Evap Codes P0441 P0442 P0446

My 2003 Land Cruiser occasionally pulls a CEL for evap codes P0441 P0442 P0446. Any ideas where I should start looking? Cracked evap hoses? Failed valves?

Probably a failed vacuum switching valve (VSV). Check this out, the same principals apply:

Same year, same codes. Did you find a solution?

Unfortunately not. Never found it. I'm driving an '07 now that thankfully hasn't thrown any evap codes.

Long shot here, but do you find a solution?

I never did. The '03 was scrappd and my '07 has not thrown any EVAP codes.

So Im having the same codes. Replaced the charcoal canister twice and finally passed emission chicagoland only to have the code come back again. Smoking the EVAP system shows smoke coming out of the fuel filler neck area near a newer gas cap. Some have said to push hard on the gas cap and it will seal properly. Still working on this.
