It doesn't affect the car's performance or such. However, there should be extended warranties on emission systems. Double check with your nearest Honda dealership to get correct details but they should be able to check and fix it free of charge. That's if the light gets annoying. If you want to check it yourself. I'd start with the vacuum lines ot make sure there's no crack in them and then see if the fuel cap is loose. If that goes no where, I'd check the purge and vent solenoid since they can get plugged. Sometimes you may have to replace the EVAP canister.<br><b>References : </b><br> A lot of the emissions control system is just that. It doesn’t affect the car’s performance or such.
