P0044 Chiratidzo chepamusoro muoksijeni sensor heater (HO2S) redunhu redunhu (bhangi 1, sensor 3)
OBD-II DTC Dhata
HO2S Heater Kudzora Circuit Yakakwira (Bhengi 1 Sensor 3)
Izvi zvinorevei?
Iyi Yekuongorora Dambudziko Kodhi (DTC) ndeye yakajairika kodhi yekufambisa, zvinoreva kuti inoshanda kune OBD-II mota dzakashongedzwa, kusanganisira asi kwete kune Nissan, Mitsubishi, Mazda, Subaru, Toyota, VW, nezvimwe. zvakasiyana zvichienderana nechiratidzo / modhi.
Oxygen sensors ane chinhu chekudziya anoshandiswa zvakanyanya mumainjini emazuva ano. Heated oxygen sensors (HO2S) zvinhu zvinoshandiswa nePCM (Powertrain Control Module) kuona zviri mukati meokisijeni mu exhaust system.
Iyo PCM inoshandisa ruzivo kubva kuBhangi 1, HO3S # 2, kunyanya kuongorora kugona kweanoshandura chinogadzirisa. Chikamu chakakosha cheiyi sensor ndicho chinhu chinopisa. Ipo mumotokari pamberi peOBD II, iyo okisijeni sensor yaive imwechete-tambo sensor, izvozvi zvave kazhinji kazhinji ina-waya maseru: maviri akatsaurirwa kune iyo oksijeni sensor uye maviri akatsaurirwa kune inopisa chinhu. Iyo okisijeni sensor heater inonyanya kudzikisira iyo nguva inotora kusvika kune yakavharwa chiuno. Iyo PCM inoongorora iyo heater yekushandura-nguva. Iyo PCM zvakare inoramba ichitarisa iwo mahedhiyo mahedhi emagetsi asina kujairika kana, mune dzimwe nguva, kunyange asina kujairika azvino.
Iyo okisijeni sensor heater inodzorwa mune imwe yenzira mbiri, zvinoenderana nemotokari mhando. (1) Iyo PCM inodzora yakananga voltage kune heater, kungave yakanangana kana kuburikidza neokisijeni sensor (HO2S) relay, uye ivhu rinopihwa kubva mumotokari yakafanana nzvimbo. (2) Kune 12 volt bhatiri fiyuzi (B +) inopa 12 volts kuchinhu chekupisa chero nguva iko kuvesa kwabatidzwa, uye hita inodzorwa nemutyairi muPCM inodzora divi rakadzika redunhu remhepo. ... Kufungidzira kuti ndeupi wauinayo kwakakosha nekuti iyo PCM ichagadzirisa hita pasi pemamiriro akasiyana siyana.
Kana iyo PCM ikaona isina kujairika yakakwira voltage pamhepo heater wedunhu, P0044 inogona kuseta. Iyi kodhi inoshanda chete kune hafu yeiyo oxygen sensor yekupisa wedunhu.
zviratidzo
Zviratidzo zveP0044 kodhi kodhi inogona kusanganisira:
- MIL Kuvhenekera (Kukanganisa Chiratidzo Lamp)
Zvingangodaro, hakuzovi nezvimwe zviratidzo.
zvikonzero
Zvimwe zvinogona kukonzeresa P0044 kodhi zvinosanganisira:
- Inokanganisa inopisa okisijeni sensor # 3 pamutsara 1.
- Vhura muHeater Control Circuit (12V PCM Inodzorwa Maitiro)
- Ipfupi kune B + (bhatiri voltage) mune heater control wedunhu (12V PCM inodzorwa masystem)
- Vhura Ground Circuit (12V PCM Inodzorwa Maitiro)
- Ipfupi kusvika pasi muheater control wedunhu (pane PCM yakagadziriswa masisitimu)
Mhinduro dzinogoneka
Kutanga, tarisa ongororo yechitatu post-injini HO2S paBhangi 1 uye yayo wiring harness. Kana paine chero kukuvara kune iyo sensor kana chero kukuvara kune wiring, gadzirisa pazvinenge zvichidikanwa. Tarisa uone waya dzakafumurwa panopinda wiring. Izvi zvinowanzo kutungamira kuneta uye mapfupi maseketi. Ita shuwa kuti wiring inoendeswa kure nepombi yekuzadza. Gadzirisa iyo wiring kana kutsiva iyo sensor kana zvichidikanwa.
Kana zvakanaka, bvisa bhangi 3 # 1 HO2S uye uone kuti gumi nemaviri volts B + aripo neinjini yabviswa (kana pasi, zvinoenderana nesystem). Ongorora hita kudzora wedunhu (pasi) haina kugadzikana. Kana zvirizvo, bvisa iyo O12 sensor uye uiongorore kukuvara. Kana iwe uine mukana wekupokana hunhu, unogona kushandisa ohmmeter kuyedza kuramba kwechinhu chekupisa. Kusingaperi kushorwa kunoratidzira yakavhurika dunhu mune heater. Tsiva iyo oxygen sensor kana zvichidikanwa.
