Izvi zvinorevei?

Iyi generic Diagnostic Dambudziko Kodhi (DTC) inoshanda kune mazhinji OBD-II mota (1996 uye nyowani). Izvi zvinogona kusanganisira, asi hazvirevi kune, Mazda, VW, Acura, Kia, Toyota, BMW, Peugeot, Lexus, Audi, nezvimwe. Kunyangwe hazvo zvakasarudzika, matanho chaiwo ekugadzirisa anogona kusiyana zvichienderana negore rekugadzira, brand, mhando uye kufambiswa.

Kodhi yakachengetwa P2256 inoreva kuti powertrain control module (PCM) yaona kusawirirana kwazvino mumhepo yepamusoro yeokisijeni (O2) sensor yeinjini yebhangi nhamba yechipiri. Bank two iboka reinjini dzisina nhamba imwe humburumbira. Sensor 1 ndiyo yepamusoro (pre) sensor. Iyo yakaipa ikozvino yekudzora dunhu idunhu repasi.

Iyo PCM inoshandisa zvinongedzo kubva kunopisa okisijeni maseru (HO2S) kuongorora iyo okisijeni zvirimo mumweya wekubvisa webhangi reinjini imwe neimwe, pamwe nekugona kwemuchinjisi wekuchinja.

Iwo maserujeni eoksijeni anovakwa achishandisa zirconia yekuona chinhu chiri pakati penzvimbo yesimbi dzimba. Diki platinikodhi yemagetsi inosungirirwa pakati pechinhu chekunzwa uye mawaya ari muoksijeni sensor sunga chinobatanidza. Iyo O2 sensor harness connector inosangana kune controller network (CAN), iyo inobatanidza iyo oxygen sensor harness kune PCM yekubatanidza.

Imwe HO2S ine tambo (kana zvihwitsi) mupombi yekuzadza kana yakawanda. Yakamira kuitira kuti chinhu chekunzwa chiri padyo nepakati pombi. Gasi rekutsvaira gasi rinosiya kamuri rinotsva (kuburikidza neakawanda maneti) uye pfuura nepasefu system (inosanganisira vanoshandura vanogadzirisa); idonhedza pamusoro peokisijeni sensors. Gasi rekudzimisa rinopinda mukati memhepo yeoksijeni kuburikidza neakagadzirirwa mweya magemenzi mudzimba dzesimbi uye anotenderera akatenderedza sensor element. Mhepo yakavhomorwa nepakati pematare mukati meimba yekunzwa inozadza kamuri diki iri pakati peiyo sensor. Mhepo inopisa (mukamuri diki) inokonzeresa ioni yeoksijeni kuburitsa simba, iro rinozivikanwa nePCM semagetsi.

Misiyano pakati peiyo huwandu hweO2 ions mumhepo yakatenderedza uye huwandu hwemakemikari mamorekuru mune yekuzadza anokonzera kupisa okisijeni ions mukati me HO2S kubhururuka nekukurumidza uye zvakapatsanuka kubva kune imwe platinamu rukanda kuenda kune inotevera. Sezvo ioni yeoksijeni inodhonha ichifamba pakati pezvikamu zveplatinamu, iyo HO2S inobuda magetsi magetsi. Iyo PCM inoona shanduko idzi mu HO2S inobuda voltage senge shanduko mune yeokisheni yevasungwa mune yekuzadza gasi.

Mhepo inobuda kubva ku HO2S yakadzikira kana yakawanda okisijeni iriko mukuwasha (yakatetepa nyika) uye yakakwira kana okisijeni shoma irimo mukuwandisa (hupfumi nyika). Ichi chikamu che HO2S chinoshandisa yakaderera voltage (isingasviki imwe volt).

Muchikamu chakaparadzaniswa cheiyo sensor, iyo HO2S inotungidzirwa kupisa bhatiri voltage (12 volts). Kana tembiricha yeinjini yakadzikira, bhatiri voltage inopisa iyo HO2S saka inogona kutanga kuongorora okisijeni mune iyo chiutsi nekukurumidza.

Kana iyo PCM ikaona yakanyanya kukwirira voltage uye isiri mukati memiganhu inogamuchirwa, P2256 inochengetwa uye Malfunction Indicator Lamp (MIL) inogona kuvhenekera. Mota zhinji dzinoda akati wandei kupisa (pakutadza) kubatidza mwenje wekuyambira.

