How to learn more on check engine light
However, do not ever take your car to an auto parts store to have your check engine light checked out. Auto parts shop employees are not qualified to do anything beyond interpreting the trouble codes. For service done right, see your certified technician. Check engine lights can be triggered by such minor issues as a loose gas cap, bad spark plug wires or engine wetness. If your light signals a non emergency issue, check your gas cap and check your engine for wetness before going to the shop.
