NOTESConditions for applying fault finding procedures to stored faults:
The fault is declared present with the engine running and with a heating and air
conditioning system request.
Priorities when dealing with a combination of faults:
Deal with fault DF232 Refrigerant pressure sensor circuit first if it is present or
stored
When the fault is present or stored, the heating and air conditioning system is inhibited.
Check fuse F22 (10A) of the UPC and the condition of the air conditioning compressor connector.
If the connector is faulty and there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Check the air conditioning compressor wiring.
If the wiring is faulty and there is a repair procedure (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
Manually check whether the compressor is jammed (turn the clutch plate manually to check that there is no point
of resistance). In the event of sticking, replace the air conditioning compressor (see MR 364 (Mégane II) or 370
(Scénic II), Mechanical, Heating and air conditioning system, 62A, Air conditioning, Compressor:
Removal - Refitting).
Top up with freon, check for any leaks and repair if necessary (see MR 364 (Mégane II) or 370 (Scénic II),
Mechanical, Heating and air conditioning system, 62A, Air conditioning, Refrigerant circuit: checks,
Refrigerant circuit: Draining - Filling).
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition, wait 1 minute and carry out a road test followed by another
check with the diagnostic tool.

programming value- 12% < PR090 < 12%
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
5Motorised
throttlePR091:Theoretical idle
speed regulation
OCR0% < PR091 < 60%
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.
