Default P0441 Evap System -- could be PCV valve

My check engine light came on, and I got a code P0441 (Evap Emissions). Took it to the shop, since I can't diagnose it, and didn't want to deal with lowering the fuel tank (if it needed that). After quite a bit of diagnostic work, it turned out to just be a bad PCV valve! Shoot -- I could have fixed that!

So, just a note for future PT Cruiser owners -- a code P0441 could simply mean you need to replace your PCV valve. Save yourself a lot of time and money -- check it before you take your Cruiser to the shop!

Good PSA!
While you're at it make sure the hose is still supple and flexible. Most will be hard and cracked which will lead to rough idling if it starts sucking air through the cracks.

Hose for my 02 got real soft and gooey and had cracks in it. Junk yard is your best friend..... I replace my valves every couple years when I do a "tune up".
