What could a code 455 (EVAP Control System (Large) be on a 2001 Saab 9-5 2.3T? The car runs great. If you need any more details just ask.

Causes

A code p0455 most likely means one or more of the following has happened:

• A loose or improperly affixed gas cap
• A non-conforming gas cap (i.e. not factory/original brand)
• Other leak or damaged piece in EVAP system

Possible Solutions

With a p0455, the most common repair is to:

• Remove and reinstall the gas cap, clear the codes, and drive for a day and see if the codes come back.
• Otherwise, replace the gas cap, and/or
• Inspect the EVAP system for cuts/holes in tubes/hoses (you may hear a vacuum noise or smell fuel), repair if necessary

I got the code this morning.

After pulling the engine cover off, I noticed my ETS check valve is broken.

I'm kinda leaning towards this being the cause.

Of course, I can't find a universal replacement in the size though. Looks like I'll have to waste $50 at the stealership.

I'm a hair tweaked. This type of thing should NOT cost more than $10.
