Conditions for applying fault finding procedures to stored faults:
The fault is present with the engine running.
See the Technical Note Wiring Diagrams for the vehicle.
Check the presence and conformity of the fuel, run TEST 13: Diesel fuel conformity check.
Check the connection and condition of the flow actuator connector, component code 1105.
If the connector is faulty and there is a repair procedure (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Check for + 12 V (after relay) on connection 3FB1 or 3FB2 (for New Twingo) or 3FB3 (for Kangoo 2) of
component 1105.

code 120.
If the connector is faulty and there is a repair procedure (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Measure the resistance between connections 3HI and 3FB1 or 3FB2 (for New Twingo) or 3FB3 (for Kangoo 2)
of component 1105.
If the resistance of the flow actuator is not between 4.8 Ω and 5.8 Ω at 20
°C, replace the flow actuator, component
code 1105 (see MR 364 (Mégane II), MR 370 (Scénic II), MR 385 (Modus), MR 392 (Clio III), MR 411

K9K 766, 768, 724, 740, 800, 802, and 812 ENGINES (Euro 4):
Check the connection and condition of the EGR valve connector, component code 1460.
Check the connection and condition of connector B (brown 48-track) of the injection computer, component
code120.
If the connector(s) is faulty and if there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Check the insulation and continuity of the following connections:
–3VP between components 1460 and 120,
–3VQ between components 1460 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 the wiring.
Check for +5 V on connection 3GC of component 1460.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.

NOTESPriority when dealing with a number of faults:
If there is a combination of the following faults:
–DF121 Accelerometer sensor circuit,
–DF001 Coolant temperature sensor circuit,
–DF002 Air temperature sensor circuit,
–DF003 Atmospheric pressure sensor circuit,
–DF098 Fuel temperature sensor circuit,
–DF026 Cylinder 1 injector control circuit,
–DF027 Cylinder 2 injector control circuit,
–DF028 Cylinder 3 injector control circuit,
–DF029 Cylinder 4 injector control circuit,
Deal first with faults DF026, DF027, DF028, and DF029 (1.DEF - 2.DEF).
A fault on these sensors could lead to incorrect fault finding on the accelerometer.
Conditions for applying the fault finding procedure to a stored fault:
The fault is present with the engine running.
See Technical Note Wiring Diagrams of the vehicle concerned
Check the conformity of the injectors fitted to the vehicle in relation to the type of vehicle and engine number
(low, high or very high pressure injector).
Check the connection and condition of the accelerometer connector, component code 146.
Check the connection and condition of connector B (brown 48-track) of the injection computer, component
code 120 and the sensor shielding on connection TB1.
If the connector(s) is faulty and if there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Check the insulation and continuity of the following connections:
–3DQ between components 146 and 120,
–3S between components 146 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 the wiring.
