1 Trip mileometer reset button and clock reset (rotate).
NOTE :
• Under normal operating conditions, the oil level is only measured if the ignition has been switched off for
over one minute; otherwise the old oil level value is re-displayed.
If a fault is detected, however, an oil level measurement is made each time the ignition is switched on to
check if the fault is persisting.
• It is normal to find that the oil level is not always the same:
- parking on a slope,
- too short a wait after running the engine for a short moment (especially when the oil is cold), ...

Tighten the mounting nut on the fuel and sender
unit assembly to a torque of 3.5 daN.m using the
tool Mot. 1264-01, holding the sender unit to pre-
vent it from rotating.
Make sure that the connector is firmly locked and
that the quick-release unions are securely clipped
on (with 2 O-ring seals)
Reconnect the battery.
CONNECTION
Disconnect the connector and the pipes on the
sender unit side.
Remove the mounting nut (5) of the pump and
sender unit using tool Mot. 1264-01.
Slacken the nut, remove the tool, unscrew the nut
by hand and remove it.
Remove the pump and sender unit assembly.
NOTE : If several hours may pass between
removing and refitting the pump and sender unit
assembly, refit the nut to the fuel tank to prevent
it from distorting.

ASSEMBLY
Special notes
Check that the seal is in good condition and re-
place it if necessary.
Fit the seal on the fuel tank first before fitting the
assembly.
Refit the pump and sender unit assembly in the
fuel tank by aligning it so that the indexing arrow
(F) is positioned in line with the longitudinal axis
of the vehicle, pointing towards the rear of the
vehicle.

Oil level sensor

98898R1
OPERATION
The sensor consists of a wire with a high
coefficient of resistance. When a current passes
through the wire it does not have the same
thermal conductivity when it is immersed in a
liquid as when it is in the open air.
After a fixed time a voltage difference is obtained
at the sensor terminals depending on the depth of
immersion of the wire. This voltage difference is
recorded by the electronic unit which manages
the level display function and also controls the
"low oil level" warning light display on the
central liquid crystal display.
When the ignition is switched on, the central dis-
play shows the oil level in a series of "blocks" for
approximately 30 seconds, before returning to
displaying the trip mileometer and total mileome-
ter functions (or "odometer" function).
NOTE : Turning the trip mileometer reset button
before the end of the timed period will display
the "odometer" function.
LOOKING FOR FAULTS
If a short circuit or an open circuit is detected
when the oil level is measured, the display will im-
mediately show the trip mileometer / clock dis-
plays.
CHECKING
The sensor resistance must be between 6 and 20
ohms.
The sensor is deemed to be in short circuit for a va-
lue lower than 4 ohms.
The sensor is deemed to be in open circuit for a va-
lue higher than 22 ohms.

OPERATION
A thermistor transmits a variation in resistance to
a receiver, depending on the coolant
temperature, and a threshold overshoot switch
illuminates the warning light on the instrument
panel when the temperature reaches 118°C.
CHECKING
Connect an ohmmeter between track 1 (K and E
engines) or track 2 (F engine) on the sensor and
vehicle earth.
Correct value : 160 to 1 250 Ω.

REMOVAL - REFITTING
Disconnect the battery and set the wheels
straight.
Remove the steering wheel and the two half cow-
lings (for vehicles with an airbag, refer to the re-
moval of the rotary switch on the following page
or section 88 for special notes on removing the
steering wheel).
Special notes for vehicles with an airbag
Before removing the assembly, the position of the
rotary switch under the steering wheel must be
noted:
- by ensuring that the wheels are straight on re-
moval so that the strip may be positioned in the
centre,
- by immobilising the rotary switch rotor using
adhesive tape.
Slacken the bolt (C) then sharply tap the screwdri-
ver to release the cone.

Special notes for refitting
Fit the mounting with its components, connect
the various connectors and push the assembly
back against the steering column.
Continue refitting and do not lock bolt (C) until
the two half cowlings are refitted, so that the
stalks may be aligned with the dashboard and the
instrument panel.
This operation is made easier by a cut-out section
giving access to bolt (C) in the lower half cowling.
For vehicles with an airbag, observe the re-
commendations in the section " Special notes for
the rotary switch under the steering wheel" on
the following page or section 88 (driver’s airbag).

and disconnect the connectors.
