Code P119, Open/Shorted Fuel Injector: Notes
WARNING: This page is about a different car, the 1995 Cadillac Eldorado. However, it is still accessible from the selected car via links, so may be relevant.
PCM contains a General Field Effect Transistor Driver (GFD) that control the 8 fuel injector drivers. GFD detects circuit problems with any of the 8 fuel injectors. If any circuit exists, PCM sets trouble code and also sets the second digit of parameter PD17 HI (1) and disables the faulty injector of the engine cycle.
