Zvinorevei P2249?

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 kuHonda, Ford, Mazda, VW, Mercedes-Benz, Audi, Hyundai, Acura, BMW, nezvimwe. Kunyangwe hazvo zvakasarudzika, matanho chaiwo ekugadzirisa anogona kusiyana zvichienderana negore Yekugadzira. maronda, mamodheru uye kutumira. kugadzirisa.

Kodhi yakachengetwa P2249 inoreva iyo powertrain control module (PCM) yaona yakaderera referensi voltage yeiyo yepamusoro O2 sensor yeinjini block 1. Sensor 2 inoreva kune yekumusoro sensor uye block XNUMX inoreva kune injini block iyo isina cylinder nhamba yekutanga.

Injini mweya-peturu reshiyo yeinjini yega yega mutsara unotariswa nePCM uchishandisa data kubva kunopisa kupisa maseru sensors. Yese okisijeni sensor inovakwa ichishandisa zirconia yekuona chinhu chiri pakati penzvimbo yesimbi dzimba. Tudiki emagetsi (kazhinji platinamu) anonamira yekunzwa chinhu kune tambo mune yeoksijeni sensor sunga chinobatanidza, uye chinongedzo chinobatana kune controller network (CAN) iyo inobatanidza iyo oxygen sensor harness kune iyo PCM yekubatanidza.

Yese okisijeni sensor inokwenenzverwa (kana kumonyaniswa) mupombi yekuzadza. Yakamira kuitira kuti chinhu chekunzwa chiri padyo nepakati pombi. Kana gasi rekutsvaira gasi rasiya kamuri rinotsva (kuburikidza nekuwandisa kwakasiyana) uye richipfuura neiyo nzira yekuzadza (kusanganisira zvinoshandura zvinoshandura), ivo vanopfuura nemumaseru sensors. Gasi rekudzimisa rinopinda mukati memhepo yeoksijeni kuburikidza neakagadzirirwa mweya magemenzi mudzimba dzesimbi uye anotenderera akatenderedza sensor element. Mhepo inotenderera inokwezva inokweverwa kuburikidza netambo mumakamuri e sensor, kwaanozadza kamuri diki iri pakati. Ipapo mweya (mukamuri diki) unopisa. Izvi zvinokonzeresa kuti ioni yeoksijeni ibudise simba, iro rinozivikanwa nePCM semagetsi.

Musiyano uripo pakati pehuwandu hweiyoni yeion oxygen mumhepo yakatenderedza (yakadhonzwa mukati meiyo O2 sensor) uye nhamba yemakemikari mamorekuru mune yekuzadza anokonzera maoxygen ions mukati meiyo O2 sensor kuti ikurumidze uye nepakati nepakati kusimuka kubva kune imwe platinamu kune imwe. ... Sezvo ioni yeoksijeni inodhonha ichifamba pakati pezvikamu zveplatinamu, mweya unobuda weiyo oxygen sensor inoshanduka. Iyo PCM inoona shanduko idzi muoxygen sensor inobuda voltage senge shanduko mune yeokisheni yevasungwa mune yekuzadza gasi. Mhedzisiro inobuda kubva kumaoksijeni maseru yakadzikira kana yakawanda okisijeni iriko mune yekudzima (yakaonda nyika) uye yakakwira kana mashoma oxygen aripo mune iyo chiutsi (rich state).

Kana iyo PCM ikaona yakaderera magetsi kukosha mune yeoksijeni sensor reji yemagetsi, kodhi P2249 inochengetwa uye chisina kushanda chiratidzo mwenje (MIL) inogona kuvhenekera. Mota zhinji dzinoda akati wandei kupisa (pakutadza) kubatidza mwenje wekuyambira.

Chaiyo okisijeni sensor O2:

Chii chakakomba cheiyi DTC?

Izvo zvisina kukwana voltage pane iyo O2 sensor rejere redunhu inogona kukonzeresa kudzikira kwehupfumi hwemafuta uye kudzikiswa kweinjini kuita. P2249 inofanira kuiswa muboka seyakakomba uye inofanira kugadziriswa nekukurumidza sezvazvinogona.

Ndezvipi zvimwe zvezviratidzo zvekodhi?

Zviratidzo zveP2249 kodhi kodhi inogona kusanganisira:

• Yakaderedzwa mafuta anoshanda
• Yakaderedzwa injini simba
• Akachengeterwa Kugutsa Makodhi kana Akasendama / Akapfuma Exhaust Makodhi
• Service injini mwenje ichavheneka munguva pfupi

Ndezvipi zvimwe zvezvikonzero zvinowanzoitika zveiyo kodhi?

