E396 High Fuel Rail Pressure
Conditions Which Generate This Code:
The Electronic Control Module (ECM) detects
excessive fuel rail pressure. The ECM detects the
following problems:
•
The ECM detects fuel rail pressure that is more
than the pressure that is required for the operating
conditions.
•
Diagnostic code 0262-03 5 Volt Sensor DC Power
Supply voltage above normal is not active.
•
Diagnostic code 0262-04 5 Volt Sensor DC Power
Supply voltage below normal is not active.
•
Diagnostic code 1797-03 Fuel Rail Pressure
Sensor voltage above normal is not active.
•
Diagnostic code 1797-04 Fuel Rail Pressure
Sensor voltage below normal is not active.
•
No diagnostic codes are active for the fuel rail
pump.
•
No diagnostic codes are active for the fuel injectors.
System Response:
The event code will be logged.
The optional warning lamp will be illuminated.
Possible Performance Effect:
The engine will be derated until the keyswitch is
turned to OFF.
Troubleshooting:
The event code does not represent a problem with
the electronic system. This event indicates high fuel
pressure. Refer to Testing and Adjusting Manual,
“Fuel System - inspect”.
A failed relief valve, the fuel pump or an electronic
unit injector may cause an event code to be logged.
Results:
•
OK – STOP.

E398 Low Fuel Rail Pressure
Conditions Which Generate This Code:
The Electronic Control Module (ECM) detects a
problem with low fuel rail pressure. The ECM detects
the following problem:
•
The ECM determines that the expected fuel
rail pressure is lower than the pressure that is
requested by the electronic control system.
•
Diagnostic code 0262-03 5 Volt Sensor DC Power
Supply voltage above normal is not active.
•
Diagnostic code 0262-04 5 Volt Sensor DC Power
Supply voltage below normal is not active.
•
Diagnostic code 1797-03 Fuel Rail Pressure
Sensor voltage above normal is not active.
•
Diagnostic code 1797-04 Fuel Rail Pressure
Sensor voltage below normal is not active.
•
No diagnostic codes are active for the fuel rail
pump.
•
No diagnostic codes are active for the fuel injectors.
System Response:
The event code will be logged.
The optional warning lamp will be illuminated.
Possible Performance Effect:
The engine will be derated until the keyswitch is
turned to OFF.
Troubleshooting:
Low fuel pressure may be caused by the following
problems. There can be a problem with the fuel
return system. There can be a problem with the fuel
pressure control. There can be a leak in the high
pressure fuel system.
A failed relief valve, the fuel pump or an electronic
unit injector may cause an event code to be logged.
The event code does not represent a problem with
the electronic system. This event indicates low fuel
rail pressure. Refer to Testing and Adjusting Manual,
“Fuel System - Inspect”.
Results:
•
OK – STOP.
