P205B Reductant Tank Temperature Sensor Circuit Kunze kweRange / Performance

OBD-II DTC Dhata

Inoderedza tangi tembiricha sensor wedunhu kunze kwekuita huwandu

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 hazvingoperera kuMercedes, Sprinter, Ford, GMC, Chevrolet, nezvimwewo. Kunyange hazvo zvakajairika, matanho chaiwo ekugadzirisa anogona kusiyana zvichienderana nemhando yegore, gadzira, modhi uye kutapurirana.

Kodhi yakachengetwa P205B inoreva iyo powertrain control module (PCM) yaona isina kujairika magetsi mune inoderedza tangi tembiricha 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 nhanho yevoltage pane inodzoreredza tangi tembiricha sensor yedunhu iri kunze kwemhando, kodhi P205B ichachengetwa uye Malfunction Indicator Lamp (MIL) inogona kuvhenekerwa. Kuvhenekera kweMIL kungangoda kutenderera kwakawanda - kana kutadza.

Semuenzaniso tangi rekudzora mumiririri DEF:

Chii chakakomba cheiyi DTC?

Iyo yakachengetwa P205B kodhi inofanirwa kurapwa seyakakomba uye inofanira kugadziriswa 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 zveP205B 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 tangi tembiricha sensor isina kukwana
• Vhura kana ipfupi dunhu mune inoderedza mumiriri tangi tembiricha sensor wedunhu
• Yakashata SCR / PCM controller kana programming kukanganisa

Ndeapi mamwe matanho ekutambudza iyo P205B?

Kuti uongorore iyo P205B kodhi, iwe unozoda yekuongorora scanner, yedhijitari volt / ohmmeter (DVOM), uye sosi yemotokari-yakanangana neruzivo rwekuongorora.

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.

Shandisa iyo DVOM kuyedza iyo inoderedza tembiricha sensor zvinoenderana neyakagadzirwa magadzirirwo. Zvinhu zvinokundikana bvunzo mukati mehuwandu hwepamutemo zvinotenderwa zvinofanirwa kutariswa zvisina kukwana.

vanotsika 2

Kana iyo chaiyo yekudzikisa tembiricha iri mukati mekutaurwa, iyo P205B kodhi inochengetwa uye iyo sensor iri mubvunzo iri kushanda, shandisa iyo DVOM kuyedza iyo yekuisa uye yekubuda maseketi pakati peiyo tembiricha sensor uye PCM / SCR controller. Dzinga vatongi vese usati washandisa iyo DVOM kuyedza.

• Anodzora tembiricha yekunzwa macode anowanzo kuve akabatana neyakaremara kana isina kubviswa sensor.
