ALP 2 The fuel level indicator does not display full
NOTESThe fuel tank must be filled with the ignition switched off (advise the customer to remove
the key).
Ideally the customer must fill the tank with at least 15 litres.
See Wiring diagram Technical Note, New Twingo.
Ask the customer if the tank is filled up under the
following conditions:
–the customer filled the tank up to the 3
rd cut-out
–the customer has changed filling station
–the customer filled the tank in a flat-level station (not
on a slope).
Did the customer fill the tank while observing all of
these conditions?Ask the customer to return just after
having filled the tank under the conditions
mentioned above.

With the ignition off, disconnect the fuel sender
connector, component code 833 and then check
the resistance using a multimeter.
The value should be: 38 ΩΩ Ω Ω
.
Is the value measured less than 38 ΩΩ Ω Ω
?Replace the fuel sender, component code
833 (see MR 411, Mechanical, 19C, Fuel
tank, Sender: Removal - Refitting).
If the fault is still present, contact Techline.
Compare the value measured to the value supplied
by the CLIP tool.

Is the result of the check correct?Contact the Techline.
If the needle or display indicator test is incorrect,
replace the instrument panel, component code

ALP 4 Display jammed when driving (not mechanical)
NOTESOnly consult this customer complaint after a full check with the diagnostic tool.
For economical driving, the blocks on the display may remain illuminated or the needle
may remain jammed up to 120 miles (200 kms).
Check that there is no mechanical jamming.
If the fault is on the block at the top of the display or the needle is jammed at full:
check that the customer has travelled a sufficient amount of Km (miles) for the block at the top of the display to
go out or for the needle to move from the full section.
Check that the customer has not exceeded 3 filler cut-outs when filling the tank with fuel.
If the fault is still present or if the needle or the display is jammed in any position other than full, contact the Techline.
