Hey guys, so I have hade code P0449 on my truck for a while now haven't cared but now it's time for state inspection and I need to pass... so I have replaced the gas cap, evap solenoid by the gas tank and the purge valve on the intake... still have the dang code. Any one have any ideas? I'm guessing next step to trace all the evap lines and look for leaks? I don't have means of activating the solenoids unless someone can tell me what to check with a multi meter.
Edit: I also had p0455 but changing the one on the intake got rid of that code.
Thanks for any help
