Kunodzvinyirira Pressure Sensor Circuit Yakaderera

Izvi zvinorevei?

Iyi Yekuongorora Dambudziko Kodhi (DTC) ndeye yakajairika kodhi yekufambisa uye inoshanda kune mazhinji OBD-II mota (1996 uye nyowani). Izvi zvinogona kusanganisira, asi hazvirevi kune, mota dzinobva kuDodge, Ram, VW, Audi, GMC, BMW, Mercedes-Benz, Ford, Chevrolet, nezvimwe. Kunyange hazvo matanho ekugadzirisa akawandisa achisiyana zvichienderana negore remodheru, gadzira, modhi uye kutumira. kugadzirisa.

Kodhi yakachengetwa P204C inoreva iyo powertrain control module (PCM) yaona isina kukwana voltage mune inoderedza inomanikidza sensor wedunhu. Iyi kodhi inoratidzwa chete pamotokari ine yakachena dhiziri injini.

Iyo catalyst system inoitisa kudzikisira (kunyanya) zvese zvinopedza kubuda, kunyangwe mamwe mashandisirwo akave akashongedzerwa neNox musungo.

Exhaust Gesi Kutenderera (EGR) masisitimu anotora rimwe danho mukuderedza NOx emissions. Nekudaro, yanhasi makuru, enjini dzedhiziri dzine simba kwazvo hadzigone kusangana neyakaomarara federal (US) emission zviyero neEGR chete, DPF / chinogadzirisa chinogadziriswa, uye NOx musungo. Neichi chikonzero, masarudzo akasarudzika ekuderedza (SCR) akagadzirwa.

MaSCR masisitimu anopinza inodzora kudhizaina kana Diesel Exhaust Fluid (DEF) mukati memhepo yekumusoro inokwira kumusoro kweiyo firita firita, NOx musungo uye / kana chinogadzirisa chinogadzirisa kuburikidza neinodzora jekiseni revhavha (solenoid). Iyo chaiyo yakaverengerwa DEF jekiseni inokwidza tembiricha yechinhu chesefa uye ichiitendera kuti ishande zvakanyanya. Inotambanudza hupenyu hwebasa resefa zvinhu uye inobatsira kudzikisira kuburitswa kwemagasi ekukuvadza anokuvadza mumhepo. Iyo yose SCR system inodzorwa uye kuongororwa nePCM kana inomira-yega mutungamiriri (iyo inobatana nePCM). Chero zvazvingaitika, mutungamiriri anotarisa iyo O2, NOx uye yekupedza gasi tembiricha sensors (pamwe nezvimwe zvigadzirwa) kuona nguva yakakodzera yeiyo DEF (inoderedza) jekiseni. Precision DEF jekiseni inodiwa kuchengetedza iyo yekuzadza gasi tembiricha mukati meyakagamuchirwa parameter uye kugadzirisa iyo filtration yezvinosvibisa.

Iyo inodzora / yekumutsiridza pombi inoshandiswa kumanikidza iyo DEF mune inoderedza mvura sisitimu yekushandisa pazvinenge zvichidikanwa. Iyo PCM inoongorora iyo yekupa pombi voltage yeinoramba ichichinja uye mutoro muzana. Iyo PCM inoongororawo imwe kana anopfuura maseru ekumanikidza mune inodzora sisitimu yekuona kana paine kudonha musystem.

Kana iyo PCM ikaona huwandu hwemagetsi mune yakadzora tembiricha sensor wedunhu iri pazasi pemiganhu inogamuchirwa, P204C kodhi inochengetwa uye mwenje wekusashanda (MIL) unogona kuvhenekera. MIL ingangoda kuwanda kwemaitiro (nekutadza) kuvhenekera.

Semuenzaniso tangi rekudzora mumiririri DEF:

Chii chakakomba cheiyi DTC?

Iyo yakachengetwa P204C kodhi inofanirwa kurapwa seyakakomba uye inogadziriswa nekukurumidza sezvazvinogona. Iyo SCR system inogona kuve yakaremara nekuda kweizvi. Kukuvadza kweCatalyst kunogona kuitika kana iwo mamiriro akakonzera kuenderera kwekodhi asina kugadziriswa nenzira yakakodzera.

Ndezvipi zvimwe zvezviratidzo zvekodhi?

Zviratidzo zveP204C kodhi yekunetseka inogona kusanganisira:

• Yakadzikira mafuta kunyatsoshanda
• Hutsi hutema hwakawandisa kubva mumotokari chiutsi
• Yakaderedzwa injini kuita
• Mamwe macode ane chekuita neCSC

Ndezvipi zvimwe zvezvikonzero zvinowanzoitika zveiyo kodhi?

Zvikonzero zveiyi kodhi zvinogona kusanganisira:

• Kuderedza mumiriri kumanikidza sensor isina kukwana
• Vhura kana ipfupi dunhu mudunhu mune yakadzora yekumanikidza sensor system
• Yakashata SCR / PCM controller kana programming kukanganisa

Ndeapi mamwe matanho ekutambudza iyo P204C?

Kuongorora P204C kodhi kunoda yekuongorora scanner, digital volt / ohmmeter (DVOM), uye mota-yakatarisana neyekuongorora sosi.

Iwe unogona kushandisa yako mota ruzivo sosi kuti uwane technical Service Bulletin (TSB) inoenderana negore rekugadzira, kugadzira uye modhi yemota; pamwe neinjini inofamba, makodhi akachengetwa uye zviratidzo zvakaonekwa. Kana iwe ukaiwana, inogona kupa ruzivo rwakakosha rwekuongorora.

Shandisa scanner (yakabatana nesokisi rekuongorora mota) kuti utore ese macode akachengetedzwa uye inosanganisirwa dhizaini yedhata. Zvinokurudzirwa kuti unyore pasi ruzivo urwu usati wabvisa macode uye wozoedza kutyaira mota kudzamara PCM yapinda yakagadzirira modhi kana kodhi yadzimwa.

Kana iyo PCM ikapinda yakagadzirira modhi panguva ino, kodhi iri yepakati uye inogona kuve yakanyanya kunetsa kuongorora. Muchiitiko ichi, mamiriro akakonzera kuchengetedzwa kwekodhi angangoda kuwedzera kusati kwanyatso kuongororwa.

Kana iyo kodhi yadzoswazve ipapo, inotevera nhanho yekuongorora inoda kuti iwe utsvage yako mota ruzivo sosi yekuongorora ekuvharisa madhayagiramu, mapini, macomputer maficha, uye echikamu bvunzo maitiro / maratidziro.

vanotsika 1

Shandisa iyo DVOM kuyedza iyo inoderedza inomanikidza sensor zvinoenderana neyakagadzirwa magadzirirwo. Zvinhu zvisina kupasa bvunzo mukati mehuwandu hwepamutemo zvinotenderwa zvinofanirwa kutarisirwa kunge zvisina kukwana.

vanotsika 2

Kana kumanikidzwa chaiko mune reductant system kuri mukati mezvakatemwa, iyo P204C kodhi inochengetwa uye mutengesi ari mubvunzo ari kushanda, shandisa iyo DVOM kuyedza iyo yekuisa uye yekubuda maseketi pakati pekumanikidza transducer uye PCM / SCR controller. Dzinga vatongi vese usati washandisa iyo DVOM kuyedza.

• Makadhi ekudzora ekumanikidza anowanzo kupihwa kune inoderedza system pombi iri kubuda mukati, asi zadzisa kuongororwa.
