CONTINUED 1
Check the connection and condition of the
connector for the fuel pressure solenoid valve
and the computer connector.
Check the insulation, continuity and the absence
of interference resistance on the following
connections:
connection code 3FB1 (or 3FB3 for Kangoo
II) between component 1105 and 983 or 1337,
connection code 3HI between component
1105 and 120.
If the connection or connections are faulty and
there is a repair procedure (see Technical Note
6015A, Electrical wiring repair, Wiring:
Precautions for repair), repair the wiring,
otherwise replace it.
Is the connection OK?
YES
Excitation current >0A?
YES
Contact the Techline.
NOCarry out the necessary repairs.
NOElectrically operated fuel flow solenoid
valve.
Check the main injection relay.
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.

Ignition on, connector connected to fuel rail
pressure sensor.
Measure the feed voltage at the rail pressure
sensor between connection codes 3LX and
3LZ.
Supply voltage of approximately 5V .
Important: do not measure the resistance at the
high pressure sensor. Risk of destruction.
Are the supply voltages and the sensor voltage
correct?
YES
NOIf the supply voltage is incorrect (5 V),
check the connection and condition of the
connector for the rail pressure sensor and
of computer connector C.
Check the insulation, continuity and the
absence of interference resistance on
the following connections:
– connection code 3LY between
components 120 and 1032,
– connection code 3LX between
components 120 and 1032.
If the connection or connections are faulty
and there is a repair procedure (see
Technical Note 6015A, Electrical wiring
repair, Wiring: Precautions for repair),
repair the wiring, otherwise replace it. If
the fault is still present, contact the
Techline.
If the sensor voltage is incorrect, check
the connection and condition of the
connector for the fuel rail pressure sensor
and of computer connector C.
Check the insulation, continuity and the
absence of interference resistance on
the following connections:
– connection code 3LY between
components 120 and 1032,
– connection code 3LZ between
components 120 and 1032.
If the connection or connections are faulty
and there is a repair procedure (see
Technical Note 6015A, Electrical wiring
repair, Wiring: Precautions for repair),
repair the wiring, otherwise replace it.
If the fault is still present, replace the rail
and its sensor and the high pressure
pipes.
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.

With + after ignition feed on, check for + 12 V feed between connection codes 3AHB and M at the electric pump
connector of the particle filter injector, component code 1767.
If there is no + 12 V feed to the sensor, check the continuity, insulation and absence of interference
resistance on the following connections:
●connection code 3AHB between components 1767 and 1768,
●Connection code M between component 1767 and the vehicle earth.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A,
Electrical wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
(Refer to the interpretation of faults DF1004 Electric fuel pump relay control and DF1001 Particle filter
upstream temperature regulation).
●Reconnect or replace the pipe.
Repeat the pressure test.
●Replace the fuel filter (see MR 392, 385, 364, 370 and 417 Mechanics, 13A, Fuel supply, Fuel filter:
Removal - Refitting).
Repeat the pressure test.
●Replace the particle filter injector electric pump.
Repeat the pressure test.
●Check that the particle filter injector is fitted correctly.
Check that the particle filter injector is correctly held in place. Repair or replace the particle filter injector mounting.
●"Only on Kangoo 2:
Check the integrity and correct fitting of the evaporator plate located under the particle filter injector, at the level of
the bracket.
If the blade of the evaporator plate has become detached, it may be located downstream from the line between its
original position and the oxidation catalytic converter inlet.
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.
