Bayanan Bayani na OBD-II

Ƙarancin siginar siginar a cikin siginar firikwensin zazzabi mai ƙarfi (banki 2, firikwensin 2)

Mene ne wannan yake nufi?

Wannan Lambar Matsalar Bincike (DTC) lambar watsawa ce gabaɗaya, wanda ke nufin ya shafi motocin OBD-II sanye take da firikwensin zafin jiki (Subaru, Ford, Chevy, Jeep, Nissan, Mercedes-Benz, Toyota, Dodge, da sauransu) D.)). Duk da yanayin gabaɗaya, ainihin matakan gyara na iya bambanta dangane da yin / ƙirar.

Na'ura mai canzawa tana ɗaya daga cikin mahimman sassa na kayan shaye-shaye akan mota. Gas masu fitar da iskar gas suna ratsawa ta hanyar mai canzawa inda wani sinadarin ke faruwa. Wannan halayen yana canza carbon monoxide (CO), hydrocarbons (HO) da nitrogen oxides (NOx) zuwa ruwa mara lahani (H2O) da carbon dioxide (CO2).

Ana kula da ingancin mai canzawa ta na'urori masu auna iskar oxygen guda biyu; ana shigar da daya a gaban mai canzawa, ɗayan kuma bayansa. Ta hanyar kwatanta siginar firikwensin iskar oxygen (O2), tsarin sarrafa wutar lantarki (PCM) na iya tantance ko mai canza kuzari yana aiki da kyau. Madaidaicin firikwensin zirconia pre-catalyst O2 yana saurin sauya fitowar sa tsakanin kusan 0.1 da 0.9 volts. Karatun 0.1 volts yana nuna ƙarancin iska / cakuda mai, yayin da 0.9 volts yana nuna cakuda mai wadatarwa. Idan mai jujjuya yana aiki da kyau, firikwensin ƙasa yakamata ya kasance barga a kusan 0.45 volts.

Ingancin mai jujjuyawa da zafin jiki suna da alaƙa. Idan mai juyawa yana aiki yadda yakamata, zafin fitarwa yakamata ya ɗan fi girma fiye da zafin zafin shiga. Tsohuwar dokar babban yatsa ita ce Fahrenheit 100. Koyaya, yawancin motocin zamani na iya nuna wannan banbanci.

Babu ainihin "firikwensin zazzabi mai haɓakawa". Lambobin da aka bayyana a cikin wannan labarin suna don firikwensin oxygen. Bankin 2 na lambar yana nuna cewa matsalar tana tare da injin injin na biyu. Wato, bankin da bai ƙunshi silinda # 1 ba. “Sensor 2” yana nufin firikwensin da aka sanya a ƙarƙashin mai jujjuyawar mahaɗan.

DTC P043C yana saita lokacin da PCM ta gano siginar firikwensin yanayin zafi mai ƙarfi a cikin banki 2, mai haɗa firikwensin zafin jiki 2. Wannan yawanci yana nuna gajeru a cikin da'irar.

Hanyoyin bincike da gyara

Fara ta hanyar duba na'urar firikwensin iskar oxygen da ke ƙasa da wayoyi masu alaƙa. Nemo hanyoyin haɗin kai, wayoyi da suka lalace, da dai sauransu. Haka nan kuma bincika ɓoyayyen ɓoyayyen gani da gani. Ruwan shaye -shaye na iya haifar da lambar firikwensin iskar oxygen. Idan an sami lalacewa, gyara yadda ake buƙata, share lambar kuma duba idan ta dawo.

Sannan duba bayanan sabis na fasaha (TSBs) don matsalar. Idan ba a sami komai ba, kuna buƙatar ci gaba zuwa binciken tsarin mataki-mataki. Na gaba shine hanya gaba ɗaya kamar yadda gwajin wannan lambar ya bambanta daga abin hawa zuwa abin hawa. Don gwada tsarin daidai, kuna buƙatar komawa zuwa tsarin bincike don takamaiman abin hawa / ƙirar abin hawa.

Duba sauran DTCs

Ana iya saita lambobin firikwensin oxygen sau da yawa saboda lamuran aikin injiniya wanda ke haifar da rashin daidaituwa a cikin cakuda iska / mai. Idan akwai wasu DTC da aka adana, za ku so ku share su da farko kafin ku ci gaba da binciken firikwensin oxygen.

Duba aikin firikwensin

Ana yin wannan mafi kyau tare da kayan aikin dubawa ko, mafi kyau duk da haka, oscilloscope. Tun da yawancin mutane ba su da damar yin fa'ida, za mu duba bincikar na'urar firikwensin oxygen tare da kayan aikin bincike. Haɗa kayan aikin dubawa zuwa tashar ODB ƙarƙashin dashboard. Kunna kayan aikin dubawa kuma zaɓi Bankin 2 Sensor 2 Voltage parameter daga jerin bayanan. Kawo injin ɗin zuwa yanayin zafin aiki kuma duba aikin kayan aikin scan ɗin a hoto.

Na'urar firikwensin yakamata ta sami tsayayyen karatu na 0.45 V tare da canjin yanayi kaɗan. Idan bai amsa daidai ba, tabbas yana buƙatar maye gurbinsa.

Duba kewaye

Na'urorin firikwensin iskar oxygen suna samar da siginar ƙarfin lantarki wanda aka mayar da su zuwa PCM. Kafin ci gaba, kuna buƙatar tuntuɓar zane -zanen kayan aikin masana'anta don tantance wace wace ce. Autozone yana ba da jagororin gyara kan layi kyauta don motoci da yawa, kuma ALLDATADIY yana ba da biyan kuɗin mota ɗaya. Don gwada ci gaba tsakanin firikwensin da PCM, kunna maɓallin ƙonewa zuwa wurin kashewa kuma cire haɗin mai haɗa firikwensin O2. Haɗa DMM zuwa juriya (kashe wuta) tsakanin tashar siginar firikwensin O2 akan PCM da waya sigina. Idan karatun mita bai wuce haƙuri ba (OL), akwai kewaye kewaye tsakanin PCM da firikwensin da ke buƙatar kasancewa da gyara. Idan lissafin yana karanta ƙimar lambobi, akwai ci gaba.

Sa'an nan kuma kana buƙatar duba ƙasa na kewaye. Don yin wannan, kunna maɓallin kunnawa zuwa kashewa kuma cire haɗin mai haɗa firikwensin O2. Haɗa DMM don auna juriya (kashe wuta) tsakanin tashar ƙasa na mai haɗa firikwensin O2 (gefen kayan doki) da ƙasa. Idan karatun mita bai fita daga haƙuri ba (OL), akwai buɗaɗɗen da'irar a gefen ƙasa wanda dole ne a nemo shi kuma a gyara. Idan mitar ta nuna ƙimar lamba, akwai fashewar ƙasa.

Kuna buƙatar ƙarin taimako tare da lambar p043C?

Idan har yanzu kuna buƙatar taimako tare da DTC P043C, aika tambaya a cikin sharhin da ke ƙasa wannan labarin.
