Switch off the ignition until the end of the power-latch phase, and carry out a road test
followed by a check with the diagnostic tool.

STOREDPRESSURE REGULATION ON RAIL1.DEF: Below minimum threshold
2.DEF: Above maximum threshold
3.DEF: Negative loop deviation
4.DEF: Positive loop deviation
NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after:
– the ignition is switched on,
– with the engine running,
– road test.
Priorities when dealing with a number of faults:
– DF898 Pressure regulator circuit on rail,
– DF897 Pressure regulator circuit on pump,
– DF896 Pressure regulation on pump.
Special notes:
DF895 depends on the pressure regulator built into the rail (DRV).
DF896 Pressure regulation on pump depends on the pressure regulator integrated
in the pump (MPROP).
The fuel pressure regulator built into the rail (DRV) and the fuel pressure regulator built
into the pump (MPROP) are never actuated at the same time.
If the fault is present:
– particle filter regeneration is inhibited,
– the engine stops and the level 2 warning light comes on: 1.DEF, 4.DEF,
–the level 1 warning light comes on: 2.DEF, 3.DEF, 4.DEF,
– engine torque limited 2.DEF, 3.DEF, 4.DEF,
– the rail pressure is regulated by a regulator built into the pump (MPROP): 2.DEF,
3.DEF, 4.DEF.

Check that there are no leaks on the high pressure diesel fuel circuit.
Repair if necessary.
Check the level of fuel in the tank.
Check the low pressure circuit using Test 3 Low pressure circuit test and check that there are no exterior air
leaks in the low pressure fuel circuit.
