Hey guys I'm trying to help my son fix his truck but having a hard time without the books or equipment. The fault code we retrieve is a P0441. There are a few vacuum switching valves and a pressure sensor involved and the vapor canister. Does anyone have literature on this or some knowledge to put me in the right direction? Any help would be appreciated. The truck is a 2000 Tacoma, 3RZ-FE 2.7L 4 cyl. engine.
Thanks in advance, Pete
