Re: trouble code
That's not a result of your exhaust. The evap system takes fuel vapors from your fuel tank and stores them in a charcoal canister. When it's time for the engine to turn on, it purges those stored fumes in the canister into your engine to be burned. A few things that could cause your light to come on is not having the gas cap on tight, overfilling the fuel tank to where it is purging liquid fuel and not vapor or a faulty leak detection pump. Those are a few things that could be wrong.
