I -CHECKING THE OPERATION OF THE FUEL
VAPOUR ABSORBER BLEED
Check the conformity of the circuit (see 14A, Anti-
pollution, Fuel vapour rebreathing: Operation).
Check the condition of the pipes to the tank.
II - FUEL VAPOUR ABSORBER BLEEDING
CONDITIONS
The fuel vapour absorber bleed solenoid valve is
controlled by track 4 of the computer connector
when:
- the coolant temperature is above 60˚C,
- the air temperature is above 10˚C,
- the engine is not at idling speed,
- a given load threshold is reached,
- the throttle potentiometer is not in the « no load »
position.
During « on board diagnostic » fault finding, fuel va-
pour absorber bleeding is not authorised.
It is possible to display the opening cyclic ratio of the
fuel vapour absorber bleed solenoid valve using the
diagnostic tool by referring to parameter PR023: «
canister bleed solenoid valve OCR ».
The solenoid valve is closed at values below 3 %.

Note:
A fault with this system may result in rough idling
or the engine stalling.
