    Feeling a bit stumped. The CEL code P0446 keeps coming back after many miles from the last reset.

    What I have done so far:
    • Smoke test - no leaks
    • Tested canister, a couple fails, so replaced with OEM canister
    • New gas cap
    • New VSV evap solenoid
    • Checked vacuum lines
    Any ideas on what I might look at? Any other components that might cause the code?

    Much thanks.
