PR064COOLANT TEMPERATURE
PARAMETER
DEFINITIONThis parameter indicates the engine coolant temperature in °C.
NOTESThere must be no present or stored faults.
Perform this fault finding procedure:
– after finding an inconsistency in the parameter,
– after a customer complaint (e.g. lack of power).
Use the Technical Note Wiring Diagram, Laguna II ph2, Vel Satis ph2, Mégane ll
ph2, Scénic ll ph2, Espace IV ph2.
Conformity check with engine stopped and ignition on.
With the ignition on the coolant temperature varies according to the exterior temperature.
In the event of a fault, consult the interpretation of fault DF001 Coolant temperature sensor circuit.
Parameter PR059: Inlet air temperature ≈ PR064 engine cold.
Conformity check with the engine running and engine coolant temperature > 80°C
With the engine running at idle speed the coolant temperature varies according to the engine temperature.
If there is a fault, refer to the interpretation of fault DF001.
