Yep, the lines look better. So the EVAP system needs to be 100 sealed, it cant have any leaks so please keep that in mind. Also, looks at the O ring seals inside the corrugated line on the solenoid. This video can show you how to check for leaks on the system.

O sorry, yes you squeeze the connector at the "loop" part this will release the connector without breaking it. Check out the images (below). Please let us know what happens.

So you still have this code?

Code: P0446 - EVAP Vent System Performance / Vent Control Fault

Lets check the ENG EMIS fuse in the fuse panel under the hood. This guide can help

Not really if the fuse is not burnt it is good. Can you check the gas cap seal, this is another point of failure for the sealed system. Keep in mind any leak in the gas EVAP system will cause this code as well.

The cable from the throttle to the gas pedal will not have anything to do with the EVAP issue. Can you see if the pink wire to the EVAP solenoid has power when the key is on?
