TURBOCHARGING PRESSURE SETPOINT
PARAMETER
DEFINITIONThis parameter indicates the theoretical turbocharging pressure setpoint value for
optimal engine performance in mbar.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system
operation programming.
Conformity check with the engine running at idle speed and engine coolant temperature > 80°C
The theoretical turbocharging pressure value is a setpoint of:
PR009 Turbocharging pressure setpoint = PR041 Turbocharging pressure.
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.

TURBOCHARGING PRESSURE
PARAMETER
DEFINITIONThis parameter indicates the turbocharging pressure in mbar.
NOTESSpecial notes:
Only apply the checks if the parameter is inconsistent.
Use CLIO III, MODUS, MEGANE II ph2, SCENIC II ph2 and KANGOO II Wiring
diagrams Technical Note.
Conformity check with the engine stopped and the ignition on, or the engine running and the engine
coolant temperature > 80°C
With the vehicle ignition on and engine stopped:
– Remove the turbocharger pressure sensor.
– With the sensor connected to the harness, read the value of PR041 from the Parameter screen:
– If the value is not very close to PR035 Atmospheric pressure, maximum pressure difference between
PR035and PR041 with the engine stopped = ± 50 mbar:
Check the insulation and absence of interference resistance on the signal line and the turbocharging
pressure sensor power supply lines.
If the lines are correct, replace the turbocharging pressure sensor.
– Connect a vacuum pump or pressure pump to the turbocharger pressure sensor.
– Apply a pressure of between 0.1 and 1.3 bar (maximum pressure to be applied: 1.3 bar).
– Compare the pressure value displayed in the Parameter screen with that given by the vacuum pump:
If the difference* = ± 0.1 bar, replace the turbocharging pressure sensor.
If there is no discrepancy, the turbocharging pressure sensor is correct.
*Note:
The diagnostic tool displays the absolute pressure, the pressure gauge for the vacuum pump displays
therelative pressure: the normal difference between these two values is equal to the atmospheric pressure,
which is the value of PR035.
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.

tool.
Try to establish dialogue with a computer on another vehicle to check that the diagnostic tool is not faulty. If the
tool is not at fault, and dialogue cannot be established with any other computer on the same vehicle, the cause
could be a faulty computer interfering on the multiplex network.

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 that the power supply to the diagnostic socket is correct:
+ before ignition feed on track 16
