Circuit Description
WARNING: This page is about a different variant/trim than selected.
The engine control module (ECM) enables the appropriate fuel injector pulse for each cylinder. Ignition voltage is supplied to the fuel injectors. The ECM controls each fuel injector by grounding the control circuit via a solid state device called a driver. The ECM monitors the status of each driver. If the ECM detects a high voltage for the commanded state of the driver, DTC P0262, P0265, P0268, P0271, P0274, P0277, P0280, P0283 sets.
