P049E EGR B Indawo Yokulawula Idlula Umkhawulo Wokufunda

P049E EGR B Indawo Yokulawula Idlula Umkhawulo Wokufunda

Idatha ye-OBD-II DTC

Isilawuli se-Exhaust Gas Recirculation Control Isikhundla B Seqa Umkhawulo Wokufundisa

Kusho ukuthini lokhu?

Le yikhodi yenkinga yokuxilonga yokudlulisa ejwayelekile (DTC) futhi isetshenziswa kakhulu ezimotweni ze-OBD-II ezine-Exhaust Gas Recirculation (EGR) system. Lokhu kungafaka, kepha kungagcini lapho, izimoto ezivela eDodge / Ram (Cummins), Chevy / GMC (Duramax), Honda, Jeep, Hyundai, njll.

Yize kuvamile, izinyathelo eziqondile zokulungisa zingahluka ngokuya ngemodeli yonyaka, ukwakheka, imodeli, nokucushwa kokudluliswa.

Uma imoto yakho ene-OBD-II ifake ikhodi engu-P049E, kusho ukuthi imodyuli yokulawula amandla we-powertrain (PCM) ithole ukungasebenzi kahle endaweni ethile yokuhlolwa kwe-valve yegesi yokukhipha igesi ephansi (EGR). I-B ibhekisa endaweni ethile ye-valve esezansi ye-EGR.

Isistimu ye-valve yokukhipha igesi yokukhipha igesi eqediwe yakhelwe ukondla ingxenye yamagesi okukhipha abuyele emuva ezingeni lokungenisa ngokungeziwe ukuze angashiswa okwesibili. Le nqubo ibalulekile ekwehliseni inani lezinhlayiya ze-nitrous oxide (NOx) ezikhishelwa emkhathini njengomphumela ohlangothini wokushisa kwangaphakathi nokusebenza kwenjini kadizili. I-NOx kukholakala ukuthi inomthelela ekuncipheni kwe-ozone kusuka ekuqothulweni kwe-exhaust. Ukukhishwa kwe-NOx okuvela ezimotweni eziseNyakatho Melika kungaphansi komthethonqubo wenhlangano.

Umkhawulo wokufunda idigri ehleliwe ebonisa ubuncane namapharamitha aphezulu indawo ethile (B) ye-valve yokuya phansi ye-EGR engakwazi ukuzivumelanisa nayo. Uma i-PCM ithola ukuthi indawo yangempela ye-valve ye-EGR ingaphandle kwalawa mapharamitha, ikhodi ye-P049E izogcinwa futhi isibani senkomba esingasebenzi kahle (MIL) singase sivele. Kwezinye izimoto, kuthatha imijikelezo embalwa yokuthungela (ngokwehluleka) ukwenza i-MIL isebenze.

Buyini ubunzima bale DTC?

Njengoba ikhodi ye-P049E ihlobene nohlelo lwe-EGR, akufanele ithathwe njengebucayi.

Yiziphi ezinye zezimpawu zekhodi?

Izimpawu zekhodi yenkinga ye-P049E zingafaka:

• Cishe, ngeke kube khona zimpawu ngale khodi.
• Kanciphise ukusebenza kwephethiloli kancane
• Izingqinamba zokuphatha ezingenzeka

Yiziphi ezinye zezimbangela ezivamile zekhodi?

Izizathu zale khodi ye-P049E EGR zingafaka:

• Iphutha lokukhipha igesi kabusha
• Inzwa yokukhipha igesi yokukhipha ayisebenzi
• Iphutha lokuhlela le-PCM elibi

Yiziphi ezinye zezinyathelo zokuxazulula inkinga i-P049E?

Imvamisa ngiqala ukuxilongwa ngokuthola isixhumi sokuxilonga semoto nokubuyisa wonke amakhodi agciniwe nedatha ehambisanayo. Ngingalubhala lonke lolu lwazi phansi uma kwenzeka ngiludinga njengoba ukuxilongwa kwami ​​kuqhubeka. Ngemuva kwalokho ngangihlola ukushayela imoto ukubona ukuthi ikhodi isetha kabusha ngokushesha.

Ngokusesha i-Vehicle Technical Service Bulletins (i-TSB) kokufakiwe okufana nemoto, amakhodi agciniwe, nezimpawu ezibonisiwe, ungathola isisombululo ekuhlolweni kwakho (okungenzeka kube nzima). Njengoba amarekhodi e-TSB atholwe ezinkulungwaneni zochwepheshe bokulungisa, imvamisa aqukethe imininingwane ewusizo kakhulu.

Uma i-P049E igcinwa ngemuva kokusula amakhodi, ngizoba nokufinyelela kuskena sokuxilonga, i-digital volt / ohmmeter (i-DVOM), nomthombo othembekile wolwazi lwemoto.

Manje sengizokwenza ukuhlolwa okubonakalayo kwe-valve ye-EGR nayo yonke intambo nezixhumi ezihambisanayo. Gxila ezintanjeni zocingo ezihanjiswa eduze kwezinto zokuphuma ezishisayo kanye nemiphetho enejagged evame ukuhlotshaniswa nezihlangu ze-exhaust.

QAPHELA: Nqamula bonke abalawuli abahlobene kusuka kusifunda ngaphambi kokuhlola ukumelana / ukuqhubeka ne-DVOM.

Usebenzisa imidwebo yezintambo namaphini wokuxhuma atholakala emthonjeni wolwazi lwemoto yakho, hlola isekhethi ngalinye lesekhethi legesi (ne-DVOM) lesiginali. Kungadingeka ukwenza kusebenze ngesandla uhlelo lwe-EGR usebenzisa isithwebuli, njengoba amasistimu amaningi adinga isivinini sokusetha ngaphambi kokuqalisa okuzenzakalelayo. Amasekethe angahlangabezani nezincazelo zomkhiqizi azodinga ukulandelelwa abuyele emthonjeni wawo (imvamisa isixhumi se-PCM) futhi ahlolwe kabusha. Uma kungatholakali siginali ephuma ku-PCM, sola i-PCM enephutha noma iphutha lokuhlela le-PCM. Esikhundleni salokho, lungisa noma ubeke amanye amasekethe avulekile / amafushane njengoba kudingeka.

Sebenzisa i-DVOM ukuhlola i-valve yangempela ye-EGR nezinzwa ezakhelwe ngaphakathi uma wonke amasekethe engaphakathi kokucacisiwe komkhiqizi. Umthombo wolwazi lwemoto yakho uzophinda unikeze imininingwane yokuhlola le ngxenye. Uma i-exhaust gas recirculation yokwehlisa i-valve nazo zonke izinzwa (ezakhelwe ngaphakathi) zingahlangabezani nemininingwane yomkhiqizi, zisola ukuthi inephutha.

Le khodi kufanele iboniswe kuphela ezimotweni ezifakwe i-valve yokukhipha igesi yokukhipha igesi.

Udinga usizo olwengeziwe ngekhodi le-P049E?

Uma usadinga usizo nge-DTC P049E, 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.
