Another CEL P0446 question

[Rob175]

Spinjockey....If that's the case...will the gas remain there or eventually evaporate or flow into the tank to be used by the engine and return to a normal condition (ie: no more CEL triggering)?

Or…… would it be wise for me to loosen or remove the gas cap for a couple of days to hopefully let some of the trapped fuel in the canister evaporate??
Thx

You need to purge the lines. The gas won’t evaporate on its own and it’s effecting the rest of the evaporation system performance. You might have to replace your charcoal canister if it’s saturated. In general you should never overfill these cars because the evaporation systems are complex and unforgiving.
