December 23, 201411 yr Hey Ya'll I have a new to me 97 Legacy Outback with the DOHC 2.5. I keep getting a p0441 DTC. I'm running out of ideas, so any ideas of things to check, please chime in! - Checked all the vacuum line connections, trimmed off a bit on each end and made sure there's a snug connection. - Sprayed each connection with starting fluid -- no change in idle. - Checked the purge solenoid. When hot wiring, it clicks. - Checked the Vacuum Switch Valve Solenoid, resistance is 41ohms - Checked the gas cap, sealed tight. - Checked the filler neck connection, seems free of rust - Checked the check valve @ the charcoal canister, seems to work Its driving me nuts! Any other ideas to check? Thanks!
December 23, 201411 yr Author what direction does the check valve on the charcoal canister go? Arrow towards or away from the fuel tank
December 24, 201411 yr Do you top off the gas tank when you fill up? Overfilling can cause this code, but it usually clears by itself in a couple of days. If you get it too often from overfilling, then the canister can be permanently damaged. Always stop on the first click.
