OBD-II DTC Dhata

Tembiricha yemafuta yakanyanya kukwirira

Izvi zvinorevei?

Iyi Yekuongorora Dambudziko Kodhi (DTC) ndeye yakajairika kodhi yekufambisa, zvinoreva kuti inoshanda kune OBD-II mota dzakashongedzwa (Dodge, Ram, Ford, GMC, Chevrolet, VW, Toyota, nezvimwewo). Kunyangwe yakajairika, chaiwo matanho ekugadzirisa anogona kusiyana zvichienderana neiyo mhando / modhi.

Ndakaona kuti mota yeOBD II payakachengeta iyo P0168 kodhi, zvinoreva kuti iyo powertrain control module (PCM) yaona chiratidzo chevheteri kubva kune iyo tembiricha tembiricha sensor / mafuta ekuumba sensor kana dunhu rinoratidza kupisa kwakanyanya kwemafuta.

Iyo yekushisa tembiricha sensor inowanzo kuvakwa mukati memafuta ekugadzira sensor. Chinhu chidiki chemakomputa (chakafanana nefirita yemafuta) yakagadzirirwa kupa iyo PCM kuongororwa kwakaringana kwemafuta uye kupisa kwemafuta.

Fuel inopfuura neyakavakirwa-mukati sensor inoongororwa nemagetsi kuona yayo ethanol, mvura, uye isingazivikanwe (isiri-mafuta) zvinosvibisa. Iyo yekugadzira mafuta sensor haina kungoongorora maficha, asi zvakare inoyera tembiricha yemafuta uye inopa chiratidzo chemagetsi kuPCM iyo inoratidza kwete chete izvo zvinosvibisa zviripo (uye mwero wekushatiswa kwemafuta), asiwo tembiricha yemafuta. Iyo mwero wekushatiswa kwemafuta kunoongororwa neperesenti yezvinhu zvinosvibisa mumafuta; kuumbwa kwemagetsi siginecha mukuumbwa kwemafuta / sensor tembiricha.

Iyo siginecha yemagetsi inopinda muPCM seyemagetsi-emagetsi emagetsi masaini. Iwo mafomu ekushambadzira anosiyana muhuwandu zvichienderana nehuremu hwekusviba kwemafuta. Iyo padyo neiyo waveform frequency, inowedzerawo mwero wekushatiswa kwemafuta; ichi chinomiririra chikamu chakamira chechiratidzo. Iyo yekugadzira mafuta sensor inoongorora huwandu hweethanol iripo mumafuta zvakasiyana nehumwe hutachiona. Hupamhi hwekupomba kana chikamu chakatsetseka cheiyo waveform inoratidza iyo siginecha yemagetsi inogadzirwa nekupisa kwemafuta. Iyo yakanyanya kupisa tembiricha yemafuta inopfuura nepakati peturu tembiricha sensor; iyo inokurumidza iyo kupomba kwehupamhi. Chaizvoizvo kupomba kwepamhepo modulation inotenderera kubva kune imwe kusvika mashanu millisecond, kana zana rechipiri.

Kana iyo PCM ikaona yekuisa kubva kune mafuta tembiricha / yekuumbwa sensor inoratidza kuti huni tembiricha yakanyanya kukwirisa, P0168 kodhi inochengetwa uye chisina kushanda chiratidzo mwenje (MIL) inogona kuvhenekera. Pane mamwe mamodheru, akati wandei maficha (ane kusashanda zvakanaka) anogona kudikanwa kubatidza mwenje wekuyambira wemwenje wekuyambira.

Kodhi kuomarara uye zviratidzo

Podhi yakachengetwa P0168 kodhi inofanirwa kutorwa seyakaomarara nekuti tembiricha yemafuta inoshandiswa nePCM kuverenga nzira yekuendesa mafuta mumagetsi-mafuta emotokari.

