCM isiqala ukulungela, i-P2426 ayizinzile futhi kunzima kakhulu ukuyithola. Ezimweni eziningi, isimo kufanele sibe sibi kakhulu ngaphambi kokuba kutholakale ukuxilongwa okunembile.

Uma i-P2426 isethwe kabusha, sebenzisa ukusakazwa kwedatha yeskena ukubona idatha ye-EGR sensor sensor kanye nedatha yenzwa ye-ECT. Ukunciphisa ukusakazwa kwedatha yesithwebuli ukufaka kuphela ulwazi oludingekayo kuzoholela ekuphenduleni kwedatha ngokushesha. Uma isithwebuli sibonisa ukuthi amazinga okushisa e-EGR ne-ECT aphakathi kwemingcele eyamukelekayo, sola i-PCM enephutha noma iphutha lohlelo lwe-PCM. Lesi yisimo sakho esingahle senzeke.

Uma idatha yenzwa yokushisa ye-EGR noma idatha yesensa yokushisa epholile ingazinzi noma ingekho esimisweni, hlola inzwa / izinzwa ezihambisanayo ngokulandela izinqubo zokuhlola nezincazelo ezinikezwe kumthombo wolwazi wemoto yakho. Izinzwa ezingahlangabezani nezincazelo zomkhiqizi kufanele zithathwe njengezinenkinga.

Sebenzisa i-DVOM ukuhlola isekethe yokulawula i-valve yokupholisa i-EGR uma izinzwa zisebenza kahle. Khumbula ukuvala zonke izilawuli ezihambisanayo ngaphambi kokuhlolwa. Lungisa noma shintsha amasekethe avulekile noma afushane lapho kudingeka.

Uma yonke imijikelezo yenzwa yokulawulwa kwevalveji yokupholisa i-EGR ingashintshi, sebenzisa i-thermometer ye-infrared ukuhlola izinga lokushisa kwamagesi okukhipha lapho kutholakale khona i-EGR cooler (valve) nasendaweni yokuphuma ye-EGR cooler (lapho injini isebenza futhi izinga lokushisa elijwayelekile). Qhathanisa imiphumela etholwe nemininingwane yomkhiqizi bese ushintsha noma yiziphi izingxenye zesistimu yokupholisa i-EGR okuyiphutha njengoba kudingeka.

• Ukufaka i-aftermarket nezakhi ezisebenza kahle kakhulu zokukhishwa kwegesi kungadala ekugcineni kwe-P2426.

Udinga usizo olwengeziwe ngekhodi engu-P2426?

Uma usadinga usizo nge-DTC P2426, 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.
