P2069 Sensor B Matsayin Mai Fassarar B

Bayanan Bayani na OBD-II

Rashin aiki na sarkar ma'aunin matakin mai "B"

Mene ne wannan yake nufi?

Wannan Generic Transmission / Engine DTC galibi ya shafi duk injunan da ke sanye da OBDII, amma ya fi yawa a wasu motocin Hyundai, Infiniti, Isuzu, Kia, Mazda, Mercedes Benz, Nissan da Subaru.

Ana shigar da firikwensin matakin mai (FLS) a cikin tankin mai, yawanci a saman tankin mai / famfon mai. FLS tana canza matakin mai na inji zuwa siginar lantarki zuwa tsarin sarrafa wutar lantarki (PCM). Yawanci, PCM zai sanar da sauran masu sarrafawa ta amfani da bas ɗin bayanan abin hawa.

PCM yana karɓar wannan siginar ƙarfin lantarki don tantance yawan man da yake da shi a cikin tankin mai, yana sa ido kan amfani da mai sannan kuma yana tantance tattalin arzikin mai. An saita wannan lambar idan wannan shigarwar ba ta dace da madaidaicin ƙarfin aiki da aka adana a cikin ƙwaƙwalwar PCM ba, har na daƙiƙa ɗaya, kamar yadda wannan DTC ke nunawa. Hakanan yana bincika siginar ƙarfin lantarki daga firikwensin FLS don sanin ko daidai ne lokacin da aka kunna maɓallin farko.

Za a iya saita P2069 saboda injin (ba daidai ba matakin man fetur mara kyau; mai da motar tare da kunnawa ko ma injin da ke gudana. Matsayin man yana canzawa da sauri, wanda ba na al'ada ba) ko matsalolin lantarki (FLS sensor circuit). Bai kamata a manta da su ba a lokacin matsala, musamman lokacin ma'amala da wata matsala.

Matakan matsala na iya bambanta dangane da mai ƙera, nau'in firikwensin FLS da launuka na waya. Koma zuwa takamaiman littafin gyara abin hawa don wurin sarkar "B".

Hanyoyin bincike da gyara

Kyakkyawan farawa shine koyaushe samun Bulletin Sabis na Fasaha (TSB) don takamaiman abin hawa. Mai ƙera abin hawa yana iya samun ƙwaƙwalwar ƙwaƙwalwar filasha / sake fasalin PCM don gyara wannan matsalar kuma yana da kyau a bincika kafin ku sami kanku kuna tafiya mai nisa / kuskure.

Sannan nemo firikwensin matakin mai (FLS) akan takamaiman abin hawa. Ana shigar da wannan firikwensin a cikin tankin mai, ko wataƙila ma a saman tankin mai / famfon mai. Da zarar an same shi, a gani a duba mai haɗawa da wayoyi. Nemo karce, goge -goge, wayoyi da aka fallasa, alamomin ƙonawa, ko narkakken filastik. Cire haɗin mai haɗawa kuma a hankali bincika tashoshi (sassan ƙarfe) a cikin mai haɗawa. Duba idan sun ga sun kone ko suna da koren launi wanda ke nuna lalata. Idan kuna buƙatar tsabtace tashoshi, yi amfani da mai tsabtace lambar lantarki da goga na goga. Bada damar bushewa da shafa man shafawa na lantarki inda tashoshin tashoshi ke taɓawa.

Idan kuna da kayan aikin sikirin, share DTCs daga ƙwaƙwalwa kuma duba idan P2069 ya dawo. Idan wannan ba haka bane, to akwai yuwuwar matsalar haɗin gwiwa.

Wannan shine mafi yawan abin damuwa a cikin wannan lambar saboda haɗin tankin mai yana da matsalolin lalata.

Idan lambar P2069 ta dawo, za mu buƙaci gwada firikwensin FLS da da'irori masu alaƙa. Tare da maɓallin kashewa, cire haɗin haɗin wutar lantarki akan firikwensin FLS. Haɗa gubar baƙar fata daga voltmeter na dijital (DVOM) zuwa ƙasa ko ƙaramin tashar tunani akan mai haɗa kayan doki na FLS. Haɗa ja ja daga DVM zuwa tashar siginar a kan haɗin haɗin kayan haɗin FLS. Kunna mabuɗin, injin yana kashewa. Duba ƙayyadaddun masana'anta; voltmeter yakamata ya karanta 12 volts ko 5 volts. Yi haɗin haɗin haɗin don ganin ko sun canza. Idan ƙarfin lantarki bai yi daidai ba, gyara wutar ko waya ta ƙasa ko maye gurbin PCM.

Idan gwajin da ya gabata ya yi nasara, haɗa gubar ohmmeter ɗaya zuwa tashar siginar akan firikwensin FLS sannan ɗayan gubar zuwa ƙasa ko ƙaramin tashar tunani akan firikwensin. Karatun ohmmeter bai kamata ya zama sifili ko iyaka ba. Bincika ƙayyadaddun masana'anta don juriya na firikwensin don bincika madaidaicin matakin mai (1/2 tankin mai na iya karanta 80 ohms).
