Question

My question i get a code my chevy impala and idont now. Code is P0449

Answer 1

P0449 Evaporative emission system  Vent control solenoid

The vent control solenoid is fused protected this is the first step check the fuse listed as CNSTR which is a 10 amp fuse, replace if open, If not the problem is with the vent control solenoid replace the vent control solenoid as soon as possible if left to itself too long it would cause more problems with its ECM driver
