Check the air flow:
●The air flow must be approximately 250 mg/st.
Check the air flowmeter connector, component code 799 (corrosion, fouling, etc.).
If the connector is faulty and there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the connector(s), otherwise replace the wiring.
Check the continuity, insulation and absence of interference resistance on the following connections:
●Code connection 3FB (3FB3 for Kangoo II) between components 799 and 1768.
●Connection code 3ABQ between components 799 and 120.
●Connection code 3DV between components 799 and 120.
●Connection code 3KJ between components 799 and 120.
●connection code 3DW between components 799 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.
Check the particle filter injector supply system by running Test 8 Particle filter injector supply circuit check.

Particle filter injector fuel system pressurisation check (pressure test):
To check the pressure in the particle filter injector fuel system:
●Connect the T-union Mot 1311-08 to the particle filter injector fuel filter outlet (adapter visible without
dismantling).
●Connect the pressure gauge Mot 1311-01 to the T-union.
Pressurise the fuel system using the diagnostic tool, and run command AC237 Fuel pump relay.
If the pressure in the system is about 1 bar, perform the command a second time.
The pressure must be at least 3 bar.
If the fuel pressure is less than 3 bar, proceed as follows:
●Carry out a visual inspection of the flexible supply hose to the particle filter injector, before and after the
T-union (leaks, pinching, fuel filter condition, etc.).
Pressurise the fuel system again with the diagnostic tool, and run command AC237 Fuel pump relay.
If the pressure is not equal to or above 3 bar, replace the pump/sender unit (see Technical Note 5117A, Special
features of vehicles fitted with the K9K 772 engine).
Checking the pressure regulator:
●Run command AC237 Fuel pump relay, until the fuel pressure reaches 5 bar.
●Reactivate command AC237 Fuel pump relay again to check that the pressure is controlled between 5.5 bar
and 5 bar.
If the regulator is not working, replace the pump/sender unit (see Technical Note 5117A, Special features of
vehicles fitted with the K9K 772 engine).
Note:
To reduce the pressure in the system, run command AC238 Particle filter injector, until it drops to 3 bar, then
carefully disconnect the union.
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.

1 - NO particle filter regeneration.
2 - Write on the repair order: the parameter and status relating to the last failure:
– Mileage of last Particle filter warning light record
– Mileage of last Failed regeneration records
– Engine statuses for last Engine status records
Example: PR837 = 2794 miles (4657 km); PR801 = 2760 miles (4600 km); engine status = STOPPED
3 - Interpretation of the values written on the repair order by the service advisor for the customer:
Before the last time the warning light or Particle Filter message came on (appeared at the mileage of the last
Stored particle filter warning light) the customer did not follow the driving instructions: the failure which
occurred at the Mileage of the last failure was due to the engine being switched off.
4 - Service advisor explains to the customer the procedure to turn off the warning light, backed up by the
parameters written in the repair order: see PA R T D.

1 - Carry out a regeneration in the Renault dealership with the approval of the Techline.
Follow the procedure for command SC017 Particle filter regeneration.
Note: Do not carry out an engine oil change following an After-Sales regeneration.
