Check Engine Light

[mferg]

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

I'm not a mechanic... nor did I stay at a Holiday Inn Express last night... 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...

agreed but i did stay in a holiday inn express last year at Lex fest so that would make me an expert,i think
