PO446 code

I have a code reading PO446 -
I know what the issue as far as it being a vent plugged on the charcoal cannister....any idea how to fix it?

Thanks!

do you "top off" at the gas pump? do you "round to the next dollar" ?? if so -- stop doing this. it clogs your EVAP system.

oops !

I'd recommend searching the Chevy Blazer forum for evap and vent. My guess is your vent solenoid but it could just be a clogged line. Disconnect and blow through ... also hook up 12volts and check that the solenoid is opening and closing. You may need to replace the whole canister but try the tests first.
