P0440 error code OBD

Featured Replies

Can I get some good advice about a OBD code P0440. I know that it is the evap control sys but what do I do now??? Also I need to know where the different parts are located on the car. This is a 2000 Forester L. Please Help:

2000 Subaru ...... could be a rusted filler neck. Something to inspect.

 

Remove the passenger rear tire. Remove the plastic shield covering the filler tube, usually 2 or 3 small bolts. Then clean away the debris and look/smell carefully. The filler tubes DO rust through and post a P044x code.

 

Some have not replaced the cover after replacing the filler pipe. Their choice. I would prefer to remove it, clean under it and reinstall. Maybe make it part of the 60k service. The cover is there to prevent damage from road debris especially those pieces flipped up by the tires. So it does have a purpose other than to trap debris and cause the filler to rot.

You are the man!!!! After following your advice I found a small hole in the filler pipe. There was a lot of crap after removing the cover. Now I have to find a pipe and replace it. Thanks again.... Wicket

How did this work out for you? did the check engine light go off after you fixed the filler tube?
