Fuel Injector Wiring Harness: Description and Operation
PURPOSE
The fuel charging wiring connects the engine wiring harness to each fuel injector and other electronic engine controls such as throttle position
sensor and idle air control valve.
OPERATION
It receives fuel injector signals from the powertrain control module 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.
