Problem overview

There have been multiple reports of the check engine light illuminating. While there is no one solution, many of the codes associated with the check engine light are from the evaporation emissions or EVAP system. This may be addressed by tightening the gas cap and performing the appropriate drive cycle that can be found in the owner's manual.
