Q: Two codes coming up: P0449 & P0455

asked by on February 09, 2016

I am getting two codes: P0449 & P0455.

The most likely cause for these two codes is that the emissions control evaporative canister vent solenoid needs to be replaced. You may also want to check your gas cap to make sure it does not leak; it may be either of these components. I recommend having a mechanic, such as one from YourMechanic, start by inspecting the emission control canister, and work from there.
