What to Do Next (Durmetric "Fail" Status without a Fault Code)

[thom4782]

I'm a Durametric novice. I've been playing with it for a couple of days now and working my way through any detected fault codes. The good news is that they are all gone with the fixes I've done.

I do have a question though. In the Engine Module, I found the following information when I checked the Ready function. It said fuel ventilation status fail. There are no fault codes associated with this. When I activate any fuel related subsystems, they seem to work.

So without more information, I am at a loss as what to do. I can add this piece of information. It's moderately hard fully fill the gas tank. Could this "fail" be related to the flexible fuel lines making the flap hard to open and close?

Thanks for any advice you can provide.
