mferg Posted July 18, 2006 Share Posted July 18, 2006 My check engine light came on yesterday and reading the codes revealed the following: P0440 (EVAP Emission Control System Malfunction) P0441 (EVAP Emission Control System Purge Flow Fault) P0446 (EVAP Emission Control System Vent Circuit Malfunction) Does anyone have any advice/thoughts on what this could be? The car runs fine, not noticeable issues/changes since the light came on. Thanks for any suggestions Mark Quote Link to comment Share on other sites More sharing options...

Some models have warranty on cannister and related part to 10yrs 150K miles. Hope this helps. Quote Link to comment Share on other sites More sharing options...
