Fuel Charging Wiring

The fuel charging wiring (9D930) :

• Connects the engine wire harness to each fuel injector (9F593) or other electronic engine controls such as throttle position sensor (TP sensor) (9B989) and idle air control valve (IAC valve) (9F715) .
• Receives fuel injector signals from the powertrain control module (PCM) (12A650) and transfers the signals to the fuel injectors .

The signals from the powertrain control module determine the fuel injection sequence and the duration each fuel injector will stay open to allow fuel into the combustion chambers.
