P0074 Ambient Yemhepo Kupisa Sensor Circuit Intermittent
OBD-II DTC Dhata
Ambient Mhepo Yekutonhora Sensor Dunhu Kukanganisa
Izvi zvinorevei?
Iyi generic transmission / engine DTC inowanzo shanda kune ese OBDII mota dzakashongedzwa.
Iyo inodziya yemhepo tembiricha (AAT) sensor inoshandura tembiricha iri mukati mechiratidzo chemagetsi kune powertrain control module (PCM). Iyi yekuisa inoshandiswa kushandura mashandiro eiyo mamiriro emhepo uye kuratidza iyo yekunze tembiricha.
PCM inowana iyi yekuisa uye pamwe mamwe maviri; Inotora mweya tembiricha (IAT) uye injini inotonhorera tembiricha (ECT) sensor. Iyo PCM inotarisa iyo AAT sensor voltage uye ichifananidza iyo neIAT / ECT sensor kuverenga kana iko kupisa kwatanga kuvhurwa mushure menguva refu inotonhorera-pasi. Iyi kodhi inoiswa kana izvi zvinongedzo zvasiyana zvakanyanya. Inotarisawo magetsi emagetsi kubva kuma sensors aya kuti aone kana ari iwo chaiwo kana injini yanyatsodziya. Iyi kodhi inowanzoiswa nekuda kwematambudziko emagetsi.
Matanho ekugadzirisa matambudziko anogona kusiyana zvichienderana nemugadziri, mhando yeAAT sensor, uye waya waya.
zviratidzo
Zviratidzo zvinogona kusanganisira:
- Chiedza chiratidzo chemwenje chiripo
- Iyo yekugadzirisa mhepo inogona kusashanda nemazvo
- Sumbu remidziyo rinogona kusakwanisa kuverenga tembiricha yekunze nemazvo
- Pamusoro koni inogona kusakwanisa kuverenga tembiricha iri mukati nemazvo
zvikonzero
Zvimwe zvinogona kukonzera DTC P0074 zvinogona kusanganisira:
- Inopindirana yakavhurika muchiratidzo chedunhu kune AAT sensor - ingangoita
- Inopindirana ipfupi kune magetsi mudunhu rechiratidzo reAAT sensor
- Inopindirana ipfupi kusvika pasi mukutenderera kwedunhu kune AAT sensor
- Inokanganisa AAT sensor
- Yakakundikana PCM - Hazvigoneki
Mhinduro dzinogoneka
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.
Wobva watsvaga iyo AAT sensor pane yako chaiyo mota. Iyi sensor inowanzo kuve pamberi peiyo radiator kuseri kweiyo grille kana munzvimbo yepamberi bhamba. Kana uchinge waonekwa, zviongorore ongorora zvinobatanidza uye wiring. Tarisa mitsetse, scuffs, waya dzakafumurwa, kupisa maki, kana plastiki yakanyungudika. Bvisa ma connector uye nyatsoongorora zviteshi (simbi zvikamu) mukati mezvinobatanidza. Tarisa uone kana vachitaridzika kunge akatsva kana vane tint yegirini inoratidza kuora. Kana iwe uchida kuchenesa zviteshi, shandisa yemagetsi yekubata yakachena uye epurasitiki bristle bhurasho. Rega kuomesa nekuzora mafuta emagetsi panobatwa zviteshi.
Mhosva yakajairika ndeyekubatanidza, ine inokanganisa sensor inouya munzvimbo yechipiri nekuda kwemamiriro ekunze akaipa.
Paunenge uchitarisa kubatana, unogona kutarisa iyo sensor uchishandisa digital volt ohm mita (DVOM). Kubatidza OFF, bvisa iyo sensor uye batanidza iyo tsvuku (yakanaka) DVOM terminal kune imwe terminal pane iyo sensor uye iyo nhema (isina) DVOM terminal kune imwe terminal. Sarudza iyo tembiricha yeiyo sensor (chii chiri tembiricha kunze) nekumira zvinoenderana netafura. Uku ndiko kuramba kwe ohm kunofanirwa kuratidzwa neDVOM yako. Chero 0 ohms kana risingapikisi kuramba (kazhinji kunoratidzwa nemavara OL) inoratidza yakashata sensor.
Kana iwe uine scan chishandiso, bvisa iyo yekunetseka matambudziko macode kubva mundangariro uye ona kana iyo kodhi inodzoka. Kana iyi isiri iyo kesi, saka panogona kunge paine chinetso chekubatanidza.
Kana iyo P0070 kodhi ikadzoka, isu tichafanirwa kuyedza iyo AAT sensor uye akabatana macircuit. Kazhinji pane 2 waya paAAT sensor. Galvanzii OFF, patsanura harani panguva AAT Switch. Chinja pane kuvesa. Iine scan chishandiso chinowana iyo PCM dhata (uchifungidzira kuti iri module inogamuchira AAT sensor yekuisa; iyo module inogamuchira AAT sensor yekuisa inogona kunge iri mhepo yekugadzirisa mamiriro module, yepasirese yemagetsi module, kana imwe module kune yakanangana nemotokari iyo inogona kutumira AAT sensor data pamusoro penzvimbo yebhazi), verenga tembiricha kana voltage yeAAT sensor. Inofanira kuratidza mashanu volts kana chimwe chinhu kunze kwekunze kwekushisa tembiricha (yakadzika kwazvo tembiricha) mumadhigri. Tevere, bvisa kuvesa, batanidza iyo jumper waya kune maviri ma terminals mukati meiyo harness connector kuenda kune AAT sensor, wobva wadzima kubatidza. Inofanira kuverenga nezve 5 volts kana chimwe chinhu kunze kwekunze kwekushisa (yakanyanya kupisa) mumadhigirii. Kana pasina 0 volt pane iyo sensor kana iwe ukaona pasina shanduko, gadzirisa iyo wiring kubva kuPMM kuenda kune iyo sensor, kana kuti ingangoita yakaipa PCM.
Dzorera zvakare sensor uye fambisa chinongedzo uchiongorora magetsi kana madhigirii kubva kuAAT sensor. Kana, iwe uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchiita. Tarisa uone panotenderedzwa waya uye mucherechedze chero pavangabata / kukwiza kuzorwa nepaneru yemuviri kana furemu.
Kana bvunzo dzese dzakapfuura dzikapfuurira uye iwe uchiramba uchigamuchira P0070, izvi zvingangodaro zvichiratidza chakakundikana AAT sensor, kunyangwe iyo yakakundikana control module isingakwanise kutongwa kunze kusvikira iyo AAT sensor yatsiviwa. Kana iwe usina chokwadi, tsvaga rubatsiro kubva kune anokwanisa mota diagnostician. Kuisa nenzira kwayo, PCM inofanirwa kuve yakagadzirirwa kana kuyerwa pamotokari.
