NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present following a road test or after attempting to start the engine
several times.
Special notes:
If the fault is present:
– the EGR functions and passenger compartment heating resistance functions
are inhibited,
– the engine speed is limited,
–the level 1 warning light is lit.
– The OBD warning light will come on after three consecutive cycles
(starting + 5 seconds + switch off the ignition and wait 40 seconds).
Use bornier Ele. 1681 for all operations on the injection computer connectors.
WARNING
This fault may appear if the wiring harness has been damaged. Follow the procedure described in the
Wiring Check in the Introduction. This check enables the condition and the conformity of the engine wiring
harness to be checked.
The sensors connected to supply no.2 are:
–EGR valve position sensor,
–track 2 of the accelerator pedal potentiometer sensor,
–refrigerant pressure sensor.
To locate a faulty sensor and/or connection, disconnect one of these sensors then check whether the fault
becomes stored.
If the fault is still present, repeat the operation with the other sensors.
(wait a few seconds between each disconnection to allow the computer to perform the measurement).
If the fault is stored after a disconnection, replace the faulty sensor or repair its connection.
Clear the faults created by the multiple disconnections.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by a check with the diagnostic tool.

NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present with the engine running and a heating and air
conditioning request
Priorities when dealing with a number of faults:
Firstly, deal with the following faults:
– DF049 Refrigerant sensor circuit 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 if 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: check,
Refrigerant circuit: Draining - Filling).
AFTER REPAIRDeal with any faults.
Carry out a road test, then check with the diagnostic tool.
