Test Note:
All symptoms listed above are diagnosed using the same tests.
The title for the tests will be P1130-FUEL RAIL PRESSURE
MALFUNCTION ACTUATOR STICKING.
When Monitored and Set Condition:
P1130-FUEL RAIL PRESSURE MALFUNCTION ACTUATOR STICKING
When Monitored:
With the ignition on.
Set Condition:
The fuel rail pressure sensor indicates fuel pressure sensor deviation is
too large with the solenoid fully open.
P1130-FUEL RAIL PRESSURE MALFUNCTION LEAKAGE DETECTED
When Monitored:
With the engine running.
Set Condition:
The ECM detects the fuel pressure sensor deviation is too large with the
solenoid closed.
P1130-FUEL RAIL PRESSURE MALFUNCTION POSITIVE DEVIATION
When Monitored:
With the engine running.
Set Condition:
The fuel pressure sensor indicates fuel pressure fuel pressure sensor
deviation at engine speed is too high.
P1130-FUEL RAIL PRESSURE MALFUNCTION PRESSURE TOO HIGH-SHUT
OFF
When Monitored:
With the ignition on.
Set Condition:
The fuel rail pressure sensor indicates fuel pressure above 1450 BAR
(21,000 PSI) at any time.
P1130-FUEL RAIL PRESSURE MALFUNCTION PRESSURE TOO LOW
When Monitored:
With the engine running.
Set Condition:
The ECM determines that the fuel rail pressure is too low for a given
engine speed.

WARNING: HIGH-PRESSURE FUEL LINES DELIVER DIESEL FUEL UN-
DER EXTREME PRESSURE FROM THE INJECTION PUMP TO THE FUEL
INJECTORS. THIS MAY BE AS HIGH AS 23,200 PSI (1600 BAR). USE
EXTREME CAUTION WHEN INSPECTING FOR HIGH-PRESSURE FUEL
LEAKS.
WARNING: FUEL UNDER THIS AMOUNT OF PRESSURE CAN PENE-
TRATE SKIN CAUSING PERSONAL INJURY OR DEATH. INSPECT FOR
HIGH-PRESSURE FUEL LEAKS WITH A SHEET OF CARDBOARD. WEAR
SAFETY GOGGLES AND ADEQUATE PROTECTIVE CLOTHING WHEN
SERVICING FUEL SYSTEM.
Turn the ignition on.
With the DRBIII
t, read the ECM DTCs.
Are there any other DTCs present?
All
Yes
→ Refer to symptom list for problems related to the DTC other than
P1130.
Perform ROAD TEST VERIFICATION - VER-2.
No

NOTE: If the ECM detects and stores a DTC, the ECM also stores the
engine/vehicle operating conditions under which the DTC was set. Some of
these conditions are displayed on the DRB III
t at the same time the DTC is
displayed.
NOTE: Before erasing stored DTCs, record these conditions. Attempting to
duplicate these conditions may assist when checking for an active DTC.
NOTE: Refer to the Service Information and perform the Air Bleed Proce-
dure before continuing diagnosis.
Turn the ignition on.
With the DRBIII
t, erase the ECM DTCs.
NOTE: Driving the vehicle up and down steep hills or rapid cornering with
a low fuel level can cause this DTC to set. Verify with customer if Low Fuel
Light was illuminated when fault occurred.
Test drive the vehicle under various load and speed conditions to attempt to duplicate
the fault.
With the DRBIII
t, read the ECM DTCs.
Does the DRBIII
t display this DTC?

Start the engine.
With the DRBIII
t in Sensors, compare the Fuel Pressure Setpoint with the Actual
Fuel Pressure readings.
NOTE: If there is air in the fuel system, the Actual Fuel Pressure will
oscillate above and below the Fuel Pressure Setpoint.
Does Actual Fuel Pressure oscillate above and below the Fuel Pressure Setpoint?
All
Yes
→ Refer to the Service Information to purge air from the fuel system.
Perform ROAD TEST VERIFICATION - VER-2.
No

Start the engine.
With the DRBIII
t in Sensors, compare the Fuel Pressure Setpoint with the Actual
Fuel Pressure readings.
NOTE: A sticking Fuel Pressure Solenoid is indicated by Actual Fuel
Pressure gradually dropping below the Fuel Pressure Setpoint then sud-
denly increasing (spiking) above the Fuel Pressure Setpoint.
Does Actual Fuel Pressure gradually decrease then suddenly increase (spike) above
the Fuel Pressure
All
Yes
→ Replace the Fuel Pressure Solenoid in accordance with the
Service Information.
Perform ROAD TEST VERIFICATION - VER-2.
