Hello, my name is***** code sets when the ECM detected a circuit fault related to the high voltage circuit to cylinders 2, 3, 5 or 8. The fuel injection control module (FICM) supplies high voltage to each fuel injector on the ignition voltage circuits. This code usually means a injector has failed but would typically set with a specific injector code. If this is the only code your getting it would point toward a problem with the fuel injection control module. Let me know if you have more questions, thanks.
Then this would point toward #2 injector. Let me know if you have more questions, thanks.
