STOREDGEARBOX OIL PRESSURE REGULATION
1.DEF : Pressure regulation
NOTESCarry out injection system fault finding and check that it is operating correctly.
If the following faults are present or stored, deal with them first:
–DF003 Sensor feeds.
–DF005 Oil pressure sensor circuit.
–DF023 Gearbox oil temperature sensor circuit.
–DF036 Pressure modulating solenoid valve circuit.
–DF038: Turbine speed sensor circuit.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present after a road test.
To make sure there are no problems with the pressure lock-up solenoid valve, use the interpretation of fault DF036
Pressure regulating solenoid valve circuit.
Check gearbox oil grade and level.
If an operation is 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 that the gearbox is not leaking oil.
Carry out a conformity check to detect any possible faults.
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.

●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.
●Take the line pressure reading under the following 3 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 bars.
2Engine speed at 1200 rpm:
–gear lever in R position, the pressure reading must be greater than 4 bars.
–gear lever in D position, the pressure reading in first gear must be greater than 5.5 bars.
3Engine speed at 2200 rpm:
–gear lever in R position, the pressure reading must be greater than 11 bars.
–gear lever in D position, the pressure reading in first gear must be greater than 11 bars.
If the line pressure value read 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
flashing for the adjustment of the ball detent blade.
If the fault 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.
