【Injector Tester & Injector Cleaner】CODIAG GT 101 Power Digital Tester has a DIY injector cleaning adapter kit, which supports DIY cleaning of injectors. When the fuel injector is driven to open and close, and the current shows a normal value, it means that the fuel injector is normal. If it does not move or the current display is abnormal, it means that the injector is damaged. When checking the injector for clogging, it can be cleaned by cleaning the pressurized tank with the injector..
