P0172 - Diagnostic kodhi yakawandisa musanganiswa

29.08.2022 /

Tsanangudzo yehunyanzvi yeOBD2 dambudziko kodhi - P0172

Kukanganisa p0172 zvinoreva kuti musanganiswa wakanyanya kupfuma (kana system yakapfuma zvakanyanya). saka, musanganiswa wemafuta wakagadziridzwa zvakare unopihwa kune macylinders anopisa. Senge kodhi P0171, yakapfuma musanganiswa kukanganisa kukanganisa system. Ndiko kuti, hazviratidzi kuparara kwakajeka kwema sensors, asi zviyero zvehuwandu hwemafuta zvinodarika kukosha kwemuganhu.

Zvichienderana nechikonzero chakakonzera kutaridzika kwekodhi yakadaro yekukanganisa, maitiro emotokari zvakare akasiyana. Mune zvimwe zviitiko, pachava nekuonekwa kwemafuta ekushandisa, uye mune zvimwe, kungodzipwa pasina basa kana kushambira kumhanya, kungave pane inopisa mukati meinjini yekupisa, kana kana kuchitonhora zvakare.

Mamiriro ekusaina kukanganisa

Iyo injini yekupisa yemukati inofanirwa kutangwa uye kupihwa kwemafuta kunoitika nemhinduro kubva kune okisijeni sensor (lambda probe), nepo pasina kukanganisa kubva kune inotonhorera sensor, yekupinda tembiricha yemhepo sensor, absolute pressure (MAP - sensor), DPRV, DPKV uye. throttle position sensor. Kana avhareji yehuwandu hwemafuta enguva pfupi uye kwenguva refu ari pasi pe33% kweanopfuura maminetsi matatu kubva panguva 3 yekuyedza. Iyo mwenje wechiratidzo pane dhizaini inongobuda chete kana iyo diagnostic ikasaona kusashanda mushure mematatu ekuyedza.

Zviratidzo zveP0172 kodhi zvinogona kusanganisira:

  • Kakawanda moto.
  • Kunwisa mafuta
  • Chiedza cheinjini chakabatidzwa.
  • Izvi chete zviratidzo zvakajairika zvinogona kuitika mune mamwe makodhi.

Zvinogoneka zvikonzero zvekukanganisa p0172

Diagnostic Dambudziko Code (DTC) P0172 OBD II.

kuti unzwisise kuti chii chakakonzera kukanganisa kwakapfuma musanganiswa, iwe unofanirwa kuita runyoro rwezvikonzero zvako uchishandisa diki algorithm.

Kupfumisa kwemusanganiswa kunoonekwa nekuda kwekupisa kusingakwane (kuwedzeredza kupihwa kana kushomeka kwemhepo):

  • kana mafuta asingatsva, ipapo makenduru kana makoiri haashande zvakanaka;
  • kana ichipihwa zvakawandisa, iyo okisijeni sensor kana majekiseni ane mhosva;
  • mweya usina kukwana - iyo inoyerera yemhepo sensor inopa data isiriyo.

Mafuta akawandisa kashoma kuitika, asi kushaya mweya idambudziko chairo. Mhepo inopihwa kumafuta inoitika pahukama pakati pe MAP sensor uye lambda probe. Asi kunze kwemasensa, dambudziko rinogonawo kukonzerwa nekutyorwa kwekupisa kwemagetsi (injini dzine HBO), kukuvadzwa kwemagetsi kune akasiyana gaskets uye zvisimbiso, kusashanda panguva, kana kusakwana kumanikidza.

kuitira kubata nezvose zvinobvira masosi zvakakonzera kukundikana, cheki inoitwa zvinoenderana neanotevera mapoinzi:

  1. Ongorora ruzivo kubva ku scanner;
  2. Tevedzera mamiriro ekuitika kwekukundikana uku;
  3. Tarisa zvikamu uye masisitimu (kuvapo kwevanoshamwaridzana vakanaka, kushayikwa kwekudhonza, kushanda), izvo zvinogona kutungamira pakuonekwa kwekukanganisa p0172.

Main checkpoints

Kubva pane zviri pamusoro, tinogona kuona zvikonzero zvikuru:

  1. DMRV (kuyerera kwemhepo mita), kusvibiswa kwayo, kukuvara, kurasikirwa kwekusangana.
  2. Sefa yemhepo, yakavharwa kana kubuda kwemhepo.
  3. Oxygen sensor, kushanda kwayo kusina kunaka (kuora, kukuvadza wiring).
  4. Iyo adsorber valve, iyo isiriyo kushanda kwayo inokanganisa kuteya kwepeturu mhute.
  5. Fuel njanji pressure. Kuwedzeredza, kunogona kukonzerwa nekukanganisa kudzvanya regulator, yakakuvadzwa mafuta ekudzosa system.

Troubleshooting P0172 musanganiswa wakanyanya kupfuma

Naizvozvo, kuti uwane iyo ine mhosva node kana system, iwe uchafanirwa kutarisa iyo MAF, DTOZH uye lambda probe sensors ine multimeter. Wobva watarisa ma spark plugs, waya nemakoiri. Eresa kudzvanywa kwemafuta nedhisheni yemagetsi. Tarisa mavanga ekubatidza. Tarisa zvakare panopinda mhepo uye pedza manifold ekubatanidza kune mhepo inobuda.

Mushure mekugadzirisa dambudziko, iwe unozofanirwa kuseta zvakare chidimbu chemafuta kuitira kuti udzore iyo yenguva refu yekucheka kusvika ku0%.

Mushure mekutevera kurudziro yese, iwe zvechokwadi uchakwanisa kutarisana nekushanda kwakashata kweinjini yekupisa kwemukati uye kuiswa kwekodhi yekukanganisa P0172 zvese paVAZ uye pamotokari dzekunze seToyota kana Mercedes, pamwe nedzimwe mota dzine magetsi. controls. Kunyangwe kazhinji zvisingakodzeri kupedzisa mapoinzi ese, kazhinji nekutsvaira kana kutsiva iyo DMRV kana iyo okisijeni sensor.
