Evap Code P0446
Posted 08 October 2008 - 09:55 AM
I've previously had the mass air flow sensor replaced when I had the check engine/trac off lights come on about 2 years ago. After that replacement, all was well until now.
Any advice would be much appreciated!

Some people have said/thought a loose gas cap can trigger this code, but other say no way. On the RX300, the P0446 code is often a 'phantom code', meaning it shows up even when nothing is really wrong... then goes away (I've had that on my '99). One thing for sure, a new charcoal canister always fixes the problem. I don't know if that scenario directly equates to the ES300, but they sure share a lot of the same DNA.
