P0198 chizindikiro cha kutentha kwa injini yamafuta apamwamba

P0198 - OBD-II Mavuto Code Kufotokozera

Sensa ya kutentha kwa injini yamafuta, mulingo wapamwamba kwambiri

Kodi vuto la P0198 limatanthauza chiyani?

Khodi yamavuto iyi (DTC) imagwirizana ndi zotumizira ndipo imagwira ntchito pamagalimoto okhala ndi OBD-II monga Ford Powerstroke, Chevrolet GMC Duramax, VW, Nissan, Dodge, Jeep, Audi ndi ena. Masitepe enieni okonzekera akhoza kusiyana malinga ndi kupanga ndi chitsanzo.

Kutentha kwamafuta a injini (EOT) sensor imatumiza chizindikiro ku gawo lowongolera (PCM) pamakina amafuta, nthawi ya jakisoni komanso kuwerengera kwa pulagi. EOT imafanizidwanso ndi masensa ena a kutentha monga Intake Air Temperature (IAT) sensor ndi Engine Coolant Temperature (ECT) sensor. Masensa awa nthawi zambiri amagwiritsidwa ntchito mu injini za dizilo. Masensa a EOT amalandira magetsi kuchokera ku PCM ndikusintha kukana kutengera kutentha kwamafuta. Code P0198 imachitika pamene PCM ipeza chizindikiro chapamwamba cha EOT, chomwe nthawi zambiri chimasonyeza dera lotseguka.

Ma code ena okhudzana ndi P0195 (sensor kulephera), P0196 (masanjidwe/mavuto amachitidwe), P0197 (siginecha yotsika), ndi P0199 (sensor intermittent).

Kodi zizindikiro za P0198 ndi ziti?

Chizindikiro chokha ndichoti chowunikira cha Check Engine chayatsidwa. Dongosolo la EOT lapangidwa kuti lizindikire zovuta zina ndi galimotoyo, ndipo ngati kuzungulira kwake kumakhala kolakwika, sikungathe kuwongolera kutentha kwamafuta. Izi zimawonekera kudzera mu kuwala kwa injini (kapena kuwala kwa injini).

Kodi vuto la P0198 ndi lalikulu bwanji?

Kuopsa kwa zizindikirozi kumatha kukhala kocheperako mpaka koopsa. Nthawi zina, makamaka ngati akutsatiridwa ndi zizindikiro zokhudzana ndi kutentha kozizira, izi zikhoza kusonyeza injini yotentha kwambiri. Choncho, tikulimbikitsidwa kuthetsa zizindikirozi mwamsanga.

Zotheka

1. EOT dera lalifupi lalifupi kupita ku mphamvu
2. Powertrain control module (PCM) ndiyolakwika
3. Kutentha kwamafuta ochepa a injini
4. Mavuto ozizira pamakina
5. Mavuto a zingwe
6. Cholakwika injini kutentha kachipangizo
7. Chingwe cha sensor kutentha kwa injini ndi chotseguka kapena chachifupi.
8. Engine Mafuta Kutentha Sensor Circuit Mawaya Osauka

Kodi code P0198 imadziwika bwanji?

Kuti muzindikire kachidindo kameneka, choyamba yang'anani chithunzithunzi cha kutentha kwa mafuta a injini ndi mawaya ake kuti muwone kuwonongeka, kulumikizidwa kotayirira, kapena zovuta zina. Ngati zowonongeka zapezeka, ziyenera kukonzedwa, kenaka bwererani kachidindo ndikuwona ngati ikubwerera.

Pambuyo pake, yang'anani zolemba zaukadaulo (TSBs) zokhudzana ndi nkhaniyi. Ngati palibe ma TSB omwe apezeka, pitani ku diagnostics system pang'onopang'ono potsatira malangizo a wopanga. Yang'anani momwe makina ozizira amagwirira ntchito, kuonetsetsa kuti injiniyo imasunga kutentha koyenera.

Kenako, yesani injini ya sensor kutentha kwa sensor sensor pogwiritsa ntchito multimeter. Lumikizani ndikudula sensa ya EOT ndikuwona momwe kuwerenga kwa multimeter kusinthira. Ngati mawerengedwe asintha mwadzidzidzi, sensa imakhala yolakwika kwambiri. Ngati sichoncho, sensor iyenera kusinthidwa.

Yang'anani dera lofotokozera ma voltage: Onetsetsani kuti EOT ikulandila voliyumu yochokera ku PCM. Ngati sichoncho, yang'anani chigawo cha voltage cha reference kuti chitsegule. Kenaka, yesani dera la chizindikiro cha pansi, kuonetsetsa kuti kugwirizana kwa nthaka ku EOT ndi PCM kukugwira ntchito bwino.

Khodi iyi mwina ikuwonetsa zazifupi mudera la EOT, ndipo muyenera kuchita kafukufuku wama waya kuti mupeze ndikukonza zazifupi.

Zolakwa za matenda

• Katswiri amatha kusintha sensa popanda kuyang'ana waya kupita ndi kuchokera ku sensa ya EOT.
• Polephera kuwongolera mphamvu yamagetsi, PCM/ECM imapereka kwa sensa.
• Sizingatheke kuzindikira mavuto ena omwe angakhale akuthandizira kutentha kwa mafuta ochepa.

Kodi vuto la P0198 ndi lalikulu bwanji?

Kachidindo kameneka sikangathe kuwononga kwambiri galimoto, koma pali mwayi wochepa kuti ungayambitse mavuto. Nthawi iliyonse PCM imagwiritsa ntchito magetsi ochuluka (12,6-14,5V) kumabwalo opangidwira ma voltages otsika, imatha kuwononga. Komabe, magalimoto ambiri amakono ali ndi machitidwe opangidwa kuti ateteze ku kuwonongeka koteroko ngati magetsi akupitirira zomwe zikuyembekezeredwa.

Ndi kukonza kotani komwe kungakonze P0198?

1. Konzani mawaya owonongeka, chotsani dera lalifupi mumagetsi.
2. Konzani PCM (powertrain control module).
3. Kuthetsa vuto la otsika injini kutentha mafuta.

Kodi P0198 Engine Code ndi chiyani [Quick Guide]

P0198 KIA

Sensa ya kutentha kwa injini imagwiritsidwa ntchito poyeza kutentha kwa mafuta a injini. Sensayi imasintha magetsi ndikutumiza chizindikiro chosinthidwa ku injini yoyendetsera injini (ECM), yomwe imagwiritsidwa ntchito ngati chizindikiro chothandizira kuyeza kutentha kwa injini. Sensa imagwiritsa ntchito thermistor, yomwe imakhudzidwa ndi kusintha kwa kutentha. Mphamvu yamagetsi ya thermistor imachepa pamene kutentha kumawonjezeka.

Khodi ya P0198 ndi code yapadziko lonse lapansi yomwe imagwiritsidwa ntchito ndi opanga onse ndipo ili ndi tanthauzo lomwelo.

Wopanga aliyense amagwiritsa ntchito njira yake yodziwira kuti ayese dongosololi. Khodi iyi nthawi zambiri imagwiritsidwa ntchito m'magalimoto othamanga kwambiri omwe amapangidwira kuti aziyendetsa kwambiri. Mikhalidwe yotereyi ili kunja kwa kayendetsedwe ka kayendetsedwe kabwino, zomwe zikufotokozera chifukwa chake EOT sichigwiritsidwa ntchito m'magalimoto ambiri a tsiku ndi tsiku.
