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.
