I-P0198 Inzwa yenzwa yokushisa yenjini iphezulu

I-P0198 - I-OBD-II Ikhodi Yenkinga Incazelo Yobuchwepheshe

Inzwa yokushisa kawoyela yenjini, izinga lesiginali eliphezulu

Isho ukuthini ikhodi yenkinga P0198?

Le khodi yenkathazo (i-DTC) ihlobene nokuhanjiswa futhi isebenza ezimotweni ezihlome nge-OBD-II njengeFord Powerstroke, Chevrolet GMC Duramax, VW, Nissan, Dodge, Jeep, Audi nezinye. Izinyathelo eziqondile zokulungisa zingahluka kuye ngokwakhiwa kanye nemodeli.

Inzwa yokushisa kawoyela wenjini (i-EOT) ithumela isignali kumojula yokulawula (PCM) yesistimu kaphethiloli, isikhathi somjovo kanye nokubala kwepulaki elikhanyayo. I-EOT iphinde iqhathaniswe nezinye izinzwa zokushisa njengenzwa ye-Intake Air Temperature (IAT) kanye nenzwa ye-Engine Coolant Temperature (ECT). Lezi zinzwa zivame ukusetshenziswa ezinjinini zikadizili. Izinzwa ze-EOT zithola i-voltage ku-PCM futhi zishintsha ukumelana okusekelwe ekushiseni kwamafutha. Ikhodi P0198 yenzeka lapho i-PCM ithola isignali ephezulu ye-EOT, evame ukukhombisa isekethe evulekile.

Amanye amakhodi ahlobene ahlanganisa i-P0195 (ukwehluleka kwenzwa), i-P0196 (izinkinga zobubanzi/ukusebenza), i-P0197 (isiginali iphansi), kanye ne-P0199 (i-sensor intermittent).

Yiziphi izimpawu zekhodi ye-P0198?

Okuwukuphela kophawu ukuthi isibani se-Check Engine sivuliwe. Uhlelo lwe-EOT lwenzelwe ukubona ezinye izinkinga ngemoto, futhi uma ukujikeleza kwayo kuba nephutha, ingase ingakwazi ukulawula izinga lokushisa likawoyela. Lokhu kuzibonakalisa ngokukhanya kwenjini yokuhlola (noma ilambu lokulungisa injini).

Ibucayi kangakanani ikhodi yenkathazo P0198?

Ubunzima bala makhodi bungasukela kokumaphakathi kuye kobunzima. Kwezinye izimo, ikakhulukazi uma ehambisana namakhodi ahlobene nezinga lokushisa elipholile, lokhu kungase kubonise injini eshisa kakhulu. Ngakho-ke, kunconywa ukuxazulula la makhodi ngokushesha ngangokunokwenzeka.

Izizathu ezingenzeka

1. Isekethe ye-EOT emfushane ukuya emandleni
2. I-powertrain control module (PCM) inephutha
3. Izinga lokushisa lamafutha enjini eliphansi
4. Izinkinga zesistimu yokupholisa injini
5. Izinkinga zokufaka izintambo
6. Inzwa yokushisa kawoyela enamaphutha
7. Ihhashi lenzwa yezinga lokushisa likawoyela wenjini livuliwe noma lifushane.
8. I-Engine Oil Temperature Sensor Circuit Poor Wiring

Itholakala kanjani ikhodi P0198?

Ukuze uhlole le khodi, qala wenze ukuhlola okubonakalayo kwenzwa yezinga lokushisa likawoyela wenjini kanye nezintambo zayo ukuze ubheke umonakalo, ukuxhumeka okuxekethile, noma ezinye izinkinga. Uma umonakalo utholakala, kufanele ulungiswe, bese usetha kabusha ikhodi futhi ubone ukuthi iyabuya yini.

