What to do When Your Check Engine Light Comes On

As a car driver, chances are your check engine light has come on, and the best piece of advice is not to panic. It could mean anything from a quick fix to a serious engine problem. When it comes on, you should check other gauges and lights, tighten the gas cap, call roadside assistance if available, and reduce your speed. To lower the risk of a check engine service light appearing, be sure to take proper care of your engine. The next time your check engine light comes on, follow this advice to help your car recover as quickly as possible.

What to do if the check engine light comes on: Check all other dashboard gauges and lights, check and possibly tighten the gas cap, contact your vehicle's roadside assistance service (if available), and have the code read and the problem fixed. Reduce speed and load. If the check engine light is blinking or you notice any serious performance problems, reduce your speed and try to reduce the load on the engine. Have the car checked as soon as possible to prevent expensive damage.
