Gwajin fitar da hayaki ya gaza? Gyara Lambobin OBD-II gama gari guda 10 Kafin Bincikenku na gaba

Motocin zamani sun dogara da tsarin On-Board Diagnostics II (OBD-II) don lura da aikin injin da fitar da hayaki. Lokacin da motarka ta gaza gwajin hayaki, tashar binciken OBD-II ta zama mafi kyawun kayan aikin ku don ganowa da warware batutuwa. A ƙasa, mun bayyana yadda na'urar daukar hotan takardu na OBD-II ke aiki da kuma samar da mafita ga lambobin matsala guda 10 waɗanda zasu iya haifar da gazawar hayaki.
