CHECKING THE OIL PRESSURE
SPECIAL TOOLING REQUIRED
Mot. 453-01 Hose clamp pliers
Dir. 1204 Pressure test union
Dir. 803 Metric thread union
Fre. 1085
or Pressure gauge
Fre. 244-03
Fre. 284-06 Connecting pipe
Fit clamp Mot. 453-01 to the low pressure pump
hose.
Disconnect the high pressure pipe (take
precautions to catch the oil which will run out).
Insert union Dir. 803 (metric thread) between the
pipe and the pump.
For engines where it is fitted, remove the
pressostat on the rigid pipe (high pressure).
Connect the pressure test union
Dir. 1204 and the oil pressure gauge
Fre. 1085 (or Fre. 244-03 + Fre. 284-06).
77840R1
Connect pressure gauge Fre. 1085 (or Fre. 244-03
+ Fre. 284-06).
Remove clamp Mot. 453-01.
Top up the pump level and run the engine to
check the pressure.
Wheels in straight line:
Regardless of engine speed, the pressure should
not exceed 5 to 7 bars.
Full lock to one side:
Hold the steering at full lock, the maximum
pressure should be 79 to 86 bars.
This operation should not be prolonged to avoid a
high increase in the oil temperature.
Remove union Dir. 803 and pressure gauge
Fre. 1085 or Fre. 244-03 , cutting the supply to the
pump with clamp Mot. 453-01.
Reconnect the high pressure pipe and remove
clamp Mot. 453-01.
Top up the oil in the reservoir.

ANTIPOLLUTION
Fuel vapour recirculation
14
OPERATING PRINCIPLE
The fuel tank is connected to the outside through
the canister.
Fuel vapour is retained by the active carbon in the
canister.
So that the fuel vapour contained in the canister
does not evaporate into the atmosphere when
the fuel tank is opened, a valve isolates the canis-
ter from the fuel tank when the fuel filler cap is
removed.
The fuel vapour contained in the canister is elimi-
nated and burnt by the engine.
To do this, a pipe connects the canister and the in-
let manifold. A solenoid valve is located on this
pipe to control bleeding of the canister.
The operating principle for the solenoid valve is to
give a variable passage diameter (depending on
an RCO signal from the injection computer).
The variation in the selection of passage diameter
for the fuel vapour in the solenoid valve results
from the balance between a magnetic field crea-
ted by the feed to the coil and the force of a re-
turn spring ensuring the valve remains closed.
CONDITIONS FOR CANISTER BLEEDING
During richness regulation
Coolant temperature greater than:
- + 55°C (F3R engine),
- + 15°C (K7M engine),
- + 70°C (E7J engine).
Air temperature greater than:
- - 10°C (F3R engine),
- + 10°C (K7M engine),
- + 20°C (E7J engine).
No load position not recognised (if the throttle
position sensor is faulty, the non-recognition of
the no load condition is replaced by an engine
speed condition
engine speedR > 1500 rpm.).
Outside richness regulation
No load position not recognised.
Coolant temperature less than +15°C for
F3R and
K7M engines (no condition for E7J engine).
If the oxygen sensor is faulty, the canister is bled
when there is no no load.
The cyclical opening ratio for the canister bleed
solenoid valve may be seen using the XR25 and
#23. The solenoid valve is closed for #23 = 0.7 %
(minimum value) except for E7J engines (no #23).

REMOVING THE EGR SOLENOID VALVE
Remove the acoustic tie bar.
Disconnect:
- the air temperature sensor connector (1),
- the oil vapour rebreathing pipe (2).
Slacken the two clips (3) mounting the air duct (4)
and remove it.
Disconnect the accelerator cable (8).

From the solenoid valve, disconnect:
- the vacuum pipe (5),
- the electrical connector (6).Remove the two mounting bolts for the EGR
solenoid valve, then remove the valve.

REFITTING THE EGR SOLENOID VALVE
Renew the seal.
Refitting is then the reverse of removal.
SPECIAL NOTES
To remove the two steel pipes connecting the EGR
solenoid valve mounting to the exhaust manifold
and the inlet manifold, unclip the two clips (9) on
either side of each pipe.
