NOTESConditions for applying the fault finding procedure to a stored fault:
The fault becomes present after starting the engine.
If the fault is present:
–The level 1 and OBD fault warning lights are lit on the instrument panel.
–The cruise control/speed limiter is inhibited.
– Loss of performance, torque setpoint restricted.
Use CLIO III, MODUS, MEGANE II ph2, SCENIC II ph2 and KANGOO II Wiring
diagrams Technical Note.
Check the condition and connection of the turbocharging pressure sensor connector, component code 1071.
If the connector is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Check the connection and condition of the injection computer connector, component code 120 (see MR 392,
385, 364, 370 and 417, Mechanical, 13B, Diesel injection, Diesel injection computer: Removal - Refitting).
If the connector is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
With the ignition on, check for + 5 V on connection 3LQ and earth on connection 3LN of the turbocharging
pressure sensor.
If the connection(s) are faulty and there is a repair method (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check the insulation, continuity and the absence of interference resistance on the following connections:
–3LQ between components 1071 and 120,
–3LN between components 1071 and 120,
–3LP between components 1071 and 120.
If the connection(s) are faulty and there is a repair method (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check the consistency between the atmospheric pressure and the turbocharging pressure (PR035
Atmospheric pressure = PR041 Turbocharging pressure
).
Engine stopped (cold), the pressure read by the two sensors must be nearly the same.
If the values are very different, replace the turbocharging pressure sensor.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any faults displayed by the diagnostic tool.
Clear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool.

ENGINE TORQUE
PARAMETER
DEFINITIONThis parameter indicates the engine torque in Nm.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system
operation programming.
Conformity check with the engine running and engine coolant temperature > 80°C
This value should be between:
20 N.m. < PR015 < 40 N.m.
This parameter is only valid when the engine is running.
AFTER REPAIRDeal with any faults displayed by the diagnostic tool.
Clear the computer memory.
Carry out a road test followed by another check with the diagnostic tool.