Chaiyo okisijeni sensor O2:

Chii chakakomba cheiyi DTC?

HO2S ine dunhu rekudzora kusashanda inogona kukonzeresa kushomeka kweinjini kuita uye akasiyana matambudziko ekubata. Iyo P2256 kodhi inofanirwa kuverengerwa seyakakomba uye nekugadziriswa nekukurumidza sezvazvinogona.

Ndezvipi zvimwe zvezviratidzo zvekodhi?

Zviratidzo zveP2256 kodhi kodhi inogona kusanganisira:

• Yakadzikira mafuta kunyatsoshanda
• Yakaderedzwa injini kuita
• 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:

• Inokanganisa okisijeni sensor / s
• Yakatsva, yakapwanyika, yakaputswa, kana yakatemwa wiring uye / kana zvinongedzo
• Yakakanganisa PCM kana PCM yekukanganisa kukanganisa

Ndeapi mamwe matanho ekutambudza iyo P2256?

Yechokwadi kuongororwa kweP2256 kodhi kunoda yekuongorora scanner, digital volt / ohmmeter (DVOM), uye yakavimbika mota ruzivo sosi.

Unganidza iyo scanner kune mota yekuongorora chiteshi uye tora ese akachengetwa makodhi uye anoenderana nechando fomu data. Iwe uchazoda kunyora ruzivo urwu pasi kuitira kuti kodhi yacho ikazove yepakati. Wobva wabvisa makodhi uye bvunzo kutyaira mota. Panguva ino, chimwe chezvinhu zviviri chichaitika. Chero P2256 ichajekeswa kana iyo PCM inopinda yakagadzirira modhi.

Kana iyo kodhi iri yepakati uye iyo PCM inopinda yakagadzirira modhi, zvingave zvakanyanya kunetsa kuongorora. Mamiriro ezvinhu akatungamira mukuchengetwa kweP2256 angangoda kuwedzera kusati kwanyatsozivikanwa kuongororwa. Kana iyo kodhi yakabviswa, ramba uchiongorora.

Connector faceplates, connector pinout diagrams, zvikamu zvezvirongwa, wiring diagrams, uye diagnostic block diagrams (yakabatana nekodhi yakabatana nemotokari) inogona kuwanikwa uchishandisa yako motokari ruzivo.

Tarisa tarisa HO2S inoenderana wiring uye zvinongedzo. Tsiva wiring yakachekwa, yakatsva, kana yakakuvara.

Dzinga ma HO2S ari mubvunzo uye shandisa iyo DVOM kuyedza kuramba pakati peasina kunaka magetsi ekudzora wedunhu uye chero magetsi emagetsi. Kana paine kuenderera, fungidzira yakakanganisa HO2S.

Kana iyo P2256 kodhi ikaramba ichigadzirisa, tanga injini. Bvumidza iyo kudziya kusvika kune yakajairwa tembiricha yekushanda uye isina basa (iine hutachiona mune kwazvakarerekera kana paki). Batanidza iyo scanner kune mota yekuongorora chiteshi uye chengetedza okisijeni sensor yekuisa mune rwizi rwe data. Deredza pasi yako data rwizi kuti ubatanidze chete data rakakodzera rekupindura nekukurumidza.

Kana maokisijeni okisi ari kushanda zvakajairika, iyo voltage pamhepo okisijeni maseru kumusoro kweiyo catalytic converter inotenderera ichienderera kubva 1 kusvika 900 millivolts apo PCM inopinda yakavharwa loop mode. Post-Cat sensors zvakare inotenderera pakati pe1 kusvika 900 millivolts, asi ivo vanozoiswa pane yakatarwa poindi voramba vakagadzikana (zvichienzaniswa neye pre-kati sensors). HO2S isiri kushanda nemazvo inofanirwa kutarisirwa seyakaremara kana injini iri kushanda zvakanaka.

Kana iyo HO2S iri kuratidza bhatiri voltage kana isina magetsi muiyo scanner dhata, shandisa iyo DVOM kuwana chaiyo-nguva data kubva ku HO2S chinongedzo. Kana zvabuda zvikaramba zvakafanana, fungidzira kuti yemukati HO2S ipfupi iyo inoda kutsiviwa kwe HO2S.

• Muzviitiko zvakawanda, iwe unogadzirisa iyi kodhi yekodhi nekutsiva HO2S yakakodzera, asi zadzisa kuongororwa zvakadaro.
