I have a 2001 Tundra and it has the P0441 and P0446 codes pertaining to the EVAP system. To those who have had these codes pop up (or have experience with this) could you fill me in on what you did to fix it?
I've checked and replaced all the hoses I can find with cracks. A shop I brought it to supposedly smoke tested for leaks, and they said no leaks. But I found two more hoses with obvious cracks after the fact and replaced those. I tested the vsv's with a 9v battery to make sure they are still switching. Replaced the gas cap. Still getting the same codes. Also, not sure if this has anything to do with it, but my fuel gauge does not work. the low fuel indicator works though.
Here is all the information I got from my scan tool:

Can someone provide me with the EVAP system diagram? Or provide a link?
Thanks in advance!
