Fuel Injector Wiring Harness: Description and Operation

The fuel charging wiring:

-

connects the engine control sensor wiring to each fuel injector and other electronic engine controls such as Throttle Position sensor (TP sensor)
and Idle Air Control valve (IAC valve).

-

receives fuel injector signals from the Powertrain Control Module (PCM) and transfers the signals to the fuel injectors.

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