IDLE SPEED SETPOINT
PARAMETER
DEFINITIONThis parameter indicates the engine's rotational speed in rpm.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system
operation programming.
Conformity check with engine stopped and ignition on.
With the ignition on the value is 0 rpm.
In the event of a fault, refer to the interpretation of fault DF005 Engine speed sensor circuit.
Conformity check with engine running, engine coolant temperature > 80°C.
With the engine running at idle speed, the value is approximately 800 rpm.
In the event of a fault, refer to the interpretation of fault DF005 Engine speed sensor circuit.
The difference between the idle speed and its setpoint should be less than 50 rpm.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

operation programming.
Conformity check with engine stopped and ignition on.
The value should be:
PR213 = PR008 Rail pressure setpoint – PR038 Rail pressure
In the event of a fault, consult the interpretation of fault DF007 Rail pressure sensor circuit.
Engine running, engine coolant temperature > 80°C.
The value should be:
PR213 = PR008 Rail pressure setpoint – PR038 Rail pressure
