Could you help me with the voltage of equipments in Toyota Common rail engine? As I see we have some voltage 3V, 5V,9V,12V,... 100V ... from EDU (Electronics Driving Unit). Could you clarify and give me some material about that?
Have you checked it with an OB2 scanner? Must of the ones I've checked is 12v. @ the injector. I check both + & - side of the injector. It may be a bad injector, if it doesn't get a reading on both sides. You can go to the ob2 code to get more ideas about it.
