Fuel Injector Resistor: Description and Operation

DESCRIPTION

The fuel injector driver receives an inject command signal from the Powertrain Control Module (PCM) and provides a current regulated output to
the fuel solenoid that controls injection. It also returns an injection pulse width signal back to the PCM to inform it when the fuel solenoid has
actually seated.
