1-216
DTC 1174-EPR/CFV Voltage Supply High
• Hardware: EPR (HD EPR) or CFV
• Enabling Conditions: Engine Running
• Set Conditions: Voltage supply to EPR is higher than 33.0 VDC for longer than 5 seconds.
• Corrective Action(s): Illuminate MIL, AL disable, AL disable in key-cycle, power derate 2, Low rev limit
• Emissions related fault
• Possible Causes: Wiring harness open,short or damage
DTC 1175-EPR/CFV Voltage Supply Low
• Hardware: EPR (HD EPR) or CFV
• Enabling Conditions: Engine Running
• Set Conditions: Voltage supply to EPR is lower than 18.0 VDC for longer than 5 seconds.
• Corrective Action(s): Illuminate MIL, AL disable, AL disable in key-cycle, power derate 2, Low rev limit
• Emissions related fault
• Possible Causes: Wiring harness open,short or damage, Faulty EPR power circuit
DTC 1176-EPR/CFV Internal Actuator Fault Detection
• Hardware: EPR (HD EPR) or CFV
• Enabling Conditions: Engine Running
• Set Conditions: Internal Actuator Fault detected
• Corrective Action(s): Illuminate MIL, AL disable
• Emissions related fault
• Possible Causes: Short or open circuit in actuator coil, Associated wiring, Overheating of actuator drive
electronics
If the EPR/CFV does not trigger either 1171, 1172, or either of the CFV Flow fault code(s), there is no issue with
the EPR/CFV. If one or more of these faults are triggered, refer to the appropriate section for diagnostic information.
DTC 1177-EPR/CFV Internal Circuitry Fault Detection
• Hardware: EPR (HD EPR) or CFV
• Enabling Conditions: Engine Running
• Set Conditions: Internal circuitry fault detected
• Corrective Action(s): Illuminate MIL, AL disable
• Emissions related fault
• Possible Causes: DEPR internal microprocessor or memory failure, fuel temperature sensor failure
If the EPR/CFV does not trigger either 1171, 1172, or either of the CFV Flow fault code(s), there is no issue with
the EPR/CFV. If one or more of these faults are triggered, refer to the appropriate section for diagnostic information.
