NOTESConditions for applying the fault finding procedure to stored faults:
The fault appears after a timed period of 10 seconds with the engine running
at 2000 rpm.
Special notes:
Use bornier Elé. 1681 for all operations on the computer connectors.
Disconnect the battery.
Disconnect the modular connector, and check the cleanliness and condition of the connections.
Disconnect the computer. Check the cleanliness and condition of the connections.
Repair if necessary.
Check the insulation, continuity and the absence of interference resistance to earth, to + 12 V of the following
connection:
●connection code 5U, between components 119 and 781.
With the ignition on, check for + 5 V on connection 5U of the oil pressure sensor connector.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring. Otherwise replace the wiring.
●connection code 5W, between components 119 and 781,
●connection code 5V, between components 119 and 781.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring. Otherwise replace the wiring.
The voltage on connection 5U of the modular connector must be + 5 V, otherwise check the computer supply.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring. Otherwise replace the wiring.
Reconnect the modular connector.
Measure the resistance of component 781 between connections 5V and 5W on the computer connector (female
connector).
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring. Otherwise replace the wiring.
Replace the sensor if the resistance is not approximately 20 kΩ.
If the problem is still present, contact the Techline.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
tool.

NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present following a delay of 5 seconds, with the engine running,
the vehicle stationary with a gear engaged and a difference of more than 384 rpm
between the engine speed and the turbine speed.
Special notes:
Use bornier Elé. 1681 for all operations on the computer connectors.
Use the Mégane II or Scénic II wiring diagram Technical Note.
Check the oil level in the engine and gearbox.
Top up if necessary (see MR 364 Mechanical, 23A, Automatic transmission, Filling-levels (for Mégane II) and
MR 370 Mechanical, 23A, Automatic transmission, Draining-Filling (for Scénic II)).
Check the engine speed:
–Possible engine speed instability
–Deal with the faults displayed on the diagnostic tool for the injection computer.
Deal with the other faults first.
Check the turbine speed:
–Possible inconsistency with the turbine speed,
–Possible turbine sensor fault,
–Possible solenoid valve oil pressure fault.
Check the oil pressure with the engine switched off using PR003 Oil pressure: if the pressure is greater than
0.2 bars, replace the pressure sensor.
–Warm engine with gearbox oil temperature between 65 and 90˚C.
–Measure the line pressure under the 3 following conditions:
IMPORTANT
The vehicle must be stationary: handbrake on and brake pedal depressed, no accessories operating
(e.g.: air conditioning)
1Engine speed idling:
Shift the gear lever to R, N and D, the pressure reading must be greater than 2.5 bar.
2Engine speed at 1200 rpm:
–gear lever in R position, the pressure reading must be greater than 4 bar.
–gear lever in D position, the pressure reading in first gear must be greater than 5.5 bar.
3Engine speed at 2200 rpm:
–gear lever in R position, the pressure reading must be greater than 11 bar.
–gear lever in D position, the pressure reading in first gear must be greater than 11 bar.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
tool.

Use the Mégane II or Scénic II wiring diagram Technical Note.
Check the quality and level of the gearbox oil (see MR 364 Mechanical, 23A, Automatic transmission, Filling - levels
(for Mégane II) and MR 370 Mechanical, 23A, Automatic transmission, Oil change (for Scenic II)).
Check that the gearbox is not leaking oil.
Carry out the converter setting point test.
To locate the cap position, consult MR 364, Mechanical, 23A, Automatic transmission, Line pressure
measurement (for Mégane II) and MR 370, Mechanical, 23A, Automatic transmission, Line pressure
measurement (for Scénic II).
Check the oil pressure with the engine switched off using PR003 Oil pressure: if the pressure is greater than
