Mene ne wannan yake nufi?

Wannan Lambar Matsalar Bincike (DTC) lambar watsawa ce gaba ɗaya, wanda ke nufin ya shafi duk motocin 1996 (Dodge, Ford, Chevy, Kia, Ram, Honda, Pontiac, da sauransu). Kodayake gabaɗaya, takamaiman matakan gyara na iya bambanta dangane da alama / ƙirar.

A cikin gogewa na, lokacin da motar OBD-II sanye take da lambar P2A01, yana nufin tsarin kula da wutar lantarki (PCM) ya gano rashin aiki a cikin ƙananan (ko bayan mai canzawa) firikwensin oxygen (O2) ko kewaye. Bankin 1 yana nuna ƙungiyar injin ɗin da ke ɗauke da lambar silinda ɗaya, kuma firikwensin 2 yana nuna cewa laifin yana tare da ƙaramin firikwensin.

Na'urorin firikwensin O2 sun ƙunshi wani abin firikwensin zirconia wanda ke da kariya ta gidan ƙarfe mai iska. Abun da ke ji yana haɗe da wayoyi a cikin O2 firikwensin wayoyi tare da wayoyin platinum. Cibiyar Kulawa (CAN) tana haɗa PCM zuwa kayan aikin firikwensin O2. Na'urar firikwensin O2 tana ba PCM da yawan adadin iskar oxygen a cikin injin injin idan aka kwatanta da iskar da ke cikin iskar yanayi.

Iskar gas mai fita tana fitar da injin daga cikin bututun mai shaye -shaye da kuma ta hanyar mai jujjuyawa; sannan ku wuce firikwensin O2 na ƙasa. Yayin da iskar gas ke wucewa ta hanyoyin iska a cikin gidan karfe da ta firikwensin, ana jawo iskar iska ta cikin ramin waya zuwa cikin ƙaramin ɗaki a tsakiyar firikwensin. A cikin ɗakin, iskar yanayi tana zafi ta hanyar shaye shaye, yana haifar da ions oxygen don samar da ƙarfin lantarki (makamashi). Canje -canje tsakanin adadin ƙwayoyin oxygen a cikin iska na yanayi (wanda aka jawo cikin firikwensin O2) da kuma yawan ions oxygen a cikin iskar gas yana haifar da canji a matakan ƙarfin lantarki.

Hankula oxygen haska O2:

Waɗannan canje -canjen suna haifar da ions oxygen a cikin firikwensin O2 don tashi da sauri kuma ba da daɗewa ba tsakanin yaduddukan platinum. Canje -canje na wutar lantarki yana faruwa lokacin da ions oxygen ke gudana tsakanin yadudduka na platinum. PCM tana gane waɗannan canje -canje na wutar lantarki kamar yadda canje -canje a cikin iskar oxygen a cikin iskar gas. Waɗannan canje -canjen suna nuna ko injin yana gudana a ɗora (ƙaramin mai) ko mai wadata (mai yawa). Alamar wutar lantarki daga firikwensin O2 tana ƙasa lokacin da ƙarin iskar oxygen ke cikin shaye -shaye (jingina) da mafi girma lokacin da ƙarancin iskar oxygen ke cikin shaye shaye (yanayin arziki). PCM na amfani da wannan bayanan don lissafin isar da mai da dabarun lokacin ƙonewa. Babban firikwensin O2 na sama yana amsawa tare da manyan sauye -sauye, yayin da firikwensin da ke ƙasa yakamata ya zama mafi kwanciyar hankali idan komai yana aiki yadda yakamata.
