Fault finding – Interpretation of parameters13B
PR009TURBOCHARGING PRESSURE SETPOINTS
PARAMETER
DEFINITIONThis parameter indicates the theoretical turbocharging pressure setpoint value in bar.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system
operation programming.
Conformity check: Engine stopped and ignition on, or Engine running, and engine coolant
temperature > 80°C
The theoretical turbocharging pressure value is a setpoint of:
PR009 ≈ 1 bar.

PR209TURBOCHARGING PRESSURE LOOP DIFFERENCE
PARAMETER
DEFINITIONThis parameter indicates the turbocharging pressure loop difference in bar.
NOTESNone.
Conformity check: Engine running, engine coolant temperature > 80°C, without electrical consumers.
The turbocharging pressure loop difference value must be:
PR209 = PR009 Turbocharging pressure setpoint - PR041 Turbocharging pressure = ~ 0.
If PR209 is significant, refer to the interpretation of the command AC004 Turbocharging solenoid valve.