Zvikonzero zveiyi kodhi zvinogona kusanganisira:

• O2 sensor fiyuzi yakaputirwa
• Inokanganisa okisijeni sensor / s
• Yakatsva, yakapwanyika, yakaputswa, kana yakatemwa wiring uye / kana zvinongedzo

Ndeapi mamwe matanho ekutambudza iyo P2249?

Iwe unozoda yekuongorora scanner, digital volt / ohmmeter (DVOM) uye yakavimbika mota ruzivo sosi yekunyatsoongorora iyo P2249 kodhi.

Unogona kuchengetedza nguva nekutsvaga technical Service Bulletins (TSBs) iyo inoburitsa yakachengetwa kodhi, mota (gore, kugadzira, modhi, uye injini) uye zviratidzo zvakawanikwa. Idzi ruzivo runogona kuwanikwa mune yako mota ruzivo sosi. Kana iwe ukawana chaiyo TSB, inogona kukurumidza kugadzirisa dambudziko rako.

Mushure mekubatanidza iyo scanner kune mota yekuongorora chiteshi uye kutora ese akachengetwa makodhi uye inosanganisirwa kufomesa data furemu, nyora pasi ruzivo (kana kodhi ikazoonekwa kuti iri yepakati). Mushure meizvozvo, bvisa makodhi uye test drive mota kusvikira chimwe chezvinhu zviviri chikaitika; iyo kodhi inodzoreredzwa kana iyo PCM inopinda yakagadzirira modhi.

Iyo kodhi inogona kuve yakanyanya kuoma kuongorora kana iyo PCM ichipinda yakagadzirira modhi panguva ino nekuti kodhi iri yepakati. Mamiriro ezvinhu akatungamira mukutsungirira kweP2249 ingangoda kuwedzera kukuvara isati yagadziriswa. Kana iyo kodhi ikadzorerwa, ramba uchiongorora.

Iwe unogona kuwana chinongedzo chekuona, chinobatanidza pini, nzvimbo dzenzvimbo, madhirowa ewiring, uye ekuongorora ekuvhara mabhaidhigiramu (ane hukama nekodhi uye nemotokari iri kubvunzwa) uchishandisa chako ruzivo rwemota.

Tarisa tarisa iyo inosanganisirwa wiring uye zvinongedzo. Gadzirisa kana kutsiva wiring, yakatsva, kana yakakuvara wiring.

Shandisa iyo DVOM kutarisa voltage yeiyo O2 sensor pane yakakodzera pini yekubatanidza (padhuze neiyo sensor). Kana pasina voltage inowanikwa, tarisa iyo fuse fomati. Tsiva fema kana yakaremara fuses kana zvichidikanwa.

Kana magetsi akaonekwa, tarisa dunhu rakakodzera paPCM connector. Kana pasina magetsi akaonekwa, fungidzira dunhu rakashama pakati peiyo sensor iri mubvunzo nePCM. Kana magetsi akawanikwa imomo, fungidzira kukanganisa PCM kana PCM programming kukanganisa.

Kuti utarise maO2 sensors: Tanga injini uye ubvumire iyo kusvika kune yakajairika tembiricha yekushanda. Rega injini ishande (mune kwazvakarerekera kana kupaka). Iine scanner yakabatana nemotokari yekuongorora chiteshi, cherekedza iyo oxygen sensor yekuisa mune rwizi rwe data. Deredza pasi yako data rwizi kuti ubatanidze chete inokodzera data yekukurumidza mhinduro.

Kana maokisijeni okisi ari kushanda zvakajairika, iwo voltage pamhepo okisijeni maseru kumusoro kweiyo catalytic converter inotenderera ichienderera kubva 1 kusvika 900 millivolts apo PCM inopinda yakavharwa loop mode. Maseru-epamberi ekati anozo tenderera pakati pe1 kusvika 900 millivolts, asi iwo anozogadzikwa pane imwe nhanho uye osara akatsiga (achienzaniswa neye pre-kati sensors). Oxygen sensors ayo asiri kushanda nemazvo anofanirwa kutariswa seakashata kana injini iri mukushanda kwakanaka.

• Iyo yakaputika O2 sensor fuse haisi iyo inokonzeresa yakachengetwa P2249 kodhi, asi mhinduro kune pfupi dunhu mudunhu.
