– the valve remains locked shut; there is a smell of petrol,'
–the OBD warning light is lit.
CO.1Special note:
The valve remains locked open: bucking when driving, risk
of stalling and restarting difficulty.
Check that the fuseF8 (10A) is in good condition and is working correctly.
Repair if necessary.
Check the cleanliness and condition of the fuel vapour absorber bleed solenoid valve connections.
Repair if necessary.
Measure the resistance of the fuel vapour absorber bleed solenoid valve.
Replace the fuel vapour absorber bleed solenoid valve if the resistance is not 26Ω ±4Ω at 23°C.
Check for + 12 V on track 1 of the connector of the fuel vapour absorber bleed solenoid valve, with the ignition on.
Use the "Universal bornier" to check the insulation and continuity of the following connections:
Computer, connectorB, track M2 track 1 of the fuel vapour absorber bleed
solenoid valve
Protection and Switching Unit, connectorCN,

NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present with the engine running.
Special note:
This relay supplies the following actuators:
– the injectors
– the petrol fuel vapour absorber,
– the injection computer supply on track M2,
– the low-speed and high-speed fan assembly relays.
CO/CC.1: Actuators no longer supplied: the vehicle stalls and restart impossible.
CC.0: The actuators are supplied all the time: high electrical consumption when
stationary.
Intermittent CO: Intermittent relay cut-off: jerking while driving.
Disconnect the battery and the injection computer.
Check the cleanliness and condition of the injection actuator relay connections.
Check the cleanliness and condition of the UCH computer connections.
Repair if necessary.
Disconnect connector MN of the Protection and Switching Unit.
Check the cleanliness and condition of its connections.
Use the "Universal bornier" to check the insulation and continuity on the following connection:
Injection computer, connectorB, track D4Protection and Switching Unit, connector MN,
track 5
Repair if necessary.
If the fault is still present, carry out fault finding on the Protection and Switching Unit system (See87G, Engine
interconnection unit).
Contact the Techline.
AFTER REPAIRFollow the instructions to confirm repair.
Deal with any other faults.
Clear the stored faults.
