CONDITIONS
aThe fuel vapour absorber bleed solenoid valve is
controlled by the computer.
During « on board diagnostic » fault finding, fuel va-
pour absorber bleeding is not authorised.
The opening cyclic ratio of the fuel vapour absorber
bleed solenoid valve can be viewed on the Diagnos-
tic tool by reading parameter « Fuel vapour absorb-
er bleed solenoid valve OCR » .
The solenoid valve is closed for a value below 1.2%. Equipment required

I - CHECKING THE FUEL VAPOUR ABSORBER
aOn the fuel vapour absorber, plug the circuit coming
from the fuel tank.
aConnect the pressure gauge of the (Mot. 1311-01)
to the fuel vapour absorber breather outlet.
aWith the engine at idle speed, check that no vacuum
is present at the fuel vapour absorber breather out-
let. In the same way, the control value read by the
Diagnostic tool in parameter « fuel vapour absorb-
er bleed solenoid valve OCR » remains minimal X
less than or equal to 1.5%.
Is there a vacuum?
-Yes: With the ignition off, use a manual vacuum
and pressure pump to apply a vacuum of 500
mbar to the solenoid valve outlet. The vacuum
pressure should not vary by more than 10 mbar
over 30 seconds.
•Does the pressure vary?
-Yes: the solenoid valve is faulty, replace it (see
17B, Petrol injection, Petrol injection: List
and location of components, page 17B-1) .
-No: if it is an electrical problem, check the circuit
(see MR 413 Fault finding, 17B, Petrol injec-
tion, Fault finding - Interpretation of faults,
Canister bleed solenoid valve circuit).
-No: In bleeding condition (see « bleeding
condition » ), the vacuum should increase. In the
same time, the value of the parameter on the Diag-
nostic tool increases.

TANK CONNECTION

uum and pressure pump to the pipe leading to the
fuel vapour absorber.Special tooling required
