PR190IDLE SPEED SETPOINT
PARAMETER
DEFINITIONThis parameter indicates the engine's rotational speed in rpm.
NOTESNone.
Conformity check with engine stopped and ignition on.
With the ignition on, the engine speed value must be:
PR190 = 800 rpm or PR190 = 850 rpm (depending on the vehicle).
In the event of a fault, refer to the interpretation of faults DF195 Camshaft sensor / engine speed consistency,
DF119 Camshaft sensor signal and DF120 Engine speed sensor signal.
Conformity check with the engine running and engine coolant temperature > 80°C
With the engine running at idle speed, the engine speed value must be:
PR190 = 800 rpm or PR190 = 850 rpm (depending on the vehicle).
In the event of a fault, refer to the interpretation of faults DF195, DF119 and DF120.
The difference between the engine idle speed and its setpoint must be less than 50 rpm.
