The Check Engine light may be triggered by virtually anything affecting the monitored systems, from a simple loose gas cap or bad spark plug to an expensive computer control module or catalytic converter. While the check engine light will alert you that your vehicle needs attention, that is really all the information you can glean (unless you own a diagnostic code reader), initially.
If your gas cap is loose or the seal is not tight, the vapor leakage can cause your fuel system to trigger the check engine light. Many vehicles have a loose gas cap indicator that will be triggered before your check engine light comes on.

“Several excursions include stopping the engine and starting it once more. Thus, it involves more than simply one travel of 100 miles. In reality, it’s more like making three trips of each roughly 30 miles.
