Circuit Description
WARNING: This page is about a different car, the 2004 Pontiac Grand Prix. However, it is still accessible from the selected car via links, so may be relevant.
The control module enables the appropriate fuel injector on the intake stroke for each cylinder. Ignition voltage is supplied directly to the fuel injectors through the powertrain power distribution relay and a fuel injector mini fuse. The control module controls each fuel injector by grounding the control circuit via a solid state device called a driver.
