The check engine light is one of the most enigmatic things your car does, because it pops on for a wide variety of reasons. We’ll help you figure out what the check engine light means, but if this doesn’t help you, you should take it to your dealership or mechanic.
The check engine light comes on when something goes wrong with the internal computer that controls and monitors a number of things going on under your hood including the engine speed, fuel mixture, and ignition timing. The check engine light can often be a case of burnt out bulbs, so if there’s anything obviously not working on your car, replace it and see if that makes the light go out.
The best way to figure out why the light is on is to read through your owner’s manual. You can go to an auto shop and have diagnostic testing run for free or buy a tester to run on your car yourself. The repair might be something simple you can do at home, but if it’s more serious, take it to a mechanic as soon as possible.
