OBD-II DTC Dhata

Inoderedza Injection Valve Dunhu / Yakavhurika Block 2, Bank 2

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 hazvingogumiri ku, Ford, Mercedes Benz, Sprinter, Smart, Ram, nezvimwe. Kunyange hazvo zvakajairika, matanho chaiwo ekugadzirisa anogona kusiyana zvichienderana nemhando yegore, gadzira, modhi uye kutapurirana.

Kodhi yakachengetwa P2056 inoreva iyo powertrain control module (PCM) haina kuona voltage padunhu rekudzora yeiyo inodzora jekiseni vharuvhu yeinjini block mbiri uye inosarudza catalyst kupora (SCR) system yechipiri. Bhangi 2 inoreva boka reinjini iro RISINA cylinder nhamba yekutanga. Bvisa 2 inoratidza kuti akawanda anoderedza majekiseni masisitimu kana masystem eSCR ari kushandiswa.

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. Izvi zvinowedzera hupenyu hwebasa rezvisefa zvinhu uye zvinobatsira kudzikisira kuburitswa kwemagasi ekukuvadza anokuvadza mumhepo.

Iyo yese SCR system inodzorwa uye kuongororwa nePCM kana inomira-yega mutongi (iyo inobatana nePCM). Chero zvazvingaitika, mutungamiriri anotarisa iyo O2, NOx uye yekupedza gasi tembiricha maseru (pamwe nezvimwe zvigadzirwa) kuona nguva yakakodzera yeiyo DEF (inoderedza) jekiseni. Precision DEF jekiseni inodiwa kuchengetedza iyo yekuzadza gasi tembiricha mukati inogamuchirwa parameter uye kugadzirisa iyo kusefa kwekusvibisa.

Kuderedza zvinoshandiswa mumiririri zvinopisa zvinoshandiswa kudzivirira injini yedhiziri kupedza chiutsi kubva kuchando patembiricha yakanyanyisa. Aya mahedzi anowanzo kuwanikwa munzvimbo yeDEF uye / kana mune hosipaipi (s) yekudzikisa mumiririri wemuromo.

Kana iyo PCM ikaona kushomeka kwemagetsi mudunhu rekudzora kweiyo inoderedza jekiseni vharuvhu yeinjini block mbiri, block mbiri, P2056 kodhi inochengetwa uye mwenje wekusashanda ungavhenekera.

Chii chakakomba cheiyi DTC?

Kodhi yakachengetwa P2056 kodhi inofanirwa kurapwa seyakakomba uye inofanira kugadziriswa nekukurumidza sezvazvinogona. Iyo SCR system inogona kuve yakaremara nekuda kweizvi. Catalyst kukuvara kunogona kuitika kana iwo mamiriro akakonzera kuenderera kwekodhi isina kugadziriswa nenzira yakakodzera.

Ndezvipi zvimwe zvezviratidzo zvekodhi?

Zviratidzo zveP2056 kodhi kodhi inogona kusanganisira:

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

Ndezvipi zvimwe zvezvikonzero zvinowanzoitika zveiyo kodhi?

Zvikonzero zveiyi kodhi zvinogona kusanganisira:

• Yakashata inodzora jekiseni vharafu
• Vhura kana ipfupi dunhu mune inoderedza mumiririri jekiseni vharuvhu yekudzora wedunhu
• Haina kukwana DEF mutangi
• Yakashata SCR / PCM controller kana programming kukanganisa

Ndeapi mamwe matanho ekutambudza iyo P2056?

Kuti uongorore iyo P2056 kodhi, iwe unozoda kuwana kune yekuongorora scanner, digital volt / ohmmeter (DVOM), uye mota-yakatarwa yekuongorora ruzivo sosi.

Kana iwe uchikwanisa kuwana technical Service Bulletin (TSB) inoenderana negore rekugadzira, gadzira uye modhi yemota; pamwe neinjini yekufambisa, yakachengetwa kodhi / makodhi uye zviratidzo zvakawanikwa, inogona kupa ruzivo rwakakosha rwekuongorora.

Iwe unofanirwa kutanga kuongororwa pamwe nekuona nekuona harnesses uye zvinongedzo zveiyo inoderedza hita system. Yatsva kana yakakuvara wiring uye / kana zvinongedzo zvinofanirwa kugadziriswa kana kutsiviwa usati waenderera.

Wobva wabatanidza iyo scanner kune iyo mota yekuongorora socket uye unotora ese akachengetwa makodhi uye inoenderana kuomesa furemu data. Nyora chinyorwa cheruzivo urwu usati wabvisa makodhi uye bvunzo kutyaira mota kusvikira iyo PCM yapinda yakagadzirira modhi kana kodhi yadzoswazve.

Iyo kodhi iri yepakati uye inogona kuve yakanyanya kuoma kuongorora (parizvino) kana PCM ikaenda yakagadzirira modhi. Muchiitiko ichi, mamiriro akakonzera kuchengetedzwa kwekodhi angangoda kuwedzera kusati kwanyatso kuongororwa.

Kana iyo kodhi ikatangazve, tsvaga yako mota ruzivo sosi yekuongorora ekuvharisa madhayagiramu, chinongedzo pinouts, chinongedzo kumeso kutarira, uye chikamu chekuyedza maitiro uye maratidziro. Iwe uchazoda ruzivo urwu kuti upedze nhanho inotevera mune yako kuongororwa.

Shandisa DVOM kutarisa magetsi emagetsi eSCR control system. Tarisa mafiyasi nedunhu rakatakurwa kuti usazorwara zvisizvo. Kana iro simba chairo (bhatiri voltage) uye maseketi epasi akawanikwa, shandisa iyo scanner kumisikidza iyo inodzora injector vharuvhu (solenoid) uye tarisa iyo control wedunhu kuburitsa voltage. Kana iyo voltage isingakwani, fungidzira mutungamiriri akaremara kana ane programming kukanganisa.

Kana iyo inobuda magetsi wedunhu iri mukati mezvakatemwa, shandisa iyo DVOM kuyedza iyo inoderedza jekiseni vharuvhu iri mubvunzo. Kana iyo vharafu ikasasangana nemagadzirirwo emugadziri, zvinofungidzirwa kuti yakundikana.

• Iyo inodzora jekiseni vharuvhu ingori solenoid-based injector iyo inosvina ichideredza mvura inoyerera mupombi yekuzadza.
