P0198 Injini yemafuta tembiricha sensor chiratidzo chakakwira

P0198 - OBD-II Dambudziko Code Unyanzvi Tsananguro

Injini yemafuta tembiricha sensor, yakakwirira chiratidzo nhanho

Ko dambudziko rekodhi P0198 rinorevei?

Iyi dambudziko kodhi (DTC) ine chekuita nekutapurirana uye inoshanda kumotokari dzine OBD-II dzakaita seFord Powerstroke, Chevrolet GMC Duramax, VW, Nissan, Dodge, Jeep, Audi nevamwe. Matanho chaiwo ekugadzirisa anogona kusiyana zvichienderana nekugadzira uye modhi.

Iyo injini yemafuta tembiricha (EOT) sensor inotumira chiratidzo kune control module (PCM) yehuti system, jekiseni nguva uye inopenya plug kuverenga. EOT inofananidzwawo nemamwe ma sensor tembiricha akadai seIntake Air Temperature (IAT) sensor uye Injini Inotonhorera Temperature (ECT) sensor. Aya ma sensors anowanzoshandiswa mumajini edhiziri. EOT sensors inogamuchira voltage kubva kuPCM uye inoshandura kuramba zvichienderana nekupisa kwemafuta. Code P0198 inoitika apo PCM inoona chiratidzo cheEOT chepamusoro, icho chinowanzoratidza dunhu rakavhurika.

Mamwe macode ane hukama anosanganisira P0195 (sensor kutadza), P0196 (matambudziko emhando/kuita), P0197 (signal low), uye P0199 (sensor intermittent).

Ndezvipi zviratidzo zveP0198 kodhi?

Chiratidzo chete ndechekuti Cheki Engine mwenje wakabatidzwa. Iyo EOT system yakagadzirirwa kuona mamwe matambudziko nemotokari, uye kana dunhu rayo rikatadza, inogona kusakwanisa kudzora tembiricha yemafuta. Izvi zvinozviratidza kuburikidza necheki injini chiedza (kana injini yekugadzirisa chiedza).

Yakakomba sei dambudziko rekodhi P0198?

Kuoma kweaya macode kunogona kubva pakati nepakati kusvika kune yakaoma. Mune mamwe mamiriro ezvinhu, kunyanya kana akaperekedzwa nemakodhi ane hukama neinotonhorera tembiricha, izvi zvinogona kuratidza injini yekupisa. Naizvozvo, zvinokurudzirwa kugadzirisa makodhi aya nekukurumidza sezvinobvira.

Zvimwe zvinokonzera

1. EOT redunhu pfupi dunhu kune simba
2. Iyo powertrain control module (PCM) ine mhosva
3. Yakaderera injini yemafuta tembiricha
4. Injini kutonhora system matambudziko
5. Matambudziko eWiring
6. Inokanganisa injini yekushisa tembiricha
7. Injini yemafuta tembiricha sensor harness yakavhurika kana kupfupika.
8. Injini Yemafuta Tembiricha Sensor Circuit Yakashata Wiring

Kodhi P0198 inoongororwa sei?

Kuti uongorore iyi kodhi, tanga waita ongororo yekuona injini yekushisa tembiricha sensor uye wiring yayo yekutarisa kukuvadzwa, yakasununguka kubatana, kana mamwe matambudziko. Kana kukanganisa kunowanikwa, kunofanira kugadziriswa, wozogadzirisazve code uye ona kana ichidzoka.

Mushure meizvozvo, tarisa kune technical service bulletins (TSBs) ine chekuita nenyaya iyi. Kana pasina maTSB awanikwa, enda kune nhanho-ne-nhanho system diagnostics uchitevera mirairo yemugadziri. Tarisa kushanda kweiyo inotonhorera system, kuve nechokwadi chekuti injini inochengetedza tembiricha yekushanda.

Tevere, edza injini yemafuta tembiricha sensor wedunhu uchishandisa multimeter. Batanidza uye bvisa iyo EOT sensor uye tarisa kuti iyo multimeter kuverenga inoshanduka sei. Kana kuverenga kwakangoerekana kwachinja, sensor inogona kunge yakanganisa. Kana zvisina kudaro, sensor inofanira kutsiviwa.

Tarisa voltage referensi redunhu: Ita shuwa kuti EOT iri kugamuchira referensi voltage kubva kuPCM. Kana zvisiri, tarisa referensi voltage wedunhu kune yakavhurika. Tevere, edzai dunhu rechiratidzo chepasi, kuve nechokwadi kuti kubatana kwepasi kuEOT nePCM kuri kushanda nemazvo.

Iyi kodhi inogona kunge inoratidza ipfupi mudunhu reEOT, uye iwe uchafanirwa kuita yakakwana wiring diagnostic kuti uwane uye kugadzirisa iyo pfupi.

Zvikanganiso zvekuongorora

• Nyanzvi inogona kutsiva iyo sensor pasina kutarisa wiring kuenda uye kubva kuEOT sensor.
• Kutadza kudzora referensi voltage, iyo PCM/ECM inoipa kune sensor.
• Hazvibviri kuona mamwe matambudziko angave ari kukonzera kuderera kwekushisa kwemafuta.

Yakakomba sei dambudziko rekodhi P0198?

Iyi kodhi haigone kukonzera kukanganisa kwakanyanya kumotokari, asi pane mukana mudiki wekuti unogona kukonzera mamwe matambudziko. Chero nguva iyo PCM inoshandisa yakanyanya voltage (12,6-14,5V) kumaseketi akagadzirirwa kuderera kwemagetsi, inogona kukuvadza. Nekudaro, mota zhinji dzemazuvano dzine masisitimu akagadzirirwa kudzivirira kubva mukukuvadzwa kwakadaro kana magetsi akadarika zvinotarisirwa.

Ndekupi kugadzirisa kuchagadzirisa kodhi P0198?

1. Gadzirisa wiring yakakanganiswa, bvisa pfupi pfupi mumagetsi emagetsi.
2. Gadzirisa iyo PCM (powertrain control module).
3. Gadzirisa dambudziko rekushomeka kwemafuta enjini.

Chii chinonzi P0198 Injini Kodhi [Kurumidza Kutungamira]

P0198 KIA

Injini yemafuta tembiricha sensor inoshandiswa kuyera tembiricha yemafuta einjini. Iyi sensor inoshandura voltage uye inotumira chiratidzo chakagadziridzwa kune injini yekudzora module (ECM), iyo inobva yashandiswa sechiratidzo chekuisa kuyera kupisa kweinjini. Iyo sensor inoshandisa thermistor, iyo inonzwa nekushanduka kwekushisa. Kuramba kwemagetsi kwe thermistor kunoderera sezvo tembiricha inowedzera.

Iyo P0198 kodhi ikodhi yepasirese iyo inoshandiswa nevagadziri vese uye ine dudziro yakafanana.

Mumwe nemumwe anogadzira anoshandisa nzira yake yekuongorora kuyedza iyi system. Iyi kodhi inowanzo shandiswa mumotokari dzepamusoro dzakagadzirirwa mamiriro ekutyaira zvakanyanya. Mamiriro akadaro ari kunze kwechiyero chekutyaira kwakajairika, izvo zvinotsanangura kuti nei EOT isingashandiswe mumotokari zhinji dzemazuva ese.
