Consider Impedence to be another term for resistance (just for this thread). Lower impedence dictates a higher current flow is required to properly actuate (open/close) the injector. Jun 14, 2023 · With the key in the on position use a test light or voltmeter connected to the negative side of the battery. Gently probe both sides of the injector wiring connector, one of the wires should react by registering around 12 volts on the meter or illuminating the test light. If neither wire reacts test the fuel injector fuse in the PDC.

Fuel Injector Spotters Guide and Information The flow rates shown are at 100% duty cycle (static) and are for gasoline.
