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, VW, Audi, Mercedes Benz, Ford, Mitsubishi, nezvimwewo Kunyangwe hazvo zvakasarudzika, matanho chaiwo ekugadzirisa anogona kusiyana zvichienderana nemhando yegore, gadzira, modhi uye kutamisa kwekumisikidza.

Kodhi yakachengetwa P20D7 mumotokari yako yedhiziri zvinoreva kuti iyo powertrain control module (PCM) haina kuona magetsi mune yekupedzisira kurapa mafuta kudzora wedunhu.

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.

Inodzora jekiseni system inowanzo kuve neinodzora imwe chete inodzora injector, inodzora yekuchengetera tangi, uye yakakwira yekumanikidza inoderedza mafuta mitsara. Yemagetsi yakakwira yekumanikidza pombi inowanzo kuve iri mutangi kana mune peturu yekupa mutsara. Yakanga iri mudunhu inodzora iyi yekupa pombi iyo yekuchengetedza mhosva yeP20D7 yakaonekwa.

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 jekiseni system. Majekiseni akanyatsoverengerwa eEF anosimudza tembiricha yezvinhu zvakasiyana zvesefa uye zvinoita kuti vashande zvakanyanya. Kuwedzeredzwa kweEF kune chinokonzeresa system kunowedzera hupenyu hwechinhu chesefa uye kunoderedza kuburitswa kwemagasi ekukuvadza anokuvadza mumhepo.

EAS masisitimu uye zvinokatyamadza zvinotariswa uye kudzorwa nePCM kana inomira-yega mutungamiriri (iyo inobatana nePCM). Iyo controller inoongorora kumanikidza mune inodzora jekiseni system, iyo O2, NOx uye pedza gasi tembiricha maseru (pamwe nezvimwe zvigadzirwa) kuona nguva yakakodzera yeiyo DEF (inoderedza) jekiseni.

Kana iyo PCM ikaona kushomeka kwemagetsi muEAS mafuta pombi yekudzora wedunhu, kodhi P20D7 inochengetwa uye mwenje wekusashanda ungavhenekera.

Chii chakakomba cheiyi DTC?

Iyo yakachengetwa P20D7 kodhi inofanirwa kurapwa seyakakomba uye inogadziriswa nekukurumidza sezvazvinogona. Iyo EAS system inogona kukuvara semhedzisiro yemamiriro akakonzera kuomerera kweP20D7 kodhi.

Ndezvipi zvimwe zvezviratidzo zvekodhi?

Zviratidzo zveP20D7 kodhi kodhi 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:

• Yakakanganisika EAS mafuta pombi
• Yakaremara mafuta kumanikidza sensor EAS
• Vhura kana pfupi dunhu muEAS mafuta emagetsi ekudzora wedunhu
• Haina kukwana DEF mudura reEAS
• Yakashata EAS / PCM controller kana programming kukanganisa

Ndeapi mamwe matanho ekutambudza iyo P20D7?

Kuongorora P20D7 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 iyo kodhi ikatangazve nekukasira, danho rinotevera rekuongorora rinoda kutsvaga ruzivo rwemota yekuongorora dhayigiramu yezvivharo, mapini, zviso zvekubatanidza, uye zviyero zvekuyedza uye zvirevo.

Shandisa iyo DVOM kutarisa (kudonha kwemagetsi) pane ese EAS mafuta system nzvimbo. Ramba uchiedza iyo EAS control system magetsi magetsi. Tarisa mafiyasi nedunhu rakatakudzwa kuti usazorwara zvisizvo. Kana iro chairo simba (bhatiri voltage) uye pasi maseketi akawanikwa, shandisa iyo scanner kuvhura iyo EAS mafuta pombi uye tarisa iyo control wedunhu kuburitsa voltage. Kana iyo voltage isina kukwana, tarisa EAS mafuta pombi ataure. Kana pasina magetsi ekupinza akaonekwa, fungidzira kuti mutungamiriri haana kukwana kana ane hurongwa hwehurongwa. Kana magetsi ekupinza aripo pakuregedzana asi pasina kubuda kwemagetsi kunoonekwa, fungidzira kuti iyo relay haina kunaka.

Kana iyo inobuda magetsi wedunhu reEAS magetsi iri mukati mematanho, shandisa iyo DVOM kuyedza iyo EAS peturu yekunzwa sensor uye pombi yemafuta. Kana chimwe chezvinhu izvi chikasasangana nemagadzirirwo emugadziri, fungidzira kuti chakaremara.
