CONNECTION BETWEEN THE POWER ASSISTED STEERING PRESSOSTAT AND THE INJECTION COMPUTER
The injection computer receives information from the power assisted steering pressostat . This varies
depending on the pressure present in the hydraulic circuit. The higher the pressure, , the more energy is
absorbed by the power assisted steering pump.
To compensate for this energy absorption, the injection computer increases the opening ratio of the idle
speed regulation stepping motor.
The information is received on track 13 of the injection computer. If the pressostat is closed , the computer
receives an earth . The idle speed is adjusted to 800 rpm for the D7F engine and 850 rpm for the E7J
engine .
IDLE SPEED CORRECTION DEPENDING ON THE BATTERY VOLTAGE
The objective of this correction is to compensate for the drop in voltage, due to consumer operation when
the battery is poorly charged To correct this, the idle speed is increased, allowing the alternator to rotate
faster and consequently increase the charging voltage.
The lower the voltage, the greater the degree of correction. Correction of the engine speed is therefore
variable. It begins when the voltage drops to below 12.7 Volts. Correction begins at the nominal engine
speed and may reach a maximum of 880 rpm for the D7F engine and 930 rpm for the
E7J engine .
IDLE SPEED CORRECTION DEPENDING ON AIR CONDITIONING OPERATION
The injection computer increases the idle speed to 850 rpm. for the D7F engine and 880 rpm . for the E7J
engine , provided it receives the fast idle speed information from the air conditioning computer.

CLEANING
It is very important not to scratch the gasket faces
of all aluminium components.
Use the product Décapjoint to dissolve the part
of the gasket which remains attached.
Apply the product to the part to be cleaned, wait
approximately 10 minutes, then remove it using a
wooden spatula.
The wearing of gloves is recommended during
this operation.

REMOVAL
Place the vehicle on a two post lift.
Disconnect the battery.
Remove:
- the timing belt (see method described in
section 11 "Timing belt),
- the power assisted steering pump pulley (if fit-
ted),
- the upper alternator mounting bolt and
slacken the lower bolt,
- the bolts for mounting the power assisted
steering pipe on the cylinder block,
- the bolts for mounting the power assisted
steering pump on its support (move the po-
wer assisted steering pump-pipe assembly to
one side),
- the power assisted steering pump support,
- the water pump hose,
- the tension wheel along with the water pump
itself.
