Code and Description    Conditions which Generate this Code    System Response    
1-5 Cylinder #1 : Injector current below normal     The Electronic Control Module (ECM) detects an open circuit.     The code is logged.

6-6 Cylinder #6 Injector : Current Above Normal     The ECM detects a short circuit.     The code is logged.
The ECM will disable the solenoid circuit. The ECM will periodically try to fire the injector. If the short circuit remains, this sequence of events will be repeated until the problem is corrected.    
6-11 Cylinder #6 Injector : Other Failure Mode     The ECM detects a problem in the circuit for the injector.     The code is logged.
The ECM will periodically try to fire the injector. If the problem remains, this sequence of events will be repeated until the problem is corrected.    Perform this procedure under conditions that are identical to the conditions that exist when the problem occurs. Typically, problems with the injector solenoid occur when the engine is warmed up and/or when the engine is under vibration (heavy loads).These engines have Electronic Unit Injectors (EUI) that are mechanically actuated and electronically controlled. The ECM sends a 105 volt pulse to each injector solenoid. The pulse is sent at the proper time and at the correct duration for a given engine load and speed. The solenoid is mounted on top of the fuel injector body.If an open is detected in the solenoid circuit, a diagnostic code is generated. The ECM continues to try to fire the injector. If a short is detected, a diagnostic code is generated. The ECM will disable the solenoid circuit. The ECM will periodically try to fire the injector. If the short circuit remains, this sequence of events will be repeated until the problem is corrected.Note: Refer to Illustration 2. Two injector solenoids share a supply wire. For this reason, an open circuit or a short circuit in a supply wire or a connector could cause diagnostic codes
