So it popped up last night. Got the code read this morning checked my gas cap its tight, did some searching found the blue T under the intake that's all connected. Checked the ends at the rear charcoal canister there on tight and no cracks. Anyone have a next place to look? 03 wrx stage 2 5spd 182k... stock intake and no smooth/one piece maf to turbo pipe.
I had this issue on my sti but I cant remember for the life of me what the part was called. I know it was at the front of the car and a valve was stuck open. My mpg was terrible and I'd get the code. I wish I was more help with remembering what the part was. The other thing you can try if nothing else works is a new gas cap. I have one that you can have if you need. Can you faintly smell gas outside of the car? I could with mine. Edit: I found this thread on nasioc.. check the things listed as I believe the purge solenoid was my issue. Evap valve? http://forums.nasioc.com/forums/showthread.php?t=2176865
Ill have to give it a look when I can the problem with this code is its anything from the gas cap to the tgv solenoid.
not sure of the part number, but its called the pressure control solenoid, its above the canister and looks like this... they are really common to cause a lot of different evap fail codes.
There was a recall on this for the 02-03 models back in 07 or something. Call subaru and see if your car has already had the recalled parts replaced and go from there.
