OBD-II DTC Dhata

Pedza gasi mushure mekurapa mafuta injector A wedunhu redhiyo / yakavhurika

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 Mercedes Benz, Sprinter, GMC, Chevrolet, Ford, nezvimwe. Kunyange hazvo zvakajairika, matanho chaiwo ekugadzirisa anogona kusiyana zvichienderana nemhando yegore, kugadzira, modhi uye kutapurirana.

Kana mota yako yedhiziri iine kodhi P20CB yakachengetwa, zvinoreva kuti iyo powertrain control module (PCM) haina kuona magetsi mukati mekurapa mafuta injekiseni yekudzivirira wedunhu yakasarudzwa A. ...

An Exhaust Aftertreatment System (inonziwo Selective Catalyst Recovery System) inoshandiswa kusimudzira kugona kweiyo gadziriso yekudzimisa gasi system. Inogona kuve nechimwe chete kana zvimwe zvezvinhu izvi; Diesel oxidation catalyst, particulate firita, kudzora mumiririri jekiseni system, ammonia slip catalyst uye nitrogen oxide (NOx) musungo.

Pakati pezvimwe zvinhu, pedza gasi mushure mekurapa masisitimu (EAS) ane basa rekubaya jekiseni redhizizi / dhiziri injini (DEF) mukati memhepo yekumusoro iri pamusoro peiyo firita, NOx musungo uye / uye iyo jekiseni system. Kuwedzeredzwa kweEF kune iyo catalytic system inowedzera hupenyu hwechinhu chemafirita uye inoderedza kuburitswa kwemagasi ekukuvadza anokuvadza mumhepo.

EAS masisitimu uye zvinokatyamadza zvinotariswa uye kudzorwa nePCM kana inomira-yega inodzora (iyo inobatana nePCM). Mutungamiriri anotarisa iyo O2, NOx uye pedza gasi tembiricha sensors (pamwe nezvimwe zvinowaniswa) kuona yakaringana nguva yeiyo DEF (inoderedza) jekiseni. DEF inofanirwa kubayiwa jekiseni panguva chaiyo uye kusvika padanho chairo rekuchengetedza iro gasi tembiricha mukati meyakagamuchirwa parameter uye kugadzirisa iyo filtration yezvinosvibisa.

Kana iyo PCM ikaona kushomeka kwemagetsi pane iyo EAS mafuta injekita yekudzora wedunhu, P20CB kodhi inochengetwa uye irikusashanda chiratidzo mwenje inogona kuvhenekera.

Chii chakakomba cheiyi DTC?

Iyo yakachengetwa P20CB kodhi inofanirwa kurapwa seyakakomba uye inogadziriswa nekukurumidza sezvazvinogona. Iyo EAS system inogona kukuvadzwa nekuda kwemamiriro ezvinhu akakonzera kuomerera kweP20CB kodhi.

Ndezvipi zvimwe zvezviratidzo zvekodhi?

Zviratidzo zveP20CB kodhi yekunetseka inogona kusanganisira:

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

Ndezvipi zvimwe zvezvikonzero zvinowanzoitika zveiyo kodhi?

Zvikonzero zveiyi kodhi zvinogona kusanganisira:

• Inokanganisa EAS mafuta injector
• Vhura kana pfupi dunhu muEAS mafuta ejekiseni ekudzora wedunhu
• Haina kukwana DEF mudura reEAS
• Yakashata EAS / PCM controller kana programming kukanganisa

Ndeapi mamwe matanho ekutambudza iyo P20CB?

Kuongorora P20CB kodhi kunoda yekuongorora scanner, digital volt / ohmmeter (DVOM), uye mota-yakatarisana neyekuongorora sosi.

Tsvaga yeTechnical Service Bulletin (TSB) inoenderana negore rekugadzira, kugadzira uye modhi yemotokari; pamwe neinjini yekufambisa, makodhi akachengetwa, uye zviratidzo zvakaonekwa zvinogona kupa ruzivo rwakakosha rwekuongorora.

Ini ndinoda kutanga kuongororwa kwangu nekutarisa ndichiongorora maEAS wiring matambo uye zvinongedzo. Yatsva kana yakakuvara wiring uye / kana zvinongedzo zvinofanirwa kugadziriswa kana kutsiviwa usati waenderera.

Ini ndaizoenderera nekubatanidza iyo scanner kune mota yekuongorora chinongedzo uye kutora ese akachengetwa makodhi uye inosanganisirwa kuomesa furemu data. Nyora chinyorwa cheruzivo urwu usati wabvisa macode. Kwayedza kutyaira mota kudzamara PCM yapinda yekugadzirira maitiro kana kodhi yadzimwa.

Kana iyo PCM ikapinda yakagadzirira modhi panguva ino, kodhi iri yepakati uye inogona kuve yakanyanya kunetsa kuongorora. Kana zvirizvo, mamiriro akaita kuti kodhi ichengetwe angangoda kutonyanya kusati kwanyatso kuongororwa.

Kana kodhi yacho ikachenurwa ipapo, danho rinotevera rekuongorora richada kutsvaga ruzivo rwemota yezviongororwa zvekuvhara mabhaisikopo, zvinongedzo zvekubatanidza, zviso zvekubatanidza, uye nzira dzebvunzo dzekuyera uye maratidziro. Iwe unogona zvakare kushandisa yako mota ruzivo sosi kuti uone iyo chaiyo nzvimbo yeA EAS mafuta injector.

Shandisa iyo DVOM kutarisa (kudonha kwemagetsi) magetsi emagetsi eEAS control system. Tarisa mafiyasi nedunhu rakatakudzwa kuti usazorwara zvisizvo. Kana simba rakakodzera (bhatiri voltage) uye maseketi epasi akawanikwa, shandisa scanner kumisikidza iyo EAS mafuta injector (solenoid) uye tarisa iyo control wedunhu kuburitsa voltage. Kana iyo voltage isingakwani, fungidzira mutungamiriri akaremara kana ane programming kukanganisa.

Kana iyo voltage yakabuda wedunhu iri mukati mezvakatemwa, shandisa iyo DVOM kuyedza iyo EAS mafuta injector ari mubvunzo. Kana iyo jekiseni ikasasangana nemagadzirirwo emugadziri, fungidzira kuti haina kurongeka.

• Iyo EAS mafuta jekiseni ingori solenoid-based injector inopfapfaidza reductant fluid mupombi yekuburitsa.
• Usakanganwa Ground Loops Paunenge Uchiedza Voltage Kudonha
