Hey guys, been a long time since I've posted on here. I am starting this new thread because anytime I search for an answer I cant find anything pertaining to a 2005. My car is a 2005 WRX and I keep getting a trouble code for the evap system (either fuel cap loose/off, or small evap leak). Luckily I have the accessport so I can diagnose and clear the codes, however I am tired of it coming back every so often (when I highway drive I can get the car to cycle through the diagnosis test and it triggers the CEL). I have taken several steps in an attempt to diagnose the issue myself and Ive been unsuccessful thus far. I have replaced the gas cap with a new OEM Subaru part, I have checked all hoses and fittings connecting to the Purge Control Solenoid valve next to the intake manifold in the engine compartment, Ive even pulled the charcoal canister to inspect for split/cracked hoses and to check the pressure control solenoid mounted above. I modded the car about 8 years ago (Walboro fuel pump included), and never had this issue until about a year and a half ago. This is driving me mad as I keep my car meticulous and Im also due for inspection in about a month so I need to make sure the code doesn't keep re-occurring. The only other information I have related to this issue is that I can pick up on a faint scent of fuel when I am near the fuel door/passenger side rear area of the car. I understand that there are several moving parts involved in the evap emissions control system and I am fairly certain of the ones that I have ruled out so far. I can see that a good amount of people have experienced the same issues with their WRX. Any insight or suggestions are welcome Thanks in advance!!
