[Shop-talk] Toyota question

[Tim .]

HI all

I am getting the following codes on our 02 Highlander:

440 Evaporative Emissions System
441 Evaporative Emissions System Incorrect Purge Flow
446 Evaporative Emissions System Vent Control Circuit I've been told that it
is probably the charcoal canister.  Can someone please confirm this and then
tell me if this is a fix I can do myself. I am more comfortable working on the
Datsun, not so much on newer vehicle.  Thanks!tim