Zviratidzo zvekodhi iyi zvinogona kusanganisira:

• Kazhinji, iyo P0168 kodhi haina chiratidzo.
• Mamwe makodhi ekugadzira mafuta anogona kunge aripo.
• Iyo MIL inozopedzisira yajekesa.

zvikonzero

Zvimwe zvikonzero zvekumisikidza kodhi iyi:

• Yakaremara mafuta kuumbwa / tembiricha sensor
• Yakashata ambient tembiricha sensor
• Yakawanda mweya tembiricha Switch chakaremara
• Vhura, ipfupi, kana yakakuvara wiring kana zvinongedzo
• PCM kana PCM purogiramu yekukanganisa

Kuongorora uye kugadzirisa maitiro

Nzvimbo yakanaka yekutanga nguva dzose yekutarisa technical Service Bulletins (TSB) kune yako chaiyo mota. Dambudziko rako rinogona kunge riri nyaya inozivikanwa neyakagadzirwa gadziriso-yakaburitswa gadziriso uye inogona kukusevha nguva nemari panguva yekugadzirisa matambudziko.

Kuti uongorore iyo P0168 kodhi, iwe unozoda yekuongorora scanner, digital volt / ohmmeter (DVOM), oscilloscope, infrared thermometer, uye mota ruzivo ruzivo (senge All Data DIY). Mune ino mamiriro, yekuongorora scanner ine yakavakirwa-muDVOM uye inotakurika oscilloscope ichauya inobatsira.

Kuti uwedzere mikana yako yekubudirira kuongororwa, tanga nekuona uchitarisa ese akabatanidzwa wiring matambo uye ma connector. Kana zvichidikanwa, iwe uchafanirwa kugadzirisa kana kutsiva zvakakanganiswa kana zvakapiswa zvinhu uye woedzazve iyo system.

Mazhinji emagetsi ekupisa maseru anopihwa neXNUMX B chirevo uye pasi. Seyenzanisiro yekudzivirira sensor, iyo yekushisa tembiricha sensor inovhara iyo dunhu uye inoburitsa yakakodzera waveform kune iyo PCM kana mafuta ari kuyerera. Uchishandisa iyo DVOM, tarisa iro rinotarisisa voltage uye pasi pane peturu tembiricha sensor chinobatanidza. Kana pasina gadziriro yemagetsi iripo, shandisa iyo DVOM kuyedza maseketi akakodzera paPCM chinongedzo. Kana chirevo chemagetsi chikawanikwa paPCM chinongedzo, gadzirisa maseketi akavhurika sezvazvinodiwa. Chenjedzo: Dzvanya vatyairi vese vane hukama usati waedza kuramba wedunhu neiyo DVOM.

Chengetedza PCM isina kukwana (kana purogiramu yekukanganisa) kana pasina magetsi ekutaura paPCM connector. Kana pasina peturu tembiricha yekunzwa pasi, shandisa yako mota ruzivo sosi uye uwane nzvimbo yakakodzera kuti uone kuti yakavimbika.

Shandisa oscilloscope kuona chaiyo-nguva data mumagrafu kana chiratidzo chefodhi uye pasi zviripo pane peturu tembiricha sensor chinobatanidza. Unganidzo bvunzo inotungamira kune akakodzera maseketi uye chengetedza iyo yekuratidzira skrini. Edzai chaiwo kupisa kwetembiricha ine infrared thermometer uye enzanisa mhedzisiro netembiricha inoratidzwa pamachati eoscilloscope. Kana tembiricha yemafuta inoratidzwa pa oscilloscope isingaenderane netembiricha ye infrared thermometer, fungidzira kuti iyo yekushisa tembiricha sensor haina kukwana.

Zvimwe zvekuongorora manotsi:

• Shandisa iyo DVOM kuyedza kuramba kweiyo tembiricha tembiricha sensor zvinoenderana nezvakakurudzirwa nemugadziri.
• Kana iyo chaiyo tembiricha yemafuta iri pamusoro pane inogamuchirwa, tarisa denderedzwa pfupi mune wiring kana zvisina kufanira kufambiswa gasi rekubvisa padyo netangi remafuta kana mitsara yekupa.
