PARAMETER
DEFINITIONThis parameter indicates the air inlet temperature in ˚C.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system operation
programming.
There 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).
Conformity check with engine stopped and ignition on.
With the ignition on the inlet air temperature varies according to the exterior temperature.
Parameter PR059 ≈ PR064 Coolant temperature engine cold.
In the event of a fault, apply the interpretation of DF089 Inlet manifold pressure sensor circuit.
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, apply the interpretation of DF089.

PARAMETER
DEFINITIONGives the vehicle speed in km/h.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system operation
programming.
This parameter is transmitted by the ABS computer. This signal is transmitted to the
injection on the multiplex network.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant
temperature > 80˚C
In the event of a fault, test the multiplex network (see 88B, Multiplex).
Then complete fault finding on the ABS computer (see 38C, Anti-lock braking system).

PR090IDLE SPEED REGULATION PROGRAMMING VALUE
PARAMETER
DEFINITIONThis parameter indicates the idle speed regulation programming value as a %.
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, or engine running, and engine coolant
temperature > 80˚C
PR090 is a stored parameter designed to "program" dispersion and engine ageing for the idle speed regulator.
The programming is carried out only when the engine is idle and warm, and no electrical consumer
(air conditioning, fan assembly, power assisted steering) is operating. Therefore it adjusts slowly.
