P0044 Chizindikiro chachikulu mumayendedwe olamulira mpweya (HO2S) oyang'anira dera (banki 1, sensa 3)

Mapepala a OBD-II DTC

HO2S Heater Control Circuit High (Bank 1 SENSOR 3)

Kodi izi zikutanthauzanji?

Izi Diagnostic Trouble Code (DTC) ndi njira yotumizira, zomwe zikutanthauza kuti imagwira ntchito pamagalimoto okhala ndi OBD-II, kuphatikiza Nissan, Mitsubishi, Mazda, Subaru, Toyota, VW, ndi zina zambiri. zimasiyana kutengera mtundu / mtundu.

Masensa a oxygen okhala ndi chinthu chotenthetsera amagwiritsidwa ntchito kwambiri mu injini zamakono. Makanema otenthetsera okosijeni (HO2S) ndi zolowetsa zomwe zimagwiritsidwa ntchito ndi PCM (Powertrain Control Module) kuti azindikire kuchuluka kwa okosijeni muutsi.

PCM imagwiritsa ntchito zidziwitso kuchokera ku Bank 1, HO3S # 2, makamaka kuti iwunikire momwe othandizira kusintha alili. Gawo lofunikira la sensa iyi ndi chinthu chotenthetsera. Pomwe mgalimoto isanachitike OBD II, kachipangizo ka oxygen kanali kachipangizo kamodzi, ndipo nthawi zambiri amakhala ndi zida zamagetsi zinayi: ziwiri zoperekedwa kwa sensa ya oxygen ndipo ziwiri zoperekedwa kutenthetsera. Chotenthetsera cha oxygen chimachepetsa nthawi yomwe chimatenga kuti chifike potseka. PCM imayang'anira nthawi yoyatsa chowotcha. PCM imawunikiranso mosalekeza ma circuator amagetsi osazolowereka kapena, nthawi zina, ngakhale pakali pano.

Chotenthetsera cha oxygen chimayendetsedwa m'njira imodzi mwanjira ziwiri, kutengera mtundu wamagalimoto. (1) PCM imayendetsa mwachindunji magetsi pamagetsi, kapena molunjika kapena kudzera pa kachipangizo ka oxygen (HO2S), ndipo nthaka imaperekedwa kuchokera pamalo omwe onse amagwirizana. (2) Pali fyuzi yamagetsi ya 12 volt (B +) yomwe imapereka ma volts 12 pazinthu zotenthetsera nthawi iliyonse kuyatsa kumayatsidwa, ndipo chowotcha chimayang'aniridwa ndi driver wa PCM yemwe amayang'anira mbali yazungulira ya heater heater. ... Kuzindikira chomwe muli nacho ndikofunikira chifukwa PCM idzatsegula chotenthetsera m'malo osiyanasiyana.

PCM ikazindikira kuti pamagetsi akutentha kwambiri, P0044 imatha kukhazikika. Code iyi imangogwira theka la dera lotenthetsera sensa ya oxygen.

Zizindikiro

Zizindikiro za vuto la P0044 zitha kuphatikiza:

• Kuunikira kwa MIL (Nyali Yazizindikiro Zosagwira)

Ambiri mwina, sipadzakhalanso zizindikiro zina.

zifukwa

Zomwe zingayambitse kachidindo ka P0044 ndi izi:

• Chotupa chotentha cha oxygen # 3 pamzere 1.
• Tsegulani mu Heater Control Circuit (12V PCM Controlled Systems)
• Pafupifupi B + (batri yamagetsi) mu makina oyendetsa chotenthetsera (makina a 12V PCM owongoleredwa)
• Open Ground Circuit (Makina Oyendetsedwa ndi 12V PCM)
• Pafupipafupi panthaka yoyendetsa chotenthetsera (pamakina a PCM okhazikika)

Mayankho otheka

Choyamba, yang'anani mozama HO2S yachitatu yotsatira injini ku Bank 1 ndi zingwe zake. Ngati pangakhale kuwonongeka kwa sensa kapena kuwonongeka kwa waya, konzani ngati pakufunika kutero. Fufuzani mawaya owonekera pomwe mawilo amalowa mu sensa. Izi nthawi zambiri zimabweretsa kutopa komanso madera amfupi. Onetsetsani kuti zingwe zachotsedwa kutali ndi chitoliro cha utsi. Konzani zingwe kapena m'malo mwa sensa ngati kuli kofunikira.

Ngati zili bwino, sankhani Bank 3 # 1 HO2S ndikuwonetsetsa kuti ma Volts B + 12 alipo injini ikachotsedwa (kapena pansi, kutengera dongosolo). Fufuzani kuwonongeka kwa dera loyendetsa chotenthetsera (nthaka). Ngati ndi choncho, chotsani kachipangizo cha O2 ndikuyang'anitsitsa kuti chiwonongeke. Ngati muli ndi zida zotsutsana, mutha kugwiritsa ntchito ohmmeter kuyesa kuyesa kwa chinthu chotenthetsera. Kupanda malire kumawonetsa dera lotseguka chotenthetsera. Sinthani kachipangizo ka oxygen ngati kuli kofunikira.

Zokambirana zokhudzana ndi DTC

• Pakadali pano palibe mitu yofananira m'mabwalo athu. Tumizani mutu watsopano pamsonkhano tsopano.

Mukufuna thandizo lina ndi nambala yanu ya p0044?

Ngati mukufunabe thandizo ndi DTC P0044, lembani funso mu ndemanga pansipa pamutuwu.

ZINDIKIRANI. Izi zimaperekedwa kuti zidziwitse zokha. Sikuti tizigwiritsa ntchito ngati malingaliro okonzanso ndipo sitili ndi udindo pazomwe mungachite pagalimoto iliyonse. Zomwe zili patsamba lino ndizotetezedwa ndi zovomerezeka.
