    P0441 Evap purge flow

    CEL light comes on, code is in history, all vacuum lines are snug and tight, i clear code, CEL goes away, but when it comes back the code goes to history right away.

    any ideas?

    I think that is one of those codes that is "current" only while the PCM is commanding the purge solenoid open and it fails. Once the PCM removes the purge command, it goes to history. At least that's my suspicion.

    Checked all connections and vacuum lines connected to the Evap solenoid, and my PCV valves, all is tight and snug. Do these Solenoids tend to fail?

    I don't think it is a common failure, but anything can fail.
