mferg Posted July 18, 2006 Share Posted July 18, 2006 I own a 2001 IS300. 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...

But I do have a thought... the EVAP is gas vapors... and the computer detects a leak somewhere... Might check out your gas cap... if its busted or loose... it could allow vapors to leak...
