Motorised
throttlePR090:Idle speed
regulation
programming
valuePR090≈ 0%
PR090, an adaptive built-in
action, is a stored parameter
designed to program variation
and engine ageing for the idle
speed regulator. These are
programmed only when the
engine is idling and warm, and
no electrical consumers
(electrical windscreen, air
conditioning, GMV, power
steering) have been selected.
Therefore it adjusts slowly.WITHOUT
6 PR091:Theoretical idle
speed regulation
OCR5% When the conditions for
regulation are met, the idle
regulator continually
repositions the motorised
throttle to keep the engine
speed at the idling speed
setting. The motorised throttle
opening ratio required to adhere
to the engine speed setpoint is
then given by parameter PR091.

NOTESThere must be no present or stored faults.
Check the cleanliness and condition of the refrigerant pressure sensor and its connections.
Repair if necessary.
Disconnect the battery and the injection computer.
Check the cleanliness and condition of the connections.
Using the universal bornier in place of the computer, check for insulation and continuity on the following
connections:
Computer, connectorB, track J2 track B of the refrigerant sensor
Computer, connectorB, track J3 Track C of the refrigerant sensor
Computer, connectorB, track K2 track A of the refrigerant sensor
Repair if necessary.
If the fault is still present, replace the refrigerant fluid sensor.
If the fault is still present, check the air conditioning circuit (see MR 366 or 370 Mechanics, 62A,
Air conditioning).
AFTER REPAIRRepeat the conformity check from the start.
