Solve your P0446 easily: 1999 Toyota 4cyl 4runner EVAP Canister fix P0446 - YouTube
Had the P0446 for years. I read forums, chased down vacuum leaks, and tested canister valves - I did conclude it was the canister. But, I got into the habit of clearing the OBD and driving just the "right" amount of miles to pass emissions before the check light returned. Today, emissions test due, and I had tracked down a 4runner at a junkyard to go pull/buy the canister. Thought I would review a vid on replacement 1st and came across this as I was getting ready to leave. Did the spray test and bingo! I had leaks on both front corners! I really love fixing stuff vs. trashing it. JB plastic weld, passed emissions, exhaust literally smells better; and I'm confidant this was the cause of P0446 and a great solution.
