An katange injector don silinda 6

Mene ne wannan yake nufi?

Wannan sigar lambar rikitarwa ce mai rikitarwa (DTC) kuma galibi ana amfani da ita ga motocin OBD-II. Wannan na iya haɗawa, amma ba'a iyakance shi ba, motocin Ford (Transit, Focus, da sauransu), Land Rover, Mitsubishi, Maybach, Dodge, Subaru, da dai sauransu Duk da yanayin gabaɗaya, ainihin matakan gyara na iya bambanta dangane da shekarar da aka ƙera , iri, samfuri da watsawa. sanyi.

Idan abin hawa na OBD-II ɗinku ya adana lambar P02B0, yana nufin cewa tsarin sarrafa wutar lantarki (PCM) ya gano yiwuwar ƙuntatawa a cikin injector na mai don takamaiman silinda na injin, a wannan yanayin silinda # 6.

Injectors na mai na mota suna buƙatar matsin lamba na mai don isar da ainihin adadin mai a cikin madaidaicin tsari zuwa ɗakin ƙona kowane silinda. Bukatun wannan madaidaiciyar da'irar na buƙatar kowane injector na mai ya kasance ba tare da ɓarna da ƙuntatawa ba.

Kwamfutar PCM tana lura da dalilai kamar datsa man da ake buƙata da kuma bayanan firikwensin iskar oxygen, tare da matsayin crankshaft da matsayin camshaft, don gano cakuda mai ɗorawa da gano abin da injin silinda ke aiki mara kyau.
