Checking the ventilation and airing of the tank (Mondeo 3)

ORDER OF EXECUTION

Warm up the engine (to operating temperature) and let it idle.
Disconnect the low pressure hose coming from the activated carbon filter from the pressure reducing valve.
Check the valve connection to see if there is a negative pressure. If not, check the operation of the solenoid valve.
To do this, disconnect the wire from the battery and pull the plug out of the solenoid valve.
Disconnect the hoses from the solenoid valve and remove the valve. Mark the connection location first – this will make installation easier later.
Check the valve, if it is blown through, it no longer works.
