If the line pressure recorded under one of these 3 conditions is incorrect, replace the line pressure sensor
If the line pressures recorded under these 3 conditions are good, then the pressure sensor is operating correctly.
Replace the pressure regulating solenoid valve.
If the fault is still present after the pressure regulating solenoid valve has been replaced, replace the hydraulic
distributor and during refitting, take into account Technical Note 4194A Automatic transmission indicator strip

NOTESConditions for applying the fault finding procedure to stored faults:
The fault appears after running command AC024 Sequential actuator control.
If the following faults are present or stored, deal with them first:
–DF003 Analogue sensor supply.
–DF005 Oil pressure sensor circuit.
–DF016 Lock-up solenoid valve circuit.
–DF177 Automatic transmission overheating.
–DF226 Automatic transmission internal pressure.
–DF244 Turbine speed sensor signal
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
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.

Conditions for applying the fault finding procedure to stored faults:
Safe mode is triggered after a fault, not by the driver.
In particular, check that there are no faults on:
–the turbine speed sensor, DF244 Turbine speed sensor signal.
–the vehicle speed signal, DF230 Invalid vehicle speed multiplex signal.
Check that PR003 “Oil pressure” equals 21 bar. (forced setpoint)
Possible defective components:
Slave cylinder (brakes, clutch) or computer.
Then check cleanliness and condition of the gearbox oil.
If the fault is still present, contact Techline.
