●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.

With a warm engine and the gearbox oil temperature between 60 and 80 ˚C, check the difference between the line
pressure sensor (PR003) and the pressure gauge under the following conditions:
–with the engine stopped, the pressure gauge should indicate a residual pressure of about 0.2 bar.
If the sensor reading differs by more than 0.2 bar, replace the sensor.
–with the engine running at about 1200 rpm the pressure gauge reading should reach 7 bar.
If the sensor reading differs by more than 0.8 bar, replace the sensor.
Warm engine with gearbox oil temperature between 60 and 80 ˚C.
Take the line pressure readings under the following conditions:
–with the gear lever in P or N and engine speed at 2000 rpm the pressure should be between 2.6 and 3.2 bar.
–with the gear lever at R and engine speed at 2000 rpm, the pressure should be above 4 bar.
