Mene ne wannan yake nufi?

Wannan Tsarin Jini / Injin DTC galibi ya shafi duk injunan da ke sanye da kayan OBD-II, amma ya fi yawa a wasu Dodge / Chrysler / Jeep, General Motors da Toyota motocin.

Ana samun firikwensin firikwensin matsa lamba / canzawa (TFPS) a haɗe zuwa gefen jikin bawul ɗin a cikin watsawa, kodayake ana iya samun sa a wani lokacin da aka saka shi a gefen akwati / gidan kansa.

TFPS tana jujjuya matsin watsa na inji zuwa siginar lantarki don tsarin sarrafa wutar lantarki (PCM) ko tsarin sarrafa watsawa (TCM). Yawanci, PCM / TCM zai sanar da sauran masu sarrafawa ta amfani da bas ɗin abin hawa.

PCM / TCM tana karɓar wannan siginar ƙarfin lantarki don ƙayyade matsin aiki na watsawa ko lokacin canjin kaya yana faruwa. An saita wannan lambar idan wannan shigarwar ba ta dace da wutar lantarki ta al'ada da aka adana a ƙwaƙwalwar PCM / TCM ba. Hakanan yana iya kasancewa saboda matsalolin injin cikin gida a cikin watsawa.

P0879 galibi matsalar keɓaɓɓiyar wutar lantarki ce (ƙarar firikwensin TFPS), kodayake, kamar yadda aka fada a baya, ana iya saita wannan lambar saboda matsalolin injiniya (ɓoyayyun ciki, fasa ko ɓoyayyun gwajin gwaji a cikin bawul ɗin, ƙarancin tsarin aiki / matsin lamba a layin, bawul ɗin ya makale a jikin bawul ɗin). Bai kamata a manta da wannan ba a lokacin matsala, musamman lokacin ma'amala da wata matsala.

Matakan matsala na iya bambanta dangane da mai ƙera, nau'in firikwensin TFPS, da launuka na waya.

Sannan nemo firikwensin / juyawa akan abin hawan ku na musamman. TFPS galibi ana samunsa a haɗe da gefen bawul ɗin da ke cikin watsawa, kodayake ana iya samun sa a wani lokaci a saka shi a gefen akwati / gidan kansa. 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.
