Failure of the component

If the tank vent valve fails, the following behavior is to be expected:

• Fault entry in the engine control unit
• Emergency operation with substitute value

General notes 

If the oxygen sensors before the catalytic converter in cylinder bank 1 and cylinder bank 2 do not supply any plausible values, or a malfunction is diagnosed with both oxygen sensors, the tank vent valve switches to emergency operation. In emergency operation, the flow rate of the scavenging air depends on the engine speed and throttle valve position (lower than during normal operation).
