PR059INLET AIR TEMPERATURE
PARAMETER
DEFINITIONThis parameter indicates the air inlet 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: Engine stopped and ignition on
With the ignition on the inlet air temperature varies according to the exterior temperature.
In the event of a fault, consult the interpretation of fault DF002 Air temperature sensor circuit.
Parameter PR059 ≈ PR064 Coolant temperature engine cold.
Conformity check with the engine running and engine coolant temperature > 80°C
With the engine running at idle speed the inlet air temperature varies according to the engine coolant temperature.
In the event of a fault, refer to the interpretation of fault DF002.
