My car has started posting these Fault Codes P0441, P0442, P0446 at 1/2 a tank. I'll clear the codes then they will repost sometimes on the next tank or the next at 1/2 a tank. I have couple of questions. (Yes I have checked the gas cap.) :thumbdown: 1. does the ECHO only purge the system at 1/2 a tank ?? 2. Does the charcoal canister wear out ?? I am at 276,000 Km. 3. I have access to the 2007 Yaris manual is the 2004 EVAP system the same ?? Any hints or tips will be appreciated. :iono:
