PR041
PARAMETER
DEFINITION This parameter indicates the turbocharging pressure in mbar.
NOTES
Special 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 PR035 and 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 the relative pressure: the normal difference between these two values is equal to the atmospheric pressure, which is the value of PR035.