Ngemva kwalokho, hlola amanqampunqampu esevisi yezobuchwepheshe (TSBs) ahlobene nalolu daba. Uma awekho ama-TSB atholakele, qhubekela ekuxilongweni kwesistimu yesinyathelo nesinyathelo ulandela imiyalelo yomkhiqizi. Hlola ukusebenza kwesistimu yokupholisa, uqinisekise ukuthi injini igcina izinga lokushisa elilungile lokusebenza.

Okulandelayo, hlola isifunda senzwa yokushisa yenjini usebenzisa i-multimeter. Xhuma futhi unqamule inzwa ye-EOT futhi uhlole ukuthi ukufundwa kwe-multimeter kushintsha kanjani. Uma ukufundwa kushintsha kungazelelwe, inzwa kungenzeka ibe nephutha. Uma kungenjalo, inzwa kufanele ishintshwe.

Hlola i-voltage reference circuit: Qinisekisa ukuthi i-EOT ithola i-reference voltage kusuka ku-PCM. Uma kungenjalo, hlola i-voltage yereferensi ukuze uthole okuvuliwe. Okulandelayo, hlola isifunda sesignali yaphansi, uqinisekise ukuthi ukuxhumeka komhlabathi ku-EOT ne-PCM kusebenza kahle.

Le khodi cishe ikhombisa okufushane kusekethe ye-EOT, futhi uzodinga ukwenza ukuxilonga kwezintambo okuphelele ukuze uthole futhi ulungise okufushane.

Amaphutha okuxilonga

• Uchwepheshe angase amiselele inzwa ngaphandle kokuhlola izintambo eziya noma ezisuka kuyinzwa ye-EOT.
• Ayikwazi ukulawula i-voltage yesithenjwa, i-PCM/ECM iyinikeza inzwa.
• Akwenzeki ukuthola ezinye izinkinga ezingase zibe nomthelela emazingeni okushisa aphansi kawoyela.

Ibucayi kangakanani ikhodi yenkathazo P0198?

Le khodi mancane amathuba okuthi idale umonakalo omkhulu emotweni, kodwa mancane amathuba okuthi idale izinkinga ezithile. Noma nini lapho i-PCM isebenzisa amandla kagesi aphezulu (12,6-14,5V) kumasekhethi aklanyelwe ama-voltage aphansi, angabangela umonakalo. Nokho, izimoto eziningi zesimanje zinezinhlelo eziklanyelwe ukuvikela umonakalo onjalo uma amandla kagesi edlula lokho okulindelekile.

Ikuphi ukulungisa okuzolungisa ikhodi ye-P0198?

1. Lungisa izintambo ezilimele, susa isifunda esifushane ekunikezeni amandla.
2. Lungisa i-PCM (imojula yokulawula i-powertrain).
3. Xazulula inkinga yokushisa kwamafutha enjini ephansi.

Iyini Ikhodi Yenjini ye-P0198 [Umhlahlandlela osheshayo]

P0198 KIA

Inzwa yokushisa kawoyela yenjini isetshenziswa ukukala izinga lokushisa lamafutha enjini. Le nzwa ishintsha i-voltage bese ithumela isignali eguquliwe kumojula yokulawula injini (ECM), bese isetshenziswa njengesignali yokufaka ukukala izinga lokushisa likawoyela wenjini. Inzwa isebenzisa i-thermistor, ezwelayo ekushintsheni kwezinga lokushisa. Ukumelana nogesi kwe-thermistor kuncipha njengoba izinga lokushisa likhuphuka.

Ikhodi ye-P0198 iyikhodi yendawo yonke esetshenziswa yibo bonke abakhiqizi futhi inencazelo efanayo.

Umkhiqizi ngamunye usebenzisa indlela yakhe yokuxilonga ukuze ahlole lolu hlelo. Le khodi ivame ukusetshenziswa ezimotweni ezisebenza kahle kakhulu ezidizayinelwe izimo zokushayela ezeqisayo. Izimo ezinjalo zingaphandle kobubanzi bokushayela okuvamile, okuchaza ukuthi kungani i-EOT ingasetshenziswa ezimotweni eziningi zansuku zonke.
